Sétif, about half-an-hour’s walk from the town.’’? The 
scales were unusually grey, and larger than typical 
examples. 
Mytilaspis minima, sp.n. (Plate IV., figs. 1-5.) 
? Scalevery convex, filiform, straight or curved, margins irregular, 
owing to the numerous hairs on the leaf of the food-plant ; colour 
pale yellow- brownor red-brown, anal extremity usually paler. Larval 
pellicle terminal of the same colour as the scale. Long. *50—1°50mm. 
? Adult elongate, attenuated in front ; antennz rudimentary. 
Pygidium (figs. 1, 2, 3) rounded, lobes short, median pair large 
and widely separated, with the lateral margins usually emar- 
ginate ; second and third pairs rudimentary. There are generally 
three pairs of plates on each side beyond the median lobes, which 
are very long and broad ; and between the median lobes a much 
shorter pair, widely separated. When present thereisa rather long 
spine near the second, third, and fourth pairs of lobes, but they are 
often wanting. Five groups of compound spinnerets are present ; 
anterior group with 2-5, anterior laterals 3-6, posterior laterals 3-6. 
gd Scale convex, a little wider than the larval pellicle ; white, 
with the larval pellicles darker. 
¢ Second stage elongate-ovate, closely resembling the ¢ in cha- 
racter. Pygidium (fig. 4) with 5 almost continuous groups of com- 
pound spinnerets; the anterior with 3, anterior laterals 7-8. posterior 
laterals 4—6 ; the median lobes are very broad and deeply emargi- 
nate ; the second and third pairs are scarcely visible. The plates 
are somewhat larger and more numerous than in the 9. 
Larva. Antenne (fig. 5) of 6 joints, of which the third is nearly 
as long as the rest together ; fifth shortest, first much the widest. 
Hab. “ Among the rocks at the brow of the wooded 
slopes of the Mansourah; on Ficus carica, L., 24, x., 95.” 
‘he 2 were scattered over both surfaces of the leaves ; 
but the ¢ were on the upper side along the ribs. This is 
the smallest species I have yet studied; and in other 
respects it seems quite distinct. It belongs to that section 
of which M. cordylinidis, Mask., is the type. 
Mytilaspis ampelodesmx, sp.n. (PI. 1V., figs. 6, 7.) 
Scale of the ? long and narrow, sides parallel, white ; larval 
pellicle white or pale yellow, transparent; second pellicle red- 
brown inclining to piceous in the centre, usually covered with 
white secretion ; ventral scale white or yellowish white, and appa- 
rently incomplete. Long. 1-2°25 mm., lat, 50 mm.
