Herr C. Fclsclie has received a series of specimens, of 

 which lie has kiiully presented a pair to the British Mnseuni. 

 The species is smaller than those just described and diflers 

 from all iiitlierto known in having only three teeth to the 

 front tibiic. It is very smooth and shining above, with 

 the elytra and the pygidium very strongly punctured. The 

 mule lias a short but slender horn on the head and the 

 pronotum is horizontally produced into a short broad lobe, 

 sharply pointed on each side. The lateral margins also bear 

 a blunt prominence on each side a little behind the front 

 angles. 



Pseudohomonyx crassus, sp. n. (PI. V. fig. 6.) 



Niger, nitidus, elongatus, pectore abdominisque latcribus rufo- 

 hirsutis, capite sat aequaliter transversim plicato, clypeo antice 

 attenuate, truncato ; prothoracis lateribus tenuiter punctatis, 

 antice paulo fortius, anguste margiuatis ; scutollo vix punctate ; 

 elytris grosso punctato-striatis, stria secunda antice, 4' et 5* 

 postice, abbreviatis, apicibus irregulariter grosae punctatis ; 

 pygidio antice punctate, postice lajvi : 



(S , protlioraco antice sat late impresso, margine antico acute 

 tuberculato ; pygidio antice confuse anuulato-punctato : 



5 , prothorace omnino la3vi ; pygidio lateraliter grosse, medio 

 subtiiiter, punctate. 



Long. 21-24 mm.; lat. max. 11'5-13 mm.

This is a species very closely related to P. borneensis, 

 Arrow, but rather larger, with finer lateral margins to the 

 pronotum and the elytral strise coarse but less deep. The 

 pygidium is also much less strongly sculptured in both sexes, 

 Avith its apical half smooth and shining. The male has a 

 much larger and deeper impression on the pronotum, about 

 as wide as it is long, and a sharp conspicuous tubercle in 

 front of it. 



Labuan I. was erroneously included as a locality for 

 P. borneensis. 



Prof. Kolbe has proposed the name Heteroligus for various 

 species formerly included in the genus Heteronychus, but 

 which seem to me to include three well-marked generic types. 

 As in the case of other genera created by him. Prof. Kolbe 

 has contented himself with a very casual and fragmentary 

 reference which affords no means of determining to which 

 of these types his name ought to be applied. I therefore 

 select as the type of Heteroligus the first enumerated and
