158 GEO. H. HORN, M. D. 



Q. spelcens Horn. Trans. Am. Ent. Soc. 1871, p. 332.— Form elongate. 

 Head oval, longer than wide, surface smooth and shining, two supra-orbital 

 punctures distant from the eyes and another behind the eye, behind which 

 are some smaller punctures; neck moderately constricted. Labrum bilobed. 

 Eyes oval, slightly oblique, and subtruncate in front. Antennae filiform, one- 

 half longer than the head, joints 4^10 similar, last joint longer and obliquely 

 truncate. Thorax broader than long, narrowed in front, sides feebly base more 

 broadly arcuate, margin near base explanate, surface highly polished and with 

 three discal and the marginal punctures as in explanatus. Scutellum smooth. 

 Elytra narrower than the thorax, conjointly as wide as long, surface closely 

 punctulate and sparsely clothed with brownish hair. Abdomen parallel, above 

 more sparsely punctured than the elytra, the punctures denser at the sides 

 and anterior portions of the segments. Body beneath more sparsely punc- 

 tured than above. Femora punctate, tibise spinulose. Length .56 — .60 inch; 

 14 — 15 mm. 



The anterior tarsi are dilated ia both sexes but much more in the 

 male, in which also the sixth ventral segment is feebly emarginate 

 at middle. 



The post coxal process is of moderate extent and semi-corneous. 

 The thorax in general outline is nearly circular less the apical 

 emargination. The color in the three specimens before me is pale 

 brownish testaceous, varying to pale castaneous. 



Two specimens were collected by Prof Cope within the mouth of 

 Wyandotte Cave, Indiana, a third is from Colorado by Morrison.

 Lappon. 61, 13; erythrogaster Mann. Bull. Mosc. 1852, ii, p. 314; melanocephalus 

 Mann. loc. cit. p. 315. — Form moderately elongate. Head oval slightly broader 

 than long '^ ,or as long as wide 9 > surface smooth polished and with moderate 

 punctures on each side, the first small over the insertion of the antennae, second 

 near the inner margin of the eye, third larger distant from the eye, a fourth 

 post-ocjalar around which are numerous smaller punctures, neck feebly con- 

 stricted. Eyes not prominent, slightly oblique, subtruncate in front. Antennae 

 piceous or rufo piceous, filiform, attaining the middle of the thorax, joints 4 — 10 

 as wide as long, eleventh longer and subacute at tip. Labrum bilobed. Thorax 

 slightly wider than Jong, narrowed in front, apex emarginate, sides feebly arcu- 

 ate, margin not explanate, base broadly arcuate, surface smooth and shining 

 and with the three discal punctures on each side of middle in front, another 

 series of three exterior to this and numerous marginal and basal punctures. 

 Scutellum smooth. Elytra as wide as the thorax, conjointly wider than long, 

 surface regularly and moderately coarsely but not densely punctured and 

 sparsely pubescent. Abdomen more finely and densely punctured than the 

 elytra, sparsely pubescent, beneath more coarsely punctured. Femora punc- 

 tate, tibise spinulose. Length .28 — .44 inch ; 7 — 11mm. 



The anterior tarsi are about equally dilated in the sexes. The male 

 has however a larger head and the sixth ventral feebly emarginate 

 at middle.
