two shade bands and discal mark. Expanse, 34 mil. One female. 

 Soda Springs, Cal. 



Cea. n. g. 



Allied in form, texture and vestitute to Trichocosviia. Eyes 

 naked, unlashed. Vestiture narrow — scaly. Form slight, weak, 

 tegument pale. Antennae simple. Colors pale, a little silky. 

 Front wide, rising to an embossed protuberance, around which the 

 short clypeal vestiture circles ; infra-clypeal plate distinct. Ocelli. 

 Labial palpi slender, rather weak, with elongate third joint. Ves- 

 titure not strongly adherent and not hairy. White, immaculate ; 

 fore wings very pale yellow. Tibiae unarmed. Legs v/eak, not 

 hairy. Abdomen very little exceeding hind wings, with dorsal 

 carina. Body untufted. Wings entire, rather broad and short ; 

 apices determinate, and outwardly the piimaries are full. 



Cea Immacula. n. s. 



Form of Calymnin. Thorax and primaries very pale yellow, 

 almost white, immaculate. Hind wings pure silky white above 

 and below, without marks. Body white. Arizona. Expanse, 27 

 mil. 



Agrotis Apposita, Grote. 



Fresh specimens from Soda Springs show that the body has 

 a purply tinge beneath reminding one of Lithophane. It belongs 

 to the group with unarmed fore tibiae. It may be known by its 

 purple-black wings shaded centrally with rusty-red and pale about 

 the median lines and with obsolete stigmata. Hind wings black- 

 ish fuscous. Expanse, 36 mil. 



Pyrophila Triquetra. n. s. 



Tibiae unarmed, vestiture mingled scales and hair ; eyes 

 naked, behind with very short lashes. Body sn^oth, somewhat 

 flattened. Labial palpi with small conical third article rather 

 short. Form of OrtJiodes, but distinguishable by the naked eyes. 

 Probably not to remain here, but sharing some of the structural 

 features of this genus. Dark fuscous ; the fore wings have three 

 unequal black marks, one above the other, preceding the subter- 

 minal line superiorly; the middle very small, the lowest the 

 largest. Lines and stigmata concolorous, marked with pale. 

 Hind wings and body paler fuscous. Beneath wings fuscous, 

 paler at base, with indications of exterior dark line and without 

 discal points. Body beneath yellowish. Palpi dark on the side 

 of second joint. Arizona. Expanse, 28 mil. The black marks 

 before s. t, line are vivid, and alone break the monotony of the 

 wings, which are of the dirty fuscous color of Agrotis CocJiranii, 

 H. Devastatrix and other ugly Noctuidae. It is a flattened, shiny 

 species, looking as if it lurked under bark, where I have found 

 Pyropliila and Agrotis Clandestina in abundance. This latter, 

 with Cupida, etc., should form a subgenus of Agrotis.
