Ctenistes braunsi, 



Plate XVIII., fig 25. 



Elongate and sub-parallel, body sparsely covered with thin 

 ochraceous squamae ; head pyriform, rather convex, tri-foveate, 

 antennal tubercle large and a little transverse, third joint of palpi 

 stout, transverse, fourth sub-fusiform, slender, very transverse, 

 appendages of moderate size ; antennae rather short and thick ; pro- 

 thorax a little transverse, not much narrowed in front, sides very 

 little rounded, a short median fovea at base ; elytra much longer 

 than the prothorax and longer than broad, sides nearly parallel, 

 ■dorsal stria very little arcuate ; abdomen as long as the elytra, not 

 broader, sides nearly parallel, second dorsal larger than the first, all 

 the tibiae straight, thickened and a little curved at the apex ; meta- 

 sternum sulcate. 



Male : More parallel ; elytra longer, shoulders more oblique and 

 prominent ; second dorsal segment only slightly longer than the 

 first ; first and second joints of antennae larger than the others, 

 quadrate, third obconical, longer than broad, fourth to seventh a little 

 transverse, eighth hardly as long as the four preceding ones put to- 

 gether, cylindrical, ninth shorter than eighth, tenth as long as eighth 

 but thicker towards the apex, eleventh not longer but thicker than 

 tenth, and obtusely acuminate ; metasternum more deeply sulcate ; 

 posterior tibiae longer, somewhat angulate before the apex which is 

 much thicker ; tarsi, more especially the anterior ones, longer and 

 more slender. 



Female : Elytra a little shorter, somewhat attenuate at base with 

 the shoulders less prominent ; second dorsal segment much longer 

 than the first ; first and second joints of antennae similar to those of 

 the male, following ones thicker, second obconical, third to seventh 

 nearly as long as broad, eighth a little broader, transverse, ninth 

 larger, sub-quadrate, tenth still larger, sub-quadrate, eleventh nearly 

 as long as the two preceding ones and obtusely acuminate ; tarsi, 

 more especially the anterior ones, short and thick. Length 

 2*10 mm. 



This species differs very much from G. austral is, Kafir., and 

 C. imitator, Eeitt., owing to the more parallel and elongate body 

 and much thicker and shorter antennae, the third to seventh joints 

 of which are hardly transverse and the club is much shorter.
