though it la made out with difficulty. On ventral surface, rudimentary i 
feet quite distinct. 
Adults unknown. 
Received bv the Division of Entomology at Washington from Dr. 1 
Vasey. of the Department of Agriculture, specimens on leaves of 
Acarhi (mes(mite) from Chilhua, Mexico, January 27, 1886; from! I 
\Y. E. Collins. Ontario. Oil., on Acacia, October 6, 1889; again on 
Acacia from Los Angeles, Cal., and on Bemera microphylla, Carmen j 
Isle, off Lower California. This same species, it is stated in Mr. 
Pergande's notes, was found on leaves of mesquite from Bastophilus, I 
Mexico: Div. Bnt. No. 3863. No. 587b is doubtless this same species, 
from Fullerton, Oil., July 30, 1893, on an undetermined plant. Type 
3863, from Chilhua, Mexico. Described from numerous pupa-cases.

La/rva. -Size about <>.S9 by 0.52 mm.; yellowish white. A series 
all around of about 30 setae. On dorsum are 5 pairs of moderately 
developed setae, a pair on cephalic segment, a pair on each of the 
thoracic segments, and a pair at vasiform orifice. Margin of ease 
slightly crenulated. On the dorsum a few pores may occur somewhat 
promiscuously, and there are a few groups of pores around the mar- 
gin. This stage in many respects approaches quite close in structure 
to the pupa-case. 
Pujxt-case. — Size about 1.79 by 1.26 mm. ; subovate, narrowed ceph- 
alad Color of younger pupae, yellowish to white, and usually with- 
out other coloration. In more mature examples the color may vary 
from whitish to those more or less mottled with brownish, with 
extreme cases almost uniform brownish black, though in these latter 
08868 such examples have plainly been parasitized, and this color may 
have resulted from this fact. Typically, this brownish coloration 
occurs in dashes, from the outer margin inward, varying distances, 
and more or Less radially. Along the dorsi-meson there is a more or 
less <'M'ar Longitudinal central stripe, with an interrupted stripe ol 
dark brown on each side, these latter varying considerably in extent 
and distinctness In well-marked specimens the radial wedge-shaped 
dashes ma\ extend quite into these subdorsal bands of dark brown. 
Pupa case, when young, with moderately rounded keel, otherwise 
flat; at Length becoming somewhat convex, and raised on an unusually 
high yertical fringe of white wax. There is no lateral fringe, but 
just w ithin the margin all around there is a series of groups of waxen 
rods. These rods arise from groups of from usually 22 to 26 circular 
pores, Bach bundle of rods Ls surrounded with a rather short cylin-
