PmLANTHAXIA CYANESCENS, new species. 



Oblong-oval, head pronotum and elytra uniformly cyaneous with 

 a slight violaceous tinge, glabrous; beneath piceous with a slight 

 greenish tinge and sparsely clothed with fine, recumbent, cinereous 

 pubescence. 



Head strongly convex, transversely concave between the antennae; 

 surface densely, strongly reticulate, the reticulation forming a net- 

 work of small, irregular, sunken areas; eyes not projecting beyond 

 the pronotum on either side ; epistoma wide, truncate in front. Pro- 

 notum convex, nearly two times as wide as long, slightly narrower 

 in front than behind ; sides feebly arcuate and sinuate near posterior 

 angles, which are rather obtuse; anterior margin arcuately emargi- 

 nate with a feebly rounded median lobe ; base truncate ; surface with 

 a very feeble broad impression on each side near posterior angles, 

 punctuation similar to that on the head, but becoming finer on the 

 disk. Scutellum cordif orm, truncate in front, wider than long ; sur- 

 face finely granulated and strongly concave. Elytra slightly wider 

 than pronotum at base ; sides sinuate behind the humeri and feebly 

 diverging to the apical third, then obliquely attenuate to the tips, 

 which are separately, narrowly rounded; lateral margin finely ser 

 rate; each elytron with a 'deep transverse groove situated a little 

 below the base at the outer margin, the space between the base and 

 groove being raised and rounded; humeri prominent; surface deeply 

 and regularly striate, the striae not quite reaching to the apex and 

 somewhat confused at the scutellar region; intervals flat, densely, 

 transversely rugose, rather densely, finely punctate, and becoming 

 scabrous at the apex. Abdomen beneath finely and rather densely 

 ocellute-punctate, becoming somewhat longitudinally rugose on the 

 last segment, which is rather acutely rounded at apex; posterior 

 coxae with the posterior margin truncate; prosternum and middle 

 of body strongly and densely scabrous ; femora and tibiae finely but 

 not densely rugose. 



Length, 7.5 mm. ; width, 3.5 mm.
