﻿NEW SPECIES OF COLEOPTERA FROM CHINA. 85 



in several tribes, and divided amongst their respective genera ; 

 thus, Chalcolema has the head and antennae of a Megascelis, 

 a thorax peculiar to itself on account of a distinct lateral margin 

 and its general shape, while the proportionate length of the 

 abdominal segments resemble those of the Crioceridcs, as well as 

 its general elongate shape and narrow elytral epipleurae ; the 

 appendiculate claws, however, again separate it from the last- 

 named tribe. 



Type, Chalcolema foveicollis. 



Chalcolema foveicollis, n. sp. (Plate I. fig. 1). 



Black ; the head, thorax, and legs fulvous ; elytra metallic dark blue ; 

 thorax remotely punctured, deeply foveolate at the sides ; ^elytra closely and 

 strongly punctured, finely pubescent. Length, 4| lines. 



Head swollen at the vertex, strongly but remotely punctured, with a 

 central longitudinal groove ; clypeus wedge-shaped, deflexed, its surface con- 

 cave, its anterior margin emarginate, obliquely angulate at the sides ; labrum 

 transverse, deeply concave at its anterior margin ; mandibles very robust 

 and thickened ; palpi filiform, black, the terminal joint longer than broad, 

 pointed ; antennae more than half the length of the body, black, the basal 

 joint obscure fulvous below, short and thickened, the second slightly shorter 

 and less stout, the others elongate and slender, nearly equal in length, 

 the terminal joint with a short and pointed appendage ; thorax slightly 

 broader than long, the base somewhat narrower, the anterior angles tubercu- 

 liform, the surface very remotely but distincly punctured, fulvous, shining, 

 with a deep longitudinal fovea near the lateral margin, and a larger and more 

 rounded one at each side near the base ; scutellum black, shining ; elytra 

 elongate, slightly constricted at the middle, the shoulders prominent and 

 acute, bounded inwards by a deep longitudinal depression, the disc closely 

 impressed with smaller and larger punctures, the interstices somewhat 

 transversely rugose (especially near the suture), and sparingly clothed with 

 short pubescence ; underside black, shining, the coxae, legs, and the pros- 

 ternum fulvous ; tibiae clothed with yellowish pubescence. 



Lema chinensis, n. sp. 



Black ; the base of the head, thorax and elytra fulvous ; thorax impunc- 

 tate ; elytra with a sutural depression, strongly punctate-striate ; abdomen 

 and the middle of the breast, fulvous. Length, 2 — 2h lines. 



Head black, the base and two rather strongly raised tubercles between 

 the eyes fulvous ; eyes deeply indented, the lateral grooves deep, the lower 

 portion of the face sparingly clothed with yellow pubescent ; antennae rather 

 short and robust, entirely black, the fourth joint slightly longer than the 

 third ; thorax not longer than broad, the sides rather deeply constricted, the 

 basal sulcation distinct, placed at some distance from the base, the anterior 

 angles with a minute tubercle bearing a single hair, the surface impunctate ■ 

 scutellum fulvous ; elytra with a distinct sutural depression below the base' 

 regularly and rather deeply punctate-striate, the interstices at the sides and 

 at the apex, costate ; underside clothed with fine yellow pubescence. 



The entirely black antennae, colour of the head and the two 

 tubercles of the latter, as well as the fulvous abdomen, separate 

 L. chinensis from its Asiatic congeners ; the amount of fulvous of 

 the breast is somewhat variable. The species seems allied to L. 

 russula, Bohem. (bohemani, Clark), but differs in its coloration. 



A few specimens.
