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 punctures in the bottom of the striae there is a 

 row of from six to ten small punctures along the inner margin 

 of the 3rd and 5th striae, 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 punctuation along the sides of the basal segments of the 

 abdomen. Legs testaceous. 



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

 an Epomis, and has also some approach to its generic charac- 

 ters. The palpi are rather more securiform than in most of the 

 Chlaenii ; it has the foveae on the mentum, which are suggested 

 by Prof. Lacordaire as possibly a good character by which to 

 distinguish Epomis from Chlcenius* ; but the palpi are not more 

 securiform than those of some other Chlanii, and it wants the 

 yellow margin of the elytra. 



5. Ch. Fairmairei, mihi. 



Capite virescenti et thorace viridi, nitidis ; thorace subquadrato, 

 sparsim punctato ; elytris obovatis, subconvexis, nigris, punc- 

 tato-striatis, interstitiis impunctatis ; subtus niger; pedibus 

 rufescentibus. 



Long. 8| lin., lat. 31 lin. 



Head virescent with feeble violet reflexions, impunctate or 

 nearly so, faintly wrinkled here and there, chiefly transversely; 

 the usual anterior foveae effaced, or only visible in particular 

 lights; clypeus virescent, narrowest in front, slightly emargi- 

 nate, with a puncture near each corner before and behind ; 

 labrum distinctly emarginate ; antennae piceous, basal joints 



* I fear this character must be renounced as of generic value in this 

 group, as I find several species, which cannot otherwise be separated from 

 Chlcenius, possessing it, while in others it exists in a greater or less degree. 

 I have observed, however, that wherever it is present in a marked degree, 

 the species have the general aspect of Epomis, though they may not have 

 the yellow margins on the elytra, as for instance, the present and several 

 species, from Hong Kong and the East.
