having on each side a reddish-yellow spot, tliose on the last segment 

 being the largest and most irregular. 



Head feebly convex with a distinct longitudinal carina, surface 

 coarsely and rather densely punctate, and sparsely clothed with a few 

 short inconspicuous hairs; epistoma broadly, but not very deeply 

 arcuately emarginate in front. Pronotum nearly two times as wide 

 as long, widest at base or basal fourth, narrower in front than 

 behind ; sides arcuately expanded at basal half, then obliquely atten- 

 uate to the apical angles; posterior angles rather obtuse; anterior 

 margin feebly arcuately emarginate, with a broadly rounded median 

 lobe; disk with large sublateral smooth spaces, and a distant smooth 

 median line, which is finely striate at base; surface coarsely, but not 

 densely punctate, the punctures irregularly placed and more con- 

 fluent toward the sides. Scutellum rounded, transverse^ oval or 

 subquadrate. Elytra slightly wider than pronotum at base, expand- 

 ed behind the humeri, nearly parallel to apical third, then arcuately 

 attenuate to the tips, which are rounded or truncate, and finely irreg- 

 ularly dentate, the outer angle obtuse, and never dentiform ; surface 

 feebly striato-punctate, the striae finely and rather closely punctured ; 

 intervals coarsely, sparsely and irregularly punctate, those between 

 striae 2-3, 4—5, and 8-9 elevated, and forming obtuse ridges. Abdo- 

 men beneath coarsely and rather densely punctate, and sparsely 

 clothed with short inconspicuous hairs, first segment broadly, longitu- 

 dinally sulcate at middle; last segment sinuate, truncate or rounded 

 at apex. Prosteinum nearly flat, coarsely and irregularl}' punctate, 

 and nearly glabrous; anterior margin feebly arcuately emarginate: 

 prosternal process feebly convex, not sulcate at middle, gradually 

 attenuate to the apex which is rather acutely rounded. Anterior 

 femora strongly swollen at middle; anterior tibiae emarginate, flat- 

 tened on inner side and armed with a large broad hook at the apex ; 

 anterior tarsi distinctly broader than the posterior ones. 



Female. — Similar to the male, but the anterior tarsi not distinctly 

 broader than the posterior ones, and the anterior tibiae not armed 

 with a hook at the apex. 



Lenth, 12-20 mm. ; width, 4.5-7.5 mm. 



Originally described by Say (1824) from the United States. This 

 species seems to be confined to the northeastern part of North 

 America and its distribution extends from Newfoimdland to Penn- 

 sylvania and westw^ard to Minnesota. The larvae live in various 

 coniferous trees and the adults have been found emerging from 

 pine timber, and have probably been introduced into Haiti in such 

 produce. The following material of this species has been examined. 

 Coll. British Mus. ; two specimens labelled " Haiti, compared with 

 type, 6-notata Castelnau and Gory, Saunders, 74-18."
