strong-, sometimes wanting. On the fore wings the accessory cell is 

 usually present, and ditferences are presented in the length and point 

 of origin of veins 7 to 9. But the neuration of all the genera is not 

 yet known. So far as my conclusions go we must, as yet, hesitate 

 to accord too great \alue to neurational characters in classifying the 

 moths as a whole. All characters must be used in classification, but 

 we are not in a position, e\i(.lently, to make the neuration the crucial 

 test. It is a general guide, but no more than a guide, to find the 

 most natural position for a genus; keeping it alone in sight we may 

 stray from the ends we propose to reach in arranging the objects of 

 our studies. 



Gen. AZENIA Grt. (1S82) 



Form very robust, like Spragucia, the wings long, primaries 

 widening a little outwardly. Eyes naked. Labial palpi closely 

 scaled, rather thick in appearance, a little longer than in Xanthoptera, 

 lying obliquely across the face, hardly exceeding the clypeal projec- 

 tion. This latter very large, overshadowing the infra-clypeal plate, 

 flattened, trilobed. Legs unarmed and thinly scaled. Two small, 

 yellow Western species, having the lacies of Xanthoptera. 



1. Azenia implora Grt., Papilio, ii, 1S6. 



Pale lemon-yellow; two ochrey dots in place of t. a. line. A 

 median ochrey shade band, irregular and faint; one or two dots in 

 place of t. p. line; minute points at base of the pale fringes. Hind 

 wings white. Beneath whitish; costa of fore wings a little clouded. 

 Head and thorax above like fore wings in color; the clypeal projec- 

 tion is distinctly tridentate. Abdomen pale, a little exceeding sec- 

 ondaries. 



Arizona. Type in coll. Neumoegen. 



2. Azeuia edentata Grt., Can. Ent. xv, 25. 



Dark yellow; fore wings with no apparent markings, except a 

 small costal dot; fringes concolorous. Hind wings fuscous. Beneath 

 yellowish; the fore wings darker shaded, and with a fuscous subter- 

 minal band. Thora.x and head above dark yellow. The clypeal 

 projection has its outer edge roundedly scalloped instead of forming 

 three pointed teeth as in implora. Size small, like implora. 



Arizona. Type in coll. Neumoegen. 



Gen. ESCARIA Grt. (1SS2) 



The wings are frail and rather wide, form like Eiistroiia {Ei-as- 

 trid), the body slender, with untufted abdomen. Eyes naked; labial
