¶3Before BREYER, Chief Judge, ALDRICH and COFFIN, Senior Circuit Judges.
¶5A jury convicted James Chambers of six counts of bank robbery, 18 U.S.C. § 2113(a), and the district judge sentenced him to 216 months in prison and thirty-six months of supervised release. Chambers appeals his convictions, claiming that the district court prejudiced his case when it permitted a joint trial of the six counts, under Fed.R.Crim.P. 8(a), and when it denied his motion to sever the counts, under Fed.R.Crim.P. 14. We find no error on the part of the trial judge, and we affirm the convictions.
¶6The court permitted the counts to be joined pursuant to Fed.R.Crim.P. 8(a), which provides that
Two or more offenses may be charged in the same indictment or information in a separate count for each offense if the offenses charged, whether felonies or misdemeanors or both, are of the same or similar character ...
¶7We review joinder under Rule 8(a) de novo, as a question of law. See United States v. L’Allier, 838 F.2d 234, 240 (7th Cir.1988). In this case, we find that the similarities among the six charged offenses are more than adequate to meet the Rule’s standard. Each of the six robberies involved a similar institutional victim — a federally insured *1251bank. All the robberies occurred in a short period, between May 1 and July 14, 1989, and in a limited area, the greater Boston area. The six tellers who were robbed testified at trial, and each described a similar modus operandi during the robberies, with the robber always wearing a hat or cap, always threatening violence with a bomb or gun, and always giving the teller a handwritten note demanding money in basically the same language. In such a case, involving similar counts, institutional victims, mode of operation and time period, joinder is proper. See United States v. Gray, 958 F.2d 9, 14 (1st Cir.1992).
¶8Chambers insists that, even if joinder were not improper under Rule 8(a), he was severely prejudiced by the district judge’s denial of his motion to sever under Fed.R.Crim.P. 14. That Rule provides, in relevant part:
If it appears that a defendant or the government is prejudiced by a joinder of offenses ... the court may order an election or separate trials of counts, ... or provide whatever other relief justice requires.
¶9We review the district court’s denial of this motion for abuse of discretion. See United States v. Olivo-Infante, 938 F.2d 1406, 1409 (1st Cir.1991). Chambers has failed to make a strong showing of prejudice. See United States v. Font-Ramirez, 944 F.2d 42, 45 (1st Cir.1991); United States v. Scivola, 766 F.2d 37, 41 (1st Cir.1985); United States v. Clayton, 450 F.2d 16, 18 (1st Cir.1971). He asserts that he was prejudiced by the fact that none of the bank tellers made an in-court identification of him, and that the jurors were therefore left to evaluate the counts collectively, and to cumulate evidence illegitimately on the various counts.
¶10Each of the tellers, however, gave a similar general description of the robber which matched Chambers’s appearance. Three of the tellers identified Chambers from surveillance photos taken during the robberies, and two of them picked his picture from photo line-ups prepared by law enforcement agents. Moreover, when the prosecution introduced four of the robber’s notes to the tellers, it accompanied them with expert testimony that assessed each note separately. Experts from the Federal Bureau of Investigation identified the fingerprints on two of the recovered notes as Chambers’s, and a handwriting expert, comparing the handwriting on the four notes with known samples of Chambers’s writing, said they were all written by Chambers. Furthermore, the district judge was careful to instruct the jury that the prosecution had to prove each element of each count beyond a reasonable doubt, and that the jury was to consider the evidence on each count separately. Cf. L’Allier, 838 F.2d at 242.
¶11Given the evidence and the instructions, there was no real danger that the jury would be confused or would illegitimately cumulate the evidence. See Gray, 958 F.2d at 14-15; see also Clayton, 450 F.2d at 19; United States v. Johnson, 820 F.2d 1065, 1071 (9th Cir.1987).
