barred with black, and resemble flying flowers. Every gradation of 
stridulous note, from the harsh fiddle-scraping of Decticus and Ephip- 
pigera to the feebler pipes of Phaneroptera and Conocephalus, combines 
to swell the not unpleasing discord, and to impress the mind with the 
idea of incalculable numbers and inexhaustible variety. The most 
barren spots have also their inhabitants; the species of dipoda delight 
in basking on the hot sand of the shores, or on the rocks, and may be 
turned out from every clump of sea-spurge or Cineraria. Many species 
were still in the larval state at the time of my visit, and hence the 
following list can scarcely be complete, but I do not think the omissions 
aremany. Beyond a very few notices in Fischer’s “Orthoptera Europza,” 
no special attention seems to have been given to these insects in Corsica. 
I have followed the nomenclature and arrangement of that very com- 
plete work, because I know nothing better. 
Labidura gigantea, Fab. Running about the quays of Ajaccio at 
night; common. Jorficula auricularia, L. F. pubescens, Géné. On 
trees ; Campoloro. 
Blatta marginata, Schreb. Under stones, sea shore. B. germanica, 
L. In houses. B. livida, Fab. Taken commonly, by sweeping. Pe- 
riplaneta orientalis, L. Several exotic species (introduced), said to be 
found in Sardinia, I did not meet with. 
Mantis Spallanzania, Rossi. Rare. IW. religiosa,L. Less common 
than in 8. France. 
Bacillus gallicus, Charp. One full grown in the Botanic Garden 
of Ajaccio. Young larve occasionally. 
Gryllotalpa vulgaris, Latr. Banks of the R. Gravone. It resem- 
bles individuals from the banks of the Rhone at Tarascon. Smaller 
than the British insect, and the fore legs differently toothed. Another 
species? Mogoplistes brunneus, Serv. Under stones, rare ; very delicate 
and difficult to preserve. Cécanthus pellucens, Scop. Common near 
Ajaccio. Trigonidium cicindeloides, Serv. Shining black, with red hind 
femora ; a most beautiful little cricket, and peculiar to these islands. 
Campoloroand Biguglia. Gryllus campestris, LL. Banks of the Gravone. 
Liphippigera rugosicollis, Serv. Campoloro. Stridulates loudly ; 
bites severely ; ¢ fawn-coloured, 2 green. The spp. are distinguished 
with difficulty. They are best preserved in spirit. Z. vitiwm, Serv. 
Less common than the preceding. Phaneroptera macropoda, Burm. P. 
falcata, Scop. Conocephalus mandibularis, Charp. Xiphidiwm fuseum, 
Fab. Locusta viridissima, L. Thyreonotus corsicus, Serv. Thamno-
