wholly testaceous. They are crepuscular or nocturnal insects, and 

 can be captured by beating the trees. 



The specific study of the 2^ South African species known to me is 

 extremely difficult. An examination of the genital armature of the 

 males, as figured in plate xli. will, however, easily lead to their 

 identification, but all the females are extremely alike. I have had 

 no difficulty, however, in identifying both sexes by means of the 

 locality, for a glance at the habitat of the species shows how 

 restricted is their area of distribution in South Africa, and so far 

 as I know A. fuscij^es is the only one having a somewhat wide 

 range, for it occurs in the Orange Eiver Colony, in Buluwayo, and 

 Mazoe in Southern Ehodesia, and also in Northern Damaraland. 



Key to the Species. 



A-. Inner claw of the anterior tarsi somewhat slender in both 

 sexes. 



B'*. Inner claw of the anterior tarsi onh' cleft in the male and 

 in the female. 



P'erruginous red, elytra piceous and with a narrow red- 

 dish margin ; prothorax closely aciculate ; clypeus very 

 narrow, broadly refiexed ; intervals of elytra conspicuously 

 coriaceous (pi. li., fig. 26) nigrocextita. 



B3. Inner claw of the anterior and intermediate tarsi simple 

 in the male, cleft in the female. 



a-. Elytra piceous. 



Piceous with the frontal part of the head and the 

 antei'ior legs reddish ; prothorax indistinctly acicu- 

 late ; clypeus narrow, hollow, and broadly reflexed ; 

 intervals of elytra smooth (pi. li., fig. 27) vetnla.

 prothorax almost impunctate, and without any 

 median impression (pi. li., fig. 29) damarn. 



h'. Anterior tibiee bi-dentate.
