$. Although ZH. capitalis has been regarded as only a smaller race of H. majuscula 16, 
yet it may, from the material now examined, be regarded as specifically distinct on 
the structural character (mentioned in part by de Selys*) of the superior appendages 
of the male (¢f. our figg. 21 and 23); and in the presence of only two rows of cells 
between the second sector of the triangle and the hind margin of the hind wings, while 
there are three rows in H. majuscula. 
Other differences stated from time to time are not so constant. Thus as regards size, 
that of the present material, added to the recorded measurements ?, shows that the 
abdomen of H. capitalis, 3, varies from 35-44 mm., and the hind wing, ¢, 28- 
33°5 mm. (the latter figures from the Sta. Fé de Bogota male). ‘The corresponding 
figures for H. majuscula, 3, are: abdomen 46-48, hind wing 35-37. ‘The red of the 
basal spot of the front wings invades a considerable part of the costal space iu the 
males from San Gerénimo and Chiriqui. The pterostigma varies in length, even in 
the wings of the same individual, the extremes being the surmounting of two cells (San 
Gerénimo), and existing as merely a thickened, more oblique postcubital (Zapote). 
?. The two females trom Zapote fall within the previously known size-limits : 
abdomen 32-36 mm., hind wing 28°5-32. The stripes on the sides of the thorax are 
metallic green, not blackish. The tip of the dorsal carina on segment 10 is bifid or 
trifid; on either side of it, at a short interval, is an acute tooth, projecting from the 
hind margin of the same segment, much as in #. tricolor. 
The single broken female of H. majuscula seen does not admit of any statement as 
to possible specific differences in this sex other than the size.
