64 Mr. R. E. Turner on New Species of 



the mesonotum ; median segment very coarsely rugose, the sides 

 finely and closely striated. Abdomen smooth and shining, petiolate ; 

 the first segment as long as the second and third combined, very 

 narrow at the base, the apical half moderately swollen and slightly 

 constricted at the apex; the second segment twice as broad at the 

 apex as at the base; the recurved apical spine of the hypopygium 

 rather short. First recurrent nervure received just before one- 

 quarter from the base of the second cubital cell, second just before 

 one-third from the base of the third cubital cell. Third abscissa 

 of the radius as long as the second and first combined, second fully 

 twice as long as the first.

This is distinguished from other known males of the 

 genus by the black basal and red apical segments of the 

 abdomen ; the anterior margin of the pronotum is raised, 

 which is not the case in glabricollis, Diicke, or confusus, Sm, 



Family PSAMMOCHARIDAE. 



The two following species belong to the wide-ranging 

 genus Episyron, in which the tarsal ungues are bifid in 

 both sexes, the cubitus of the hindwing originating just 

 before the transverse median nervure, the third cubital 

 cell much shorter than the second and strongly narrowed 

 on the radius, the first dorsal segment clothed more or less 

 densely with scale-like hairs, and the male antennae rather 

 slender, with the joints not arcuate beneath. The labrum 

 is slightly exposed.

This is a true Episyron, nearly related to the European 

 P. rufipes, the type of the genus. It is very closely related 

 to the New Guinea species E. papuensis, Sm.
