 CANADIAN PROCrOTRYPID.E:. 



BY WILLIAM H. ASHMEAD, WASHINGTON, D. C. 



The following new genera and species of Proctotrypidae were all 

 collected in Canada by Mr. W. Hague Harrington, of Ottawa. 



ScoRPiOTELEiA, gen. nov. 



Abdomen with five visible segments ; the last three segments long, 

 slender, cylindrical, together as long as the second, and resembling the 

 terminal segments of a scorpion ; the third segment is about as long as 

 the fourth and fifth segments united, the fifth pointed. Front wings with 

 the marginal vein shorter than the marginal cell, and scarcely twice as 

 long as the first abscissa of radius, which is slightly oblique. Antenn:o 

 15-jointed, filiform, the first joint of flagellum the longest, about half the 

 length of the scape, the following joints to the last very gradually shorten- 

 ing, the penultimate joint being about twice as long as thick, the last 

 joint oblong-oval, one-half longer than the preceding, 

 (r) Scorpioteleia mirabilis, sp. n. 



5 . — Length, 4 mm. Smooth, shining, pubescent ; head and thorax 

 black, collar and prosternum brownish ; petiole and the large second 

 abdominal segment brownish-piceous, the three terminal segments yel- 

 lowish ; mandibles, legs and b.isal four joints of antenna ferruginous, the 

 flagellum blackish towards apex ; palpi yellowish. 



The mesonotal furrows are deep, distinct ; the scutellum has a large, 

 deep fovea across the base ; while the metanotum is smooth, tricarinate, 

 with the posterior angles subdentate. Wings hyaline, pubescent, the 

 tegulfe yellowish, the veins broad. Abdominal petiole longer than the 

 metathorax, a little thicker towards base than at apex, striated, about 

 three times as long as thick, rest of abdomen smooth, polished. 



Hab. — Kettle Island, in Ottawa River, August 18, 1894. 



Stylidolon, gen. nov. 



Abdomen with six visible segments, the body of same being long and 

 very slender, twice as long as the petiole, and gradually acuminate to- 

 ward apex, which has a gentle upward curve ; the second segment is 

 scarcely longer than the petiole, the dorsum of same triangularly emargi- 

 nated at apex ; the third segment dorsally, on account of the emargination 

 in the second, a little longer than the fourth and fifth, but ventrally it is 

 not longer than these two segments united ; the fifth is shorter than the 

 fourth ; the sixth is conically pointed, a little longer than the third. Front
