This species, which has been reared in great numbers from 

 the larva of the pink boll worm, by August Busck, is, as far as 

 can be made out from the literature, still undescribed. It is 

 apparently very closely allied to distinguinda Kieffer (= cellu- 

 laris Kieffer not Say) and is the same as the species recorded 

 under that name in Proc. U. S. Nat. Mus., vol. 41, 1912, p. 

 448. Compared with Kieffer's description of distinguinda (as 

 celltdaris Say, Berl. Ent. Zeitscher., vol. 50, 105, p. 254) the 

 following differences are noted : Third antennal joint not 

 longer than wide ; apical joints of antennae blackish ; four pos- 

 terior tibiae mostly black; wing veins very pale brown. From 

 the other bethylid parasite of the pink boll worm, Perisierola 

 nigrifemur (Ashmead), it may be distinguished by the relation 

 of the ocelli to each other. In Kieffer's key (Das Tierreich, p. 

 533) it runs to cellularis Say. 



Female. — Length 2 mm. Head nearly as wide as the thorax, 

 finely coriaceous and with a few large scattered punctures ; 

 ocelli in a low triangle ; posterior ocelli less than their width 

 from the occiput ; interocellar line more than half as long as 

 postocellar line ; clypeal carina strong, complete : scape a trifle 

 longer than second and third joints combined; second joint one- 

 third longer than apical width; third and following joints as 

 long as their apical width ; pronotum narrowed anteriorly ; tho- 

 rax shining, with very fine reticulations; dorsal aspect of pro- 

 podeum shining; posterior aspect shining or finely reticulate 

 and with a faint median furrow; stigma truncate apically, but 

 a very little longer than the parastigma. Black; flagellum ex- 

 cept apical four joints, trochanters, and tarsi ferruginous ; tibiae 

 brown, ferruginous at base ; wings hyaline, stigma and para- 

 stigma dark brown, venation yellowish. 



Male. — Length 1.5 mm. Differs from female in being more 

 shining and in the black tibiae and rather yellowish tarsi. 



Honolulu, Hawaii. Described from eleven (one type) fe- 

 males and two (one allotype) males which were reared by Aug- 

 ust Busck as a parasite of the larva of Gelechia gossypiella and
