ASHMEAD : CLASSIFICATION OF THE CHALCID FLIES 291 



45. Hind tibi.T not compressed 48 



Hind tibiaj compressed. 



Pedicel not small, obconic;il, lar<;er than tlie lirst joint of the flagcUiun. V fjenus 



46. Eyes pubescent Macreupelmus Aslnnead. 



47. Postmarginal vein long, twice or nearly twice as long as the stigmal vein ; scape short ; llagclUim fil- 



iform, clothed with a dense pubescence ; pedicel minute. 



Joints 1-7 of funicle always longer than thick, the club-joints not very long. 



Cerambycobius Ashmead. 

 Joints of funiole very short, thicker than long, the chib-joints usually very long. 



Anastatus Motsehulsky. 



48. Hind tibise somewhat compressed. 



Pedicel obconic, smaller than the first joint of the funicle, the joints of tlie llagellnm, except some- 

 times 6 and 7, longer than thick ; dorsal abdominal segments not incised medially at apex. 



Arachnophaga Ashmead. 



Tribe II. Tanaostigmini. 

 This little group is allied to the subfamily Encijrtivn', in which groui) Dr. How- 

 ard first placed his genus Tanaodigma, and also to the family Cleonym'uhc, where, 

 deceived by a male specimen, I first placed the genus Entnchosoma. Additional 

 specimens, and the discovery of two new genera have enabled me to see more clearly 

 the affinities and relationship of the group to other chalcidids, and I believe other 

 discoveries will confirm my views in assigning it a position with the Eiipchmme 

 rather than with the Encyrtiviv.

Males '' 



2. Scape of antcnnie slender, not at all dilated 



Scape of antennae broadly dilated beneath, or dilated, or compressed its entire length. 



Scape compressed or dilated its entire length 



Scape broadly dilated beneath ; flagellum flattened, the joints of the funicle subpedunculate 

 and much wider than long; postmarginal vein shorter than the stigmal, the latter long; 

 postmarginal vein shorter than the stigmal, the latter long, nearly perpendicular with the 

 front margin ; abdomen not longer than the thorax, the ovipositor slightly exserted. 



Tanaostigma Howard (type T. cowsetiiv Howard). 



.S. Flagellum subclavate, the joints of the funicle cylindrical, a little longer than thick ; postmarginal vein 



about as long as the stigmal vein, the latter not short ; body bare ; abdomen as long as or a little longer 



than the head and thorax united Tanaostigmodes .Vshmeail (type T. howardli Ashm.). 



Flagellum subcompressed, the funicle joints, or at least 1 to :?, wider than long ; body well clotheil with 

 short, scale-like white hairs ; abdomen subglobose, scarcely as long as the thorax, the ovipositor 



subexserted Trichencyrtus Ashmead, gen. nov. (type T. chapadiv Ashm.). 



4. Body clothed with short scale-like white hairs ; scajie very slender, the flagellum stout, pubescent, the 

 joints wider than long ; wings glabrous, the stigmal vein ending in a knob, slightly curved anil as long
