to the posterior edges ; another considerable part of the wings is likewise scarlet, running from the 

 body to the middle, and from thence to the abdominal corners ; the posterior and anterior edges being 

 black. Legs dark green, almost black, and variously spotted with yellow : the fore and middle ones 

 having a spot on each femur and tibia, the hinder ones having three on each femur, and two on each 

 tibia. 



GRYLLUS (GRYLLACRIS) TESSELATUS. 



Plate XLII. fig. 3. 



Order : Orthoptera. Section : Saltatoria. Family : Gryllidse. 



Genus. Gryllus (Locusta), ia<W«We. Subgenus: Gryllacris, Serville. 



Gryllus (Gryllacris) Tesselatus. Fusco-fulvescens, alis diaphanis nigro undique tesselatis. (Expans.

Habitat : Island of Johanna, near Madagascar. 



General colour brownish yellow. Head smooth. Eyes rather prominent and dark brown, with a 

 whitish streak between them. Antennae the length of the insect. Mouth furnished with four palpi, 

 knobbed at the extremities. Thorax margined, and a little indented. Scutellum, which is not seen 

 when the wings are closed, whiteish and triangular. Tegmina thin, and fuU of tendons. Wings nearly 

 diaphanous, and prettily speckled with cross marks in a zigzag manner. Legs strong ; the hinder ones 

 formed for leaping. Tibiaj armed with spines, pointing downwards ; those on the hinder ones being 

 shortest. Abdomen very singularly formed, the last segment terminating in a kind of horny beak which 

 curls inwards, but widens and expands at the extremity, so as to appear like a knob or club ; and close 

 above it, but on the upper part of the abdomen, are four filaments about the size of the antennae ; two 

 of them being longer than the other, extending to the very extremity of this part. (See Fig. IV.) 



The antennae in this subgenus are of very great length, being many times longer than 

 the whole body. The specimen, therefore, figured by Drury was evidently mutilated in 

 these organs.
