60 Mr. T. D. A. Cockerell on some 
the whole of the digits white ; hind feet very short in propor- 
tion to the general size; fifth hind toe very long, reaching, 
without claw, nearly to the end of the second phalanx of the 
fourth. ‘Tail slender, finely haired, uniformly dark brown 
throughout. 
Skull rather thin and papery for its size, with a large 
rounded brain-case,and broad rounded interorbital space, whose 
edges are quite unbeaded, scarcely even angular. Zygomatic 
plate narrow, slanting backwards in front. Palatal foramina® 
large and open, not quite reaching backwards to the level of 
the front of ™1. Posterior edge of palate level with the 
middle of ™3, Bulle small. 
Molars large and oblong, as in Oryzomys and Rhipidomys. 
Dimensions of the type (an adult female skin) :— 
Head and body 117 millim.; tail 123; hind foot (moist- 
ened) 21°8; ear (c.) 17. 
Skull: basal length 24, basilar length 21:7, greatest 
breadth 15:4; nasals 10°3x3°6; interorbital breadth 5; 
interparietal 3°2x 10:2; length of zygomatic plate 2:2; 
palate length from henselion 12; diastema 7'8; palatal fora- 
mina 5°5 x 2°43; length of upper molar series 4°7. 
This fluffy-haired Vesper Mouse has very much the appear- 
ance of an Acodon, say of A. olivaceus, but its short feet and 
broad heavy molars show that it is essentially different from 
any member of that group. 
X.—On some Coccide obtained by Mr. C. A. Barber in 
the Island of Antigua, WI. By T. D. A. CockEreELn, 
Entomologist of the New Mexico (U.8.A.) Agricultural 
Experiment Station. 
WHEN leaving Antigua Mr. Barber was so kind as to send 
me a parcel of scale-insects which he had collected there ; 
and as the specimens prove to be of considerable interest, the 
following notes are offered. 
(1) Orthezia insignis, Douglas. 
On roots and stems of Clitorea ternatea and stems of 
Coleus; very destructive to the latter. This extremely 
troublesome species is getting very widespread ; out of doors 
in the tropics and in temperate regions in hothouses.
