REVISION or SPECIES OF THE GENTS AGIJOTIS. 53 



red brown color of the Aviiijj; the t. j). line is .seen to be single and 

 regularly iuterspaceally scalloped and accented on the nervule. Tlie 

 stigmata contrast by their gray color; the orbicular well sized, 

 spherical ; the renifonn proportionate and inclosing a blackish inferior 

 stain as in allied genera. The subterniinal line is <pute distinct, being- 

 indicated by a line of i)owdery grayish scales like the stigmata. There 

 is an extremely fine gray wavy terminal line he/ore the margin, formed 

 by the outer edging of the deeper tinted marginal line, which appears 

 as interspaceal points. Frlnf^es light brown, cut by a fine darker hair- 

 line ([)re<'eded by a pale line) without the niiddU^ Hind wings i)ale, 

 much soiled with fuscous and with the pale ruddy fringes. Be- 

 neath fuscous, with a rufous tinge, both wings rather dark, with 

 discal marks and a broad vague, common shade line. Thorax like 

 fore wings; collar above with indistinct pale edging ; palpal tips pale, 

 as is the front, else the head is rufous." 



Expands 32-34"""; 1.2S-1.3G inches. 



JIaiutat.— Canada, New Jersey, Northern and Eastern States. 



The color is variable, often irrorate with gray, otherwise there does 

 not seem much variation. 



The male harpes are gradually attenuate and rounded at ti[), the 

 clasper is stout, strong, single, almost rectangularly bent, and very 

 slightly curved. The species seems rare and has been recorded as 

 taken only in early spring (May). 



Genus PACHNOBIA On. 



Front smooth, rather broad, full ; anterior tibia sj^inose, somewhat 

 more heavily armed at tip. The vestiture is distinctly and lengthily 

 hairy, line; in sxlicariim- and ohdensls forming perceptil)le divided 

 anterior and posterior tnlts, in the other species loose,»divergent, or but 

 indefinitely bunched into a basal tuft. The S anteniuc are variable, 

 either simi)le, serrate or pectinate. The primaries also differ somewhat 

 in form, and this all'ords a basis for subdivision. The -? genitalia are de- 

 cidedly variable, in no two species exactly alike. From the other 

 groups, with smooth front and spinose fore tibia, this group is dis- 

 tinguished by the long hairy vestiture and the more or less ferruginous 

 color. The genus Pachuobia, as based on this group, is fairly well dis- 

 tinguished and should be accorded generic rank. Lederer says: Fore 

 tibia unarmed, head retracted, Iwmbyciform, habitus of Ta-nicampa, 

 with a sharp crest behind collar. None of the species agree with this 

 diagnosis, and whether the other species (except carnea), which Lederer 

 l)laces in the genus, agree with it or not is unknown to inc. I retain 

 the term, however, in the hope that it will prove available. The body 

 is plumj) in mlicaruni and oJiaJiensiSy but only moderately stout in the 

 balance of the species. The jnajority of the species have the $ 

 antenna strongly bipectinate.
