LYROPAEUS RITSEMAE. iOl 



ribus , sub-compressis , thorace parvo , trapeziforrai , angu- 

 lis posticis acutis , disco opaco , subflavo , medio obsolete 

 cariuato ; scutello medio fusculo ; elytris aurantiacis , lineis 

 duabus elevatis . una humerali , altera subsuturali , ante api- 

 cem desinentibus. — Long. 10 millim. 



Head very small , even , eyes prominent , small , subglo- 

 bose; palpi (maxillary?) small with cylindrical apical joint, 

 acuminate at apex , antennae two ; thirds the length of 

 body , basal joint small , obliquely truncate , inner apical 

 angle acute , second joint minute not easily observed , third 

 joint half as long again as the fourth , the succeeding joints 

 gently narrowing towards the apex. The thorax has the 

 sides straight, considerably narrowed towards the front, 

 the front and base truncate, but both slightly sinuous and 

 produced. The scutellum is notched at its apex. The ely- 

 tra are ample but not so much expanded in proportion as 

 in L. falla.v; the punctuation is close, irregular and con- 

 fluent; they are even and firm in consistence, the humeral 

 carina is well pronounced. The abdomen is distinctly punc- 

 tured, it has eight distinct plates, the apical being small 

 and narrow, the sub-apical finely notched. 



One specimen, probably a male, from Lebong (Sum. Exp.). 



15. Lyropaeus Ritsemae^ sp. n. 



NigrO'fuscus, depressus, capite minuto, antennis lineari- 

 bus , subcompressis , thorace angulis posticis acutis , elytris 

 nigris, basi aurantiacis. — Long. lO'/g millim. 



Although this species is very closely allied to L. Wa- 

 terhousei, and may perhaps vary in colour, yet there are 

 permanent structural diff'erences. The thorax has much 

 more prominent acute hind angles , so that its sides are 

 concave , and it is black as is the scutellum. The elytra 

 have the humeral carina more prominent and extending 

 quite a third of the elytral length; they are also more 

 expanded from beneath the carina till near the apex.
