bolandcri was taken at Mt. Shasta, California ; but my specimens, 

 agreeing very well, are from Montana. The larva is quite distinct. 

 Black, dorsal band vermilion red, pale in the incisures; segments 

 white dotted posteriorly ; wart iii bright red at base, the subventral 

 warts pale. Hair stiff, reddish subventrally. I have given the full life 

 history in Proceedings of the Boston Society of Natural History, 

 Vol. XXVI, page 153 (1S93). 



23. Proxima is a distinct form inhabiting the arid region. I have 

 taken it at Salt Lake City and it is very abundant in southern Cali- 

 fornia. The sexes are quite dissimilar in appearance, on account of 

 the different color of the hind wings. The species extends into 

 Mexico. I would request collectors not to present specimens of this 

 species to the National Museum, as we have them already by the 

 drawer full. 



The larva is black with a series of dorsal red spots, one on a seg- 

 ment, each pointed before ; the hair is black, mixed with brown. I 

 have described the life history (Ent. Amer. , VI, 117) and the Na- 

 tional Museum has a dozen blown larva; prepared by Mr. Koebele at 

 Los Angeles, California, and Ogden, Utah. It will not be necessary 

 for you to waste much time on this common species ; but if eggs come 

 to hand, fuller obser\ations may be made on stage I than I was able to 

 make at the time I bred the species. 



Finally I would call your attention to a few structural points that 

 will assist in separating the larva; of Eiiprepia. As these are not 

 generally given in descriptions I have been unable to use them, ex- 

 cept in the few larvi^ that are actually before me. These points re- 

 late to the size of wart i, the presence or absence of a shining base to 

 wart ii and the distinctness of the barbules of the hairs. Eight species 

 that are before me separate as follows, which will illustrate the way in 

 which I suggest that these characters be used. 



Paiiial synoptic table op /nrvic op Ettprepia. 



Wart i large, about half the size of wart ii; wart ii with shining base. 

 Hairs barbuled, distinctly cleft under the lens. 

 No dorsal line. 



Hair partly red virgo. 



Hair all black anna. 



A broken white dorsal line superba. 



Hairs smoother, only the shorter ones distinctly cleft proxima. 



Wart i smaller, about one-third the size of wart ii; wart ii with shining base.
