considerably; according to the condition of the weather. Our records show 

 from four to eight days. 



Second Instar. — Much as in preceding; a little over 3 mm. in length; 

 colour generally lighter. 



Third Instar. — Length about 6 mm. Colour greenish, with a yellow 

 lateral stripe and a light dorsal line, sparsely hirsute ; head black or dark 

 green. 



Fourth Instar. — Length about 15 mm.; uniformly dull grassy green ; 

 head rather darker, large, bilobed, with many ferruginous coloured short 

 hairs ; body also covered with same clothing, and also more scattered 

 long black bristles. A whitish lateral stripe edged below with darker ; 

 ventral stripe very faint. 



Fifth Instar. — Average length about 27 mm.; colour slightly darker 

 than in preceding stage, head concolorous. A rather wide lateral band on 

 the line of the spiracles, and continuing on the side of the head; dorsal 

 line obscure. Head small, more so than the body, distinctly bilobed ; 

 head and body covered with many short black tubercles or hairs. 



Pupation. — The method of pupation and spinning the girdle is so 

 similar to various well-known species of Fontia, that we do not repeat it 

 here. We have never been able to find the pupa in nature, but Mr. F. 

 X. Williams tells us he has found several pupae of both sara and atisonides 

 suspended at the base of the food-plant. 



Pupa. — Colour very light silvery-gray, the ventral area lighter ; pro- 

 notum bluntly produced, the wing-cases thereon marked in white ; ventral 

 line and ridges dark ; outline curved, more so than ausonides, but not so 

 much as in lanceolata or pima ; spiracles indicated by blackish points. 

 Considerable variation occurs in the curvature of the profile; one pupa we 

 had was very straight, more so than in any of the other species ; palpi 

 case more or less recurved, sometimes quite noticeably so. Normal 

 length 22 mm. 



We are much indebted to Prof. Chas. A. Shull for copying for us the 

 text in this genus from Edwards's Butterflies of North America. 



ENTOMOLOGICAL SOCIETY OF AMERICA. 



The fourth meeting of the Entomological Society of America was held 

 in Baltimore, Dec. 30 and 31, in affiliation with the American Association 

 for the Advancement of Science and other Societies. The number in 

 attendance was exceptionally large. 



The sessions were called to order on Wednesday morning by the
