One example with the abdomen missing. From a 
comparison with specimens in the Oxford Museum, I am 
convinced that this species of De Geer’s is merely the 
male of HL. abdomen-nigrum. The differences between the 
two specimens are, irrespective of size, very trifling, e.g. 
in Blatia livida, the mediastinal vein is triramose, there 
are only 10 costals, the legs are testaceous, and there are 
only 4 spines on the anterior margin beneath of the front 
femora and 3 on both margins beneath of the other pairs. 
Total length 19 mm.; tegmina 15 mm.; pronotum 
5mm. X 69 mm. 
Also recorded from Surinam. The unique specimen 
bears a label in Stal’s handwriting “ Epilampra brasiliensis, 
Burm. var.”

This species also is omitted in Kirby’s Catalogue.

bifurcate, 16-18 costals, 11 longitudinal discoidal sectors, both the

hyaline, exceeding the sub-genital lamina in length, sparsely 
fimbriate. Abdomen beneath castaneous, sub-genital lamina semi- 
orbicular, ample. [Cerci mutilated.] Legs testaceous, tibize rather
