nerve just above the apex, about IJ times as great as the distance between the 

 branches of the furcation measured on the marginal nerve, the distance between the 

 latter and tlie outer branch of the lower furcation about equal, measured as above ; 

 nervules short, brown. Legs fuscous- white, or yellow-white ; thigh.t : 1st pair with 

 a broad black, longitudinal streak down the upper-side ; claws blackish. 



Abdomen black, genital plate yellow, sparingly clothed with short, pale hairs, 

 anterior margin convex, sides produced into a long tooth or tongue-like piece, 

 reaching to beyond the apex of the processes, the latter dark brown viewed from the 

 side, about three times as high as broad at the base, outer margin convex, inner mar- 

 gin slightly concave. 



Stimmer brood. — S orange-yellow. Crown, margin and pronotum as in the 

 above. Legs yellow. Abdomen green or yellow, with the last two or three of the 

 segments sometimes black in the middle of the upper-side. All the other characters 

 as in the overwintered examples. Length, I5 line (Paris). 



Ova orange-yellow, longish-oval or fusiform, each set on a peduncle about 2\ 

 times its length, disposed irregularly, singly, or in pairs on the upper- or under-side 

 of the leaves of the samphire ; as they approach maturity, the base assumes a red- 

 dish-orange colour, and they may frequently be observed waving from side to side, 

 or swaying backwards and forwards. When close on hatching, they become entirely 

 of a dull reddish-orange colour, and the peduncle is bent down until it touches the 

 surface of the leaf, where it remains until the young larva has made its exit. 



Larva orange-yellow throughout all its stages, somewhat oval, flat, sluggish, 

 with a narrow border of glittering white hairs. 



Nymph pale orange-yellow, or with the abdomen green, flat, entire margin with 

 a border of glittering white hairs, longest at the extremities, where they appear 

 pectinate. Head broad, anterior margin notched in the middle, extremities rounded, 

 disc with four short, longitudinal channels between the eyes, not reaching to the 

 anterior margin narrowly rounded, almost in a line with the anterior margin of the 

 head. Legs pale yellow. 



This species was originally taken on CritJimum mnritimitm by Dr. 

 A. Puton, at Eoscoff and Morlaix (Finisterre), towards the end of 

 June ; and, from Dr. F. Low's description, made from specimens sent 

 to him by the discoverer, I believe these to have been of a newly- 

 hatched brood. Here it has been taken in all its stages, at Anstey's 

 Cove Eocks, near Torquay, by P. H. Gosse, Esq., F.E.S., who most 

 kindly forwarded me many examples, from which the above description 

 I has been made, together with the following vivid note of his suc- 

 cessful search : 



" Anstey's Cove, in the neighbourhood of Torquay, is divided into two by a 

 projecting promontory. The northern of the two, which is the nearer to Babbi- 

 combe, has a fine beach of white limestone pebbles. At the rear, the limestone has 

 fallen from the lofty cliffs in great cubic blocks, as big as a small cottage or a railway 

 carriage, which now lie on the shingle, or on the sloping debris. From crevices in 

 these blocks, from beneath their bases, and from the ground between, even from 

 amidst the white pebbles, the Samphire is now shooting up (April, 1882) in dense
