narrowly rounded; phragma of the mesothorax has but slightly converg- 
ing sides and it reaches almost to the apex of the abdomen; ovipositor 
not protruded, and internally it reaches almost to the base of the abdo- 
men; thorax and abdomen together form an oval mass nearly twice as 
long as wide. 
Legs (Fig. 7b) of moderate length, the femora rather stout but 
compressed, the front tibiae also considerably enlarged; middle and hind 
tibiae and all the tarsi cylindrical and slender, the tarsi rather long 
although only three-jointed. 
Wings resembling a typical Mymarid wing in shape, being linear, about 
seven times longer than wide, and having an exceedingly long marginal 
fringe; venation reaching about to the middle of the costal margin, the 
submarginal and marginal veins about equal in length, the stigmal vein 
short and stubby, the postmarginal vein absent; costal cell extremely 
narrow; disk of wing on the apical half with a row of few fine, short 
setae; hind wing extremely narrow, yet rounded at apex. 
Male. Not known. 
Type of the genus: Megaphragma mymaripenne n. sp. 
Megaphragma differs from all other Trichogrammatidae 
known to me except Hydrophylax Matheson and Crosby in hav- 
ing the wings linear and very long-fringed. Hydrophylax, how- 
ever, has the thorax and abdomen combined about four times 
as long as wide, the legs considerably longer and slenderer, the 
antennae eight-jointed with two well-developed funicle joints 
besides an annellus, and with a comparatively small three-jointed 
club. In Girault’s classification Megaphragma falls in the tribe 
Lathromerim but differs from all the included genera with six- 
jointed antennae in having the wings very narrow and long- 
fringed. 
Megaphragma mymaripenne n. sp. Fig. 7. 
Antennae as in Fig. 7a, the middle joint of the club with two large 
setae and several smaller ones, the apical joint with one moderately 
long seta and with at least two of the chitinous sensoria projecting at 
apex. 
Disk of wing with about five or six very minute setae in an irregular 
median longitudinal row on the apical half beyond the venation; disk 
narrowest opposite the apical part of the marginal vein, somewhat widen- 
ing proximad and about twice as wide on apical half as at the narrowest 
point, the apex well rounded. Marginal vein with two fine, rather short 
setae at its base, and on the disk near the opposite margin just proximad 
of the constricted part is a somewhat longer seta. Marginal fringe
