REVISION OF SPECIES OF THE GENUS AGKOTIS. Ij5 



Noctua havilae Grt. 



1880. Grt., Bull. Geul. Siirv., \ i, I.'>7, v;ir. clainhatina. 

 l«8l. Grt., Papilio, i, 76, an sp. (list. 



1881. Butler, I'lipilio, i, 10l», an sp. <Ust. 



Very clo.sely allied to chindcstina in fjrouud color, shape of i)riinaries, 

 and indeed in {general liabitns. Distini^t by the gray, contrasting: 

 median lines which are much more strongly dentate and irregular, and 

 by the general grayish suffusion of primaries. The ordinary spots arc 

 less distinctly indicated, but are of the same general shape as cIuikIcs- 

 Una. The s. t. line is also much more evident, and tolerably even. 

 Secondaries darker, fuscous. Beneath darker, with the common line 

 and discal lunule distinct and complete. 



Expands 39-41 '"■", 1.5G-1.G4 inches. 



Habitat.— iSouthern California. 



This s[)ecies differs from clamleHtina in the grayish suffusion of pri- 

 maries and the darker secondaries. 



In addition, the 9 lacks the excavation at the sides of the penulti- 

 mate abdominal segment. Though closely allied, I believe the species 

 to be distinct. 



Noctua piscipellis Grt. 



1878. Grt., Can. Ent., x, 2:5:?. Aijrotis. 



Red brown, uniform in color; veins often black, transverse lines 

 usually wanting, when present punctiform ; s. t. line usually distinct, 

 pale, gray. Ordinary spots obsolete. The t. a. line is not so present as 

 to enable its course to be traced ; t. p. line evenly curved, the black 

 dots usually accompanied by pale, gray dots. Secondaries whitish, 

 smoky toward outer margin. Beneath whitish, powdered with reddish 

 toward apices; a distinct dusky common line, no discal spots. Tiiorax 

 concolorous; front deep blackish brown. 



Ex|).inds 35-40""", 1.40-1. GO inches. 



Habitat. — Colorado, Nevada, Arizona. 



A very distinct species. Usually the ]nimaries have the veins marketl 

 with black, and this is like the type, but specimens occur almost uni- 

 form brown, and in some the t. p. line is tolerably well indicated l)ut 

 always punctiform. The palpi are subequal ; the i)rimaries comi)ara- 

 tively narrow, outer margin rounded. 



Noctua atrifrous Grt. 



1873. Grf., Bull'. Bull., i, 97, .tfjrotis. 



1883. (Jrt., Trans. Kan.s. Ac. Sii.,viii, 17, .{(jrotis. 



dray with a reddish tint, veins somewhat marked with black scales, 

 ordinary spots obsolete; median lines often punctiform, unusually ap- 

 proximate; s. t, line very indefinite but traceable. T. a. line evenly
