Described from one specimen reared, by O. Heidemann, from 

 the cocoon of a species of jMicaria. 



In the color of the abdomen and in having a distinct stump of 

 a cubital nervure, this species is distinct from all others in our 

 fauna, but otherwise it closely resembles H. drassi, described be 

 low. 



19. Hemiteles drassi Riley sp. n. 



Male. Length, 4.5 mm. Agrees with H. micarivora except as follows : 

 The face has no large punctations ; mandibles are piceous ; palpi white ; 

 dorsulum of postscutellum closely punctate; not striate ; posterior tibise 

 and tarsi fuscous; the second and third abdominal segments and the ex 

 treme apex of petiole and base of fourth segment are rufous ; the rest of the 

 abdomen black; while the discoidal nervure is simple and not broken by 

 a stump of a cubital nervure. 



Hab. Columbus, Ohio. 



Described from two male specimens reared, by F. M. Webster, 

 from cocoons of a Drassid spider. 



The three species of Hemiteles above described by Mr. How 

 ard's desire occur, unfortunately, in the male sex only, and on 

 account of the divergence which often occurs between the two 

 sexes in this genus it will be difficult to connect the females with 

 them until they have been reared together. It seems desirable, 

 however, to characterize the species in this connection, even 

 though the characterization be necessarily incomplete. [C.

20. Eupelmus piceus Riley sp. n. 



Female. Length, 3.1 mm. ; ovipositor, o.Somm. ; width of head, i mm. 

 ^Eneous-black, with bronzy and metallic reflections. Head and thorax 

 above (except the mesonotal depression, which is smooth and shining) 

 finely shagreened ; lower part of face and cheeks metallic green, the cheeks 

 below the eye finely striolate ; trochanters, anterior and middle femora, 

 tibise and tarsi beneath, posterior femora at tip and the ovipositor, ferrugi 

 nous ; femora and posterior coxae with a metallic aeneous tinge, the latter 

 with some silvery-white hairs, while the rest of the legs are blackish. 

 Wings hyaline, with a large, fuliginous discal blotch below the marginal 

 nervure; tegulse large, dull fuscous; mesopleura blue-black, finely and 

 longitudinally aciculate toward posterior margin. Head very broad, wider 

 than the thorax across the wings, fully three times as wide as long antero- 

 posteriorly, the occipital region broad, slightly and roundedly emarginate ; 

 ocelli triangularly arranged, face broad, flat, without a trace of the anten- 

 nal furrow; eyes large, elliptic, divergent anteriorly, the face, in conse 

 quence, being wider below than above ; anterior edge of clypeus and the 

 mandibles ferruginous; palpi blackish. Antennae widely separated at 

 base, inserted just above the clypeus, slender, the flagellum about twice
