No. 22.] HYMBNOPTERA OF CONNECTICUT. 765 



embo^ed area on the second dorsal abdominal segment extend- 

 ing a little beyond the middle, apex of second dorsal segment 

 subemarginate, the false suture between the second and third seg- 

 ments crenulate; abdomen reddish throughout and mostly poU 

 ished, the second dorsal segment with a faint carina on the 

 middle of each side ; hypopygium sharply pointed and surpassing 

 the pygidium; exserted portion of ovipositor nearly as long as 

 the body. 



The sculpture of the second dorsal abdominal segment is sub- 

 ject to variation, and the basal embossed area on the third dorsal 

 segment may be poorly developed or virtually wanting. 



Type locality : Rainbow. Reared from shoots of Pinus rigida 

 infested by Pissodes strohi, June 25, 1910 (S. N. Spring). 



BRACONID^. 

 Bucculatriplex Viereck. 



Related to Heterogamus Wesmael, from which it differs es- 

 pecially in the Polystenidea-likQ abdomen, there being four ab- 

 dominal segments visible dorsally; in the second segment being 

 nearly twice as long as the first and distinctly longer than the fol- 

 lowing segments combined; in the trapezoidal second submar- 

 ginal cell ; in the simple propodeum with a petiolarea and a me- 

 dian longitudinal carina from the latter to the base; and in the 

 faintly impressed sternauli. 



Heterogamus does not occur in Connecticut. In the table of 

 Connecticut genera of Sigalphidas this genus agrees best with 

 the description of Aleiodes, from which it differs radically in the 

 abdomen as described above.

Female: length 1.75 mm.; blackish brown; face including 

 clypeus, mouth parts, malar space and lower part of cheeks, scape,

 a yellowish cast, the veins and stigma very pale stramineous; 

 tarsal joints especially apically, onychii and claws throughout
