has a great shining red blotch at the base of each of the femora, this 

 is the only species of the genus which has any part of the internal 

 face of the fore legs conspicuously coloured 1 . 



The lamellar fore margin of the tegmina is toothed 2 in both sexes, 

 probably so as to act as a stridulating organ by scraping against the 

 corresponding part of the wings.

 figs. 6, 6 a.) 



$ . Allied to H. (R.) major, Sauss., but differing in its stouter 

 and broader pronotnm, which is more broadly rounded off in front, 

 in the armature of the anterior crest of the fore coxae, which is fur- 

 nished with eight hemispheroidal yellow tubercles or callosities, all 

 arising from its inner surface, gradually increasing in size from the 

 proximal to the middle, and then gradually decreasing to the distal 

 end of the joint, and constricted at the base so as closely to resemble 

 the crushing-teeth of certain fossil fishes (Pycnodus). 



The discoidal nervure of the wings emits four branches. 



The fore tibiae have eleven teeth on the outer edge and fifteen on 

 the inner. 



Total length 85 millims. ; length of pronotum 29, greatest breadth 

 of pronotum (just behind coxal groove) 12*5, of primitive pronotum 

 at supracoxal dilatation 10, at middle of posterior lobe 6 ; length 

 of tegmina 57, to stigma 21 ; breadth of tegmina 24, of marginal 

 field 8 ; length of stigma 3, breadth of stigma 0-9. 



Described from two alcoholic specimens. 



A dried specimen in British Museum obtained at the same time 

 measures total length 80 millims«> and has the coxal callosities 

 shrunken or less developed. 



Hab. One of the islands in Torres Straits. The specimens were 

 obtained by the Rev. M'Farlane. 



Obs. The lamellar fore margin of the tegmina toothed.

2 . Closely allied to^Lxumstcij'W.-M.., 2 > differing in its greater 



size, in its proportionally longer tegmina (which are fully equal to 



the prothorax in length), in the form of the pronotum (which is 



dilated at the setting-on of the fore legs, so as to be conspicuously 



1 These coloured femora serve, in all probability, to allure or fascinate the 

 prey. 



2 I first met with tbis curious structure of the tegmina in the Empiisid&, in 

 all of which it occurs in both sexes alike.
