scutum, tegulae, a spot beneath, spot on the sides of the pronotum, 

 anterior coxae and trochanters white; mesoscutum spot on the 

 scutellum, mesepisternum beneath, legs except dusky apices of the 

 posterior tibiae and the posterior tarsi rufo-ferruginous; wings 

 hyaline, iridescent, venation dark brown. 



Male. — ^Length, 5 mm. The punctm-ation of the male is sparser 

 than in the female; otherwise the structural characters of the above 

 apply well to this sex. Black; clypeus, mandibles, face, lower 

 posterior orbits, inner superior orbits, the usual spots on mesepi- 

 sternum extending back beyond the middle a spot on the 

 sides of the pronotum, oblique line on the mesepisternum, four 

 anterior coxae and trochanters white; legs ferruginous except the 

 dusky spot and the posterior trochanters above, the apices of the 

 hind tibiae and the posterior tarsi which are dusky; wings hyaline, 

 iridescent, venation pale brown. In the male the coloration of the 

 hind coxae varies from the usual ferruginous color through a piceous 

 spot to an entirely piceous coxae. 



Type locality. — Cheyenne, Mountains, Colorado. Described from 

 four females (one, type) and five males (one, allotype) recorded under 

 Bureau of Entomology, Hopk. U. S. Nos. 132836 (type) and 13295&, 

 material collected by J. H. Pollock and reared at the field station 

 at Ashland, Oregon where it was determined that this species is a 

 parasite in the cocoons of Evetria taxifoliella Busck. 



Type.— Ca.t. No. 20782, U.S.N.M. 



LISSONOTA DIORYCTBIAE, new species. 



The sculpture of this species is very similar to that of pleuralis 

 (Cresson) but the marking of the abdomen is quite different. All 

 the specimens of the species have the areolet incomplete, that is, the 

 second intercubitus obliterated. 



Female. — Length, 5 mm. Clypeus convex, shming the anterior 

 margin narrowly truncate; face and front coriaceous; mesoscutum 

 with close distinct punctures; propodeum with distinct separate 

 punctures, the apical carina well defined and promment; dorsal aspect 

 of the propodeum with a faint median, longitudinal impression which 

 is not however boimded by a carina; nervulus postf ureal at haK its 

 length; nervellus broken below the middle; tergites rather short and 

 coarsely sculptured, the first one-third longer than the second, 

 punctured basally, the apical margin irregularly rufous; second 

 subequal in length to the third, v/ith coarse, close punctures which 

 apically become confluent; the third has punctures uniform but a 

 little more separated than in the second; ovipositor almost as long 

 as body. Black; clj^peus, labrum, inner orbits, face except the median 

 line obscurely, the usual spots on the mesoscutum, the four anterior 

 coxae and trochanters white; mesoscutum, mesepisternum, meta-
