﻿AuADUS may be at once separated from the Tingidae by the 

 greater length of the second joint of the antennae, by the elytra 

 not covering the abdomen, by the tarsi of two joints, &c. ; and 

 from Aneuriis (fol. 86), by the shortness of the terminal joint 

 of the antenna?, the strong nervures, slender rostrum, S:c. 



From their depressed form it is most likely that, like 

 Aneurus, they reside under the bark of trees ; and from their 

 variegated and plain colours they are not easily detected : but 

 as they never occur I believe in any abundance in this countr}', 

 their economy is not well known. 



The genus has never before been recorded as British, al- 

 though Stewart in his " Elements" mentions some of the 

 species. The following are inhabitants of this Island. 



1. A. depressus Fah. Wolff, tab. 13./ 123. 



This is the most common of the species ; I have found it 

 twice at Darent Wood, Kent : it is a very sluggish insect. 



2. A. corticalis ? Linn. — Curtis Brit. Ent. pi. 230. 



Mr. Dale tliinks he took the female figured at Hurne, in 

 Hampshire. 



Although Linnaeus does not notice the pale termination of 

 the third and fourth joints of the antennae, nor has Wolff re- 

 presented them, I am disposed to think that they are subject 

 to vary in this respect, or it may be a sexual mark ; and 

 whether Schellenberg's Corcus spinigcr be allied to this or to 

 A. dcjnrssns, I cannot ascertain, not having the work. 



3. A. Betulai Lifin. — DeG. 3. /. 1 5. J. IG, 17. 

 Found on the Birch. 



Tlie plant is Orchis mascula (Early Orchis).
