tiiict bliick streak. Ordinary spots lar^a^, pale, with yellowish or 

 fuscous shading. Orbicular round, black ringed. Iteniforni kidney- 

 shaped, inwardly black marked, outwardly pale gray, its lower margin 

 touching the t. p. line. Clavitbrm coDColorous, not distinctly outlined 

 in any si)ecinieu 1 have seen, spanning the median si)ace. Secondaries 

 of S , whitish; of $ , fuscous. Beneath, powdery, with obsolete outer 

 dark line. Head and thorax concolorous with })rimaries ; collar with 

 a dark line. The harpes of 6 are broad at base, suddenly narrowed 

 from beneath to half their former width, then equal to the rounded tip, 

 which is inwardly fringed with tine spinules. Clasper rather long, 

 very stout and corneous, not greatly curved. 



Expands 29 to 32'""' (1.16 to 1.28 inches). 



Habitat. — Maine, New Jersey, Illinois, Nebraska, Colorado. 



Three specimens are in the Museum collection : Maine, New York 

 (J. B. S.). Tlie specimens dilfer in the amount of powdery appearance, 

 one of them quite smooth, almost glistening, the others rough. Easily 

 distinguished from the others in this group by the somewhat velvety 

 vestiture, the pale, outwardly somewhat indefinite reniform, and 

 strongly incurved t. p. line. Though placed here with lyensilis^ it would 

 seem more nearly allied to incurva of the laudabilis group but for the 

 shape of the genitalia. 



The species is quite widely distributed, and is, not unlikely, confused 

 with ricina in collections.

 marked. T. a. line even, outwardly oblique, with an inward bend be-

 variably distinct, sometimes obsolete, its course very irregular, always
