Black, rather broad, thickly clothed with cinereous hairs. Head 

 short, subquadratc, the vertex, adjoining the thorax, smooth and 

 shinini;-, the Irons llat, posteriorly punctulated, anteriorly di- 

 stinctly striated, the central strirc extending to the vertex ; ros- 

 trum short, about twice the length of the head, porrect, a little 

 bent, tiliforni, the apex smooth and shining ; eyes ciliated beneath. 

 Antenna} inserted a little behind the middle of the rostrum, the 

 first and second joint and sometimes the third dull rufous, the 

 clava oblong, acuminated, black and pilose. Thorax as broad as 

 long, subglobose, laterally dilated and rounded, convex above, 

 closely and deeply ]nuictured with a distinct dorsal channel more 

 or less abbreviated in front. Elytra obovate, very convex, pro- 

 foundly punctato-sulcatc, the interstices rather broad and liat, 

 transversely rugulose, blue, obscure green or gi'ccnish black. 

 Legs very long, black. ^ . (Length 1^ line.) 



]\Ir. Waterhousc forwarded a British insect to M. Schouherr, 

 which was returned with the name oi Ap. jmvidum of Gennar. I 

 possess a foreign specimen from M. Schonhen* which is labelled 

 " Ap. pavidutn, G. e Saxon. Schupp," and I have another speci- 

 men of Ap. pavidum from Dr. Germar. Mr. Curtis has likewise 

 a foreign example of Ap). pavidum from ]\L Sturm. It is very 

 satisfactory to find four eminent entomologists all concurring in 

 one opinion as to the identity of this species ; but it is a curious 

 fact, that the four insects in question are decidedly all males. 

 M. Chevrolat not having a duplicate specimen of Ap. plumbeum 

 of Schonherr, very liberally sent to me the type of that species 

 for my inspection ; this I find is also a male of Ap. pavidum of 

 Germar. Dr. Germar has sent me fom' insects with the name of 

 Ap. Ononis, which I have carefidly examined : the male agrees in 

 evcry^ character with the male of Ap. pavidum; the female differs 

 in ha\ing the rostrum longer, before the antennae shghtly atte- 

 nuated, glabrous and shining, the antcnnsc placed behind the mid- 

 dle of the rostrum ; these are only sexual dissimilarities, and are 

 common to many other species; in other characters the males 

 and females agree. The four insects under consideration have 

 the sculpture very similar, and approximate rather closely in fonn 

 to Ap. Ononis of Kirby, but they are sufficiently distinct from 

 that species. See notes on Ap. Ononis. 



The only British example of this species that I have seen is in
