Pseudococcus filamentosus Cockerell. 
Tanghulan, Mindanao, on Coffea, very destructive (Baker). 
Gossyparia spuria (Modeer). 
Denver, Colorado, immature, wintering on bark of elm (E. Bethel). 
Fonscolombia braggin. sp. (Figs. 11-15.) 
@. Elongate (when mounted on slide), 165 microns long and 75 broad, the sides 
nearly parallel. Bright raspberry red in life; colorless after boiling. In the following 
account the measurements are all in microns: 
Antenne 7-jointed, joints 3 to 6 broader apically than basally, so that the lateral 
profile is stair-like; joints 5 and 6 each with a curved spine at side, 7 with a spine 
and many bristles; length of joints, (1.) 25, (2.) 18, (8.) 32, (4.) 20, (5.) 16, (6.) 16, 
(7.) 26. Distance between antennz 70, width of base of antenna 45. Derm with 
scattered round glands, and very minute bristles. Mouth parts large, about 125 
across; labium short, about 63 long and broad at base, not distinctly jointed. Anal 
ring with six short spines. Caudal bristles about 140 long. Anterior femur with 
trochanter 112, middle ditto 120, hind ditto 125; middle tibia 55, hind tibia yes 
hind tarsus (excluding claw) 87; tarsi curved. The claw has a very minute denticle 
on inner side near end. 
Second stage.— Antenne 6-jointed, 52 apart; joints measuring (1.) 20, (2.) 18, 
(3.) 20, (4.) 18, (5.) 14, (6.) 25. Legs stout; middle leg measuring, femur with 
trochanter, 88; tibia, 45; tarsus (without claw) 50. Tarsus with two stout bristles 
on inner side. Derm with regularly placed (in longitudinal and transverse rows) 
small nipple-like narrowly truncate glands. 
Hab.— On roots of Berberis repens, Boulder, Colorado, May 31, 1911 (Bragg) 
The genus was described from Europe, and is new to America. The 
species is aberrant by the seven-jointed antenne and the character of the 
dermal glands, but it does not seem necessary to propose a new generic name 
for it. The females produce a quantity of loose white cotton-like secretion, 
but are not hidden by it. Our examples, though adult, had not begun to 
produce eggs. 
Ripersia trichura Cockerell. 
On April 4, 1914, we found several specimens of this elongate species 
under rocks, in nests of Lasius americanus and Formica sp. at Boulder, 
Colorado. It is new to Colorado. 
Aspidiotus translucens (Cockerell). 
This is bodily called A. transparens Green, but that name was originally 
applied to A. destructor Signoret.
