In Mr. Wallace’s private collection of Malayan Hetero- 
merous Coleoptera, now in the Hopeian Museum at 
Oxford, were a number of specimens which at first sight 
seemed to belong to the genus Pseudolycus of Guérin, but 
which differ from the species of that genus as well as from 
Nacerdes, &c., in the remarkable structure of the maxil- 
lary palpi of the male. They may be divided into sections 
as follows— 
A. Antennz concolorous. 
a. Flagelle of the maxillary palpi of the males 
equal: sp. 1—10. 
b. Ditto, unequal in size: sp. 11. 
B. Antennz with several of the terminal joints pale- 
coloured: sp. 12, 13. 
The insects of the first subdivision agree entirely in 
their general form and structure, and it is with great 
doubt that I give them as distinct species, and yet I can 
scarcely conceive them to be varieties of a single extremely 
variable species. 
Species 1. Danerces lutetcornis. 
Tota luteo-fulva, opaca, elytris (basi apiceque exceptis) 
nigricantibus, velutinis, antennis luteis; corpore infra luteo- 
fulvo, abdomine piceo, segmentorum marginibus lutes- 
centibus.
