larger ports and towns. Among the native Blatta is one an 

 inch and a half in length, but rarely found in the perfect 

 winged state. Besides this there are several others, never 

 attaining to the winged state. Several species hunt their prey 

 by daylight, living upon bushes, and are exceedingly swift in 

 their motions ; all others prefer darkness. The Achetid^:, or 

 crickets, furnish nineteen species. The largest in the collec- 

 tion is about one inch, the smallest less than one-quarter of an 

 inch in length. Most of them live in fissures of the ground, 

 under stones, &c, but several species, distinguished by much 

 reduced posterior wings (sometimes altogether wanting) , live 

 upon trees and shrubs, enlivening the surroundings with their 

 exceedingly penetrating chirp. Of tree crickets, gifted with 

 excessively long and thin antennae and large wings, some very 

 large ones are found, viz., above two inches in span, and the 

 antenna? three to four inches long. They inhabit small hollows, 

 lined with a kind of coarse silk, and appear to be carnivorous. 

 Of Gri/llotalpa, or mole crickets, only two closely allied species 

 occur in watercourses and in moist situations. 



The LocrsTiDiE are represented by at least six genera. 

 Locust a contains sixteens species, most of which are rare, or 

 even very rare. The body of the largest measures one and a 

 half inches in length, the wings nearly four inches in span. 

 Another, smaller in body, attains five and a quarter inches in 

 span, and inhabits the Murray Mats, near Blanchetown. One 

 species feeds upon the native pine (Frenela), and is dis- 

 tinguished by its yellowish-green anterior wings being marked 

 with numerous black dots ; another with white spotted wings 

 frequents Melaleuca acuminata, near Ardrossan ; another, with 

 pink-coloured wings, and a flat shield-like appendage to the 

 thorax, feeds on mallee, near Monarto. But the strangest of 

 all is a species living upon some Leptospermum shrubs. Its 

 first pair of wings is narrow and of a greyish colour ; but the 

 second is large, and beautifully marked with concentric dark 

 bands. These are rolled closely together, and form then an 

 angle with the cylindrical abdomen. "When resting head 

 downwards (its usual position), it so closely resembles in form 

 and colouration a twig of the shrub, that it is almost impossible 

 to discern it, especially as its long thin legs and antennae are 

 laid close along the branch and perfect immutability is sus- 

 tained by the insect. JDecticus has been found in one species 

 only near Callington. Its posterior wings are of a beautiful 

 pink hue, while all else is green and white. Of Tetrix four 

 species are known, fairly large insects, some with very large 

 helmet-like expansions of the head. Of (Edipoda eleven species 

 are noted, some of large size, feeding upon woody plants only. 

 Acridium is represented by ten species, five of which are from
