ORTHOPTERA IN THE ISLE OF WIGHT. 255 



tains of Southern Italy, F. tari/innii, Brunner, in which the win.Efs 

 are wanting, and the elytra arc rounded posteriorly; in these two 

 females, as in the normal /•'. anriodaria, the elytra are emarginate 

 behind. /•'. tarf/ionii is only distinguished from /•'. aiiricnlaria by the 

 absence of the wings and rounded hinder margin of the elytra. 



Mr. Donisthorpe took another curious F. auricnlaria at Ryde on 

 August 25th ; it is a normal male, but with the right branch of the 

 forceps simple, of the same shape as the forceps of the female ; this is 

 a phenomenon not very rare in earwigs and is often called gynandro- 

 morphism, but, in all the cases that I have examined, the abdomen 

 consists of nine visible segments, which is the normal number of the 

 male, only seven being visible in the female ; I am of opinion that 

 this is not true gynandromorphism, but merely poor development of 

 one branch, due to an accident or to insufficient nourishment ; in all 

 earwigs the forceps vary considerably in shape, and are often deformed 

 or distorted by various circumstances. 



For/kida Icsnei, Finot, we found in two localities ; the first was the 

 Underclifit" near Blackgang, where Mr. Donisthorpe took a very dark 

 female by sweeping ; I swept hard for nearly two hours, but only 

 found two more females ; at the end of the day, when returning to our 

 bicycles after bathing, I took a male by a casual sweep of my net 

 among thistles, just as we were leaving the locality ; in the chine at 

 Blackgang, immature specimens abounded in the thick herbage by 

 the brook, but I was unable to tell whether they were F. auriodmia 

 or F. lemei. The second locality was a bed of nettles by a hedge at 

 Freshw^ater Bay, where Mr. Donisthorpe found them commonly, and 

 Ave took a good number of individuals in the nettles only, the -w^hole 

 length of one hedge. 



Fctnhia jMnwri, Stephens, I found common enough all along the 

 coast ; we took it sweeping at Alum Bay, Yarmouth, Compton Bay, 

 Blackgang, on the Undercliff at St. Catharine's Point, and also at 

 Boscombe, where Major Robertson took a very dark specimen of the 

 form nviripes, w'hich is the northern race. This little cockroach varies 

 considerably in colour, from nearly black, {lu'i/ripcs, Steph.), which is 

 by no means uncommon in England, to yellowish, almost testaceous, 

 as in Spain. 



F. lapponica, Linn., occurs in Parkhurst Forest, where ]\Ir. Donis- 

 thorpe swept one on August 7th. Very immature larvjB of one species 

 were abundant among the dead leaves and twigs in the Forest, but 

 these, from their pale colour, I think were immature F. livida, the rare 

 species, but we were unable to find an adult specimen. 



Among the true grasshoppers, I found Mccostctlius //rossus, Linn., 

 numerous, as usual, in Denny and Matley Bogs in the New Forest ; 

 on August 20th, I went over to Brockenhurst, for a day in the bogs 

 with Mr. W. J. Lucas, but the weather was so abominable that we 

 were quickly driven home ; still, I took three or four M. i/mssiis, and 

 returned two days later in fine weather, to find it numei'ous ; it is 

 quite the handsomest of our indigenous Acrid iodea, and like many 

 continental species it takes readily to flight. The fact that so 

 conspicuous an insect was overlooked for so many years, though 

 numerous in the bogs where it does occur, encourages one to hope 

 that one day its relative and rival in beauty, I'arajdeums alUaceus, 

 Germar, may be taken in this country ; it occurs on the continent in
