NECROl’HAGA AND THEIR ALLIES.

XVI., Fig. 5), and the little, convex Micraspis 16- 
punciata, frequent the seaside. 
Chilocorus and Exochomus, both usually found on 
fir-trees, present much the appearance of the Cassididce, 
their legs being short and retractile, their head 
hidden, and their elytra very convex, though they are 
quite flat beneath. In the former genus the tibiae are 
armed with a tooth in the middle. In them, and in 
all the preceding species, the elytra are entirely 
glabrous, but in the remainder of the family they are 
more or less clothed with a short pubescence : this is 
especially evident in Lasia globosa, — a small, round, 
convex, reddish-brown insect, variegated with many 
small irregular black spots and streaks, though some- 
times immaculate, — common on the coast. 
The Scymni are found about fir-trees and in marshy 
places; they are very small and inconspicuous, dark 
in colour, and having at most a red spot or stain on 
the elytra. The larva of one of this genus has been 
observed to feed upon small Aphides, and to be entirely 
clothed with a white cottony secretion. 
Lastly, the reddish species of Coccidula (one of 
which, scutellatn, has its elytra spotted with black) 
frequent wet places, reeds, &c., and may be known 
by their comparatively narrow shape and posteriorly 
right - angled thorax, which is narrower than the 
elytra. 
The ENDOMYCHiDiE (termed also Sulcicolles ) have 
comparatively long antennae ; the thorax impressed 
behind; the last joint of the maxillary palpi slightly 
thickened, and never hatchet-shaped ; and the posterior 
cox® wide apart. 
Two of our genera, Endomychus and Lycoperdina,
