222 THE SCOLYTID BEETLES. 



ariccse (Hornimg, 1S42, p. 117 [not 115]) because he found that cer- 

 tain species previously referred to Hypoihenemus had five joints m 

 the fimicle of the antenna instead of three, as designated bv West- 

 wood. 



Faiivel (1884, p. 315) exammed specimens of H. eruditus Westw. 

 from the type series and compared them with examples of Bostrichus 

 hoieldieui Perroud, 1864, p. 188, and B. ariccx Hornimg, 1842, p. 117, 

 identified by Eiclihoff, and concluded that all three were identical, 

 and that HomoBocryplialus Lind., 1876, p. 168, as represented by 

 StepJmnoderes elilersi Eichh., was identical with Hypothenemus Westw. 



Newberry (1910, p. 83) determmed that the funicle had four 

 joints. 



Through the kindness of Prof. Poulton, the writer had the oppor- 

 tunity of examining a specimen of H. eruditus Westw. from the type 

 series, and the funicle was found to be four-jointed. It is not improb- 

 able, however, that the antemia examined by Westwood was from a 

 male, which, m this genus, is smaller than the female and has but 

 three joints in the funicle. Therefore there can be no doubt as to the 

 validity of the genus Hypoihenemus Westw. as distmguished from 

 the genus StepJianoderes Eichh., which has a five-jointed funicle. 



Genus POLYGRAPHUS Erichson. 



Erichson (1836, p. 57-58) described the genus Polygraplius, citing 

 Dermestes polygraplius L. (1758, p. 355) as synonymous with P. 

 pubescens Fab. (1792, p. 368) ; but since P. polygraplius L. has priority, 

 the genus stands with Dermestes polygraplius 1j. as the type. 



Genus LEPISOMUS Kirby. 



Kirby (1837, p. 193) described Lepisomus as a subgenus of Apate 

 Fab., mcluding three species, one of which, Apate {Lepisomus) 

 nigriceps, has been referred to synonymy (Lee, 1868, p. 169) while 

 Apate {Lepisom^us) hrevicornis is not recognizable, probably a synonym. 

 Therefore Apate {Le-pisoraus) rufipennis Kirby is the type of the 

 genus Lepisomus, which, on account of the six-jointed funicle, is a 

 good genus. For the same reason Polygraplius grandiclava Thorn. 

 (1886, p. 62) must also be referred to this genus. 



DESCRIPTION OF A NEW GENUS AND SPECIES. 



WEBBIA n. gen.a 



Antennal funicle four-jointed, the fourth broad; club narrowed 

 from middle to base, broader than long, with one sinuate clfitinous 

 suture on the obliquely truncate anterior face, the posterior face 



o- This genus and species is described here in order that the subfamily may be 

 included in the classification.
