Enilomychid Cohnptera of Tndo-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. westivoodi and alboguitaius, 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. 



• Aiicylopus melanocephalus, Oliv. Although M. Vitalis has 

 only found a single specimen, this is probably the commonest 

 of all the Endomychidic, found almost all over the Old World.

Niger, nitidus, elytris violaceis, utroque maculis magnis duabus 

 flavis ornato, prima humerali aliaque subapicali, his maculis

 convexus, pronoto subtiliter irregtilariter punctulato, lateribns 

 leviter bisinuatis, angiilis productis, anticis baud acutis, posticis 

 acutis, foveis basalibus subtilibua ; elytris paulo fortius punctatis, 

 humeris modiee prominentibus, lateribus leviter arcuatiB, apicibua 

 paulo attenuatis ; autennis baud gracilibus, clava lata.

Ixuo-CiiiNA : Upper Mekong R., Nam Long (/?. Vitalis 

 de Salvazu, April). 



Only one specimen of the species has been found. 



Tbe 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 piomiiient and the sides gently and regularly 

 curved, wide&t at the middle aud tapering behind. The 

 whole upper surface is very smooth and shining, finely punc- 

 tured, as in C. pulclielliis^ less strongly than in C. formosus. 

 Tlie antenn.e are not very slender, bnt all the joints preceding 

 the clul) are a little elongate, the 3rd not as long as the 4lh
