 extremities rounded; two small indentations on either side, from each of 

 which a fine transverse line runs up the side, merging into the dorsal carina. 

 Length, ^ inch. Under-surface very convex, legs and antennae well developed ; 

 the lines from the marginal indentation outlined on the ventral surface with 

 a white secretion. The whole marg'n fringed with short irregular setse or 

 hairs.

This widely distributed species, originally a native of Europe, is now 

 recorded from the United States, and from Australia, by Maskell, upon 

 gooseberry twigs from Melbourne, Victoria. In Mis. Fernald's catalogues, 

 its food-plants include the grape vine, peach, mulberry, phim, nectarne, 

 and Japanese quince. 



" Adult female dark red to reddish-brown, semi-globular, sometimes 

 elongated; epidermis smooth, showing some minute transverse wrinkles. 

 Diameter, t,; to i inch." (Maskell). 



Newstead says : " Adult female dusky yellow, dorsal area usually paler, 

 with from eight to nine transverse bands foimed of blackish and more or 

 less distinct confluent spots. After jjarturition, the blackish markings dis- 

 appear and the colour changes to light redd sh-brown or dark castaneous. 

 Form elongate ovate and h'ghly convex or rarely short ovate and almost 

 hemispherical."
