140 TWENTY-SIXTH REPORT ON THE STATE MUSEUM. 



Length of larva at maturity two inches ; diameter .22 of an inch. 

 Taken at Albany, September 1st, feeding on Solidago. 



Another larva, taken on the same food -plant, September 24th, was, 

 in all probability, the same species, although presenting a marked 

 difference in appearance from the one above described. The two 

 superior lateral stripes were in this nearly black, especially on the 

 abdominal segments, apparently resulting from the thickening of the 

 bordering lines and the extension of the interior ones over most of 

 the green ground. 



The larva, when captured, was found to have attached to its sur- 

 face a black oval parasitic egg-shell. It fed sparingly for several 

 days, when it died, and was transferred to alcohol and placed in the 

 State Museum collections. 



Catocala sp? 



Larva taken at Albany, N. Y., resting on the trunk of horse 

 chestnut, June 6th. Length 2.25 inches, diameter on eighth seg- 

 ment .35 in., elongated, attenuated at the extremities, quite flat 

 beneath when resting on a plane surface, bearing dorsally near the 

 posterior margin of the eighth segment a moderately elevated broad 

 wart directed backward, and having the posterior margin of the 

 eleventh segment slightly raised and projecting backward in a hood- 

 like form ; the following demi-segment has also its margin simi- 

 larly projecting, but in a less degree. Head .15 of an inch in 

 diameter, subquadrangular, flattened, slightly bilobed, gray with 

 lighter mottlings, surrounded laterally with a black band, which passes 

 over the vertex and anterior to the eyes ; the anterior portion of each 

 lobe paler, projecting, bearing each two black points giving out a 

 short black hair ; a similar point on the cheek behind the band, and 

 four microscopic ones on the paler bordering of the clypeus ; clypeus 

 depressed, nearly half the length of the head, slightly rounded at the 

 apex, with a brown medial line, and (under a magnifier) six papillae 

 bearing each a short white hair ; in front of the eyes two larger black 

 papillae with white hairs, and also some smaller ones behind the eyes ; 

 on each side of the apex of the clypeus is a conspicuous transversely 

 elongated black spot. The collar bears superiorly a double row of 

 four pale papillae with black hairs. 



Body with a few short white hairs laterally and a line of fleshy 

 filaments ranging with the legs. At rest, the second and third seg- 

 ments are closely wrinkled, while segments four to ten are wrinkled
