SUBFAMILY V. APIOXIX.K. 



75 



One specimen from Koscinsko county, Indiana ; .June 9. Close 

 to ptnirlimixHiii Smith from the Northwest, but differs in color, 

 in the almost total absence of pubescence, in the deep elytra! 

 stria? with their strong punctuation and in the very fine, almost 

 obsolete punctuation of the first and second ventrals. 



Fig. 38. Characters . of Apion. a, Thorax not sinuate before the basal 

 margin; b, thorax sinuate near basal margin; c, thorax widest before the base, 

 not sinuate behind; d, head and beak of emaciipcx; c, thorax of crassiim; f, 



same of dccoloratinn ; g, same of cuiaciipcs; h, head and beak of male of 



segnipcs. (After Fall.) 



GROUP III. 



The species of this group have the claws plainly, usually 

 strongly toothed at base (Fig. 37, k, I.) and the tibiae of male, at 

 least two pairs of them, with small spines at tip. In almost all 

 species the form is moderately robust, thorax more or less wider 

 than long, wider behind and with a basal fovea ; humeri well de- 

 veloped and the surface plainly pubescent. It is to this group 

 that all the older and better known species except segnipes and 

 decolfii'uhtiit belong. 



KEY TO EASTERN SPECIES OF GROUP III.* 



a. Thorax slender, its sides nearly parallel, its base but little wider than 



apex; front coxae of male with a conical tubercle at apex; surface 



bronzed. 85. COXALE. 



act. Sides of thorax not parallel, its base usually much wider than apex. 



6. Thorax not sinuate on sides between middle and base, widest before 



the base (Fig. 38, a, c.); surface bronzed. 



c. First joint of antennae pale; tibiae and base of femora reddish- 

 brown; length 2.4 mm. 86. SMITHII. 

 eo. Antennae and legs entirely dark; thorax much wider than long; 

 length 1.5 2 mm. 87. METALLICUM.* 



* Species marked thus * are so far known only from the South Atlantic coastal 

 region. In addition to the species of the key, A. tcniiirostntni Smith, for which the 

 distribution is Kansas, Nebraska, Texas, Colorado and Montana, is included in Ulke's 

 D. C. list, and Smith gave D. C. as one of his localities in the original description; also 

 A. oblitum Smith, for which the distribution is Texas, Colorado and Nebraska, is in- 

 cluded in Smith's New Jersey list, and Smith himself included Florida among his original 

 localities. We have omitted both, however, as they are plainly western species, found by 

 accident or misidentified in the East.
