peared without ni)' learning the cause, though I attributed it 

 to a pair of daddy-long-legs {Phalangidea), which were, by 

 accident, imprisoned with the larvae. From the larvae reared 

 indoors I obtained in November and December ten males and 

 four females. No attempt was made to breed from them as it 

 was out of season. The higher and more even temperatures of 

 the house doubtless accounted for their maturing in the autumn 

 instead of hibernating as is their wont. In this series of four- 

 teen moths, presumably from the same parents, the range of 

 variation was distinctly narrower than in the series bred from 

 larvae taken at large. The only wide departure from the usual 

 co?ifnsa form was one male, in which the median white spot on 

 primaries was split up into a group of three oval spots. A 

 tendency toward this subdivision of the median spot was shown 

 by two other specimens. 



This series seemed to support, Mr. layman's statement* that 

 ionfiisa varies away f ror|i and not toward lecontei ; but desiring 

 to obtain more conclusive results, I visited the rocky pasture 

 again on Maj" 6, 1900, and secured another lot of hibernated 

 larvae. These, when obtained, varied a good deal in size, some 

 being apparently in the fourth and some in the fifth stage (the 

 normal number of stages is six), but were alike to all appear- 

 ances in other respects. 



Nearly everj^ Cynoglossiiin plant, out of more than a hundred 

 examined, showed the characteristic oval holes in the leaves, 

 and about one in four furnished a larva. Occasionally two 

 larvae were found on one plant. The plants were scattered 

 singly and in groups of two or three, rarely growing in a clump. 

 Pretty thorough exploration of the locality showed that the 

 plants were confined to an area of a few acres on the top of this 

 hill. Thirty-nine larvae were brought home and confined in 

 breeding cages. In the last stage three of these larvae had a 

 slightly different appearance from the rest and were placed in 

 a cage apart. The differences noted were a somewhat .stouter 

 body and a more hairy look, due not to a greater number or 

 length of hairs, but to their being lighter colored and thereby 

 more conspicuous. The .stouter look was, perhaps, due to 

 their being females, as all three produced fully marked clymene
