Tetrastichus doteni, new species. 



Female. Length about 2 mm. Dark olive green, shining; the face 

 collapsing after death; antennae brown, joints of funicle subequal in 

 length, the first about as long as the pedicel; mesoscutum finely lineo- 

 lated, the lines mostly longitudinal; scutellum with similar but much 

 finer sculpture; parapsidal furrows very deep; median lobe of meso- 

 scutum with setigerous punctures, arranged in three more of less dis- 

 tinct rows along each lateral margin, the outer line near the parapsi- 

 dal furrow; disk of metanotum finely reticulately lineolated; median 

 groove of mesoscutum distinct; the pair of grooves on the scutellum 

 more distinct; median carina of propodeum developed into a broadened 

 plate, widening behind, its apex being the median portion of the apical 

 carina of the propodeum; on each side of this plate the surface is 

 sculptured to resemble faintly developed, thimble-like punctures; pre- 

 pectus lineolated; mesopleurae in part faintly lineolated, the rest 

 smooth, polished; metapleurae with sculpture similar to that on the 

 propodeum, but stronger; marginal vein not much longer than the sub- 

 marginal, stigmal less than half as long as marginal; coxae and femora 

 greenish, tibiae bark brown, with more or less metallic reflections; 

 knees, tips of tibiae, and the tarsi testaceous; last joint of tarsi dark; 

 abdomen longer than the head and thorax combined. 



Mate. Length about 1.25 mm. Similar to the female, but the tibse 

 with more testaceous; joints 2-4 of funicle subequal in length, the 

 first shorter; pedicel about as long as the second joint of funicle; 

 sculpture of propodeum more indistinct than in female. 



Habitat: Reno, Nevada. 



Type: Cat No. 14362, U. S. National Museum. 



From a series reared by Mr. S. B. Doten a type female and 

 a type male and five paratypes of each sex have been selected. 

 Mr. Doten writes that in cages the larva? of this parasite feed 

 readily on Habrobracon hebetor and on Mefaporus, and occa- 

 sionally on Pteromalus.
