Descriptions of New Species of Heterocera. 



By R. H. Stretch. 



As many of the readers of "Entomologica Americana'' are aware, 

 I have for the past three years been engaged on a monograph of the 

 groups. Zygcc.nidoc, Lithonida and Arctiida of North America, intended to 

 collate all the literature thereon, and to illustrate all the species with a 

 good recognizable figure. The work is now in such a state, that its com- 

 pletion depends only on my ability to secure a certain number of types 

 for figuring; and in this place I propose, while describing certain new 

 forms, so as to obviate the risk of their being described while the work 

 is in the press, and so creating synonyms, to indicate my desiderata and 

 ask assistance from those who may be fortunate enough to possess the 

 species, either in the form of drawings or photographs, or the loan of 

 the insects themselves. At this date there are drawn about 350 figures, 

 illustrating 210 species, most of them already printed. 



Scepsis Wrightii. 9-cT- Similar to S.fulmcoUis, but smaller. Ik-ad, palpi, 

 antennae, legs, thorax and abdomen, black, the latter with blueish reflections. I'm 

 thorax white with very pale yellowish tinge, not extending to the underside of the 

 head and palpi. Primaries dark brown, as in fulvicollis, but with paler fringes and 

 yellowish costa. Secondaries diaphanous, with irregular blackish margin, as infulvi- 

 collis. Beneath as above. 



Expanse of wings 1.10 inches. Hab. Southern California, Wright. 



Described from 7 ^Q, received from Mr. G. W. Wright, after 

 whom it is named. Readily distinguished by its smaller size and the 

 tint and distribution of the prothorax coloring.
