29. GENUS HEBETICOIDES FOWLER 



Hebeticoides Fowler, B. C. A. II : 52 (1894). 



Characters : Fowler describes this genus as intermediate between Hebetica Stal and the old 

 subgenus Leptosticta Stal (now a synonym of Stictopelta Stal), separating it from both by the venation of 

 the corium. This is a correct distinction but the venation is no different from that oi Darnis Fabricius 

 and in general facies the insects agree with both Darnis and Ochrolomia. This leaves as the only struc- 

 tural character available for taxonomic use the relative proportion of the tegmina exposed below the 

 pronotum. We do not consider this a very reliable generic character but since the tribe is large and 

 subdivisions are helpful in classification, we are here recognizing Fowler's arrangement. 



In general the insects of this genus resemble those of Darnis. The pronotum is smooth, shining, 

 with weak punctuation and no carina. There are no frontal, dorsal nor humeral processes of any kind. 

 The posterior process is long, acuminate, extending backward farther than the tips of the tegmina. 

 The head is subquadrate, twice as broad as long, with the clypeus truncate and not extending below 

 the inferior margins of the genae. The tegmina are narrowly and evenly exposed for about one-third 

 of their width below the lateral margins of the pronotum.

30. GENUS OCHROLOMIA STAL 



Ochrolomia Stal, Hem. Fabr. II : 32 (1869). 



Characters : Erected as a subgenus by Stal particularly on account of the position of the ocelli 

 which are very much nearer to each other than they are to the eyes and because of the short posterior 

 process, and elevated to generic rank by Goding (1894) on the strength of these same characters. 

 In other respects, and particularly in the matter of general superficial appearance, the species of 

 Ochrolomia greatly resemble those of Darnis. 



The insects are medium to large in size; the pronotum is smooth, glistening, often marked with 

 brilliant fascia, and without processes of any kind except the posterior projection which is relatively
