mentation of the primaries recalls E. caja. It is so unlike any of our other 

 species of the genus that further comparison is unnecessary. It is with 

 much pleasure that I dedicate this beautiful insect to Dr. H. C. Yarrow, the 

 surgeon and zoologist of this expedition, and to whom I am indebted for 

 many kindnesses. 



EPICALLIA, Hiibner. 

 EPICALLIA VIEGINALIS, Boisd. 

 Two specimens were received from Arizona similar to var. guttata, but 

 with rather more ochreous spots on the secondaries, and with the yellow spots 

 on the secondaries rather larger in size than in Californian specimens. 



MELANCHROIA. 

 MELANOHROIA? INCONSTANS, Hiibner. 



Melanchroia? inconstans, Walker, C. L., B. M., 389. 

 Ardonia secreta, Walker, C. L., B. M., 222, supp. 



One specimen from Arizona. 



ALYPIA, Hiibner. 



ALYPIA B1MACULATA, H. S. 

 Agarista Grotei, Boisd., Lep. Cal. (18GS-G9). 



One specimen in good condition from Arizona, with the secondaries 

 immaculate. The type of this species was from Mexico. 



GNOPHAELA. 



GNOPIIAELA HOPFFERI, Giote, var. DISCKETA Stretch. 



Var. DISCRETA, var. nov. 



Two specimens which I have referred to the above species may possibly 



prove to be specifically distinct, though I prefer at present to consider them 



merely as a local variety. While resembling G. Uopfferi in form, they are 



nearer to G. vcrmiculata, Grote, in color, particularly on the secondaries. 



The most prominent difference is in the yellowish spot of the primaries, 



which lies on the discal area, In vermiculata, this is cuneiform, and reaches 



nearly to the base of the wing ; in Hopfferi, it is quadrate, and does not 



extend back of the base of the fourth median nervule; while in discreta it is 



intermediate in form. These specimens were from Arizona, and neither of 



the previously described forms have yet been received from that Territory.
