﻿NEW SPECIES OP COLEOPTERA FROM CHINA. 89 



of punctures with more finely punctured interstices, while these 

 latter in the female are as deeply punctured as the rest of the 

 punctures ; the flavous colour of the elytra forms three spots on 

 each, placed one at the base, the second at the middle, and the 

 third at the apex; the lateral black stripe is rounded in front of 

 each of the flavous spots. 

 Several specimens. 



Cryptocephalus discoidalis, n. sp. 



Black ; the head (the vertex excepted), the sides of the thorax and the 

 anterior femora fulvous ; thorax impunctate ; elytra violaceous-blue, strongly 

 punctate-striate. Length, 1J line. 



Head impunctate, obscure fulvous, the vertex piceous ; labrum black ; 

 the lower five joints of the antennae fulvous, the basal joint piceous above, 

 the others black ; thorax short, nearly three times broader than long, the 

 lateral margins very slightly rounded, the angles acute, the surface smooth 

 and shining, fulvous with a discoidal lozenge-shaped black spot from the 

 base to the apex ; scutellum raised, black ; elytra dark blue, regularly 

 punctate-striate, the punctures diminishing in depth towards the apex, the 

 interstices somewhat rugose at the sides, the shoulders prominent, sub- 

 tuberculiform ; pygidium and under side black ; anterior femora and the 

 prosternum fulvous, the latter ending into a sharp point at each side. 



The above description is that of the female insect ; a single 

 male now before me has a rather deep longitudinal and punctured 

 depression at the vertex, and the thorax is nearly entirely black, 

 the sides being broadly and the anterior margin narrowly flavous ; 

 the punctuation of the elytra is rather more strongly impressed. 

 This small Cryptocephalus resembles certain varieties of C. albo- 

 scutellatus, Suffr., but differs in the flavous anterior femora, the 

 stronger elytral punctuation, and in the shape of the pro- 

 sternum. 



DlORYCTUS NIGRIPENNIS, n. Sp. 



Fulvous ; the terminal joints of the antennie piceous ; head finely punc- 

 tured ; thorax impunctate ; elytra black, finely punctate-striate. Length, 

 2 fines. 



Broadly subquadrate, robust ; the head rather closely and very finely 

 punctured, fulvous ; eyes broadly and subangulate emarginate ; antennge 

 short, the lower five joints fulvous, the others fuscous slightly widened ; 

 thorax strongly narrowed in front, the sides evenly rounded and very nar- 

 rowly margined, the posterior angles acute, the posterior margin slightly 

 sinuate and produced into a point at the middle, the surface not visibly 

 punctured, fulvous, shining, the extreme basal margin black ; scutellum not 

 visible ; elytra broadly subquadrate, their apex broadly rounded, the basal 

 lobe obliquely produced at the middle, the disc with ten rows of fine punctures, 

 black, the interstices flat and impunctate ; under side and legs fulvous ; pro- 

 sternum much broader than long ; the anterior margin produced into a 

 distinct tooth at the middle, the posterior margin concave at each side. 



Hab. China (coll. Jacoby). 



A single specimen of this proportionately large-sized species 

 is contained in my collection from China without precise 

 locality.
