176 THE CANADIAN ENTOMOLOGIST. 



but which, however, widens at the lateral third, extending cephalad, laterad 

 and caiidad to the respective margins ; metanotiim concolorous with the 

 scutelkim, excepting dorso-laterally, where it is ochraceous ; tegular 

 ochraceous, obscured in the disk with some bluish ; clypeus conspicuously 

 dark brown, from side to side ; head between the vertex and front, 

 between the eyes, variable, frequently tinged with lustrous purple, visible 

 in certain lights only ; legs ochraceous, the caudal femora and tibiie, how- 

 ever, flushed with bluish, the intermediate tibite more delicately so, the 

 apical tarsal joint dark; antennse black, the 5th and 6th funicle joints white; 

 scape at the peduncle and extreme apex ochraceous, and the pedicel and 

 first two funicle joints dusky, lighter ventrad; dilatation of the scape some- 

 what metallic and with some bluish. Fore wings fuliginous to end of the 

 stigmal vein, the apical margin of the fuliginous area convex ; from thence 

 apicad, hyaline, but through the midst of this, nearer the fuliginous area than 

 to the apexof the wing, runs transversely (cephalo-caudad) a broken band of 

 fuliginous, consisting of four distinct portions, two subequal subquadrate 

 spots leading caudo-apicad from the cephalic wing margin, a smaller rounder 

 dot in the middle of the wing, further proximad, and then leading to the 

 caudal margin, apico-caudad, a longer columnar area ; if joined together 

 the line formed would be ^ - shaped; venation brownish-black. Eyes dark; 

 ocelli ruby-red. 



Head slightly wider than long (cephalic aspect), sublenticular, as 

 wide as the thorax at its widest point, from lateral apex deflexed, the facial 

 impression normal and margined caudad, the scrobes forming a semicircle, 

 the mesal portion of the impression carinated for a short distance along 

 the median line near the caudal margin. Face between the eyes and the 

 vertex as in Cristatithorax pulcher Girault. Eyes nearly circular, their 

 mesal margin somewhat flattened, rather large and on the cephalo-lateral 

 aspect of the head, their caudal margins invading the sharp occipital 

 margin ; ocelli not near the occipital margin, in a nearly equilateral 

 triangle, the lateral ones oval and nearly touching the eye margins, and 

 slightly nearer to each other than either is to the cephalic ocellus, which 

 is circular. Occipital margin acute, convex. Pro- and mesonotum and 

 the mesopleurum squammose, the two former with regularly scattered, 

 obscure punctures, which are less conspicuous on the scutelhmi and axillae^ 

 each puncture giving origin to a reclinate, short, dull grayish seta ; meso- 

 scutum slightly shorter than the scutelUim along the meson, its caudal 

 margin regularly convex ; axillce acutely cuneate, meeting at the meson, 

 where they are subaccuminate ; scutellum peltate, normal, without a tuf
