DIOCTES. 473 



aiiteimae are much shorter and the abdomen apieally broader than 

 in the present female. It is smaller, with the terebra shoi'ter, 

 than D. anienteopilosa. 



D. vulgaris must be extremely abundant in Bengal, whence I 

 have seen more than a score of specimens. Ur. Thwaites found a 

 pair in Ceylon in ISTo, and Green bred one at Peradeniya from 

 the case of an undetermined Psychid moth.

2 . A small black species with somewhat dense silver}'- pubes- 

 cence, the legs almost entirely and most of the abdomen red : 

 metanotal areola not longer than broad. 



Length 4 millim. 



Central Protinces : jS'agpur ; Bombay : Surat. 



Type in the Pusa collection. 



Extremely like small specimens of D. vulgaris, but differing in 

 having the scape almost entirely stramineous, the tiagellum very 

 distinctly red beneath, the areola not longer than broad and 

 emitting its costula? from the exact centre, second segment 

 laterally and apieally ochraceous, with the fourth, tifth, and sixth 

 discally blackish, all the coxte clear stramineous, with the basal 

 half of the hind ones blackish only below, base of the hind tibiie 

 but not of their femora blackish. 



I have seen two females in the Pusa collection, which I am 

 satisfied are distinct from D. vulgaris, if only on the evidence of 

 their metanotal structure. The type Mas bred from the Ptero- 

 phorid moth, Eccdastis atomosa, AVlsm., at Siarat, and the second 

 specimen from another Pterophorid, Splienarches caffcr, Zell. The 

 cocoon is white and haiiy, 5 millim. in length, and the imago had 

 emerged from an irregularly circular hole, distinctly before its 

 apex.

2 . A black species, with dense and somewhat long silvery 

 pubescence. Head closely and rather strongly punctate, with the 

 clypeus not discrete and apieally rounded ; the large mandibles, 

 except apieally, and the palpi rufescent ; labrum broad and

 metathorax dull and scabrously punctate, with the basal area 

 transverse and inconspicuous; areola subparallf 1-sided, longer than 

 broad and apieally emarginate, with its basal angles rounded and 

 strong costulic emitted near base ; petiolar area subquadrate, with 

 complete carinte and subexcavate, with only its apex subdiscrete; 

 spiracles small and exactly circular. Scutellum prominent and
