﻿THE PSEUDOTRIMERA. , 229 



Some of the species, sueli as IS-jmnctata and 19- 

 punctata, frequent reedy or marshy places; these are 

 more elongate than the rest^ and, when alive, of a 

 pinkish tone, with many spots. Others, obliterata 

 (bearing an M-like mark on its thorax), hieroglyphica 

 (varying to deep black), 18-guttata, oblongo-guttata, and 

 ocellata (the largest, and conspicuous for the yellow 

 rim surrounding each of its spots during life), are pecu- 

 liar to fir-trees; and a few, especially the delicately- 

 dotted lemon-coloured 22>-punctata (Plate XVI, Fig. 5), 

 and the little, convex Micraspis 16-punctata, frequent the 

 seaside. 



Chilocorus and Exochomus, both usually found on fir- 

 trees, present much the appearance of the Cassididcv, 

 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 tibise are armed with 

 a tooth in the middle. In them, and in all the preced- 

 ing 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 sometimes 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 ob- 

 served to feed upon small Aphides, and to be entirely 

 clothed with a white cottony secretion. 



Lastly, the reddish species of Coccidula (one of which, 

 scutellata, has its elytra spotted with black) frequent
