REVISION OP SPKCIKS OF THE GENUS AOROTIS. 121 



Feltia aeneipeuuis Git. 

 187G. Grt., Biift". Bull, in, 81, Ayrotin. 



Leather brown, with all inaculatioii snbohsolotc; but so lar as trace- 

 able it is the same as in vancouverensis. The claviforin, however, is 

 barely traxHMble, and never Ibrnis a proiiiineiit feature in the specimen. 

 Tlie thoracic vestitiire is somewhat less even and looser, l)iit else 1 (;an 

 find no distinctive fejiture, except the form of aiitennse to separate this 

 species. The joints of the $ antenna, as com[)ared with that of semi- 

 clarata, are broader, shorter, serrate on both sides, the serrations 

 longer. The S genitalia are exactly as in ftemiclarata. 



Expands ."iT""" ; 1.50 inches. 



Habitat. — California; Washington. 



The great majority of specimens ot acncipennis that are found in col- 

 lections are really pale forms of rajieouvcrcnsis, and Mr. Grote himself 

 never was quite sure of the limits of this species or of the forms he called 

 vancotiverensis aud semiclarata ; nor indeed could he be so without closer 

 comparison between them than could be made between single vspeci- 

 mens, superficially examined. 



The National Museum collection contains a long series of specimens 

 which I refer to tins species. Many of them are bred, as are also many 

 s[)ecimens of vancoun'ren.sis. "When the larv;c of these species are de- 

 scribed and the bred series closely studied, other characters may be 

 found rendering separation more easy.

Varies in ground color from light reddish gray to dark blackish 

 brown, (;ostal region always darker, varying from reddish to black 

 brown; the t. a. line is usually distinct, single, beginning on costa un- 

 usually distant from base, slightly irregular, and inirardlij obli(]ue to 

 internal (submedian) vein, then with a wide outward curve to inner 

 margin: the line is most obvious in dark specinieus. T. j). line often ob- 

 solete more obvious in pale specimens, crenulate, and with a single 

 even outward curve. S. t. line obsolete or very narrow, i)ale, very 

 close to the outer margin, and very strongly and irregularly dentate, 

 some of the teeth touching the outer margin; claviform always dis- 

 tinct, outlined, but rarely lilled with black; onlinary spots narrowly 

 ontlineil with black; orbicular usually more or less distinctly ovate; a 

 narrow black dash between the spots and an outward sagittate black 

 <lash from miildle of outer side of reniform, sonu'times meeting a sagit- 

 tate dash from one of the long dentations of the s. t. line. Secondaries 

 pale to dark fuscous; beneath, powdery with a more or less evident 

 common line and discal lunule. Jlead and thorax of the color of i)alest 

 part of pi imaries.
