Sept., 1906.1 Kunze : Description of Lepidopterous Lary.e. 133 



A spinose tubercle on penultimate joint pink, tipped white, at base green. Spiracu- 

 lar line violet-lavender. Spiracles black, edged white. Thoracic feet green, toes 

 brownish. Abdominal feet and toes brownish, at base green. 



Length at rest, 45 mm.; in motion, 54 mm. ; diameter 8 mm. 



Larvae pupated in stone jar, partly filled with a sandy loam, and a 

 few weeks later removed three pupse, of the usual shape of a Sphin- 

 gicampa. May 10, 1905, a fine ? emerged, which during the 

 night oviposited a few ova of a transparent, pea-green tint. August 

 8th another 9 emerged which not being looked for, had become a 

 total wreck. Of all the larvae I ever have seen or bred East or West, 

 this Sphingicampid is the most beautifully marked and ornamented. 

 Its proper habitat is southeastern Texas and Mexico. I have received 

 the imago from Comal County, Texas. 



Larva of Copidryas cosyra Druce. 

 During August, 1904, I discovered some larvae feeding on the 

 tender young joints of a cactus — Opuntia arbuscula, a prickly-pear — 

 having cylindric branches or segments, of which I cultivated a bed on 

 my cactus ranch. The plants I had collected fifteen miles north of 

 town in February of the same year. The larva was of cylindric 

 shape, olivaceous in color, and more or less covered with fine hairs. 

 I sent two to Dr. Harrison G. Dyar, with some of the foodplant. The 

 larvae were inflated for the U. S. Nat. Museum, but he was unable to 

 recognize the insect. In the meantime I caged a number of good-sized 

 larvae in a stone jar containing loam, and obtained six or eight pupae, 

 which transformed a few inches below the surface. Early in the spring 

 of 1905, I sent all these pupae to Dr. Dyar, inasmuch as I had often to 

 absent myself, collecting cacti all over this territory for export, and 

 could not watch the pupae. In due course of time Dr. Dyar informed 

 me that he had obtained imagines of Copidryas cosyra, from the pupae 

 I sent him, and requested I should watch for more of these larvae and 

 take notes during breeding of the same. 



Early in August I found this larva again on the prickly pear, from 

 one half up to three fourths inch in length, and in a few days collected 

 eleven or twelve larvae. Not having an empty stone jar convenient, 

 I had to place the young larvae in a tin canister, which was kept inside 

 of ray tent-house. We had the hottest summer for a decade, with a 

 temperature of 115 degrees in the shade and the larvae were killed. 



The first larvae I found August 9, 1905, and the smallest measured 

 12 mm. in motion, and 2 mm. in width.
