I'liis has been found by various collectors, but apparently 

 nowhere in any numbers. Specimens from Mpeta, on the 

 Ivoangwa Rivor, have boen received by Dr. Ohaus, of Ham- 

 burg. This species also is related to A. oariegataSj in which 

 tjie prothorax is similarly decorated. But it is more closely 

 connected with another Adorelus occurring in Natal which 

 Mr. P^ringuey has identified as the Eriesthis hopUoides of 

 Bohenian. A. albolepidus differs from that form (of which I 

 liave examined three specimens taken by different collectors 

 in Natal) only in the nature of its clothing and the more 

 conspicuous white ornamentation. The covering of the new 

 species consists of creamy- white scales, of which some are 

 larger and wliiter than the rest, while A. hopUoides^ Boh., is 

 clotiied with a uniform fine grey pubescence, nowhere 

 assuming the form of scales. 



Adovetus jjlumbi'collifi, sp. n. 



Cylindricus, angiistus, niger, elytris rufis ; clypeo magno, semi- 

 circulari, griseo liirto, t'roiito piUs erectis aurantiacis vestita ; 

 protborace elytrisquo griseo-pubesceutibus, pilis longioribus 

 erectis iuterpositis, illo valde trausverso grosse punctato, lateribus 

 angulato-arcuatis, angulis anticis acutis, posticis obtusis ; elytris 

 puuctato-rugosis ; corpore subtus pedibusque nigris, sparse griseo- 

 liirtis, tibiis anticis acute tridentatis.

 Lake Nyasa [Tlieiwall). 



This insect is also represented in Dr. Ohaus's collection as 

 well as in that sent to us by Mr. Marshall, while two specimens 

 from Lake Nyasa have been in the British Museum since 

 1877. It may be readily identified by several very distinctive 

 features. Its long narrow form, the stiff golden hairs upon 

 the head, the narrow black thorax (to which, with the under 

 surface, the thin clothing of grey hairs gives a leaden appear- 

 ance) are all peculiar to it and separate it rather widely from 

 all other known species of the genus.
