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

 tinae, and is closely allied to Ilomaloti/his (p. 69), but differs chiefly as follows: 

 Tbe jiedieel of tbe anteniue is mucb longer than tbe first f'uniele. joint ; tbe inner 

 margins of tbe eyes are nearly parallel ; the stigmal vein of anterior wings bends 

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

 afterwards curving slightly outwards; tbe iiostmargimil vein is absent, and tbe 

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

 known.
