rarely confluent into short transverse lines. Thorax one-third wider 

 than long, sides moderately strongly arcuate, surface densely punctured, 

 very sparsely pubescent, slightly denser along the median line. Elytra 

 oval, gradually attenuate to tip, disc moderately convex, striate, strias 

 punctured, intervals densely, but not roughly punctured, surface moder- 

 ately densely clothed with pale-brown, with numerous pale-orange spots, 

 sometimes confluent into short fasciae. Body beneath moderately densely 

 clothed, paler than above. Femora dentate as in caryatrypes. Tarsal 

 claws with the basal appendix narrow. 



Male. — Rostrum slightly shorter than the body, moderately arcuate. 

 Abdomen with eight segments above, pygidium at tip deeply concave, 

 the concavity smooth, shining and surrounded by an acute rim fimbriate 

 with long hairs. 



Female. — Rostrum longer than the body. Abdomen above with seven 

 segments, pygidium fimbriate, convex. 



This species is abundantly distinct by the sexual characters. 



There are numerous specimens before me reared by Mr. John Akhurst, 

 of Brooklyn, N. Y., and one from Texas, from M. Salle (No. 65).

Form moderately slender, color piceous, clothed with brownish scale- 

 like hairs, elytra with numerous pale-yellow spots, more or less confluent. 

 Thorax longer than wide, more or less conical, sides very feebly arcuate 

 or nearly straight from apex to base, surface moderately convex, densely 

 punctured, median line slightly elevated, smooth, clothed with brownish 

 hairs with a paler line near the side. Elytra oval, rapidly attenuate to 

 base, surface striate, striae punctured, intervals fiat, densely punctured, 

 densely clothed with brownish pubescence, with numerous pale-yellow 

 spots more or less confluent, sometimes forming fasciae. Body beneath 

 with paler, more silken scales. Femora with rather strong triangular 

 tooth, slightly sinuous on its distal edge. Claws with moderately broad 

 basal lobe. Length .20-26 inch ; 5-6.5 mm. 



Male. — Rostrum shorter than the body, feebly arcuate. Pygidium con- 

 vex at tip, punctured and pilose. 



Female. — Rostrum nearly twice as long as the body, moderately arcu- 

 ate at tip. Pygidium less pilose. 



Occurs in the Middle and Southern States.

* The descriptions given by Say, are absolutely valueless, consequently the descriptions of 

 Gyllenhal from types sent by Say, must be relied on in determining the species of the latter 

 author. This appears to be the species supposed to be proboscideus Fab. by Say. As none of 

 Say's types are extant, the only way out of the difficulty appears to be to accept the descrip- 

 tions of Gyllenhal, and determine synonymy directly from them.
