DESCRIPTIONS OF SOME NEW GENERA AND SPECIES OF 

 CANADIAN PROCTOTRUPID^E. 



BY WM. H. ASHMEAD, JACKSONVILLE, FLORIDA. 



The following paper is devoted to the description of new genera and 

 species of parasitic Hymenoptera belonging to the family Proctotrupidae, 

 collected at Ottawa, Canada, by my esteemed friend, Mr. W. Hague 

 Harrington, to whose liberality I am deeply indebted for sending me these 

 and many other interesting forms in this family now in my collection. 



Sub-family Ceraphronin^e, 



The following table will be found useful to separate some forms closely 

 allied to the genus Megaspilus Westwood. 

 Eyes hairy. 



Metathorax spined Megaspilodes Ashm. 



Metathorax not spined. 



Wingless, or with rudimentary wings 2 



Winged ; a large semi-circular stigma and a stigmal vein. 

 Mesothorax with three grooves ; g antenna; filiform, <? flagel- 

 late Megaspilus Westw. 



2. $ antennas sub-clavate ; <£ unknown. Eumegaspilus, n. g. 



Mesothorax with only a median groove Megaspilidea, n. g. 



Megaspilodes Ashm. 

 The writer has recently characterized this genus elsewhere. It is at 

 once distinguished from Megaspilus Westw. by having a blunt spine, or a 

 bi-forked spine, in the middle of the metathorax. Two species pertain to 

 it, viz., Megaspilodes arm at us Say, and M. fuscipennis Ashm. 



Megaspilus Westwood. 



(1) Megaspilus ffarringtoni, n. sp. 



Male and female. Length .07 to .10 inch. Black; head and thorax 

 finely reticulately sculptured; abdomen polished black. Antennae 11- 

 jointed, the scape and pedicel dull honey-yellow, the flagellum brown- 

 black. Legs dull honey-yellow, the posterior femora obfuscated, the 

 anterior and middle coxae honey-yellow at apex, while the large posterior 

 coxae are black. Wings sub-hyaline, heavily pubescent, the large stigma 

 and stigmal vein brown. The male differs from the female only in its 

 smaller size, and is readily distinguished by its long, filiform antennae, the
