Descriptions of New or Little-known Orihoptera. 419 



on the outer face, the upper part of which is only very indistinctly 

 pinnate ; there are no traces of auditory organs on the fore tibiae, 

 which are armed with strong spines, and bear, on the upper side, 

 in addition to the apical, two conspicuous ones situated respectively at 

 the first and second thirds of the length ; in the intermediate tibiae 

 the position of the spines is 4 and 3 ; in the posterior 6-4. 



The species for which this genus is founded is, in all likelihood, non- 

 sal tatorial, and is easily recognised by the very roughened surface 

 of the whole head, especially in the anterior part. 



BOCHUS CONTEMNENDUS, 11. Sp. 



Fuscous, with the ventral part of the abdomen, the sides of prono- 

 tum and the knees lighter ; antennae fuscous ; vertex deeply and 

 closely punctate ; a small flavescent ocelliform macule in front of the 

 fastigium, but less marked in the $ ; clypeus, base of labruiu and 

 anterior part of genae very roughly rugose punctate, mandibles short 

 but very powerful, almost as broad as long, and powerfully dentate ; 

 pronotum and abdomen very finely aciculate, almost smooth ; legs of 

 the visual shape and with the usual spines, which are more developed, 

 however, in the anterior than in the posterior ; the hind tibiae are 

 slightly curved ; the very short ovipositor is almost vertical. 



Length of body 35-36 mm. ; of pronotum 10 mm. ; of hind femora 

 19 mm. ; of hind tibiae 17 mm. ; of ovipositor 3 mm.

FAKU, n. gen. 



The species for which I propose this genus is distinguished from 

 Nasidius by the much lesser development of the head and mandibles ; 

 the latter being short, robust, sharp at apex, strongly dentate and very 

 much like those of the females of our South African Mimnermi. From 

 Bochus it is distinguished by the more dilated proximal part of the 

 hind femora. The supra-anal lamina is crumpled in my example, but 

 the cerci and sub-genital lamina are as in Nasidius. 



FAKU MINAX, n. sp. 



$ . Fuscous bronze sprinkled with pale flavescent; mandibles 

 fulvous, black at tip ; head a little wider than the pronotum, but 

 robust and slightly ainpliated in the genal part ; vertex of the normal 

 shape, fastigium with the usual carination, clypeus raised in the centre 

 as a continuation of the fastigium, but not developed in a tubercle, 

 the geuae are simple, and only the clypeal part is very slightly
