﻿the length of the basal johit of the aiUenmr, the latter by its 

 shortness, we shall find a «);reat number of species that difier 

 very materially from ihem: the insect figured for instance has 

 the antennte and head of A.siraca, but die neuration of the wings 

 and the form of the legs agree better with Delphax, as do 

 those also of A. dubia : it will therefore form a very good sub- 

 genus, being distinguished from die type A. davicornis by its 

 simple anterior legs, and a great dissimilarity in the superior 

 and the ample size of the inferior wings; the 2 first joints of 

 the antenna- are also of nearly ecjual Inigth : another group I 

 have lately characterized in the Entomological Magazine un- 

 der the name of Criomoij)hus. 



In dissecting these insects I discovered on each side the 

 labrum, or rather perhaps the clypeus, an acuminated horny 

 lobe: they covered apparently the base of the mandibles or 

 maxilUv, and are common to the insects of this division. 



The following species have been taken in Britain. 



1. A. davicornis Fcib. — Coqiicherfs Icon. pi. 8./ 7.1 

 Length nearly 2 lines. Piceous, antenna^ head and ante- 

 rior portion of thorax ochreous ; superior wings variegated 

 with brown at the tips, the nervurcs slightly tuberculated and 

 having series of short bristles: inferior wings minute; legs va- 

 riegated with brown, anterior dilated, brown with a few 

 ochreous spots, the tip of the tibia of the same colour. 



Grassy places, end of April, in a clover field at Henstead, 

 Suffolk, J. C. 



2. A. dubia Crcut.—Panz. 35. 20.— grisea Lat. 



2§ lines long. Smooth, pale ochreous, robust; eyes black, 

 2nd joint of antennae nearly as long as the 1st, both brown at 

 the tips, a brown line on each side the thorax : superior wings 

 shorter than the body, immaculate ; inferior none ; abdomen 

 variegated with brown. 



SOth July and beginning of Sept., on rushes near Black 

 Gang Chine. 



3. A. pulchella Curt. Brit. Ent. pi. 41-5.— Allied to D. cras- 



sicornis Fab. and Panz. 35. 19. 



I first discovered this pretty insect with the foregoing spe- 

 cies, and Mr. Dale having taken Uiem in company, imagined 

 that A. dubia might be the pupa, but I think it may be die 

 female of./, pulchella, lor I have never seen a male of it, whilst 

 of this species I cannot find a female. It has aUo been found 

 by Mr. Dale in a damp situation near the sea at Charmouth, 

 as well as another pretty species on reeils at the Peat Pits, 

 Weston on the Green, near Oxford, together with a 5ih hav- 

 ing a very faint mark on the wings. 



The beautiful Plant is Latlnjnts Nissolia (Crimson Grass- 

 vetch), gathered at Puckaster Cove in the Isle of Wight, and 

 communicated by Charles Vine, Esq.
