APPENDIX SS. 1859 



scarlet; thorax also blue, the same color as in C. Virginica Charp. ; patagise edged 

 with scarlet on inner margin ; abdomen same blue as thorax ; legs blue. Antennae 

 wanting. 



Upper surface, wings : Primaries black, with blue reflections, most noticeable at 

 basal part, which equals in luster the body ; secondaries shining blue. 



Primaries have the costa the greater part of its length from the base outward edged 

 with scarlet ; the submediannervule, the median nervure with its two middle blanches, 

 and the subcostal inferior nervule are also of the same fine scarlet or blood color ; fringe 

 white. 



Secondaries with white fringe, and without marks, as in other species. 



Under surface, color as above, but devoid of all the scarlet lines except that which 

 •edges the costa. 



Perhaps a better idea of the ornamentation of the primaries of this species can be 

 conveyed to those familiar with the North American fauna were I to state that the 

 arrangement of the scarlet lines is precisely the same as is that of the whitish-yellow 

 •ones in Yenosa. Of this, the most superb of all our species, one example, a female, was 

 taken July 16 at Rio Blanco. The antenna 3 , as above stated, were wanting, and the 

 secondaries were much torn and broken at the outer half, but the example had been 

 fresh when caught and was not at all rubbed : hence the description and accompany- 

 ing figure were accomplished without difficulty. 



Family BOMBYCIDJK. 



Genus CEOCOTA Hub. 

 Crocota Fragills, n. sp. 



Expands H inches; head and body ocher color above, inclining to flesh-color below ; 

 wings above ocher, a little inclining to pinkish near and at abdominal margin of sec- 

 ondaries; beneath, uniform flesh-color or pinkish. 



One example taken July 21 at Pagosa Springs. 



This species has the wings narrower and longer in proportion than any other I know 

 of, and throughout it is less robust in appearance.

Two males near headwaters of San Juan River August 2. One of these is like the 

 common European form; the other assimilates to var. Matronalis Fr. in the inner part 

 of secondaries being black. This is an exceedingly variable species. Some examples 

 (var. Hospita Seh.), found in Colorado and Europe, have the ground-color of wings 

 white ; others, the form common to Europe and Colorado, have the ground-color yellow ; 

 another form, so far known only from Europe, have the secondaries scarlet; yet 

 others in which the ground-color is black; this latter form is the following-cited 

 Eupsychoma Geametrica Grote. 



In the Trans. Am. Ent. Soc. iv. Grote and Robinson redescribed Plantaginis as new 

 under the name of Caispitis and Cichorii, adding that Cichorii would he readily distin- 

 guished by the black fringe and clear yellow bands of the upper surface of primaries. 

 The larva' of these two species are stated to be quite distinct, and to be found on differ- 

 ent food-plants. These authors evidently had little if any acquaintance with either 

 the European forms of this species, or with the habits of the larva- of the Arctians, as 

 the fringes in different European varieties of Plantaginis are either yellow, black, or 

 both, and the larvae of the Arctians, as any tyro knows, will feed on almost any green 

 thing, and in default of vegetable food will even sometimes devour each other.

August'2. one example taken near headwaters of the San Juan River, agrees exactly 

 with the figure in Proc. Ent. Soc, with the exception of having one more small white 

 mark near apex in primaries. 



This variety of Plantaginis was first placed by Grote in a new genus, Eupsychoma, 

 which he made for its reception. This genus he placed in the Zygamidce, To quote
