II.—Some new Species of Odonata of the “Légion” Lestes, 
with Notes. By Ropert M‘Lacutay, F.R.S. 
Most of the species described in this paper have been in my 
collection for years, and form a small portion of the unde- 
termined materials in the “ légion”’ that I possess. 
OrRTHOLESTES, Calvert. 
This genus was originally described by Mr. P. P. Calvert 
(who is doing most excellent work in American Odonata) in 
the Ent. News, vol. 11. p. 199 (1891), to receive an insect 
from Jamaica which he termed O. clara, In the Proc. Acad. 
Nat. Sci. Philad. for 1893, pp. 377-383, he amplified the 
original description for both genus and species, and added a 
second species from Haiti, which he termed O. Abdott?, the 
two being evidently much allied, and the latter known by 
only one male. 
I have long had many males and four females of an Ortho- 
lestes from ‘Samana Bay, 8S. Domingo.” According to the 
locality these should be O. Abdotti, but they agree better with 
the description of O. clara, only the “ more apical” tooth of 
the superior appendages, instead of being “ slightly notched,” 
is distinctly bifid (but not deeply so), the t upper portion usually 
slightly longer and distinctly more slender than the lower. 
Of O. Abbott it is written that “‘the more apical tooth is 
transformed into a slender acute curved spine.” I think that 
insects of the same lot from Samana Bay received by 
%
