ZOOLOGISCHE MEDEDEELINGEN — DEEL VI. 



chitin; the prothorax is divided into two parts by a curve between the 

 two lateral spines on the tubercles. The oral part brownish red, speckled 

 with black; the distal part more rose, reddish gray with more redbrown 

 to the distal margin. On the pronotum a trace of a median suture and 

 a fold, parallel with the distal margin, are visible. Ventrally the pros- 

 ternum, acutely produced between the large coxae of the forelegs, is 

 hardly visible. 



Scutellum: small, rounded distally, rose, with a very small black 

 line near to the prothorax. 



Elytra: beautiful silk-like auburn, with rose outermargins. The 

 rose margin very narrow along the basal two-thirds of the elytra, thence 

 broader and ending narrowly at the tips. Shoulders rounded; sides (seen 

 dorsally) parallel, converging to the end and finishing subacutely. Seen 

 laterally, there is a bend in the elytra between middle- and hiudlegs. 



Underside of the body light grayish redbrown with some violet 

 gloss. The mesosternum, very narrow between the coxae of the middle 

 legs, has the shape of a V with two lateral lobes. The fine abdominal 

 segments (sternites) are darker coloured than the sterna. The anal ster- 

 nite triangular, broad at the base with the little incised tubular end 

 protruding from the elytra. 



Legs: grayish redbrown with darker spots on femora and tibiae; 

 the ends of the joints rose. In the tibiae of the middlelegs a character- 

 istic incision, absent in the other tibiae.
