The preapical bristles of the scutellum vary from 3 to 7 
in 143 specimens examined (79 $ and 64 $ ), from 23 lo- 
calities, 126 specimens having 5 or 6 bristles. The several 
numbers are represented as follows: with 3 bristles: 1 
( $ ) ; 4b. : 3 (1 $ , 2 $ ) ; 5b. : 19 (11 $ ,8 $ ) ; 6b. : 107 
(60 $ , 47 $ ) ; 7b. 13 (7 $ , 6 $ ). There is apparently no 
sexual difference in this character. The number from any 
one locality is too small for further analysis. The bristles 
are evenly divided in 110 specimens, unevenly in 33, the 
uneven groups observed being 1 + 2, 2 -]- 3, and 3 + 4. 
H. longipennis differs from H. equina in the shape of the 
tergal plates of the abdomen, the difference being more 
striking in the male than in the female. In the female of 
H. longipennis the three median, setulose sclerotized plates 
are very small, ovate or reniform, the second smaller than 
either the first or the third, the third much smaller than 
the anterior pair of subapical (lateral) plates. In the male, 
the three median plates are large and ribbon-like, much of 
the same shape as in the male of H. equina ; but the hind- 
most (or third) plate is connected laterally with a pair of 
small, attenuated lateral subapical plates (recognizable by 
their bearing longer setae than the median plate proper) . 
No adequate figures of this species have been published. 
The claspers (or parameres) of the male genitalia are 
very similar to those of H. equina.
