Sactogaster anonialiventris. 

 Aslim. Can. Ent., xix. p. 130, 9 ; Cress. 8yn. Hym., p. 249 



S 9 . Length, 0.6 to l'""\ Black, shilling; the head finely, microscop- 

 ically punctate; antenna?! and legs black or brown-black; trochanters, 

 base of tibiie and anterior tibia' at tiji, and all tarsi paler or yellowish. 

 Tlie lateral ocelli are away from the margin of the eye; the basal three 

 club joints are transverse, the first the narrowest, last joint conical; 

 the parapsidal furrows are distinct posteriorly; the scutellum, nieta- 

 pleura and base of abdomen are covered with a silvery pubescence ; 

 the scutellura ends in an awl-shaped spine; wings hyaline; the inflated 

 second abdominal segment is as long as the tail. 



The S differs from the 9 in having an oval abdomen, which is shorter 

 than the thorax, and without the inflated second ventral segment; the 

 antenna! club is 4-J0iiited, the basal three joints being equal, quad- 

 rate, the funicle slender, while the thorax is subopaque from a faint, 

 microscopic j)unctuation. 



Habitat. — Jacksonville, Fla. 



Types in Ooll. Ashmead. 



Many specimens, Not rare in April in the flower of gall-berry {Ilex 



glabcr)^ and possibly a parasite on some (Jecidomyiid larvte inhabiting 



these flowers.

 littlti wrinkled ; anteunse and legs dark rufous, the middle and posterior 

 femora and tibia' at tips fuscous. Wings hyaline. Abdomen about twice 

 as long as the head and thorax united, the tail being about twice as 

 long as the inflated second segment; the apical lateral parts of the 

 fourth and the fifth segments wholly opaque, sculptured, otherwise the

Habitat. — Washington, D. C. 



Type in Coll. Ashmead. 



Dedicated to my friend, Mr. L. O. Howard, of the U. S. Department 

 of Agriculture. In the highly i)olislied surface, entire absence of parap- 

 sidal furrows, striated scutellum, the bare metapleura, and the long tail, 

 it is quite distinct from all other described forms in this peculiar genus.
