antennse, mandibles, coXcXi, aud the tliickcned portion of the femora and 

 tibia' iiiceons or brown-bhick, rest of the legs rufous ; the pedicel is 

 stouter and a little longer than the first funiclar joint, the joints be- 

 yond to the sixth very gradually decreasing, but slightly thickened ; the 

 seventh large, oval, the three terminal joints greatly enlarged, the 

 last oblong. Fovea of scutellum smooth at base, separated into two 

 parts by the scutellar carina, the sides not densely pubescent. Meta- 

 thorax with a prominence at base and foveated at sides, nearly bare. 

 Tegulfe black. AVings subhyaline, pubescent. Abdomen not longer 

 than the head and thorax united, not conically pointed at apex, and 

 depressed, the i)etiole not much longer than thick, fluted; the second 

 segment occupies the greater portion of its surface, the third short, 

 slightly longer than the fourth, the fifth longer than the third, the 

 sixth not longer than the fifth. 



Habitat. — Canada, and l^nrope. 



Specimens in Coll. Ashmead. 



A single specimen received from Mr. W. H. Harrington, taken at 

 Ottawa, Canada, could not be separated from Eurojiean si)ecimens of 

 this si^ecies in my collection, and, like T. conica, it has probably been 

 imported into this country on some Dipterous host.

9 . Length, 2.8""". Closely allied to G. carinata, but with the fol- 

 lowing distinct differences : The pedicel and two or three funiclar joints 

 are more or less rufous, the pedicel much shorter than the first funiclar 

 joint, and the club really begins with the fifth funiclar joint, the joints 

 from the sixth to the last being quadrate, the last conic; scutellum 

 with a large, smooth fovea at base, without raised lines at bottom and 

 not separated into two parts by the forward extension of the median 

 carina; tegulse black ; wings hyaline; the legs show more rufous than 

 in D. carinata^ the femora and tibiiie not being so dark ; petiole of abdo- 

 men longer, more xjubescent, and not distinctly fluted; the third seg- 

 ment is longer than either the fourth or the fifth, the latter very slightly 

 longer than the fourth, while the sixth is very little longer than the 

 third. 



Habitat. — Ottawa, Canada.

Described from Provancher's type, given me by Mr. W. H. Harring-

Tripidopria siniulans, sji. nov. 



9 . Length, 2 to 2.5"'"'. Approaches nearest to T. torquata, but differs 

 as follows: Antennae dark rufous, very gradually clavate, more slender 

 than in torquata, the pedicel one-third shorter than the first funiclar 

 joint, the funiclar joints to the fifth slender, decreasing in length, the
