366 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
chrysalids either amoog the leaves or desert the tree and seek some 
retired place, where they spin a slight loose cocoon, within which they 
remain through the winter, appearing in the imago state by the mid- 
dle of the following June. 
Tke hutterthj is brown, the fore-wings are browii with a transverse semi-transparent 
band across the middle, ami a lew spots towards the tip of a honey-yellow color; 
hind wings with a short rounded tail on the bind angles, and a hroad silvery 
baud across the middle of the underside. The wings expand from 2 to 2J inches.

Remedies. — Nearly all the insects which prey upon the foliage of the 
locust can be gotten rid of by hand-picking and by collecting the leaves 
in autumn and burning them ; in this way cherished shade trees can be 
protected. 
12. Dasylophia anguina Abbot and Smith. 
The eggs of this moth were sent me by Miss Emily L. Morton, of 
Newbilrgh, ]S. Y., having been laid about the 20th of July. She has 
never found the larvae on any other tree than the locust, and then only 
rarely. The larvae hatched July 25, at Brunswick, Me.; the first molt 
occurred July 28, the second August 6, and the third August 10 to 11 , 
the fourth August 20 to 22. 
Egg. — Spherical, whitish, surface seen under a good lens to be very finely granu- 
lated. Diameter, .8 mm . 
Larva directly after hatching. — Head very large, nearly twice as wide as the body is 
behind the middle, rounded, yellowish amber with a lateral black stripe. First ab- 
dominal segment shining red, with two high slender subdorsal tubercles ; two similar 
but much smaller tubercles on the eighth segment, which is also reddish. Body deep 
pea-green, shining, with six very narrow dorsal, subdorsal, and lateral black lines. 
Anal legs long and slender, dark red, and with the two last abdominal segments (9 
a,nd 10) uplifted much as in the full-fed larva, at an angle often of 45 degrees. All 
the legs, both thoracic and abdominal, dull greenish. Hairs stiff and black, mostly 
thickened at the end ; about as long as the body is thick. Length, 3 to 4 mm . 
Larva after first molt, July 23. — Head amber-colored, no wider than the body. 
Body pale green, the dark brown stripes, especially the dorsal one, more distiuct ; 
the dorsal line is continuous; the two lateral ones somewhat broken ; the hairs are 
still black, but not so much thickened as before. Markings nearly as before, but the 
first and eighth abdominal segments not so deep red as in stage I. Length, 6 to 7 mm . 
Lamm aftei second molt, August 6. — More like the mature larva?. Head of moderate 
size, but little wider than the body, rounded, dull pale reddish orange. Body smooth 
and shining, straw-yellow ; a dorsal black line ending on the polished black knob 
on the eighth abdominal segment. Three lateral, more or less interrupted black 
lines in a whitish band, the middle of the three the faintest. This band incloses on 
the first abdominal segment a polished jet-black tubercle. Low down on the sides 
of the body are twelve black spots, one at the base of each foot, when they are pres- 
ent; four black spots on the front part of the supra-aual plate. Anal legs uplifted, 
exteusile, black on the tips. Length, 15 mm . 
Larva after third molt, August 10 to 11. — Only differs from the preceding stage in its 
more distinct, deeper hues, especially the pale lilac tint on ninth and adjoining seg- 
ments, and the larger, thicker body. The four black spots on the base of the short 
enpra-aual plate are united to form a continuous baud. Length, 22 mm . 
Full-fed larva.— Head rounded, greenish amber; body smooth, of nearly uniform 
thickness, with a low rounded jet-black kuob ou tip of the eighth abdominal seg-
