CATALOGUE OF NOCTUID^E SMITH. 165 



The type in the British Museum has pointed wings, color and type 

 of maculation as in occult a, but with lengthily pectinated male anten- 

 na. I do not remember having seen the species previously. 



Genus POLIA Ochs. 

 1816. Octis., Sclniictt. Eur., iv, 73. 



Two quite distinct types are referred to this genus in our American 

 material. Whether they can remain associated is questionable, but 

 need not be decided here. 



P. aedoii Grt. 



1880. Grt., Can. Ent., xn, 154, 1'oliu. 



HABITAT. Colorado, in August; Nevada; Washington. 



A type is in the British Museum; another with Mr. Neumoegen. 



P. theodori Grt.* 



1878. Grt., Can. Eut., x, 235, Apntvla. 

 1880. Grt., Can. Ent,, xn, 219, Folia. 



1882. Grt., 111. Essay, 55, pi., n, f. 17, Folia. 



var. epichysis Grt. 

 1880. Grt., Can. Ent., xn, 219, Folia. 



1882. Grt., 111. Essay, 55, pi., n, f. 18, Folia. 



HABITAT. Colorado, August and September; New Mexico, Cali- 

 fornia'. 



Both types are in the British Museum. I have seen considerable 

 material of both forms and have no doubt of their relationship. Mr. 

 Hy. Edwards first suggested it to me some years ago. 



P. olorina Grt. 



1876. Grt,, Bull. Buff. Soc. Nat. Sci., in, 84, Hadcna. 



HABITAT. California ; Colorado. 



The type is in the British Museum; another specimen, also marked 

 "type," is in the Edwards collection. The species is allied to Polia 

 theodori and varies in the direction of suffusion with black. 



P. diversilineata Grt.* 



1877. Grt., Bull. Geol. Surv., in, 119, Hadena. 

 llh'pida Grt. 



1879. Grt,, Can. Ent., xi, 95, Folia. 



1883. Grt., Proc. Am. Phil. Soc., xxr, 156, Folia. 



HABITAT. New Mexico; Nevada; Colorado; Maniton in July. 



The type of diversilineata is a badly patched specimen covered with 

 mildew, in the Cambridge' collection. The type of ill&pida is in the 

 British Museum; others, labeled by Mr. Grote, but not marked type, 

 are in the National Museum. The two names refer to the same species.
