104 FIFTH REPORT OP THE ENTOMOLOGICAL COMMISSION. 
The females occur on the bark of the small limbs; the males upon the 
leaven, 
8oale of female.— The scale of the female is long, narrow at the anterior end, much 
widened posteriorly, and <juite convex. The exnriae are brownish yellow ; the secre- 
tion, of which the remainder of the scale is composed, is white; but all of my speci- 
mens appear dark gray, being more orless covered with the hairs of the stem to which 
the stale was attached, and with dust. Length of scale 2""" (.08 inch). 
i\ inalt. — The last .segment of the female presents the following characters: 
The anterior groupof tpinntrttx consists of about ten ; the anterior laterals of sev- 
enteen to twenty, and the posterior laterals of ten to eighteen. 
This species differs from all Diaspime known to me in having a single undivided 
lobe on the meson ; this lobe is large and rounded distally. The second and third 
lobes of each side are very small and are laterad of small incisions in the margin of 
the segment. In each case there is a reniform thickening of the body wall bound- 
ing each incision anteriorly. There is also asimilar incision with a rudimentary lobe 
and reniform thickening of the body wall about midway between third lobe and 
penultimate segment. 
The plates are inconspicuous and spine-like; there are usually one or two laterad 
of second ventral spine, two or three between third and fourth lobe, and usually five 
between fourth lobe and penultimate segment. The penultimate and antepenultimate 
segments bear six each; those on the latter are much expanded at the base. 
The spines are long and conspicuous; those on the dorsal surface are situated as 
follows: One on each side at the base of the lateral margin of median lobe, one 
laterad of each of the second and third lobes, and a fourth one near the center of the 
anterior group of plates. Those on the ventral surface are as follows : A short one 
nearly ventrad of the first dorsal spine, a large one laterad of each of the second and 
third dorsal spines, and a fourth one a little cephalad of the fourth dorsal spine. 
Scale of the mole.— The scale of the male is snowy white, with the larval skin very 
light yellow. The texture of the scale is quite loose and the carinas prominent; 
length, 1.25 mm (.05 inch). 
Male. — The adult male is as yet unknown; many pupae were collected August 17, 
1860. Specimens of these mounted in basaku are bright yellow in color, with eyes 
purplish black. Fully grown male larvae in basalm are yellowish brown. 
Described from four scales of the female, four females, hundreds of scales of the 
male, and many male pupae and larvae.
