Type. — In the Museum of Public Instruction at Quebec. 



This species is very distinct from all other species of Microgaster^ 

 in that the propodeum is almost horizontal ; also in possessing a fine 

 but distinct crenulate furrow on the mesopleurae; in the somewhat 

 shorter tibial spurs; and the very large apical tarsal segment. The 

 abdomen is long, with nearly parallel sides ; the first two abdominal 

 tergites large and coarsely rugose; the third and fourth tergites 

 are usually partly testaceous, also the venter of the abdomen, and 

 the posterior coxae. 



Canada ; New York ; Massachusetts ; Maine. 



Host. — Unknown. 



The National Collection contains a homotype (determined by Ga- 

 han), from Ottawa, Canada; one other specimen from the same 

 locality; one from Long Island, New York; one from Ithaca, New 

 York; and one labeled " Cana. 2068, Collection C. F. Baker." I 

 have seen in Doctor Brues's collection five specimens from Woods 

 Hole, one from Fall River, and one from Essex County, Massachu- 

 setts. The collection of the Boston Society of Natural History has 

 five specimens collected by Mr. C. W. Johnson on Mount Desert, 

 Maine, and two taken by the same collector at Williamsburg, Massa- 

 chusetts. The Cornell Collection contains a single specimen from 

 Spring Lake, Cayuga County, New York.

 Type. — In the Museum of Public Instruction at Quebec, Canada. 

 I have seen no specimens of this species. It has been assigned its 

 place in the key on the basis of the original description, and notes by 

 Mr. Gahan, made upon an examination of the type. 



15. MICROGASTER HARNEDI, new species. 



Very similar to pantographae, from which it can be separated 

 however, by the characters noted in the table to species. 



Female. — Length 4 mm. Face ruguloso-pnnctate, witli a short 

 polished median ridge below antenna! fossae; clypeus well sepa- 

 rated from face; vertex and temples weakly punctate and shining; 

 antennae nearlj^ as long as Ihe bod}^; mesoscutura punctate and shin-
