Not uncommon, but the notices of its occurrence are 

 mostly doubtful, owing to its having been confused with 

 M. deceptor. Described here from four females and one 

 male in Fitch's collection, taken by him, Bridgman, and 

 Bignell in their respective districts ; found also by 

 Billups at Peckham, and by me in Yorkshire. Bignell 

 bred the ? from Odontoptera bidentata, Clerck, and 

 S. v. Vollenhoven reported the rearing of another at the 

 Hague from Ileterogcnea limacodes, Hum. According to 

 Ratzeburg it was bred by Brischke from Rhodophcea 

 suavella, Zinck. The cocoon is not noticed, but probably 

 resembles that of M. deceptor.

J . Rufo-testaceous ; eyes during life green ; antennae towards 

 the tips, claws, and valves of the terebra, fuscous ; hind tarsi 

 testaceous. $. Nigro-piceous ; base of the antennae, face, orbits, 

 scutellum, abdominal segments 2-3, or more, and legs, rufo- 

 testaceous ; hind femora infuscated, their tibiae blackish except at 

 the base, their tarsi rufo-testaceous. Wings of the ? testaceo- 

 hyaline, squamuhe and stigma luteous, nervures fusco-testaceous ; 

 of the $ fusco-hyaline, nervures and stigma fuscous ; praebrachial 

 areolet of the fore wings shorter than, sometimes as long as, the 

 pobrachial, but never longer; recurrent nervure rejected; radial 

 areolet of the hind wings not divided. Terebra as long as half the 

 abdomen. $ ? . Length, 3— H ; wings, 5-J— Ci lin: 



Var. $ . Coloured like the <? , only the abdomen after the 1st 

 segment is entirely testaceous. Eeinhard. 



The $ strongly resembles that of sp. 1, and must be distinguished 

 by the hind wings. The discrimination of both sexes from cliry- 

 soplithalmus is less easy, inasmuch as the few differences that 

 exist are liable to exceptions. The recurrent nervure, however, is 

 always rejected, and the praebrachial areolet never longer than the 

 pobrachial. The present species is somewhat smaller, the $ more 

 darkly coloured, especially as to the hind tibia?, and the terebra of 

 the 2 shorter. Antennae longer than the body, setaceous, those of 

 the cf 38 — 44-, of the ? 35 — 40-jointed. Vertex and occiput of the 

 J sometimes infuscated; mandibles dark at the tips; petiole of 

 the 1st segment occasionally fuscous at the base ; abdomen obliquely 

 truncated at the apex ; tarsi a little paler towards the tips. The
