breadth, narrowed towards the apex, forming an elongate triangle, 

 rugnlose ; segment 2 a little shorter than 3, transverse, with two 

 impressed lines converging forwards, and enclosing a triangular 

 space ; the other segments smooth. Terebra very short. ^ ? . 

 Length, 1^ ; wings, 3^ lin. 



This species looks very \\\q fulripes, Hal., from which 

 it may be known by the form of the 1st segment, and by 

 the rugose metathorax, bisected by a longitudinal carina. 

 In fiilnpes the 1st segment is more than three times as 

 long as its medial breadth, and the metathorax smooth, or 

 nearly so, without a longitudinal carina. Some specimens 

 oi imlUdipes have the legs slightly varied with fuscous. 



Abundant ; attacking almost exclusively the larvae of 

 the genus Pliisid ; though, if there be no mistake, Brischke 

 at iJanzig has also obtained it from Spilodes verticalis, L., 

 Cuctdlia avficjitea, Hufn., and Vcoiessa iirticcE, L. 



Bignell has bred series from Phisia gamma, L. ; one 

 of these broods remained 32 days in pupa, hatching out 

 Oct. 16th ; another set, bred by W. H. B. Fletcher, came 

 forth August 9th; another, bred by J. E. Fletcher, on 

 September 30th ; Piogenhofer at Vienna, according to 

 Reinhard, has reared it from the same. Also obtained 

 by Bignell from Plnsia iota, L., and P. chrysitis, L. 

 Numerous examples are in Fitch's collection, bred by 

 him from Pliisia gmnma, and by Meldola from P. iota, L. 

 Goureau bred 24, on August 23rd, from the white agglo- 

 merated cocoons surrounding a larva of Plusiafestucce, L., 

 collected on August 9th (Ann. Soc.Fr. (2), iii., 361 ; 1845). 

 Cocoons white, enclosed by the gregarious maggots in an 

 oval ball of flocculent texture, as large as a pigeon's egg ; 

 resembling the nest of congestus, N., except that the latter 

 is smaller and yellow.
