124 MEMOIRS ON THE COLEOPTERA 



a third longer than the femora, the tarsi two-thirds as long as the 

 tibiae. Length (cf) 7-5 mm.; width 2.8 mm. Arizona (probably 

 southern) socors n. sp. 



Body oblong-suboval, rather broader and less convex than in socors, 

 blackish-piceous to paler above, the elytra darker than the anterior 

 parts, red-brown beneath; surface very shining, the elytra subsimilar 

 in the sexes; head nearly as in socors but with rather less minute 

 foveae; prothorax similar throughout, except that the apex is more 

 deeply sinuate and with the apical angles much more narrowly 

 rounded and more anteriorly prominent; it is also relatively larger 

 in size; elytra not more than a third longer than wide, slightly wider 

 than the prothorax, parallel, with feebly arcuate sides, the humeri 

 much more strongly denticulate, the striae finer and less impressed, 

 the scutellar similarly long and generally free, the intervals much 

 less convex, the sutural angles strongly denticulate in both sexes; 

 accessory punctures few in number and widely dispersed; femora not 

 quite so short when compared with the tibiae. Length (cf 9 ) 6.5- 

 7.8 mm.; width 2.3-3.0 mm. New Mexico (Fort YVingate). Eight 

 examples. [H. ochropus Kirby?] desertus Lee. 



21 Body rather broadly oblong-suboval, notably small, rather convex, 

 strongly shining, blackish-piceous in color above and beneath; head 

 very moderate, with very prominent eyes, the foveae relatively 

 strong, perforato-punctiform; antennae obscure testaceous, coming 

 far from attaining the thoracic base; mentum tooth strong, with 

 the apex not acute but rounded; prothorax short, fully three-fifths 

 wider than long, the sides almost evenly and distinctly rounded, 

 only a little less so basally, the apex evidently but not deeply 

 sinuate, with well rounded angles and barely at all narrower than 

 the base, the latter subevenly transverse, finely margined, with 

 obtuse and broadly rounded angles ; surface almost evenly and broadly 

 convex, the reflexed margin moderately fine, almost even from apex 

 to base, the foveae small, short, linear, feebly impressed and very 

 indistinctly, sparsely punctulate; punctures elsewhere wanting, the 

 stria rather distinct but biabbreviated; elytra barely a third longer 

 than wide, only just visibly wider than the prothorax, the sides 

 feebly arcuate, the humeri not denticulate; striae fine, rather abrupt, 

 the scutellar short and oblique; intervals virtually flat, the dorsal 

 puncture completely obsolete, no vestige being discoverable on 

 either elytron in the type; hind tarsi barely two-thirds as long as the 

 tibiae; accessory punctures numerous, markedly fine and irregularly 

 distributed. Length (cf) 6.8 mm.; width 2.75 mm. Colorado 

 (Salida), Wickham curticornis n. sp. 



22 Body oblong, subparallel, compact, very convex, highly polished 

 throughout, rufo-piceous to nearly black, the legs and under surface 

 pale and testaceous, the upper surface, especially the elytra, more or 

 less strongly metallic green in lustre; head short, with prominent 

 eyes, the mentum with a short broad and obtuse tooth, the antennae 

 rather short, not quite as long as the thoracic width; prothorax three- 

 fifths wider than long, the sides subparallel, rounding and slightly 

 converging anteriorly, parallel and broadly, just visibly sinuate
