CAMPTOCERUS. 
Camptocerus, Latreille, Régne anim. ed. 2, v. p. 91; Lacordaire, Gen. Col. vii. p. 368; Chapuis, 
Syn. Scol. p. 50 (Mém. Soc. Liége, 1878, p. 258). 
An interesting genus, which contains the first Scolytide described from America. 
Fabricius (Syst. Eleuth. ii. pp. 392, 393) diagnosed five species of Hylesinus, which 
Erichson subsequently referred to this genus; of these two alone were recognized by 
Chapuis, who added three more, of which C. cinctus may be identical with Hylesinus 
fasciatus, Fabr. 
Thus the number of described species does not exceed eight, and of these C. enei- 
pennis, Fabr., alone is common in collections. It is surprising that no more have ever 
been described ; for Scolytide, they are striking in appearance. 
The genus is South American, and one species only has strayed into our region. 
1. Camptocerus auricomus, sp.v. (Tab. V. figg. 11, ¢; lla, front; 114, 
portion of elytral surface: 12,2; 12a, front.) 
Ovalis, postice angustatus, breviter pilosus; prothorace transverso, dense subtiliter punctato; elytris tenuiter 
striatis, interstitiis dense squamosis, squamis ad apicem longioribus vel subsetosis. 
Mas. Piceo-ferrugineus, fronte excavata, pilis aureis bifasciata, margine orali tuberculato; elytris flavo- 
squamatis versus apicem fascia transversa obscuriore obsolete notatis. 
Long. 3°8 millim. 
Fem. Piceo-nigra, fronte convexa; prothorace versus apicem aciculata; squamis elytrorum fuscis, ad basin et 
in plaga postica pallide flavis. 
Long. 2°9-3-6 millim. 
Ovate, narrowed from the middle of the prothorax to the hinder extremity, red-brown ( ¢) or pitchy-black ( ? ), 
Front (3) broadly excavate, the excavation sharply limited, dull and furnished with two bands of decum- 
bent yellow hairs, epistoma with a median tubercle above a brush of yellow cilia; antennxe fuscous- 
brown, the club darker, somewhat trigonate in shape, pubescent, with traces of one or more strongly 
curved sutures, scape much thickened at apex, funiculus stout, somewhat twisted, joints 2-7 furnished 
with long stout cirri, reaching to the apex of the club. Front (?) convex, dull, shortly pubescent, 
with traces of a carina over the fringed mouth; antenne testaceous-brown, shorter and more slender, 
the funiculus much shorter, not appendiculate, the club more regularly ovate, pubescent, with indistinct 
sutures. Prothorax transverse, widest in the middle, strongly bisinuate at base, and subcircularly 
rounded at apex; disc with thin decumbent pubescence, yellow (¢), fuscous (2), and a few scales 
towards the apex, very finely and closely punctate, the apical half ( 9 ) longitudinally strigillate. Elytra 
a third longer than the prothorax, and as wide at the base, thence narrowed to apex; finely striate, the 
interstices flat, closely squamous; the scales (¢) large, semierect, long and setiform on the declivity, 
yellow, darker over an indistinct transverse vitta towards the apex, the scales (  ) shorter, setiform but 
not elongate on the declivity, fuscous-black, and pale yellow over a triangular basal patch and another on 
the declivity. Underside piceous red (¢), last three ventral segments fringed with long yellow hairs ; 
piceous-black (  ), with shorter and darker fringes. Legs concolorous.
