124 Lonyicornia Malayana. 



Besides these the late M. Mouhot obtained three species in Cam- 

 bodia, which were published by me as yJgelastce, but only one of 

 which can be retained in the genus as here defined.* I have 

 also species in my collection from Pulo Penang and from Patani 

 in Malacca,-)- and another from Java, unpublished, is the Choero- 

 morpha pigra of Dtjean's Catalogue. The species with scarcely 

 an exception are remarkably distinct, and, omitting one, which is 

 only placed here provisionally, the genus, as now limited, is a 

 very natural one. Nevertheless there are certain peculiarities 

 which it may be well to notice. In J. irrorata, there is a very 

 decided process on the side of the prothorax, not exactly a tu- 

 bercle or a tooth (as in ^. Poljjnestts), and there is a little angularity 

 also in A. sohrina and A. sulphurea. 'J'he male A. Wallacci has the 

 antennae scarcely longer than the body, while in A. subrina they 

 are half as long again. In the male of a species from Penang 

 (not yet published), and apparently so closely allied to A. Wallacci

Agelasta lar. 



A. ni;:^ra, nitida, pube albida interrupta tenuiter tecta ; antennis pedibusque

Uah. Malacca (Patani). 



Black, shining, with an interrupted thin whitish pubescence, giving the 

 prothorax, and especially the elytra, a very mottled appearance; prothorax 

 almost as broad as the elytra, rather irregular at the sides ; elytra short, with 

 shallow dispersed punctures, principally at the base; body beneath and legs 

 blackish, with a pale grey pile; protibia; nearly as long as the elytra ; tarsi 

 whitish, the claw joint dark brown, except at the base ; antcnnx half as long 

 again as the body, darkish, the bases of the third to the sixth or seventh 

 joints paler.
