The larvse in this family have an ingenious but unplea- 

 sant habit of forming their excrement into an umbrella^ as 

 in Crioceris. They are broad and flat, with short legs ; 

 beset on the sides with long setose spines, and having a 

 long fork bent forwards, and arising rather above the anal 

 orifice, by means of which they retain their excrement 

 as a shelter. The pupae, also, are broad and flat, with 

 spined appendages on the sides, and the thorax dilated, 

 spined, and covering the head. 



The transformations of C. viridis, — a very common 

 species on thistles, — may readily be observed.
