or blotches of the same, frequently in opposition to each other, the 

 pale upon the dark ground, or vice versa. The varieties to which 

 some of the species are subject are almost infinite, and authors who 

 have taken colour alone as their guide in their attempts to describe 

 the species, have consequently failed, and described the different 

 varieties as so many species, as may be seen by a reference to my 

 Catalogue. Their larvae are carnivorous, and subsist upon Aphidae ; 

 they are, in common with the imago, very active ; provided with six 

 triarticulate legs; their body is elongate, diminishing to a point 

 behind, which is provided with a fleshy tubercle, answering the pur- 

 pose of a seventh leg, and by which the pupa are eventually 

 suspended ; some are scaly, others pilose, or tuberculate, and some 

 smooth and velvety behind ; their colours are various : the imago is 

 produced in from twelve to fifteen days ; and several broods occur, the 

 first appearing early in the spring ; but many of the species hyber- 

 nate beneath the bark of trees : they frequent trees and plants, and 

 occasionally appear in countless multitudes: from the joints of the 

 thighs a yellow mucilaginous narcotic fluid, of a disagreeable smell, 

 exudes when they are laid hold of; and which in the Co. 7-punctata 

 has been held as a specific for the tooth-ache. The genera of which 

 the indigenous species consist may be thus externally distinguished.

Antennas very short, slender at the base, the apex with a capitate-clava, the 

 capitulum somewhat solid and acute. Palpi maxillary short, rather stout, 

 with the terminal joint thickened and obliquely truncate ; head deflexed : 

 thorax broadest in the middle, margined, very short, truncate, the hinder 

 angles rounded: elytra ample, with a broad dilated margin: body hemi-
