THE CANADIAN ENTOMOLOGIST. 269 



Costa of fore wings, dark mouse colour. Inner two-thirds of wing 

 the same, excepting a prominent black spot in discoidal space, sur- 

 rounded by a reddish-brown yellow ring, and outside of this a semicircle 

 of same colour. Hind margin has a linear border of ground colour. 

 The interspaces of hind margin contain a dash of reddish-brown yellow 

 extending as far as discoidal space in upper three interspaces and paral- 

 lelling downwards. These dashes form practically a broad band cover- 

 ing outer third of wing, the nervures of ground colour only showing 

 between them. The outer end of these dashes contains a black arrow- 

 head, small at top interspace, and increasing in size in lower interspaces. 

 The inner end of these dashes contains a black dash, increasing in size in 

 lower interspaces. 



The hind wings duplicate these markings, with the following excep- 

 tions: The discoidal spot is much less prominent. The semicircle out- 

 side of it is missing. The linear border is also missing, the reddish- 

 brown yellow extending clearly to margin. 



The under side of both wings is the same as upper side, excepting 

 that the ground colour is much lighter, and the yellowish portions 

 suffused somewhat with ground colour. The discoidal spots are more 

 prominent owing to the lighter shade of the background, rather than to 

 any change of their own. 



The general appearance is close to Eurybia Jemi/ui, Hew. 



Described from two specimens in my collection, secured by my 

 collector, Mr. William J. Gerhard, at a point five days north from 

 Cochabamba, Bolivia. In all the collections examined, including the 

 largest collections in this country and in England, only one of this 

 species was found, that being in Mr. Hewitson's collection, unnamed. 



THE COLORADO POTATO BEETLE IN ENGLAND. 



Although the announcement that the Colorado beetle had been 

 discovered at Tilbury Docks (near London) must have given rise to 

 some apprehension on the part of agriculturists in general, and potato- 

 growers in particular, we are able to state, as the result of inquiries, that 

 there now exists no cause for alarm, the prompt action of the Board of 

 Agriculture having succeeded in exterminating, so far as is possible to 

 judge, the dangerous insect. Little, if any, damage was done by this 

 visitation, which seems to be the fust for fifteen or twenty years. Tin- 

 land around Tilbury Docks is not agricultural, and if potatoes are
