134 ENTOMOLOGICAL NEWS. [March, '09 



and a few days later (June 4th) I obtained 17 Catocala larvae 

 under the bark of one hickory tree, while Mr. E. A. Dodge and 

 son Ralph got nearly 30. This was a good haul for one tree. 



Again, on June 9th, I took 18 larvae on shag bark hickory 

 and on the I2th, 25. These various larvae gave us five species 

 of moths : obscnra, robinsoni, angusi, Judith and habilis. The 

 Judiths were among Mr. Dodge's find. A full-grown larva of 

 obscura is light gray, with somewhat lighter tubercles. The 

 longitudinal bands hardly distinguishable. No lateral setae. 

 On the top of the first and second abdominal segments is a 

 black cross line extending downward only over the dorsal and 

 sub-dorsal longitudinal bands. Head light gray, with a short 

 lateral (mouth) dash extending hardly to the middle of the side 

 of the head. Ventral side light gray and with the characteris- 

 tic round spots, not black as usual, but brown. A broken al- 

 most white band extends backward laterally from the first ab- 

 dominal segment. Feet and prolegs gray. The white lateral 

 band is narrow and just above the spiracles. Larva two and a 

 half inches long. A dark brown, more or less intermittent 

 wavy line separates the lateral band above the spiracles from 

 the broad illy-defined dorsal band. The latter includes the 

 dorso-central and the bounding lateral bands. There is a bristle 

 to each tubercle. No distinct hump. This larva, taken on June 

 9th, gave an imago of C. obscura on July 9th. 



A full grown larva of Catocala habilis is two and one-quarter 

 inches long, watery or smooth looking, gray, with a reddish 

 tint, more distinctly red along the spiracular band. The mid- 

 dorsal band narrow, lighter than the general color. A narrow 

 black band just above the flesh colored spiracular band. Head 

 grayish, with a red tint and with a broad, black lateral band. 

 A central black spot at the top or back of the head. True and 

 prolegs whitish, with a reddish tint. Ventral side greenish 

 white. The ventral spots smaller than usual in this genus, 

 pale brown. No dorsal hump and no lateral fringe or setae. 

 Sparse, short bristles on indistinct tubercles. This larva is 

 very active, jumping surprisingly. 



The last larvae we got on hickory were taken July 4th, 

 though caterpillars of both habilis and certainly robinsoni could 

 have been found much later.
