DIOCTES. 473 



antennae are much shorter and the abdomen apically broader than 

 in the present female. It is smaller, with the terebra shorter, 

 than D. aryenteopilosa. 



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

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

 pair in Ceylon in 1873, and Green bred one at Peradeniya from 

 the case of an undetermined Psychid moth. 



366. Dioctes debilis, sp. n. 



$ . A small black species with somewhat dense silvery pubes- 

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

 metanotal areola not longer than broad. 



Lenytli 4 millim. 



CENTRAL PROVINCES : Nagpur ; BOMBAY : Surat. 



Type in the Pusa collection. 



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

 having the scape almost entirely stramineous, the flagellum very 

 distinctly red beneath, the areola not longer than broad and 

 emitting its costulaj from the exact centre, second segment 

 laterally and apically ochraceous, with the fourth, fifth, and sixth 

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

 half of the hind ones blackish only below, base of the hind tibia3 

 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 was bred from the Ptero- 

 phorid moth, Exelastis atomosa, "Wlsm., at Snrat, and the second 

 specimen from another Pterophorid, Splienarches caffer, Zell. The 

 cocoon is white and hairy, 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 apically rounded ; the large mandibles, 

 except apically, and the palpi rufescent ; labrum broad and 

 prominent. Antennas, : scape bright and conspicuous red, with a 

 black discal line. Thorax closely and somewhat strongly punctate; 

 metathorax dull and scabrously punctate, with the basal area 

 transverse and inconspicuous; areola subparallel-sided, longer than 

 broad and apically emarginate, with its basal angles rounded and 

 strong costulae emitted near base ; petiolar ai*ea subquadrate, with 

 complete carinse and subexcavate, with only its apex subdiscrete ; 

 spiracles small and exactly circular. Scutellum prominent and
