Mr. A. Murray on Coleoj^tera from Old Calabar, 131 



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

 over the interstices ; a few larger impressions on the marginal 

 spaces towards the apex; slightly pubescent towards the sides j 

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

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

 which is coarsely punctured. Legs testaceous. 



Readily distinguished from Chlcmius glabratus, Dej., by the 

 elytra being black and showing scarcely any indication of vires- 

 cence, while in glahratus they are green and metallic. 



4. Ch. immunituSj mihi. 



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

 nis,palpispedibusquetestaceis; thorace angustato, sparsissime 

 punctato ; elytris elongatis, depressis, fere glabris, punctato- 

 striatis, interstitiis impunctatis. 



Long. 7 1 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 emargi- 

 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 elon- 

 gate-impunctate fovea placed on each side somewhat obliquely 

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

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

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

 tate ; besides the^unctures in the bottom of the strise there is a 

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

 3rd and 5th strise, 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 emarginate. Under side polished, 

 prosternum and breast faintly and very sparsely punctured; 

 metasternum 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'f it has the foveje on the mentum, which are
