harctia Isabella. We have never seen any larvae of tin's species that could 

 be mistaken for that of assimilans, var. fraiiconia Slosson. The larv;e 

 of the latter species is more slender, light yellowish white or straw color, 

 with rather long soft bristles of the same color as the body, and lacks the 

 usual dark shade found on the anterior segments of fnliginosa. 



Assimilans var. franconia Slosson ? Rare. Whether this is var. fraii- 

 conia or an undescribed species we do not know, we are very sure it is 

 notfuliginosa, but have never seen an authentic specimen of franconia, 

 and while it does not just agree with Mrs. Slosson's description and figure 

 it comes very near it. 



The larva was found feeding on the flowers of the common thorough- 

 wort. It is pale yellow, thickly covered with rather long soft light yellow 

 hair. It looks almost exactly like the larvae of Cycnia oregonensis and 

 would be taken for it. The moth came out in July. 



SPILOSOMA. 



Virginica Fb. Common during most of the summer. 



Prima Sloss. Rare. June. Larvae black with a narrow pale yellow 

 dorsal line, and covered with rather long stiff" black bristles. Feeds on 

 grass and passes the winter in the pupa state. 



Antigone Strecker. Rare. June. 



CALLARCTIA. 



Virgo Linn. Common. July and August. The hibernating larvae are 

 black, and covered with stiff black bristles ; when found in early spring, 

 after moulting, the bristles become reddish brown with those on the 

 dorsal part of the last four segments quite dark, nearly black. 



Virguncula Kirby. Rare. June and July. The larvae hibernate and 

 are black, covered with rather long black bristles with a reddish shade 

 on the sides. 



Parthcnice Kirby. Common. July to September. We have had a 

 large number of the larva of this species and A. virgo, and cannot sepa- 

 rate them, as there is no difference except in size, and even this won't work 

 with a small virgo and large parthenice. There may be a difference in 

 the early stages, we have not had any parthenice larvae during the first 

 two stages, hibernating larvae of virgo being black. 



Anna var. persephone Grt. Rare, May and June. We have never 

 seen the larvae of this specie-;. 



MIMARCTIA. 



Argcz Dru. Common. Two broods. May and August. 



CYMBALOPHORA. 



I'hvllira Dru. Rare. May and June. This species shows great vari- 

 tion, scarcely two specimens being just alike. The larva? on their moult 

 are jet black thickly covered with stiff black bristles.
