dorsal line or stripe, but on the anterior 
edges of segments 6 to 11 is a little narrow 
yellow spot on each. 
A. celtis is yellow green over dorsal area, 
blue-green on the sides ; in middle of dor- 
sum is a pale yellow stripe, and on this a 
deep yellow oval spot is set on the anterior 
end of each segment from 3 to 12 or 13; 
sometimes the stripe is wanting, but the 
spots are always present ; these are larger 
than any on alicia, each occupying more 
than half the breadth of the segment. 
These differences in the larvae are de- 
cisive of the distinctness of the butterflies. 
The eggs are alike; the chrysalids are 
closely alike. Mrs. Peart, who has made 
drawings of both chrysalids, has called my 
attention to the serrated edge of the carina 
on abdomen of alicia, as being different 
from that of celtis, which the drawings 
represent as evenly edged, but I do not hap- 
pen at present to have a chrysalis of celts 
at hand for more exact comparison. 
LARVA OF EURYCREON RANTALIS GUEN. 
BY FRANCIS HUNTINGTON SNOW, LAWRENCE, KANS. 
THE LARVA of Lurycreon rantalis is re- 
ported by Prof. F. H. Snow to have caused 
serious injury to various garden vegetables, 
weeds and other low and tender plants (a 
list of which is given below), in Kansas, 
in June and July, and a description of the 
larva is given by him in the Lawrence 
(Kans.) daily journal, 28 July 1880. 
To preserve this description from loss or 
render it more accessible to entomologists 
generally, it is here reproduced, with Prof. 
Snow’s permission :— 
Head pale yellowish red without spots. 
Body nearly cylindrical, about 25 mm. 
long. Color, light green with a narrow 
yellowish white band on each side of dor- 
sal surface except on second segment. Seg- 
ment 2 (the head is segment 1) has a sin- 
gle short longitudinal jet black dash be- 
_ tween dorsal and stigmatic surfaces on each 
side, with traces of a second and third spot 
in some individuals. Segments 3 and 4 
have each two such spots on each side. 
Segments 5 to 12 inclusive have each three 
circular jet black spots on each side at the 
vertices of the angles of an imaginary 
equilateral triangle having two angles on 
the anterior half of the segment and one 
on the posterior half. In some individuals 
these black spots are minutely pupiled with 
light green. From the lower of the three 
spots proceeds a single central yellowish 
hair. Below this lower spot upon each 
side of each segment may be detected an 
exceedingly minute black dot, which would 
easily escape the ordinary observer. The 
thirteenth or anal segment has two large 
black spots on dorsal line and one small 
black spot on each side. The lower sur- 
face of each segment has a transverse se- 
ries of eight annular black spots. The 
second, third, and fourth segments have 
each a pair of true legs, and segments 7, 
8, 9, 10 and 13 a pair of prop legs. 
The plants upon which this larva was 
found are : Sweet potato (Ipomoea batatas) , 
alfalfa (Medicago sativa), beets (Beta 
vulgaris), peas (Pisum sativum), pig- 
weed (Amarantus), purslane (Portulaca 
oleracea).
