and color like male, except inner bases of tegmina, which are green, and finely 

 reticulated like the rest. Length of tegmina, 1 in. 7 lines ; length of body, 

 1 in. 1 line.

The PhaneroptercB are the most elegantly slender of all the 

 Gryllidce, not only the small head and narrow body, but the nar- 

 rowness of the anterior pair of wings (or tegmina, or elytra) aiding 

 this characteristic appearance. The distance the hind wings pro- 

 ject behind the tips of the tegmina when at rest, and the great 

 length of the abdominal appendages of the male, are also pecu- 

 liarities. The subanal plate of the male is sometimes double, in 

 other species only bifurcate at tip ; it is usually curved upwards. 

 The shortness of the ovipositors of the female sejDarates the 

 PhaneroptercB at a glance from Locustidce. 



Like all the Phaneropterce, the posterior wings when folded 

 extend like a tail beyond the ends of the elytra or anterior wings 

 when at rest, the exposed tips being usually colored like the elytra 

 and of the same consistence, differing in these respects from the 

 transparent membranous rest of the wing. 



This species is common on young gum trees near Melbourne, 

 the tint of which it so closely agrees with that it is by no means 

 easy to detect the individuals loudly shirring or chirping on all 

 sides of the observer. 



It has not been figured before. 



Explanation of Figures. 

 Plate 119. — Fig. 1, male, natural size, in flying position. Fig. la, front view of head, 

 magnified 3 diameters, snowing absence of ocelli and form of front. Fig. lb, labrum, or upper 

 lip, showing its simple rounded edge, magnified 5 diameters. Fig. lc, one of the strong cutting 

 mandibles, magnified 5 diameters. Fig. Id, one of the slender maxilla?, showing the hood over 

 the serrated terminal joint and the maxillary palpi. Fig. le, labium, or under lip, showing its 

 terminations and palpi, magnified 5 diameters. Fig. If, head and thorax viewed from above, 

 magnified 3 diameters, showing the flat oblong disc, with the rectangularly-deflected sides. 

 Fig. Iff, hind leg, magnified 2 diameters. Fig. Ih, anterior leg, showing swelling and drum 

 cavity in base of tibia. Fig. lz, tarsus viewed from below, magnified 3 diameters, to show the 

 bilobed third joint. Fig. Ik, ditto, viewed from the side. Fig. 1/, sternum, to show the bilobed 

 middle and hinder pieces, magnified 3 diameters. Fig. Im, anal plate and appendages of end 

 of abdomen of male, magnified 3 diameters. Fig. In, elytra, magnified two diameters, showing 

 the neuration and large, clear stridulating organs at base. Fig. 2, female, viewed in profile, with 

 the wings at rest, to show the projection of the wings behind the tips of the elytra, and the 

 extension of both far behind the end of the abdomen. Fig. 2a, elytra, or tegmina, magnified 

 2 diameters, to contrast the neuration with that of the male, and to show the absence in the 

 female of the transparent stridulating spaces at base. Fig. 2b, side view of plates of ovipositor 

 and appendages at end of abdomen of female, magnified 3 diameters. Fig. 3, another specimen, 

 in the walking position, seen from above, to show the overlapping of the left elytron.
