ently without this posterior row, but has instead a terminal 
circlet of spines of different sizes, a lateral one on each side much 
the largest and rather claw-shaped, with the point directed 
inferiorly. The other spines are much smaller. 
Described from one specimen. 
II, LYCAINID ON. MESQUIT. 
Four specimens of a beautiful light green lycaenid larva were 
beaten, May 16, 1891, from Prosopis juliflora south of Mesilla, 
New Mexico. At the time of capture, they measured from 5 to 7 
mm. long, and were of the exact shade of green of the mesquit 
leaves. They feed on the underside, thus escaping observation- 
The head, in these and other lyczenid larve, appears to the 
aked eye as a small black tubercle on the ventral aspect of 
the cephalic end of the body, which with their other characters 
gives them much the appearance of certain dipterous larve. 
Description of Larva.—Length (strongly curved), 4 to 7 mm.; 
greatest width, 2 to 3 mm.; greatest thickness, 2 mm. Quite 
similar in general outline and appearance to the lyceenid on 
Atriplex described by the writer, from Arizona (Am. Nat. 1893). 
Differs only as follows: Light green in color, with a thick 
clothing of minute and more spinous tubercles, from each one 
of which springs a minute hair. With or without the median 
and lateral rows of reddish spots on segments 3 to 10 (two with 
and two without). One of the specimens, with the red 
the median row of spots. The dorsa of segments strongly or 
hardly at all produced into the raised transverse ridges (one 
strongly, two moderately, and one very faintly). Anterior 
segments gradually increasing in width, to segment 6, seg- 
ments 6 to 10 about equal in width, posterior ones narrow- 
ing to anus. Some or none of the-minute black spinous 
tubercles interspersed among the whitish ones (more in two 
cases—same two specimens referred to above as having the 
rows of red spots; and a considerable number along dorsal 
region in the other two). All four differ in having none 
of the short and stout black spines on anterior portion of dorsum
