132 Psyche [August 



Described from one specimen. The three species, Meijere's, 

 Theobald's and this he very close together, the color of the iridescent 

 scales on the head and mesothorax being a possibly misleading 

 characteristic, but the scutellum in this species is white scaled 

 only on the mid-lobe, the scales on the lateral lobes being not only 

 brown but smaller than those on the midlobe, and while this is a 

 small difference it may serve to separate it from the others. 



As I have only one specimen it has not seemed wise to dissect it, 

 but the mouth parts as described by Meijere^ and the peculiarities 

 of the clypeus as noted above seem to me to be of more than 

 generic value. The insect of course comes under Lutz' group 

 Ctdicimorphce, for though the proboscis is long, the lack of develop- 

 ment of the maxillae and mandibles into the long processes found 

 in what Lutz calls the Euculicidce prevents the insect from using 

 it as a piercing instrument. It, however, seems quite distinct in 

 its peculiarities, and as I prefer to keep all the forms with Culicid 

 wing venation under the Culicidw the only way seems to be to create 

 a new sub-family. I therefore propose to call this sub-family 

 HarpagomyincB n. sub-fam. with Harpagomyia splendens Meijere 

 as the type for genus and species.
