Coleopterous Family Dennestidse. 431 



Trogoderma tricolor, sp, n. 



Ovale, parum elongatum, nigrum, vix nitidum, elytrorura apicibus 

 Ifete rufis ; crebre punctatum, minute griseo-setosum, pronoti 

 lateribus et lobo postico elytrorumque fasciis tribus, plerumque 

 late interruptis, albo-squamosis, pedibus antenuisque rufis, illis 

 longis, his sat brevibus, clava triarticulata, ovali, articulis duobus 

 penultimis brevissimis. 



Long. 3 mm. 



Hah. Arabia: Yemen {Milltngen). 



This interesting species is very different from any other 

 known to me. The white spots are composed of long pointed 

 scales^ not fitted together edge to edge as in Anthrenus, but 

 free at the end and massed in thick loose clusters. The legs 

 are long and not capable of being closely folded up as in that 

 genus, and although there are cavities in theepisterna for the 

 reception of the antennae they are not very sharply defined 

 and coincident with the antennae. The club of the latter is 

 broadly oval and flat, consisting of three transverse joints, 

 the last of which is not quite twice as long as the other two, 

 wJiich are very short. In a series of seven specimens, whicii 

 I believe to include both sexes, I can see no perceptible 

 difference in the antennae.

Hab. Rhodesia: Salisbury, LTmtali. 



Three specimens were taken by Mr. G. A. K. Marshall 

 and presented by him to the British Museum. 



The species resembles T. tricolor, but it is larger and more 

 oblong in shape, and the white spots, of which there are only- 

 two ranges instead of three upon the elytra, are formed of 

 fine hairs, and not of scales. There are also two conspicuous 

 red patches upon each elytron, the first transverse and placed 

 behind the shoulder, the other nearly round and occupying
