GAEIEP, n. gen. 



Mentum sub-parallel, then incised at about the median part, and 

 continued as a ligular part also parallel, as long as the mentum, and 

 deeply sinuate at apex, the condyle is moderately long, sub-lateral, 

 and the labial palpi are thus inserted on the outer face of the men- 

 tum, last joint of labial palpi sub-cylindrical and very long ; maxillae 

 not robust, long, inermous, the upper lobe narrow, long, somewhat 

 oblong and surmounted by a very long, dense, not penicillate pubes- 

 cence, last joint of maxillary palps slightly swollen inwardly at 

 base, sub-truncate at tip, and hardly longer than the ultimate labial 

 one ; clypeus very strongly incised laterally above the base, expand- 

 ing triangularly to the apex which is truncate, twice as broad there 

 as at the base, very plainly tri-sinuate with the angles acute, so 

 deeply concave that the outer anterior side is quite declivous, frontal 

 part with a very high transverse lamina between the antennae ; eyes 

 very large, canthus very hairy and transverse ; pedicel of antennae 

 very long, club still longer lamellate and arcuate ( $ ) ; pro thorax 

 ampliated laterally from the apex to the slightly rounded basal angle, 

 not sinuate along the base which is slightly arcuate, and does not 

 cover the mesothoracic episterna ; scutellum very long and sharply 

 acute at tip ; elytra plainly sinuate laterally above the hind coxae, not 

 attenuate behind, plane ; propygidium slightly concave, vertical ; 

 mesosternum with a bluntly triangular process between the median 

 coxae, and separated in the $ from the metasternum by a distinct 

 suture ; anterior tibiae bi-dentate outwardly, and with slight traces of 

 a third one, outer terminal part of median ones bi-dentate, hind ones 

 also bi-dentate at apex, but having, unlike the median ones, no traces 

 of a tooth on the upper edge ; fore and median tarsi somewhat long 

 and slender, hind ones shorter and slightly compressed, hind spurs 

 (c? ) long and sharp, ( $ ) spatuliform. 



I have seen only one female example, which I picked up dead in 

 Namaqualand ; it has lost all its pubescence, and is partly bleached, 

 but I have no doubt that it is the female sex of G. patera ; the clypeus 

 is rounded laterally in front and not sinuate, at its junction with the 

 head there is a small transverse carina ; the antennae are missing ; 

 the ligular part of the mentum is not quite so elongated as in the $ , 

 but the maxillae are identical ; the prothorax is alike ; the elytra are 

 more elongated, and plainly ampliated in the posterior part ; the 

 pygidium is sub-vertical and convex ; the terminal part of the hind 

 tibiae are dilated, and the upper hind spur, the only one left in my 

 example, strongly spatuliform ; the process between the intermediate 

 coxae has no transverse suture.
