Missoula, Montana. Described from one male and one female 

 recorded under Bureau of Entomology Number Hopk. U. S. 11526. 

 Material collected January, 1913, and reared by Joseph Brunner, 

 for whom the species is named. The female is the type. 



Type: Cat. No. 16032, U.S.N.M. 



Itoplectis plesia, n. sp. 



Judging from the description this resembles Pimpla behrensi 

 Cresson, but may be separated from that by the shorter ovipositor 

 and in not having the apical margin of the tergites yellow. 



Female. Length, 9 mm.; length of ovipositor 5 mm. Apical margin of 

 the clypeus straight; front with the distinct, well defined, separate punc- 

 tures, which become more widely separated towards the inner margins of 

 the eyes; seen from the side, the entire front is gently convex; the antennal 

 fovese sharply defined below; area immediately below and between the an- 

 tennae depressed into a V-shaped fovea, the apex of the V being ventral; 

 the distance between the eyes at the vertex slightly less than the distance 

 between them at the clypeus ; the emargination is broad ; head above the an- 

 tennae and the posterior orbits shining, practically impunctate, straight 

 above the inner bases of the antennae; ocellocular line subequal with the 

 width of the lateral ocellus; third antennal joint but little shorter than the 

 fourth and fifth combined; mesoscutum shining with widely separated 

 setigerous punctures; mesepisternum similarly sculptured; scutellum and 

 propodeum similarly sculptured; dorsal aspect of the propodeum with two 

 well defined diverging carinse which extend to where the sloping posterior 

 face begins; first tergite with sparse well defined punctures except the me- 

 dian apical area which is practically impunctate; the second tergite with 

 large, sometimes confluent punctures except the apical margin which is 

 practically impunctate; basal margin with two elongate fovese, just before 

 the apical margin depressed, the depression broader laterally; the third 

 tergite similar to the second except there is no fovea basally; the fourth 

 tergite similar to the third but not quite so densely punctured ; the fifth and 

 following tergites with sparse punctures. Black; tegulae white; legs below 

 the coxae rufo-ferruginous; the intermediate tibiae annulated at the base 

 with black, and below the black annulation is awhiteannulation; posterior 

 tibiae and tarsi black, the tibiae with a white annulation at the basal third, 

 the base of the first and second tarsal joints white; calcaria white; the 

 intermediate tarsi have the two basal joints white at the base; wings hyaline 

 iridescent, venation black.
