the insect walks slowly away; though it continues to become 
still more hard and solid for two or three days. 
It places its eggs among, or in the vicinity of the plant lice on 
which its young are to feed. These eggs may frequently be 
noticed on the chafl' of the wheat ears, and adhering to the slen- 
der, hair-like pedicels of oats, in little irregular masses of a bright 
yellow color. From them hatch the larva;, which have been de¬ 
scribed above. 
.... ^‘no-marked Coccnclla measures from 0.20 to 0.25 ic length and 0.15 to 0.20 in 
Width the smaller sued individuals being males. Its body is nearly hemispherical, with the 
surface smooth, shining and minutely punctured. The head is white, changing after death

« »»g covers are bright orange red or frequently firey red, but change after death to ycl- 
ow, less pale than that to which the white parts change. Their anterior edge adjacent to 
the scutcl is whi o, this color being gradually shaded into the orange ground. On the suture 
is a slender black lino running its whole length. At the anterior end of tl.o suture is a 
black spot, common to both wing covers and embracing the scutcl in it, anterior end. This 
spot ,s quite variable in its form, being sometimes broadest across it, middle and dinmond- 
s aped oi with its posterior half rounded, sometimes broadest posteriorly and then spear- 
shaped or broadly egg-shaped, sometimes yet more developed and broadest at its hind end, 
forming then a triangular spot as wide as it is long. On each wing cover are four other black 
roundish spots, an anterior, an outer, an inner and a posterior one, the two first smaller and 
o othei two larger than the common spot. The anterior spot is placed at a distance equal 
to its width from the anterior edge and more than twice ns far from the outer edge, and it is 
more round ,n its form than either of the other spots. The outer spot is usually of the same 
size w, h the anterior one and is more or less triangular in its form. It is placed at a third 
of the d,stance from the base to the tip of the wing covers, and less than its width from the 
outer edge. The inner spot is situated farther back than the outer one, but is forward of the 
middle, and less than its width from the suture. It is round, or short oval and transverse. 
T 10 hind spot IS similar in sizo to the one last mentioned, and is twioe ns far from the suture 
as from the outer edge. It is transverse and in form of a very short band. The wings are 
smoky hyaline, becoming clear towards their bases and having the veins here red. The back 
underneath the wing covers is black with red bands on the sutures, each side being also 
broadly red with a longitudinal row of black dots. The under side and legs are black, with 
a small white spot upon each of the corners of the hind breast.

of its wing - covers, and lias hence ha<^ the rare fortune to escape
