TRAPEZIDISTES RITSEMAE. 125 



Sumatra: Highlands of Palembang (Scient. Sum. Exp.). 

 A single specimen. — Languria spec. 5, in » Midden- 

 Sumatra, Coleoptera, p. 184." 



Among the beetles in the collection there are a number 

 of specimens of the variable leiralanguria splendens Wied, 

 (= elongata Fabr., pyramidata Mac L. etc.). 



One of the varieties from Taudjong Morawa (Serdang : East 

 Sumatra) seems fairly constant and , were it not connected 

 with the type forms by various gradations , might be accoun- 

 ted a separate species; it is robust, with the elytra broad 

 at shoulders which are strongly marked , and gradually 

 narrowed to apex; the thorax is of a golden brassy colour, 

 and the elytra brassy with a slight greenish reflection; 

 the legs are in part at least reddish. For this variety I 

 propose the name of var. a ene a. I should be inclined to 

 consider it a new species, were it not for the fact that one 

 or two specimens show a distinct tendency in the colou- 

 ring of the thorax to revert to the pyramidata form. 



There is hardly any species, among the Coleoptera that 

 varies so much as this in size , shape and colour. In the 

 collection before me there is a small quite parallel specimen 

 about 7'/2 mm. long, and several others about 18 mm. 

 long with the breadth varying from 1^/4 or 2 mm. at apex 

 of elytra to 4 mm. at their base.
