16 ABIRUS FLAVOPILOSUS. 



colour , the five terminal joints moderately dilated , the 

 last four joints distinctly shorter than the preceeding one. 

 Thorax broader than long , subcylindrical , the sides slightly 

 but regularly rounded, the anterior angles acute and pro- 

 duced, surface very closely rugose- p unctate , covered like 

 the head with short golden yellow hairs. Scutellum 

 broadly ovate, finely punctured, glabrous. Elytra closely 

 transversely rugulose and wrinkled , the interstices only 

 punctured near the base and close to the suture , longitu- 

 dinally costate near the apex only , pubescent like the 

 thorax, the hairs short, stiff and of a shining yellow co- 

 lour. Underside and legs still more densely pubescent. 



Two specimens from Moeara Laboe (Sumatra-Expedition). 



Closely allied to A. puberulus Lefèv. but differing in 

 the colour of the antennae and tibiae and in the yellow 

 not white pubescence. The head also in the present insect 

 is devoid of any smooth space and tubercle. 



Abirus violaceus ^ n. sp. 



Elongate, subcylindrical, bluish black below, finely pu- 

 bescent. A-bove violaceous blue, shining. Sides of thorax 

 obsoletely angulate , surface deeply punctured. Elytra trans- 

 versely elevate-reticulate , punctate-striate near the suture. 

 — Length 4 lines. 



Head finely and closely punctured , with an obsolete 

 tubercle at the middle of the front. Antennae with the 

 last five joints moderately dilated, bluish, pubescent, the 

 basal joints blackish and shining. Thorax twice as broad 

 as long , the sides but slightly deflexed , lateral margin 

 very obsoletely biangulate , all the angles acute and pro- 

 duced; surface with an oblique depression at each side 

 near the base , closely and deeply punctured posteriorly , 

 the punctuation rather more finely anteriorly , the punct- 

 ures themselves of somewhat oblong shape. Scutellum about 

 as broad as long, impunctate. Elytra narrowed posteri-
