cc. Bisected by a mere line; facets larger abovo the line than 



below. — lAp. yosemite cf (0. S. observed in lue), 

 ccc. Not bisected; facets of an equal size. 



Ljrp.(?)^ Palt., Snoivia. 



NB. Both females, described by Dr. F. M. as bloodsucking 

 (Snowia) and flowersucking (of a still doubtful genus), 

 have the eyes separated by a broad front, but the eyes 

 of the former are described and tigured (fig. 14, head) as 

 larger than the eyes of the latter (tig. 13, head). 



I place Li}), ein., brevic. and biloh. in the division ccc 

 with a query, because I have no positive data about 

 tbeir eyes. 



Apist and Lip. yosemite are two very rare instances 

 of bisection of the eye connected with a dichoptic 

 head. As a rule, it occurs only in holoptic heads. 



Proboscis. Long: Apist.., Palt.., Hamm. 



Short: Bibioc, Agathon, Bleph., Lip., Snowia, Ou- 

 rnpira, Hapal. 

 Palpi. Compare above, under § A. 



Legs. Their proportions vary in different genera and species, but, 



as already stated (under A), the last pair is always the longest. 



In some cases the bind femora are somewhat incrassated {Bleph. 



fasc, Lip. yos., Snoivia). 

 In Hamm, the middle pair of legs is remarkably short. 

 In Bibioc. and Apathon the fore coxae are somewhat distant froni 



each other; in Bleph. and -Lip. much less. 

 In Lip. ein. cf the bind tarsi are short, about half as long as the 

 tibiae; this is principally due to the shortness of the 4^ Joint, 

 which is much shorter than the fifth. 

 Bibioc. has the front tibiae somewhat curved; the closely related 



Agathon has them straight. 

 The last Joint of the tarsi is subject to different variations. In 

 lÄp. ein. cf it is hollowed out on the underside, and provided 

 at the proximal end of the curvature with a bunch of short hairs. 



plare della collezione" (Loew, 1869, p. 100). But bis specimen was 

 a 5, in vvhich the difference, as Bigots figure reprcsents it, issmall. 

 According to Verrall, in the c/, the ditference is quite striking. It 

 is also worthy of notice that the iinfacetted stripe across the eye 

 is not raentioned at all in Bigot's description, and tbercfore that 

 the Statement of Loew about it reposes nierely on ils delineation in 

 the figure.
