ApANTELES SARKOTHRIP^, Sp. 11. 



On June 30, 1884, there was noticed in a breeding cage, 

 at Normal, containing larvae of Sarrothripa lintneriana , a dead 

 larva in an imperfect cocoon, surrounded by cocoons of some 

 hymenopterous parasite. A few days later there emerged from 

 the latter six specimens of a well-marked Apan teles, for which 

 I propose the above name. Unfortunately the cocoons were 

 not saved, so that I am unable to describe them at this time. 



Imago. — Length 2.5 mm. 6, 9. Black; palpi white; labrum 

 and mandibles testaceous; antennae ferruginous; legs light red 

 except posterior coxae, which are black. Wings hyaline; tegulae 

 whitish; veins pale yellow except apical portion of costa which, 

 with the stigma, is testaceous. Lateral membranous margins of 

 terga of the three anterior segments, posterior portion of ter- 

 gum of third segment, and sides and ventrum of abdomen, 

 testaceous, lighter anteriorly. Dorsal portion of abdomen, ex- 

 cept the two anterior terga, piceo- testaceous. Mesonotum 

 shining, with distant, very shallow, punctures, many specimens 

 having a slightly depressed area on the posterior portion of 

 the mesoscutum, each side of the dorso- median line. Scutellum 

 of metathorax with punctures on its anterior portion, and 

 finely reticulated posteriorly; without median carina. Tergum 

 of first abdominal segment longer than wide, finely rugose, 

 narrowing behind. Tergum of second segment also finely ru- 

 gose, the wrinkles diverging obli({uely from the anterior mar- 

 gin: sides membranous. Terga of remaining segments smooth 

 and shining. Ovipositor concealed. Radial vein arising 

 slightly beyond the middle of the stigma. 



Described from six specimens (5 ?, 1 5) bred from a larva 

 of Sarrothripa liiitneriana. 



Much resembling A. cony rer/at lis and A. snierintJii, but 

 easily distinguished fromformer by its shining mesonotum, and 

 from latter by the rugose abdominal terga. 



Apanteles oknigis, sp. n. 



In the mines made by the larvie of the apple Ornix (0. 

 yeminafdla f Pack. ) in apple leaves, at Normal, there were found 

 March 21, 1880, many peculiar white, banded, cocoons of some 

 hymenopterous parasite. Between April 27 and May 10 there
