246 Eev. T. A. Marshall's mojiograph of 



hind coxfe, apex of their femora, their tibiae at both ends, and their 

 tarsi, black ; 4 anterior tarsi blackish at the tips. Wings hyaline, 

 somewhat dusky at the tips; squamulae testaceous, with a brown 

 spot ; stigma and nervures dark fuscous. Antennae entkely black, 

 longer than the body. Moderately shining ; head and mesothorax 

 very finely, scutellum and metathorax more strongly, pimctulate, 

 the latter smooth at the apex, and indistinctly bisected by a longi- 

 tudinal impression. Abdomen shining ; segment 1 a little longer 

 than broad, with parallel sides, rounded behind, smooth except a 

 few punctures ; 2 as long as 3, punctate, with two longitudinal 

 channels, between which is an obtuse cariniform elevation ; suturi- 

 form articulation bent, concave posteriorly ; segment 3 sometimes 

 with a few punctures. Hind coxae large, punctulate. Terebra sub- 

 exserted. Valvula ventralis not surpassing the anus. Spurs of 

 hind tibiae whitish, longer than ^ the metatarsus. ^ ? . Length, 

 If ; wings, 4 lin. 



Var. 5 . Anterior coxae blackish at the base. — Ruthe. 



Described from two males and one female. The male 

 has longer antenna) and a more slender abdomen. Hali- 

 day's description of calccatiis agrees with that of jJ!(?>('sc't'HS 

 by Euthe much better than with that of marciinatus, to 

 which it is assigned by Reinhard. Thus Haliday gives 

 the antennfG as entirely black, and says nothing of a 

 carina on the metathorax, as he certainly would have 

 done in speaking of margmatiis. He describes the wings 

 as dusky at the apex, which is true of this species, but 

 hardly of viarginatus. The three specimens have the 

 canaliculated metathorax, and are undoubtedly imhe- 

 scens, Ratz. ; one of them has also been verified by 

 Eeinhard. 



A ? was bred by Eatzeburg from a young larva of 

 Ocneria dispar, L., and sent to Euthe. In England 

 Eaynor has obtained the ? at Brandon, June 16th, from 

 Thcra rariata, Schiff. ; and Bignell the <? from the same 

 victim, Juno 24th. The second <? was reared by Bignell 

 from Lohoplwra carjyinata, Bork., April 10th. Cocoons 

 straw-coloured, or dirty yellowish white. Bignell's 

 specimen from Lohopliora is accompanied by a dark 

 brown cocoon, lighter in the middle, and apparently 

 belonging to an Ophionid.
