2 98 PSYCHE. [December 1898.
ally 180-22.5 p and being of about the same width 165 p the femur appears more slen- der. The ovisac of lekgii is also not so compact as in this species. The drawings are by Prof. Tinsley who is also respon- sible for the comparison with allied species. SECOND NOTE ON A NEW HEMI-
LEUCA.
HemHenca sororia race olivine, Ckll.,
Psyche, 1898, p. 252. ;?. (Sta. Fi, N. M.) On Aug. 20, 1898, Mr. John Davis sent me some larvae collected at Maxwell City, N. M., stating that they were then extremely numer- ous, and were devouring the pastures. With the larvae were sent pieces of grass, which Prof. E. 0. Wooton identifies as a Muhlen- bergia probably M. iexaua Thurh. (^orfed Scrib.). From these larvae I bred four moths of olivwe, which was only known heretofore bya single;? ! A male emerged Sept. 13, two males Sept. 14 and a female Sept. if.
Larva. Of the living larva, I noted as fol- lows:- Ochreous with a very dark brown
head ; body irregularly marbled with very dark brown, especially about the sutures; tufts of spines as usual in the genus, the central ones black, the lateral ones (sjinnles) ochreous with black tips; thoracic legs black.
The skin if; sparsely beset with colorless hairs. Spiracles narrowly edged with black. Cocoon. The cocoon is composed mainly
of fragments of the Muhlsnhergia. loosely woven, with many open spaces.
Imago.
The males agree in the main with
the Santa F&. type, but are perhaps, a little grayer. The female expands 65
rnm., and
has a warmer, more rosy color than the males. The general color of the anterior wings is nearly uniform, with the two pale bands dis- tinct.
Compared with the description of H. sor- oriel Hy. Edw., the 2 oliviae differs thus:- Costa of primaries orange-ferruginous
throughout ; secondaries above with the nerv- ures pale ferruginous ; on the under side the nervures are pale ferruginous on all the wings, and the costa of the primaries
is broadly orange ferruginous, subf uscons at base, that of the secondaries washed with blackish ; head clothed with dark fuscous hair, gray on vertex and occiput ; thorax with dense long gray hairs ; antennae entirely bright orange; abdomen above with fuscous hair, chestnut on the first two segments; hind margins of third to fifth segments with red hair, which is replaced by white on the ex- treme sides, and beneath except in the mid- dle; apex with mixed fuscous, white and red hair. The expanse is 11 rnm. less then that of sororta.
H. oliviae is of about the same size as
Ti.
sorork hualafai (Neumoegen), from S. W.
Arizona, but differs in the marking~i. The three forms, sorori~t, hualapai and oliviae ore clearly geographical races of a single well marked species.
In the Mesilla Valley, N. M., I have never taken H. oliviitr,, but only II. main race ar- temis (Pack) and H. jwto Pack., the former being much the most frequent.

A CURIOUS COCOON UF ATTACUS CECRO-
PIA. -In September last I found a very large larva of Cec~o~Ga feeding on willow in a swampy place. I took it home and it began its cocoon the next day, in a white paper box, from which I removed allleavcsi.
The cocoon
was glistening white at first, and in this StRte was packed with white cotton for transporta- tion from Vermont to Brookline. The box
was unopened for a month, and when the
cocoon was taken out it was nearly a11 green, the small spaces not green being just off white. The pupa seems to be in good condi- tion and is evidently alive.
