partJienice comes very near anna. In fact, it has been suggested that 

 ainm was only a form of partlienicc. Anna has yellow hind wings 

 and a much greater tendency to melanism ; but the pattern of the fore 

 wings is almost identical. Thus partlicnice is a central form with 

 close allies on all sides, leading through recti It nea lo phxilira and the 

 group without linings on the veins, and through anna to ornata and 

 the western species. 



The larva has been described by Saunders as black, with a flesh- 

 colored dorsal stripe and yellowish warts and feet ; but this was many 

 years ago, and the observation has not been verified. Larvre, which 

 I have had from eggs oi parthenice, did not agree with this description, 

 but were almost absolutely indistinguishable from those of vifgo. 

 They were, however, much smaller and hibernated in the fourth or 

 fifth stage, less than half grown; width of head .9 or 1.25 mm. I 

 have not seen the mature larva, and it is possible that it may agree 

 with Saunders' description, though I fear that this'is unlikely, as it 

 is not customary for the dorsal line to reappear after it is once lost. 

 The process is usually the reverse. 



11. Anna is really the variety, being the rarer and aberrant 

 form o( pc/stp/ione ; but the name was puljlished earlier. The second- 

 aries are yellow with a strong tendency to melanism. In my 12 

 specimens, none have the outer black border broken through, and one 

 has the wings wholly black. The fore wings are like pafthenice, but 

 the longitudinal bands are occasionally very heavy and the submedian 

 stripe usually runs closer to the median vein. The species is, un- 

 doubtedly a good one, though very near to partlienice. It inhabits 

 the dry oak woods of Long Island and New Jersey, extending well 

 south, but also into northern New York, Missouri, Nebraska, Iowa 

 and Wisconsin. It is never very common, though well distributed 

 in its wide range. The moths appear in June, and I think there is 

 but one annual generation. The larva is entirely deep black, with 

 shining warts and stiff black hairs, alike in color throughout. I have 

 described the life history up to hibernation (Psyche, viii, 53) which 

 seems to occur in the last larval stage. This point is not certain, and 

 hibernated larvae should be looked for in April or May, and the 

 heads measured to determine whether there is any moult in the Spring. 



12. Oithona (^rectilinea')^ is a puzzling form. We naturally 



* Oithona Streck. is an aberrant form of rectilinea French, as I learn from an 

 examination of Dr. Strecker's type.
