Hemileuca maia Drury. As will be seen from the above notes, it seems that the female of this species oviposits 

 here on Salix, or other food plants, in November; the eggs hatch the following spring. Below are notes on the darker 

 larvae, supposed to be maia. 



April 22, 1891: A twig of Populus fremontii was found on college farm, bearing eggshells of Hemileuca from which 

 the young caterpillars, 2J to 3 mm. long, had just hatched and begun eating the green leaves. As these were so young, 

 the color could hardly be depended upon. Mr. H. G. Dyar identified them as Hemileuca or an allied form. 



May 16, 1891 : Three miles south of Mesilla, near the Rio Grande River, a mass of dark Hemileuca larvae was noticed 

 on a twig of Populus fremontii, and another similar mass on a twig of Salix sp. near by. The larvae held on to the 

 twigs by means of slight but quite strong silken webs, and measured 17 to 20 mm. in length. 



May 13, 1892: Some larvae, which agree well in general color and appearance with the above, were found on mee- 

 quite (P. juliflora) near the college. They were 1$ to 2 inches long. One larva pupated on top of the earth in a breed- 

 ing cage, May 27. This, with an alcoholic larva, was sent to Dr. Packard, who wrote that they were H. maia. 



July 25, 1892: East of Navajo Springs, Ariz., I found a number of specimens of a large brownish and blackish 

 larva, which may be H. maia, feeding on Artemisia fdifolia, a greenish-gray sage. They could not be found on the 

 sage after passing a certain very restricted area, though they were numerous where they did occur. It may have 

 been another species. 



Note. — I have repeatedly handled the maia and artemis larvae in all stages without being stung in the least by 



HEMILEUCA GROTEI Grote and Robinson.

[Antennae black; palpi and front black; behind the antennae a broad band of white hairs, 

 extending vertically along sides of pectus for a short distance; thorax black, intermingled 

 with sparse white hairs and with a lateral tuft of deep carmine hairs on metathorax; abdomen 

 black with a few white hairs dorsally, and the segmental divisions marked by white hairs ven- 

 trally, anal tuft consisting of orange-red hairs ; pectus and legs black ; base of legs fringed with 

 deep carmine hair. 'Primaries deep brown-black crossed beyond the cell by a broad irregular 

 band of white, very variable in width and outline; broad at the costa, it is much contracted 

 opposite the cell and is even at times entirely divided into an upper and lower portion; the 

 lower portion may be of even width throughout, or may gradually taper toward the inner 

 margin; the outer margin of the band may be almost straight, but is usually sinuate, curving 

 gently inward below the cell; it is often distinctly crenulate; at the end of the cell is a whitish 

 lunate mark, broadly surrounded by deep black scaling which encroaches more or less into 

 the white band, as mentioned above. Secondaries slightly deeper in color than the primaries, 

 similar in maculation, discocellular lunule smaller and less distinct, white band angled oppo- 

 site cell, as variable as on primaries. Beneath as above, white postmedian band rather broader 

 as a rule but very variable. Expanse, S 38-48 mm.; 9 45 to 54 mm. Described from 4 

 o* S and 10 ? 9 in collection Barnes, from Kerrville, Tex., (4 ? ? ) and Chiricahua Mountains, 

 Ariz. All very constant. — J. McDtjnnough.]

[ <? . Antennas orange; palpi and front deep purplish red ; thorax white, mixed with purplish 

 hairs posteriorly; abdomen dorsally with long red hairs, ventrally yellowish white; pectus 

 and base of legs purple-red; tarsi black; tibiae fringed with whitish hairs; primaries silvery 

 white crossed by two black bands; of these the antemedian is bent outward below costa, thence 



i [A female from Los Angeles County, Cal. (Coquillett), in the U. S. National Museum, shows an apparently good subgeneric character not 

 mentioned by Grote; the antenna are long pectinate on both sides. In H. tricolor they are only serrate on one side on basal half or more.]
