6 THE ENTOMOLOGIST. 



Chlamys geniculata, n. sp. 



Black ; the antennae and tarsi fulvous ; thorax with four longitudinal 

 ridges in front, the base raised, broadly channelled, interstices closely 

 punctured; elytra with two longitudinal ridges joined below the middle, the 

 apex with two short ridges, interstices punctured like the thorax. Length 

 li line. 



Subcylindrical and parallel, black ; the head flat, strongly and rather 

 closely punctured, the lower portion rugose; the eyes deeply notched; 

 labrum and palpi fulvous ; antennae with the apical five joints transverse, 

 entirely fulvous, the third and fourth joints slender, equal; thorax strongly 

 raised posteriorly into a hump, the hinder portion of which is deeply divided 

 and transversely wrinkled, the top of each division having a strongly-curved 

 S-shaped ridge, which extends downwards at each side towards the front, 

 the latter also furnished with two ridges at the middle, running towards the 

 anterior margin; a tubercle is also placed near the lateral margins, the 

 entire interstices strongly punctured and wrinkled ; scutellum strongly 

 transverse; elytra sculptured like the thorax, the suture finely dentate; a 

 strongly-raised ridge extends from the middle of the base below the 

 middle and, curving round, runs upward again to the base near the suture ; 

 the sides are furnished with three short transverse ridges at nearly equal 

 distances, and the apex has another very short slightly curved ridge near 

 the suture, as well as a tubercle near the lateral margin ; deep punctures 

 and wrinkles fill up all the interstices ; legs rather slender, the knees and 

 the tarsi fulvous; under side closely and htrongly punctured; presternum 

 very broad anteriorly, terminating into a narrow acute ridge, closely 

 punctured. 



The species may be distinguished principally by the colour of 

 the antennae, knees and tarsi, and by the very conspicuous ridge 

 of the elytra, which at its apex turns abruptly round, running 

 upwards again near the suture. 



CoLASPOSOMA ObERTHURI, B. Sp. 



Brownish cupreous; antennae black, the basal joints fulvous; head 

 rugose; thorax closely and strongly punctured, the sides rugosely punc- 

 tate; elytra strongly punctured in closely-arranged rows, the sides trans- 

 versely rugose. Length, 2 — 2^- lines. 



Of bronze colour; the head closely rugose-punctate throughout, the 

 vertex strigose, the strigae extending to the middle of the head ; antennae 

 extending a little beyond the base of the thorax, black, the lower six joints 

 fulvous, the third joint longer than the fourth ; thorax rather short, more 

 than twice as broad as long, the sides evenly rounded, the surface very 

 closely and strongly punctured, the interstices at the sides rugose or 

 wrinkled, often confluent; scutellum not broader than long, with some 

 distinct punctures; el)'tra scarcely perceptibly depressed below the base, as 

 strongly punctured as the thorax, the punctures arranged in rather close 

 and irregular rows, of which three near the suture towards the apex are 

 more regular than the rest, the punctures below the shoulders and at the 

 sides larger and closer placed, the interstices at the same places but 

 slightly rugose ; legs coloured like the upper side. 



From the many other Eastern species of the genus the 

 present one may be known principally by the very closely punc-
