sertion in its proper place in the Synopsis. It belongs to the Subfamily Encyr- 

 tinse. and is closely allied to Homafotyliis (p. 69), but differs chiefly as follows : 

 The pedicel of the antennse is much hmgcr than the fii-st funicle joint; the inner 

 margins of tlie eyes are nearly parallel ; the stigma' vein of anterior wings bends 

 abruptly downward, forming at first a right angle with the submarginal and 

 afterwards curving slightly outwards; the postmarginal vein is absent, and the 

 large mesopleura is covered with a number of longitudinal ridges. Male not 

 known.
