AMERICAN COLEOPTERA. 87 



cinereous pubescence, the elytra having in addition sparsely placed, 

 short, black, erect hairs. 



Malachius (Hapalorhinus) biguttulus, n. sp. — Body black with strong fene- 

 ous or bluish tinge. Head moderately broad, shining, sparsely punctured, 

 aeneous. Thorax broader than long, moderately convex, shining, very sparsely 

 and finely punctured: sides strongly rounded, margin moderately reflexed at 

 base. Elytra slightly broader than thorax, -seneous, moderately shining, scab- 

 rous, and with a yellow spot on each at suture near apex. Body beneath seneous 

 black. Male antennae serrate, black ; apex of elytra slightly impressed and 

 sinuous at margin. Length .14 inch ; 3.i mm. 



The entire surface of body is sparsely clothed with cinereous pubes- 

 cence, that of the elytra being longer and more nearly erect. 



A single specimen from Fort Tejon, Cal., and may easily be distin- 

 guished from any of our species o^ Malachius of the group Hapalor- 

 hinus by the characters above given. 



CHAEIESSA, Perty. 



C. elegans, n. sp. 



Similar in form to C. pilosa (Forst.), Lee., but broaderaud differing 

 as follows : 



Subopaque, pale red, elytra bluish black. Head coarsely punctured and 

 with semi-erect hairs; antennae black with basal joint onl^' red. Thorax 

 broader than long, truncate in front sides strongly rounded and slightly narrower 

 behind, base broadly rounded, with margin reflexed and black ; surface densely 

 and coarsely punctured and clothed with sub-erect hairs. Scutellum and 

 elytra bluish-black, the latter coarsely and densely punctured and scabrous, 

 the punctures coarse and less dense at the scutellar region, and with the 

 humeral region somewhat smoother, surface sparsely clothed with short, black, 

 sub-erect hairs. Body beneath and legs entirely pale red, and clothed with 

 pale sanguineous pubescence; tarsi, maxillary palpi and tip of mandibles black. 

 Length .46 inch; 1L5 mm. 



The only species with which this might be confounded at first sight 

 is C. dichroa, Lee, from which it differs in having the thorax densely 

 pnnctured, the elytra more densely punctured and not submctallic and 

 by the legs being entirely red. The basal margin of the thorax is 

 more distinctly reflexed than any other of our species and the reflexed 

 portion margined with black. The hairs clothing the head, thorax, 

 under surface and legs are pale sanguineous being of a different shade 

 of color from the surface on which they are placed. 



From San Joaquin County, California. A single specimen was 

 kindly placed in my cabinet by 3Ir. Wilhclm Jiilich of New 

 York.
