Genus PKOTAXIS, g. n. 



Type, P. fulvescens, Gahan. 



Range. That of the type species. 



Head with the front short aud broad, sloping gradually from 

 the vertex ; the clypeus slightly depressed, marked off from the 

 front by oblique sutural lines, extended anteriorly beyond the base 

 of the mandibles, membranous only at its front edge ; labrum 

 transverse ; mandibles moderately long, gradually incurved at the 

 apex ; gula produced so as to form a distinct inentigerous process ; 

 eyes transverse, subfinely facetted, emarginate in front. Antennae 

 inserted under a slight ridge on each side of the front close to the 

 base of the mandibles and at a short distance in front of the eyes, 

 their condylar foramina facing outwards ; reaching to the apical 

 fourth of the elytra in the c? ; first joint rather long, slightly 

 curved, gradually thickened up to the apex and there somewhat 

 abruptly expanded behind in the form of a short blunt process ; 

 third joint much shorter than the first and distinctly shorter 

 than the fourth ; fifth to tenth subequal, each very slightly longer 

 than the fourth ; sixth slightly, seventh to tenth more strongly, 

 angulate anteriorly at the apex. Prothorax transverse, feebly 

 convex or almost flat above, rounded at the sides and somewhat 

 constricted at the base. Mesonotum with undivided stridulatory 

 area. Elytra gradually narrowed backwards from the shoulders, 

 each obtusely pointed at the apex and furnished above with three 

 or four feeble costae. Legs moderately long ; femora rather stout, 

 fusiform-cylindric ; tibiae, especially the hind pair, somewhat 

 expanded at the apex, each carinate along each side close to the 

 ventral face ; tarsi rather short and broad, the first joint of the 

 front and middle tarsi scarcely longer than the second, that of 

 the hind tarsus almost as long as the second and third united ; 

 third joint completely bilobed ; claws not widely divergent. 

 Front coxae somewhat prominent, their acetabula widely open 

 posteriorly and strongly angulated on the outer side ; the inter- 

 coxal process very narrow in the middle and only slightly wider 

 posteriorly. 



87. Protaxis fulvesceus, sp. n. 



Head, prothorax, scutellum and elytra fulvous ; antennae, legs 

 and underside, the prothorax excepted, black ; the antennae 

 faintly and the body and legs rather densely covered with grey 

 pubescence. Head densely and rather finely punctured and 

 faintly pubescent. First joint of antennae densely punctulate, 

 obsoletely carinate in front: eleventh joint very little longer 

 than the tenth, furnished at the end with a short pointed 

 appendix. Prothorax very feebly convex or nearly flat above, 

 obtusely marginate at each side, with a short delicate fringe of 

 grey pubescence projecting from each margin ; the flanks also 

 clothed with grey pubescence ; the upper surface densely covered
