anteimaB is depressed. The nasal plate is elongate triangular, dis- 

 tinctly rimmed, concave, emarginate. The scrobes are deep at base 

 but rapidly evanescent at a considerable distance from the eyes; the 

 alse are prominent, causing a considerable widening of the beak at 

 apex. Scape strongly clavate not reaching the middle of the eyes; 

 funicle with the first two joints elongate, the remainder moniliform, 

 widening toward club; club short, oval, but Httle longer than the two 

 preceding joints. Eyes rounded, strongly prominent, convex. Two 

 Httle areas of scaly vestiture bordering the inner edges of the eyes 

 are the only striking areas of vestiture on the head or beak. Pro- 

 thorax as long as wide, convex at base, truncate at apex, slightly 

 convex at sides; ocular lobes broad and veiy slightly convex, not 

 prominent, vibrissse lacking; surface above very strongly tuberculate 

 with punctured tubercles which bear tiny hairs in the punctures; 

 median lines shghtly indicated; scaly vestiture sparse, arranged 

 principally in broad lateral fasciae and two transverse fascia from 

 these at the middle turning forward near the median line of the thorax 

 and extending to the apex. Elytra oval, with rounded humeri; inter- 

 spaces aU tuberculate with flattened shining tubercles each punctured 

 beliind, with a tiny seta in each puncture; strial punctures very 

 shallow; scales arranged principally in humeral fasciae extending 

 obliquely back to the middle of the elytral suture, and m an apical 

 fascia extendmg transversely from near the suture to the sides at the 

 vertex of the apical declivity and then passing along the sides to the 

 apex. Undersides closely, shallowly punctate, without vestiture 

 except smaU patches on the sides of the metasternum and the second 

 abdominal segment. Metasternal side pieces covered by the elytra 

 (in the type the pin has pushed the abdomen down and exposed the 

 side pieces). First abdominal suture straight; the second segment 

 transversely impressed at its middle, about as long as the two follow- 

 ing. Femora clavate, the middle and hind pairs externally clothed 

 with a patch of golden scales near apex; femora punctate, each 

 puncture setigerous; tibiae mucronate, minutely denticulate, spinose; 

 posterior corbels oblique. 



Type.— Cat. No. 14639, U.S.Nat.Mus. 



Subgenus PANSCOPUS Schonherr. 



This subgenus is adequately defined in the table preceding. The 

 type is erinaceus Say. 



PANSCOPUS (PANSCOPUS) ERINACEUS Say. 



This species as formerly interpreted by the writer contained also 

 alternatus and carinatus. The only specimens which fit the original 

 description are from Buffalo, New York; New Hampshire; Wash- 

 ington, District of Columbia; Plummers Island, Maryland; and 

 Berkeley, West Virginia.
