THE CANADIAN ENTOMOLOGIST. 



LARVA OF DATANA, UNKNOWN SPECIES. 



During my last week of collecting in the Huachuca Mts., Cochise 

 Co., Arizona, I found, Aug. iith, 1899, eighteen D at ana larvae on a 

 Manzanita bush ( Arctostap/iy/os glauca) or Western bearleaf. This 

 larva was not known to me. and therefore I was anxious to send it to the 

 artist who made the figures for Prof. A. T. Packard's " Bombycine 

 Moths." To all appearance the larvae were nearly full-grown, and I had a 

 negative taken of them by an ornithologist camping near by, so as to have 

 a memento left in case they should transform before reaching their 

 destination. Cloudy weather and drizzling rain late in the day made 

 it difficult to obtain a good picture. I had to mail the insects early 

 the next morning from Fort Huachuca, which is 12 miles from Ramsey 

 Canyon, and further delay was hazardous. I took a hasty description of 

 the larva, then boxed two of them in a tin canister for Mr. L. H. Joutel, 

 the artist, care of American Museum of Natural History of New York 

 City. But, unfortunately, these larvae, although received, were never 

 turned over to the artist, whose address I could not find in my notebook. 

 The other sixteen larvae I sent to Mr. Chas. Palm, then rusticating in 

 Sullivan Co., N. Y., with a view to having these raised on some eastern 

 food-plant. The larvae refused everything offered, and finally Mr- Palm 

 set them at liberty in the bush, trusting that some might transform there. 



Description of larva : Body black, with longitudinal yellow lines, of 

 which three are subdorsal on each side of a broad, black dorsal band, and 

 one sub-spiracular yellow line ; another broad, black band between the 

 last subdorsal and spiracular line, of nearly the same width as that 

 on the dorsum. A yellow, central abdominal line from the first to twelfth 

 segment. Head and anal plate pitchy black and smooth. Abdominal 

 protuberance at the base of black legs of a purplish-pink colour. 

 Spiracles black, enclosed by a circular silvery line. All true and 

 abdominal legs pitchy black. Mouth-parts purplish-pink. Long white 

 hairs from 5 to 8 mm. long all over the body, except dorsal black band, 

 on which the hairs were shorter and more scattered. 



Length of larva, 35 mm., and width, 5 mm. When at rest the larvae 

 assumed the usual curved posture, the anterior and posterior three 

 segments well thrown up. R. E. Kunze, Phoenix, Arizona.
