Larni. — " Kather short, a little Ila1tcn<'d, >velvcty green, with the ventral 

 region white or glaucous: head small and globular; living exposed on trees.

It is singidar how constantly E. cambricaria has l)een separated gen- 

 crically from E. dilu/ata; tliough, according to Lederer, it was regarded l)y 

 Standfuss as a variety of E. dUututa. Why Curtis separated it from ''Ojiora- 

 bia'' does not seem plain, as lie remarks that "it is doubtful whetlier it may 

 not be necessary to remove Opornhla to the genus before us." He then 

 compares E. (liis Venusi(i) camhrica with E. diluiata and E. maUistrigariu. E. 

 cambricaria is so close to E. dilutata that I had regarded it as a variety of 

 that species, and referred to it under that name in Hayden's Report for 1874. 



There seems no good reason why Hiibner's name Ejnrrita should not be 

 restored, though lu; ignored it in his Verzeichniss and used Oporin'ui instead.

Very small, with broad, iliil'use lines, or, when a little rubbefl, aboutFtwelve lineson the foro 



wings ; four lines on umlcr side of hind wings E. peiiincata.

5 <?, 5 9. — Closely resembling, in size, shape, and markings of wings, 

 E. \2-/int'afa. The head is whitish-gray above, in front dark-brown; 

 the palpi brown at tips above. Antennae simple. The fore wings are 

 white, crossed by numerous wavy, tine lines, about twelve in number. It 

 differs chiefly from E. Vl-lbieata, however, in the median line ])eing much 

 broader and more distinct, and with a brcxid ochreous shade between it and 

 the'line beyond. The hind wings are whit(\ with the scalloped lines on the
