pjnlarly (or sometimes with a tendency to a linear arrangement) 

 over the interstices; a iaw hirgcr impressions on the marginal 

 spaces towards the apex; shghtly pubescent towards the sides; 

 the margins and the edges of the suture transhicent-rufescent. 

 Under side shining, and scarcely punctate, except on the breast, 

 which is coarsely pinicturcd. Legs testaceous. 



Readily distinguished i'rom ChUen'ms ylahrntus, Dej., by the 

 elytra being black and showing scarcely any indication of vires- 

 ccncc, while in glubratus they are green and metallic. 



4. Ch. immunitus, mihi. 



Elongatus, politus, nitidus, supra ianthinus, subtus nigcr ; anten- 

 nis,palpispedibusquctestaceis; thorace angustato, sparsissime 

 punctato; clytris clongatis, depressis, fcrc glabris, punctato- 

 striatis, intcrstitiis impunctatis. 



Long. 7'-\ lin., lat. 3 lin. 



Elongate, polished, shining, above of a rich violet-blue, below 

 black ; labrum and mandibles ferruginous ; antennse, palpi and 

 legs testaceous. Head smooth and impunctate, except a few 

 scattered punctures running across between the posterior angles 

 of the eyes, and one or two larger punctures before these, along- 

 side the eyes and front of the head; labrum scarcely cmargi- 

 nate. Thorax narrow, with a few distinct punctures scattered 

 very sparingly here and there over the surface, some of them 

 disposed in something like a row on each side of the dorsal line, 

 which is distinct, but reaches neither to the front nor base; 

 margined, a few punctures along the margin ; a very deep clon- 

 gatc-impunctate fovea ])laccd on each side somewhat obliquely 

 near the posterior angles, which arc obtuse, but scarcely rounded. 

 Scutellum large,black, and impunctate. Elytra glabrous, shining, 

 elongate, depressed, deeply punctate-striate, interstices impunc- 

 tate ; besides the punctures in the bottom of the stria there is a 

 row of six or ten small punctures along the inner margin of the 

 3rd and 5th strire, and also along the interstice next the marginal 

 space, which is granulose, with a row of round, shallow pits with 

 an elevation in the centre ; the granulose space becomes widest at 

 the apex, which is very slightly emarginatc. Under side polished, 

 prosternum and breast faintly and very sparsely punctured; 

 mctastcrnnm more closely punctured ; traces of coarse punctua- 

 tion along the sides of the basal segments of abdomen. Legs 

 testaceous. 



This species, in its general outline, has much the general 

 aspect of an Epomis, and has also some approach to its generic 

 characters. The palpi are rather more securiform than in most 

 of the Chlcenii; it has the fovea) ou the mcutum, which are
