Small and slender moths, the wings entire, black, the fringes partly white ; hind-wings 

 rounded, with nervure 8 running from the base, close to the subcostal nervure to beyond 

 the front angle of the discoidal cell ; antennae simple. The larvae are slender, resembling a 

 leaf-stalk, and undergo their transformations in a cocoon. 



* I. O. Atrata (Linn.), CJiarophyllala (Linn.), {Chinniey Sweep). — Wings black without markings ; 

 the fringes white at the tip of the fore-wings. Expands from i to ij inches. Common in most 

 parts of Europe and Western Asia in June and July. The larva is unicolorous green, and

 Size of Atrata. Inhabits the south of Central Europe, and some portions of North Germany, 

 in June and July. 



GENUS III. — MINOA (BOISD.). 



Fore-wings long and triangular ; all the wings entire ; the antennse of the male shortly 

 ciliated. The larva is short and thick, finely hairy, and undergoes its transformations in a loose 

 cocoon. The only species, * M. Murmata, Scop. (Eupliorbiata, W. V.), is pale unicolorous 

 yellowish-brown, and expands about three-quarters of an inch. It is common in a great part 

 of Europe, and in Northern and Central Asia, in May and June, and again in August and 

 September. The larva is dirty green, dotted with black and white, with a brown head. It 

 feeds on spurge in summer and autumn. The moth is figured at PI. 47, Fig. 14. 



GENUS IV. — STERRHA (HERR.-SCHAFF.). 



Rather small moths, the wings delicate and entire, the fore-wings broad and triangular, and 

 the hind-wings broad, pale, and without markings ; the antennae of the male pectinated. 



* I. S. Sacraria (Linn.). — Fore-wings sulphur-yellow, with an oblique purplish stripe running 

 from the tip to the middle of tiie inner margin ; hind-wings pale yellow or whitish. It varies 

 considerably, and has sometimes ochreous-yellow fore-wings, strongly dusted with brown, and a
