160 Mr. T. D. A. Cockerell on two new 
sides of the leaves, not clustered together. The green walking 
females without sacs are extremely abundant on the midrib. 
Length of 2 with sac about 5 mm.; without sac, about 3 mm. 
long, and 23 or less broad. Although the scales are green, they 
turn red-brown on being boiled in caustic soda. 
The antenne are of eight joints. The 3rd joint is distinctly the 
longest ; the 4th next longest; the 5th and 2nd, about equal, next ; 
the 6th, Ist, and 8th subequal, next longest; and the 7th shortest 
of all, The Ist joint is about as broad as long; the 2nd joint has 
one long and one very short hair; the 3rd has two very short ones; 
the 5th and 6th have each a long hair; the 7th has one or more; 
and the 8th five or six hairs, none apparently longer than itself. 
Femur rather longer than tibia; tibia about twice as long as tarsus. 
Tarsal knobbed digitules about as long as breadth of tarsus; the 
knobbed hairs are longer, but not mwch longer, and very slender. 
The tibia has a few shorter bristles. A long hair springs from the 
trochanter, and a shorter one from the distal end of the coxa. 
The scale, seen by transmitted light after boiling in dilute soda 
solution, shows, at least in places, very many round gland-spots, 
asin Lecanium loxgulum. The margins of the scale exhibit short 
hairs, which are distinctly knobbed, some apparently with a slight 
tendency to divide at the truncated ends. The margin is almost 
squarely incised at the junction of the segments, and from the 
incision springs a short spine; or sometimes two, one longer than 
the other. 
“his insect apparently suffers from a dipterous para- 
site, as on boiling some of the old females with egg- 
masses | found the empty puparia of a dipteron, similar 
to those I had previously found with Dactylopius. These 
puparia are chestnut-brown, subcylindrical, rough, with 
minute bristles or prominences, and show at the pos- 
terior extremity a pair of rather long spiracular horns, 
widely apart and diverging, with their ends bifid. 
Pulvinaria urbicola, n. sp. 
On the stems and under sides of the leaves of Capsicum, in 
Kingston, Jamaica; attended by ants. September, 1892. 
@. Length, including ovisac, over }in.; width less than } in. 
Ovisac white, depressed, somewhat inclined to be longitudinally 
ribbed, parallel-sided, fairly firm. Scale shrunken so as to be 
broadly oval, olivaceous brown. A specimen found later (Dec. 
18th) has the ovisac 9 mill. long and 2 mill. broad, distinctly 
ribbed.
