ASPIDIOTUS. 
The two following new species are both nearctic, not neotropical, types. 
Aspidiotus nigropunctatus n. sp. 
Female scale. — Subcircular to suboval, 3 mm. in diameter, only slightly 
convex, crowded together on bark. Color of scale dirty gray. Exuviae 
sublateral, pitch-black, with a narrow reddish margin. Exuviae cov- 
ered by an easily deciduous film of white secretion. Removed from the 
bark, the scales leave a conspicuous white mark. Immature scales are 
rather brownish. 
Adult female. — Orange brown, oval. Mouth-parts large. Five groups 
of ventral glands, cephalolaterals 16 (sometimes more), caudolaterals 10 
or 11 ; median group with 7 or 8 orifices. Anal orifice elongate in form, 
somewhat posterior to level of caudolateral groups of glands. Four 
pairs of lobes, these blunt and subtruncate, broad but not very broad, 
and flattened as in mimosce; median lobes close together but not touch- 
ing, their proximal sides parallel, their ends squared though rather 
irregular or subcrenate; second and third lobes distinctly notched; 
fourth rather low and rounded, with a smaller detached portion 
cephalad. Cephalad of this, the margin presents three small lob- 
ules. Plates not conspicuous, scale-like, short. Between the lobes 
are saccular incisions, such as are seen in mimosa^ etc. These are as 
follows: A short one at inner base of each median lobe; a large one, 
followed by a small one, between first and second lobes; a large one, 
with a small one on each side of it, between the second and third lobes; 
tliree rather small ones between the third and fourth lobes. The oval 
(dorsal) pores are as follows: One beneath each median lobe; four or 
live beneath (cephalad of) second lobe; a row of about nine beneath 
third lobe; a row of four or five beneath interval between third and 
fourth lobes. In a line with the last-mentioned row, but some distance 
cephalad, is an irregular series of twelve small round pores. 
Embryonic larva with conspicuous blue-black eyes. 
Habitat. — San Luis Potosi, Mexico, on shrub called " trueno," October 
12 ; 1894. (Townsend No. 13; Div. Ent. Dept. Agr. No. 0112.)
