sides ; tarsi somewhat short and robust, posterior ones not longer 

 than the hind tibiae ; claws unequal, parallel, inner one of the 

 anterior tarsi and outer one of the intermediate ones cleft at the 

 tip ; each coxae produced behind at the base in a more or less long, 

 but nearly always very distinct lobate process ; mesosternum not 

 projecting in front. 



The species are usually covered with short, appressed hairs, at 

 times somewhat squamiform, but never dense enough to hide com- 

 pletely the teguments ; several species have series of remote, upright 

 hairs on the elytra, and the lateral margins have a fringe of bristly 

 ones always longer in the anterior part. They are found on trees 

 and are crepuscular. Near Kimberley I found many examples 

 hidden a few inches under the surface of the ground, at the foot of 

 tlie trees dotting the landscape. The genus has a wide range. It is 

 represented in the whole of Africa, in Madagascar, Arabia, India, 

 China, Java, Manilla, &c., and there is also one species in Southern 

 Russia. The African species are very much alike, but all those I 

 know can be somewhat easily recognised by the shape of the genital 

 armature of the male. 



Key to the Species. 



A5. Clypeus regularly rounded from eye to eye in both sexes. 

 B-. Trochanters of hind legs spinose in the male. 



Chestnut-brown, covered with dense greyish hairs. 



Suture of the clypeus with the head very plain, scutellum 



closely punctured, hind trochanters produced into a very 



long spine (pi. li., fig. 1) capicohi. 



Suture of the clypeus hardly distinct ; scutellum with only 

 a few punctures, hind trochanters produced into a short 

 spine (pi. li., fig. 2) /alliiciosit:^. 



B'. Trochanters of male not spinose. 



a3. Elytra not distinctly costulate. 



Chestnut-red, clothed with white concolorous hairs ; f incoiinnieiia.

Fuscous brown, densely clothed with white scale-like 

 hairs, and having on each side four i"ows of granules 

 bearing each a white bristle (pi. li., fig. 4) 2)uuctij)e)iiih 



Fuscous with the elytra dark chestnut-brown, sparingly 

 clothed with greyish hairs ; clypeus very elongate(pl. li., 

 tig. G) salisburicimis. 



n'. Elytra with only one distinct costule on each side. 



Dark chestnut-brown ; prothorax with three con- 

 spicuous bands of white scales, scutellum clothed with 

 similar scales (pi. li., fi .5) ho})lioidiK.
