356 Notes on Lepidopterous Larve, [ZOE 
of prothorax, which instead is longer hairy especially on borders;. 
moreover all the segments (except head) present a pubescent 
appearance, being covered with the short hairs arising from the 
spinous tubercles, these hairs usually (in three specimens—not 
in the faintly humped one) becoming longer on the dorsum along 
the median row of hump-like transverse ridges. The pubescence 
in these three specimens (above mentioned) also becomes some- 
what longer along the sides of the larva. Head not so glabrous, 
black, but not so polished. Eyes apparently nearly the same. 
Mandibles apparently nearly the same. Legs and prolegs same; 
spiracles same, consisting of g pairs, on sides of segments 2, and 
5 to 12, those on 11 and 12 situated more on dorsum of seg- 
ments. . 
Described from four specimens. Southern N. Mex. General 
colors noted in life. It had occurred to me that possibly there 
were two species represented in the above larve, but their 
uniform pubescence and the connecting variations between them 
_ lead one to consider them as belonging to the same species. 
Their pubescence seems to point them out at once as distinct 
from the species on AZriplex. 
Mr. W. H. Edwards has treated in a most interesting manuer 
of the special organs of segments 11 and 12 in the larva of 
Lycaena pseudargiolus (Butt. N. Am. vol. ii. Lycaena ii, iii, 
pp. 10-16). A figure is; given of the last segments (p. 14), 
showing these organs. All of the four larve above described from 
mesquit show the organs very;plainly ; the median transverse open- 
ing on 11, and the two tubes on 12 wholly withdrawn inside and 
showing as a rounded stigma-like organ with many wrinkles. 
radiating from the centre. 
UI. LARVA OF OIKETICUS TOWNSENDI (RILEY MSS). 
This species is our common bag-worm in Southern New Mex- 
Some detailed notes have been published on this species in 
the Caz, Ent., 1892, p. 199, under the name‘ 7. hyridopteryx sp.”’ 
Specimens hadgbeen sent to Dr. Riley, who wrote me too late for 
insertion in the above-mentioned notes that the insect proved to 
be a new species of Oiketicus, which he would describe at some 
future time under the above name. ‘The present seems an ap- 
ico.
