CRATIDUS Lee. 

 The three species of this genus may be distinguished as follows : — 



Posterior angles of the prothorax acute and prominent. 



Pubescence pale tawny yellow oscula ns 



Pubescence piceous-black f tiscipilosus 



Posterior angles rounded rotlllldicollis 



C. fliscipilosus n. sp. — Form robust, convex, shining, very densely 

 clothed throughout with fine, long, erect, brown-black hairs. Head moderate, 

 densely and rather coarsely punctate ; antennas rather long and robust, but 

 very feebly incrassate toward apex, third joint fully three times as long as 

 wide. Prothorax from two-fifths to one-half wider than long, convex, strongly 

 rounded at the sides, which are very strongly convergent near the base and 

 sinuate for a very short distance before the basal angles the latter being very 

 small but acute and prominent ; apical angles prominent acute dentiform and 

 everted ; surface coarsely, very deeply and densely punctate. Elytra about 

 two and one-half times as long as the prothorax, oval, obtusely rounded at 

 apex from above, convex, somewhat finely but densely and very deeply punc- 

 tate, with imperfectly defined, unimpressed rows of similar but coarser punc- 

 tures. Legs short and robust, clothed with similar long, dark pubescence. 

 Length 14.0-16.0 mm.; width 7.2-8.3 mm. 



Southern California. 



The pubescence is nearly similar in color to that of Amphidora 

 nigropilosa, but while in G. f tiscipilosus the hairs are all alike, the 

 pubescence is dual in composition in the species referred to, there 

 being a system of long blackish hairs which are erect, and another 

 system of shorter, more appressed and paler ones. 



This species belongs near osculans, but differs not onty in the 

 color of the pubescence, which is quite constant throughout the 

 series of four specimens before me, but in its greater density, also 

 in the much more robust and compact form of the body, the pro- 

 thorax being shorter, more transverse and more nearly equal in 

 width to the elytra. 



The hind tibia? of the male have a strongly developed acute 

 oblique tooth near apical third as in osculans. 



IPHTHIMUS Truqui. 



Our western forms, allied to serratus, may be distinguished as 

 follows : — 



Punctures of the elytral intervals coarse and deep. 



Pronotum coarsely, very densely punctate throughout, the punctures gener- 

 ally subcontinent toward the sides, general surface lustre opaque.
