ORGILUS GELECHIAEVORA, new species. 



Related to maculiventris (Cresson) and differing principally as fol- 

 lows . 



Female. — Length, 3.5 mm.; ovipositor, 2.5 mm. 



Face granulariy opaque, scarcely a fourth wider than length of 

 eye; pronotum irregularly roughened; furrow of mesopleurum weakly 

 curved; metapleurum opaque coriaceous; propodeum irregularly, 

 transversely rugulose, with a distinct, medially interrupted apical 

 carina; apical abscissa of radius and intercubitus forming a nearly 

 straight line; stub of cubitus fully as long as second abscissa; nervulus 

 postfurcal by less than half its length; abdomen about as in meicu- 

 liventris; ovipositor shorter than body. 



Bright ferruginous; ocellar triangle not black; legs testaceous, tro- 

 chanters paler, tarsi and apices of hind femur and tibia fuscous; 

 wings very slightly infumate. 



Host. — Gelechia triaVoamaculella Chambers. 



Type locality. — Whitesbog, New Jersey. 



2>2>e.— Cat. No. 228G9, U.S.xV.M. 



One female reared July 12, 1916, under Quaintance No. 12789, by 

 H. B. Scammell. 



HABROBRACON GELECHIAE (Ashmead). 



Since my revision of this genus was published ^ I have reared a 

 large number of specimens of gelechiae from the grape berry moth. 

 These show variation from the broad abdomen of the type to the 

 tapering abdomen of joliannseni Viereck. They agree further w^ith 

 the type in the color of the legs and in the male in color of abdomen. 

 The last constitutes the only apparently constant character that I 

 have been able to discover, and were it not for this I would be 

 inclined to synonymize the two species. 



HABROBRACON ERUCARUM. new species. 



In my key to the North American species of Hahrohracon runs to 

 the last couplet, where it agrees in abdominal characters of the female 

 with gelechiae (Ashmead) and in color of male with joliannseni 

 Viereck. From both it differs in having the scutellum flattened and 

 subpolished, the propodeum with a median longitudinal carina at 

 apex, and in the ovipositor being only about as long as the second 

 tergite (in both gelechiae and johannseni the ovipositor is about twice 

 as long as the second tergite). The entire body is somewhat more 

 shining than in either of the other species, and the wings are less 

 distinctly clouded with darker venation.
