ANNUAL REPORT OF NEW YORK 
APHIS. PARENTHESIS COCCINELLA DESCRIBED. 
slender hair-like prickles forms a wrinkled mass around the tip 
of the pupa, similar to that of the Nine-marked Coccinella already 
described. 
The pupa is colored and spotted very similarly to that of the 
Nine-marked Coccinella. It is dull citron yellow with an orange 
red spot on the outer end of the first and fourth segments of the 
back, and a row of black spots each side of the middle of the back, 
which are often confluent with each other forming two stripes. 
The flattened first segment of the thorax has four black spots on 
its anterior edge which are somewhat confluent with each other, 
and four others on its hind edge which are more distinctly sepa¬ 
rated, the outer ones being in contact with a similar black spot 
on the sheaths of the wing covers, which sheaths also have the 
margin and tips more or less black and a large black spot in their 
centre, which is often confluent with the black margin. 
But this pupa is quite variable in its colors, sometimes having 
the whole of the first segment of the thorax black, except a cloud 
across its middle, and the abdomen black, with a pale stripe along 
the middle, and a more slender one on each side of it, and the 
outer ends of fourth and fifth segments pale, thus approaching in 
color the pupa from which a Five-marked Coccinella was obtained. 
Yet these dark colored pupae yield as bright colored and perfect 
insects as the lighter ones. Pupae very probably occur, from 
which it will be impossible to decide whether this species or one 
of the others will come, although they are so readily distinguish¬ 
ed when they arrive to their perfect state. 
The Parenthesis Coccinella is oval and more than a third longer than wide, measuring 0.16 
to 0.20 by 0.11 to 0.13. Its surface is shining and is closely and minutely punctured. The 
head is black with three white spots on the front, the middle one diamond-shaped and usually 
prolonged upward in a short line, the lateral ones triangular and placed at the inner sido of 
the eyes, their inner angles being sometimes confluent with the lateral angles of tko middle 
spot, the three spots when thus united forming a figure resembling the head of a trident, 
from which circumstance Mr. Kirby named this species tho Trident Coccinella. These spots 
on the other hand are sometimes much smaller, tho middle one merely a short white lino or 
even entirely wanting, and tho lateral ones a small lunulc or a moro dot cn tho margin of the 
eyes. The lower edge of tho head and the lip aro livid yellow or testaceous. Tho mandibles 
are white and the pulpi testaceous with blackish tips. The antennse are testaoeous, their 
basal joint black on the upper side and their tips blackish. The thorax is black, margined 
with white on the front and sides, this margin being usually wide but sometimes narrow, 
widened on tho hind angles, where its end is obliquely or concavely cut off, tho inner side of 
its end being often prolonged into an aoute angle which points towards a similar angle jutting 
baokward frouj the front margin, thus tending to cut off a large round dot from eaoh sido of 
the black portion of the thorax. The front margin in the middle of its hind side is also 
always prolonged backwards into a short white stripe which narrows baokwards and usually 
reaches halfway to a whito spot which is placed on tho bind margin, this white spot being
