artf) THK CANADIAN ENT<>MOI.f»OIST. 



ihe last nearly twice as broad as the first ; club oval, not much enlarged. 

 Surface of head roughly shagrecned above and on the front, more finely 

 so behind the eyes. Clypeus sllijhtly prolonged into a short, almost 

 truncate lobe. Left mandible with three teeth, right one with four. 

 Palpi light yellow. Mesonolum coarsely shagreened or finely reticulate 

 punctate, as long as broad. Axilla^ separated by their own width, more 

 finely sculptured than the mesonolum. Scutellum very convex apically, 

 in front finely sculptured like the axillae, but much more coarsely so at 

 the apex ; without cross-furrow. Melathorax with a very distinct median 

 carina. Spiracular sulci present, but not veiy deep ; lateral folds very 

 distinct at the base, but evanescent apically. Mesopleura roughly 

 shagreened, but with a large triangular polished space above. Abdomen 

 nearly as long as the thorax, scarcely produced below, and flit above, 

 with the apex raihc suddenly narrowed and pointed. Wings hyaline, 

 veins weak brownish-yellow ; nurginal vein three-fifths as long as the sub- 

 marginal, long and slender, and about as long as the postmarginal ; 

 sligmal vein slender, three fourths as long as the marginal, with a small 

 knob at its apex. 



Male: Differs from the female by its more slender form, bright 

 metallic green colour and paler legs. The legs, except coxce, are pale 

 yellow, with only the last tarsal joint blackened, and the antennas are also 

 pale brownish-yellow, somewhat infuscated toward the apex. 



Described from two females and two males received from Dr. C. 

 Gordon Hewitt, Dominion Entomologist, Ottawa, Canada. They were 

 reared early in August by Mr. Arthur (libson, of the Entomological 

 Division, from pupne of the sjjiuce bud worm, Tortrix fumifeiana, 

 coliecied at Haskatong, Quebec, where the caterpillars were feeding on 

 s|)ruce and balsam. 



This species appears to be referable to Naconia ,'\shm., although it 

 will not well run to this genus in Ashmcad's tab'e. It agrees better with 

 his characterization of .\farn:o>iie/iii, which Mr. N. W. KourdumofT, who 

 has seen the type in Washington, tells me is based on the 5ame ty|)e 

 specimen as Nuionia, .\shinead having given also the same manuscript 

 name (brevicomis ) to tlie type species of both genera. Since Girault 

 has more recently (Psyche, June, 1910) given a full descri|)tion of 

 A\isoniit, I prefer to use this name, although it appears on a later page of 

 Ashinead's pa|)er. 



I had at first placed the present species in UtibiOi-ytui Thorns., but 

 believe it is better placed as indicated above.
