Body rather stout. Male abdomen long and slender, tip witn spreading 

 hairs. Head of moderate size. Palpi very long and slender, porrect, some- 

 times extending beyond the head by a distance as great, as the length of the 

 head; third joint nearly as long as the second. A pointed tuft of short hairs 

 between the palpi. Antenna' with unusually long pectinations, the tip sud- 

 denly simple. Fore wings acute, lip pointed and square, or a little rounded; 

 costa arched a little, slightly sinuous; outer edge convex, not angled. Hind 

 wings a little produced toward the apex, the outer edge not very convex. 

 slightly scalloped. Venation much as in Ematurga, but the subcostal venules 

 are much shorter, and there arc three subcostal veins instead' of two, the 

 second and third very short and equal in length There is no subcostal areole, 

 the first subcostal not joining its main vein again, as in Ematurga and Lozo- 

 gramma. The discal veins arc as in Ematurga. Hind legs very long and 

 slender; hind tibiae long, not swollen; tibiae as long as the tarsi. Coloration 

 light ochreous-gray, irrorated with brown, with a single incomplete extra- 

 discal line. 



These characters have been drawn up from S. juturnaria and the Eu- 

 ropean ericetaria. {jplnmarid) alone. The California!) species has more pointed 

 wings than the European, while the latter has very short palpi, but the pecti- 

 nations of the antenna? are twice as long as in the other species, and the hind 

 tibiae are shorter and thicker. It need not be confounded with Bupalus or 

 Fidonia, or its allied forms Ematurga, &c. It has the body of Lozograwma 

 and Thamnonoma, but differs from them in the plumose antenna'. The vena- 

 tion 1 do not regard as like Cymatophora (Boarmia), as stated by Lederer. 

 The species are of large size. 



Larva. — "Caterpillars cylindrical, neither attenuated nor carinated ; 

 without any tubercles; head globular; living ou low plants. Chrysalides 

 subterranean.'' — Gruen'e'e.
