tate. Elytra gradualy narrowing from base to apex ; strise deeply impressed ; 

 intervals nearly flat, granulate-rugose. Metsternum rather coarsely and 

 densely punctate. Abdomen more sparsely and finely punctate; first joint of 

 hind tarsi very nearly as long as the following together. Length 6 mm. 



Southern Pines, N. C. (A. H. Manee). 



A neat little species, which was sent me several years ago, col- 

 lected June 15, 1908. It resembles somewhat fully colored specimens 

 of riifilabris in form and coloration but has a differently formed third 

 antennal joint, a much longer first joint of hind tarsi and hind angles 

 of prothorax unicarinate. 



Diplostethus (Ludius) opacicollis new species. 



Dark castaneous, underside, legs, antenna and palpi paler, above and 

 below rather sparsely clothed with short fulvo-cinereous pubescence. Head 

 coarsely and closely punctate ; antennae extending to a little below the elytral 

 humeri, strongly serrate, joints three a little longer than second, the two 

 together nearly as long as the fourth joint, eleventh joint slightly longer than 

 the tenth and feebly appendiculate. Prothorax convex, slightly broader at 

 base than long, sides feebly converging to about one third from apex and then 

 arcuately converging to apex ; surface alutaceous, coarsely and closely punc- 

 tate ; hind angles strongly, obliquely carinate. Elytra about two and one half 

 times as long as the prothorax and rather strongly narrowing to apex, sutural 

 angles feebly rounded ; surface punctate-striate ; intervals flat, moderately 

 coarsely punctate, the punctures not very closely placed and not smaller than 

 those of the striae, surface at base somewhat rugose. Prosternum shining 

 and coarsely and moderately closely punctate ; side pieces dull with smaller 

 punctures, intercoxal process a little behind the coxae suddenly and per- 

 pendicularly declivous, intercoxal portion of mesosternum as in te.vaiius. 

 Metasternum coarsely and not closely punctate. Abdomen more finely and 

 sparsely punctate than the metasternum. Length 20 mm. 



Nogales (type) (Nunnenmacher) and Huachuca Mts., Ariz. 

 (Schaeffer). 



This species is related to tcxamis and peninsnlaris. From the 

 former it differs in the form of intercoxal process of prosternum and 

 from peninsnlaris in having a dull, more densely punctate prothorax 

 and the declivous portion of the intercoxal process of prosternum 

 rounded in front above, which part forms in peninsuaris a small and 

 rather sharp tooth. It seems to be also very close to the Mexican 

 sctosus but that species has apparently a longer fourth antennal joint 

 and denser pubescence on upper and under surface.
