170 THE CANADIAN ENTOMOLOGIST. 



the scutum with some large punctures, which are scattered and incon- 

 spicuous, and clotlied with short stiff prostrate gray or silvery hairs, 

 which, however, are absent at the meson of the caudal ihree-fourths of the 

 sclerite and along the caudal margin, some distance laterad from the 

 meson; scutum and scutellum subequal in length, the latter slightly longer; 

 axillae cuneate, joining at base of scutellum ; scutellum with a conspicuous 

 tuft of black hairs at its dorsal apex. Abdomen conic-cylindric, equal to 

 combined length of head and thorax, the hypopygium prominent, 

 extending one-fifth the length of the abdomen beyond the anal extremity. 

 Wings infuscated beyond the submarginal vein, with the extreme apex 

 hyaline however; marginal vein slightly thickened, linear, thrice the length 

 of the stigmal vein, which is nearly twice the length of the postmarginal 

 vein, the latter distinct ; a short V-shaped, hyaline, hairless marking 

 present, its apex along the costal margin just beyond the postmarginal 

 vein, one branch running slightly apico-caudad (normal position) across 

 the truncate end of the stigmal vein, the other proximo-caudad, into the 

 angle subtended by the junction of the stigmal and postmarginal veins; 

 also an oblique (meso- or proximo-caudad) hairless line running from the 

 stigma, but included within the coloured area of the fore wing, and hence 

 somewhat obscured. Marginal cell of hind wings long. Wings extending 

 beyond abdomen, and slightly beyond the hypopygium. Legs normal. 

 Mandibles bidentate, the outer tooth shorter, obtuse, and one-third as 

 broad as the inner, which is broadly truncate at apex. 



Nearest to Chrysopophagus Ashmead, and separated from it by the 

 slightly dilated scape, the longer pedicel, the less noticeable compression 

 of the antennae, and the differently shaped, more rounded head, and by 

 mandibular characters, the mandibles in Chrysopophagus being distinctly 

 3-dentate, the two inner (mesal) teeth being equal and slightly smaller than 

 the outer (lateral) one, and less acute. And liable to be confused with 

 Habrolepis Foerster and Eusemion Dahlbom, of the tribe Mirini.
