edges to the centre, but still remaining apart ; below 

 the spiracles the sides are of a lighter green colour, and 

 the legs are similarly coloured. Across the skin there 

 are whitish raised clots there being two rows of these 

 to each segment and on the head are a few scattered 

 hairs. Length 13 14 lines. 



When alarmed or touched in any way, it rolls itself 

 up into a ball, and ejects a brownish liquid from the 

 mouth. When full fed it becomes of a glassy light 

 green colour, and pupates in the earth without spinning 

 a cocoon (at any rate in my breeding box). It simply 

 formed a hole neatly smoothed on the inner side in the 

 earth. 



Dispar I find everywhere in Scotland. The only 

 English locality I know is that mentioned by Stephens, 

 Darenth Wood, where it is said to be common. On 

 the Continent it is found in Scandinavia, Germany, 

 France, Switzerland, Hungary, and Russia.

Black ; clypeus, labrum, a line round the lower part of the eye, one 

 on the pronotum, two spots over the posterior co~s.se, the apical three- 

 fourths of the under side of the front coxae, and an irregular spot on 

 the apex of the two hinder ones, white. Legs with the coxse for the greater 

 part black, the rest pale yellow save the extreme apex of the hinder 

 tibiae and the tarsi, which are dull fuscous. Wings almost hyaline, 

 costa dull red ; stigma black. $ . 



Length 5f lines. 



Similar to dispar in size and form, but having 

 (apparently) the antennas and metatarsus shorter, the 

 head more opaque and punctured, and otherwise dif- 

 fering in the colour of the face and legs. The saw 

 also differs. Bare, taken near Dumfries in June.
