TH05. L. CASEY. 



BRADICELLIJS. 



B. llicidlis 11. sp. — Form ratlu'i- elongated, moderately convex; sides 

 nearly parallel ; glabrous above. Color above deep piceoiis-black, beneath 

 black, legs fulvo-testaceous, antennae and oral organs reddisli-piceous. 

 Head moderate, slender, longer than wide, very convex ; supra-orbital setae 

 stout, very slightly behind the middle of the eye ; eyes almost exactly circu- 

 lar, moderately convex ; antennae as long as head and prothorax together, 

 reddish-testaceous throughout, last seven joints compressed, third joint more 

 than twice as long as the second ; emargination of meiitum broad, tooth well- 

 developed, very slightly rounded at the tip ; dental setae approximate, long ; 

 on the sub-mentum, at a distance from each extremity equal to one-fourtli 

 its width, there is a pair of long stout setae, also a single short seta at each 

 lateral anterior angle. Prothorax widest Just in advance of the middle, 

 where it is one-third wider than long ; anterior margin very slightly shorter 

 than the posterior, broadly and feebly emarginate, posterior margin broadly, 

 feebly, and slightly irregularly arcuate ; anterior and posterior angles broadly 

 rounded ; sides rather strongly arcuate, most strongly so in advance of the 

 middle ; disk rather feebly convex, large ; basal impressions feeble, finely 

 and feebly punctulate ; median line narrowly impressed, distinct ; surface 

 polished, paler at the edges, margined narrowly throughout its circumfer- 

 ence. Elytra at base slightly wider than the contiguous pronotum ; sides 

 strongly divergent and arcuate for a short distance from the humeri, then 

 parallel and nearly straight for two-thirds the length posteriorly ; disk 

 moderately convex, obtusely rounded behind ; striae narrowly impressed, 

 intervals flat, polished, and minutely reticulated ; transverse basal groove 

 strongly bisinuate, making with the acute lateral edges at the humeri, very 

 acute angles ; .each elytron has a single puncture near the second stria and 

 at two-thirds the length posteriorly. First four joints of the anterior and 

 middle tarsi strongly and nearly equally dilated, densely spongy-pubescent 

 beneath ; first joint of the posterior tarsi very slightly longer than the second. 

 Length 6.0 mm. 



Arizona (Morrison). 



Tliis species is remarkable amongst its congeners, for the very 

 strong dilatation of the middle tarsal joints in the male ; the setae on 

 the sub-mentum are also somewhat singular. 



HARPALUS. 



II. opaciIS 11. sp. — Form and size nearly as in rujiiiianus. Body nearly 

 opaque, black. Head rather broad ; labrum short, broad, feebly, and 

 roundly emarginate anteriorly ; antennae scarcely as long as width of pro- 

 thorax, first joint nearly as long as the second and third together, rufo-testa- 

 ceous, remaining joints robust and thickly clothed with short piceous setae, 

 last joint perceptibly compressed ; last joint of maxillary palpi much darker 

 toward base. Prothorax nearly one-half as wide again as long ; sides rather 

 feebly arcuate, more so anteriorly, apex narrower than base; basal angles 

 rounded, lateral border narrow but. verv strong ; surface feeblv convex.
