process not strongly constricted by the anterior coxal cavities and 

 broadly rounded or acuminate at apex. Posterior coxae strongly 

 dilated internally; anterior margin sinuate; posterior margin arcu- 

 ately emarginate and strongly attenuate to the lateral margin. Legs 

 rather robust, femora fusiform, the anterior and middle ones more 

 strongly swollen at middle than the posterior pair; tibiae straight 

 and cylindrical, the anterior pair spatulate at apex; tarsi rather 

 broad; first joint of posterior pair not longer than the following 

 joint. Abdomen with the suture between the first and second seg- 

 ments distinct; first segment flat, concave or longitudinally grooved; 

 last segment variable. Body elongate, oval, rather convex, always 

 acuminate or bifurcate at apex. 



This is not a very large genus, containing only about 40 described 

 species, and which are confined to the Palaearctic and Nearctic Re- 

 gions. The two species recorded in the present paper from the West 

 Indies are certainly not indigenous to these islands, but have been 

 introduced at various times through commerce. The two species can 

 be separated by the following characters. 



KEY TO THE SPECIES 



Pronotum and elytra very uueveu, the latter with distinct smooth elevated 

 spaces tuberculata Castelnau and Gory. 



Pronotum and elytra not distinctly uneven, the latter with only obsolete ele- 

 vated spaces divaricata (Say).

Female. — Form rather narrowly elongate, attenuate behind, and 

 moderately convex; above uniformly cupreous, sometimes with a 

 greenish tinge, and the reliefs smooth and more brownish-cupreous; 

 beneath more reddish-cupreous. 



Head feebly convex and very uneven; surface coarsely, densely 

 and deeply punctate, the punctures irregular in size, confluent and 

 forming a number of smooth elevated rugae, sparsely clothed with 

 short, inconspicuous hairs; epistoma broadly arcuately emarginate 

 in front; eyes oblong, about two times as long as wide, and feebly 

 converging above. Pronotum nearly two times as wide as long, 

 widest at the apical third, apex and base about equal in width ; sides 

 strongly obliquely expanded from apex to apical third, where they
