This genus contains about twenty species, which are widely distributed 

 in Europe and North America ; one or two are found in Northern Asia ; 

 they are, as a rule, of a more oblong and looser form than the greater 

 part of the other Cocciiiellidie. H. varierjata is a very variable species, 

 and some of its varieties appear to be found in Northern Africa, Senegal, 

 and India, as well as in more northern climates. 



I. First joint of tarsi not dilated in male ; size 

 larger; elytra orange-yellow, with a common spot 



at scutellum, and six spots on each black . . . H. TREDECIMPUNCTATA, L. 

 II. First joint of anterior and intermediate tarsi 

 dilated in male {Adonia, Muls. ); size sniHller; 



elytra reddish, with variable black spots on each . H. vaeikgata, Ooeze ,-

 Battersea (Stephens); Suffolk, in flood refuse, abundant (\V. Garneys) ; Deal; 

 Hastings; near Lancaster on Arundo phragmites ; Nortlmmberland and Durham 

 districts, Meldon Park, Twizell, and Durham ; Scotland, Lowlands, rare, Solway and 

 Forth districts; Ireland, near Belfast and Portmarnock ; the species is found through- 

 out Siberia and occurs in North America as tibialis, Say.; it is very variable as 

 regards the size of tlie spots of thorax and elytra.
