GENUS PARORPHULA, N. G. 



Body more or less compressed, antennae in both sexes 

 "with the basal joints flattened, siibensiform in the female, a 

 little longer than (male) or about as long as (female) head 

 and thorax combined : the vertex between the eyes about 

 as broad as the smaller diameter of the former, horizontal, 

 with shallow depression surroundined by rounded walls; 

 angle of fastigium a little less than a right angle; lateral 

 foveolae not visible from above, elongate triangular; 

 frontal costa quite prominent between the antennae, rather 

 broader than diameter of basal joint, sulcate throughout; 

 pronotum with the median carina heavy, subcristate ; the 

 lateral carinae well defined throughout, the three cut by 

 last transverse sulcus a little in advance of the middle, pos- 

 terior margin angulate; tegmina and wings fully developed, 

 the apex rounded : hind femora moderately stout, in the 

 male surpassing, in the female about reaching, the apex of 

 abdomen; -hind tibiae with from 11 to 18 spines in outer row. 



In general appearance the insects of this genus resemble 

 some of the larger forms belonging to the genus Orpltulella 

 in North America, but on account of their subensiform 

 antennae, infuscated wings, and well develojjed median 

 carina of the pronotum, they api3roach more closely to the 

 genus Or pin (1(1.
