marks as Macroptera and Brachyptera ; the wings and 

 elytra being either equal in length or shorter than the 

 abdomen. Moreover, the species is liable to much 

 variation in colouring. Probably insular and conti- 

 nental forms somewhat differ in these particulars.

Frons of the male dark brown or black. Crown 

 black. The rest of the colouring, from description, 

 does not seem much to differ from the preceding 

 species. I have not seen specimens sufficiently distinct 

 in character to require a figure. Mr. Edwards says 

 E. acuminatus is common. 



Euacanthus interruptus is accused of doing injury to 

 the English hop-vines. Personally I have nowhere 

 met with the insect in such abundance as to lead to 

 the supposition that it can commercially affect us. It 

 is largely spread over Great Britain, and it finds its 

 food on many different plants. 



In July I saw many infesting the furze bushes (Ulcx) 

 on the tops of the high cliffs near Freshwater. I 

 have taken them also on the rushes at Haslemere, 

 and on the chalk downs near Marlborough. They occur 

 also on the shores of Milford Haven, and other places. 



The larvaB are of a singular form, and somewhat un- 

 couth, with their dark eyes and erect banded bodies. 



The imago is dimorphous, often brachelytrous, or 

 even without wings. It may be taken in July and 

 August.
