Endomychid Coleoptera of Indo-China. 329 
identical coloration, produces a marked resemblance to that 
genus, although the relationship is remote. 
The pronotum is relatively rather narrow, with the sides 
approximately parallel, very feebly curved but a little dilated 
towards the base, and all the angles slightly produced. The 
four pale elytral spots are similar in size and shape to those 
of E. westwoodi and alboguttatus, but rather more transverse. 
The narrow elytral margins are as in those species, but the 
greatest width of the elytra is across the dilated shoulders. 
In a single specimen from Pou Bia the pale spots are 
reduced to narrow transverse bars. 
Indalmus kirbyanus, Latr. Luang Prabang, Pak Lay, 
Xieng Khouang, etc. .This is a common species, widely 
distributed in India and the Malay Peninsula. 
Ancylopus melanocephalus, Oliv. Although M. Vitalis has 
only found a single specimen, this is probably the commonest 
of all the Endomychide, found almost all over the Old World. 
Cymbachus elegans, sp. 0. 
Niger, nitidus, elytris violaceis, utroque maculis magnis duabus 
flavis ornato, prima humerali aliaque subapicali, his maculis 
rotundatis, vix ad margines externos attingentibus; ovalis, 
convexus, pronoto subtiliter irregulariter punctulato, lateribus 
leviter bisinuatis, angulis productis, anticis haud acutis, posticis 
acutis, foveis basalibus subtilibus ; elytris paulo fortius punctatis, 
humeris modice prominentibus, lateribus leviter arcuatis, apicibus 
paulo attenuatis ; antennis haud gracilibus, clava lata. 
Long. 7 mm. ; lat. max. 4 mm. 
Inpo-Cuina : Upper Mekong R., Nam Long (R. Vitalis 
de Salvaza, April). 
Only one specimen of the species has been found. 
The body is less short and broad than in either of the two 
species of Cymbachus hitherto known. The pronotum is 
narrower, with all the angles rather more produced, but the 
front ones blunter. The elytra have the shoulders only 
moderately prominent and the sides gently and regularly 
curved, widest at the middle and tapering behind. The 
whole upper surface is very smooth and shining, finely punc- 
tured, as in C. pulchellus, less strongly than in C. formosus. 
The antenne are not very slender, but all the joints preceding 
the club are a little elongate, the 8rd not as long as the 4th
