Type species: Rhopaloceras sty lifer (Nitzsch, 1818) (A synonym 

 of Pediaulus meleagvidis Linnaeus, 1758).

Type species: Triohomedea setosa Carriker, 1945a. 



Clay (1941) considers the form of the male clavus as the most con- 

 stant and typical generic character. Male clavi transparent and consist 

 of a basal portion prolonged distally into a fine point; in the female 

 the clavi are normal. In knovm species the antennae are sexually di- 

 morphic, the male having the distal pre-axial angle of the 3rd seg- 

 ment produced. Pterothorax quite large with straight divergent lateral 

 margins and a central sternal plate bearing hairs. Abdomen elongated 

 and somewhat pointed posteriorly with segment I (true segment II) small 

 in both sexes. Segments VIII and IX (true segments IX and X) of male 

 are fused and elongated in an anteroposterior plane. In this genus the 

 genital opening is ventral. Paratergal plates well marked with compli- 

 cated re-entrant heads.

This is the only species of the genus found in New England. It is 

 easily distinguished from all other species of the genus by the temples 

 in both sexes being greatly prolonged distally. It has been reported by 

 Wilson (1928) from New York, Peters (1928) Ohio, Brimley (1938) North 

 Carolina, Emerson (1940) Oklahoma, and by Brown and Wilk (1944) from 

 Alberta.
