40 LAMELLICOENIA. 



et pedes viridi-asnei vel cuprei ; capite remote punctulato, clypeo vix depresso, integro ; thorace versus 

 apicem subdilatato, creberrime sed discrete ocellato-punctato, asqualiter convexo, prope scutellum paullo 

 depresso : elytris moniliato-striatis, interstitiis nigro setulosis ; corpore subtus fere laevi, abdomine apice 

 femoribusque valde punctatis ; mesosterno medio longitudinaliter depresso. 



cJ . Tibiae anticae subtus unidentatae ; tibiae posticae intus paullulum flexuosae, 8-tuberculatae, apice intus medio- 

 criter productae, ecalcaratae ; abdomine basi lato concavo. 



$ . Tibiae anticae subtus inermes, posticae simplices ; abdomine convexo.

Of similar large size and elongate-oblong form to E. claudicans ; but differing from 

 that species by its opaque velvety upper surface, and rich coppery or brassy-green 

 subsericeous under surface, with the legs wholly also metallic. The secondary sexual 

 characters as above indicated are also entirely different. As in E. claudicans, the 

 marginal carina of the elytra, formed by the upper edge of the epipleurse, is not 

 elevated as in the species allied to E. planus ; and the humeral carina is very short and 

 obtuse, and not continued beyond the point where the epipleural margin curves upward 

 from the base.

cJ. Tibiae anticae intus multi-denticulatae, subtus sicut in $ inermes; metasternum apice tuberculo'conico; tibiae 

 posticae valde arcuatae, intus multi-tuberculatae. 



Most examples are uniform opaque, sooty black above, with brassy-black legs ; but 

 in others the elytra are more or less variegated with dull red. In both sexes the 

 metasternum has a rounded fovea in the centre, and the hind femora a strong spine 

 beneath towards the apex. The humeral carina of the elytra is prolonged to three- 

 fourths of the elytral length, and overtops the lateral carina, i. e. the upper edge of the 

 epipleura, except towards the apex. 



We figure a specimen from Juquila.

Compared by Kirsch with E. mexicanus^ but much more nearly allied to E. planus^ 

 Dalm., having, like that species, a very short humeral carina, and an acute strongly 

 elevated epipleural carina. From E. planus it differs in the male only having a spine 

 underneath the hind femora (in E. planus the spine exists in both sexes) ; and in the
