1 66 MEMOIRS ON THE COLEOPTERA 



again exactly as in Harpalus; it also resembles that genus, and 

 departs from the Selenophorini, in the short basal joint of the hind 

 tarsi. The labial palpi are as in Harpalus. In fact the only strong 

 evidences of affinity in the direction of Selenophorus are the triple 

 series of elytral punctures, uniformly punctate abdomen, and the 

 Discoderus-like facies of the body; as however the triple series are 

 unknown in Harpalus and allied genera, it would seem most fitting 

 to place the genus here and not in the Harpalini. This genus is 

 the best example known to me of the almost interminable cross 

 affinities, which render a satisfactory subdivision into tribes and 

 genera so difficult and uncertain throughout the Harpalinae. The 

 type species may be described as follows : 



Body oblong-elongate, strongly convex, shining, the elytra ( 9 ) slightly 

 alutaceous; color pale and uniform testaceous throughout ;. head 

 nearly two-thirds as wide as the prothorax, only feebly constricted 

 at base, the eyes moderate, the foveae minute and perforato-puncti- 

 form; mandibles short, largely hidden when closed, the antennae 

 moderately stout, as long as the thoracic width, or shorter (9); 

 prothorax one-half wider than long, slightly widest before the middle, 

 the sides almost evenly and broadly arcuate; apex feebly and 

 sinuously, the base rectilinearly, truncate, equal in width; basal 

 angles broadly rounded; surface impunctate, steeply sloping at the 

 sides to the rather wide subdeplanate reflexed margin throughout 

 the length, the flattened margin curving inward at base, smooth but 

 having four long erect setae arising from coarse punctures; stria 

 extremely fine, the foveae small, sublinear and deeply impressed, 

 wholly impunctate; elytra oblong, parallel, with feebly arcuate sides 

 and obtuse apex, equal in width to the prothorax and fully one-half 

 longer than wide, the humeii minutely denticulate, the sinus broad 

 and extremely feeble, the apices (cf) rounded, or ( 9 ) with acutely 

 spiniform sutural angles, the denticles bordered externally by a short 

 deep sinus, this structure being somewhat as in Harpalus leicisi; 

 striae rather strong, the scutellar very moderate, the intervals neaily 

 flat, slightly convex suturally, nowhere punctulate, the marginal line 

 of foveae not medially interrupted; punctures of the three lines coarse, 

 widely spaced and somewhat erratic, not always closely connected 

 with the striae, this being especially the case with the middle series; 

 abdomen uniformly, finely and sparsely punctulate, the punctures 

 bearing erect and rather stiff short hairs, the apex with four setae 

 in both sexes; legs rather stout, the hind tarsi filiform, moderately 

 stout, the three basal joints decreasing uniformly and slowly in 

 length, the first two-thirds as long as the fifth, the claws rather long, 

 slender and not very arcuate; bristling hairs of the middle and hind 

 tibiae very numerous; tibial spurs short and stout, the single spur of 

 the anterior with a distinct angulation at one side near the base.
