brown transverse l)aiul only just reacliinf? into tlie anal cell 

 and not attaininfr the apex of the discal cell ; it is very similar 

 to that of C. ciliaris, Loew. 

 Length 8 millim. 



Chrysops trimaculatus, ? , Bigot. 



Type (female) and one other female, both in bad preser- 

 vation, the type on a card. 



This species is distinguished by a singularly narrow fore- 

 head for a species of this genus ; there is a triangular space 

 in front, its base being the narrowest part of the forehead ; 

 the eyes approach very closely, receding a little on the vertex, 

 leaving a small triangular space on which the ocelli are 

 placed. For first segment in Bigot's description read second 

 segment. So far as can be judged from the specimens, the 

 third segment seems wholly black and the fourth almost 

 wholly yellowish red. On the underside of the other female 

 (not the type) the second segment is yellow, and there is 

 some reddish-yellow colour on the third and fourth. Wings 

 with the basal cells infuscated on their basal half; the trans- 

 verse band reaches the hind border, extending to the apex of 

 the anal cell, becoming fainter in colour in the fourth and 

 fifth posterior cells ; the apical spot is narrow, reaching to the 

 apex of the wing.
