164 THE CA.NADIAN ENTOMOLOGIST. 



besides the usual row of bristles on the front, there is a second row of 

 three bristles on each side, between the first row and the orbit of the eye ; 

 the upper bristle of this second row is placed near the upper corner of 

 the eye, alongside of the upper bristle of the first row ; the second and 

 third bristles are inserted lower down on the front. The usual inner row 

 of frontal bristles consists of three bristles on the vertex, pointing back- 

 wards, the upper one of which is the longest, and of six bristles below 

 them, descending rather low on the face, considerably below the end of 

 the second antennal joint. The pair of bristles on the ocellar triangle is 

 present. Above the usual long bristle on each side of the oral border 

 there is a row of small hairs, ascending along the ridge of the face, but 

 not reaching the level of the lowest bristle of the frontal row. Antennae 

 black, third joint with parallel sides, broader than in E. fntilis and 

 E. blanda, but at the same time shorter, as it does not reach the oral 

 border. First half of the arista remarkably stout ; its basal joint long 

 and distinct. Palpi dark brown or black. Face and front silvery ; oral 

 margin pale ; frontal stripe brown ; ocellar triangle blackish, grayish 

 poUinose. Eyes pubescent. Thorax bluish-black, grayish-pollinose ; 

 two sub-parallel, soon interrupted, black stripes in the middle, and two 

 less definite lateral stripes, black. Pleurag black, with a light-grayish 

 pollen. Scutellum black, grayish-pollinose, its hind margin yellowish ; 

 the two lateral pairs of macrochetae rather long and strong ; the inter- 

 mediate one small ; a pair of small macrochetae on the disc. Abdomen 

 black, marmorate, with grayish-silvery reflections, especially on the 

 anterior borders of the segments ; a pair of macrochetas on the hind 

 border of the first segment (I believe that I perceive them in my only 

 specimen, although its abdomen is so much crowded against the 

 scutellum that this character is not easily discernible); on the second 

 segment, a pair of macrochetae in the middle only ; on the third, the 

 usual row of macrochetae along the hind border ; on the fourth, a number 

 of macrochetas, giving it a bristly appearance ; the smaller hairs of the 

 abdomen are more erect, longer and bristle-like than in E. fntilis or 

 E. blanda. Feet black. Wings nearly as in E. fntilis. 



Bred from Ficris rapce in April (Lintner).
