shining-aeneous in some aspects, finely punctate and bearing de- 

 pressed white hairs ; the scuteHum black, dull, but with the ex-

 parasitic on Goiiatopus and allied genera. 



Ecliflirogouatopus pacJiyccl^Jiahis, sp. nov. 



General appearance quite like the preceding, but the head is 

 rather strongly incrassate, the space between the great eyes 

 extremely long and norrow, the ocelli forming an isosceles tri- 

 angle, twice as high as its basal width, and the marginal vein is 

 shorter and thicker. 



Head with very dense and fine microscopic sculpture and with 

 evidence of a few large, but very feeble, punctures in the region 

 of the ocelli, the antennae yellowish or testaceous, not dififer- 

 ing much in structure from those of the preceding. Mesoriotum 

 aeneous, shining, and with very dense sculpture. Legs pale 

 yellowish. Abdomen shining metallic green at the base, else- 

 where purplish black. Length f mm. Male not known. 



HAB : Ohio, U. S. A. ; bred from cocoons of Goiiatopus or 

 some allied form, collected by Koebele. 



Hclcgonatopus, gen. nov. 



In general appearance and structure excessively like Echtlvo- 

 gonatopus exitiosns, but the male differs at once by the funicle 

 having only five joints, which are very elongate, the pedicel be- 

 ing much shorter than the first of these ; the female by the small 

 club, only about as long as two or three preceding ijoints; and 

 both sexes by the longer stigmal vein and short marginal, the 

 latter being not or hardly longer than the former.
