strongly compresso-foliaceous almost wholly cristate, more highly 

 elevated above at the middle summit ; the superior margin of ante- 

 rior half abruptly elevated, in front vertical undate and above 

 strongly unisinuate-subuudate ; the posterior half backward gently 

 deflexed undulate and near the apex concave, posteriorly lengthily 

 extended beyond the apices of the hind femora and acute ; superior 

 margin of crest marked with fuscous, viewed from above sinuous ; 

 anterior [process below arcuate produced above the head, the apex 

 little straight excised ; lateral lobes of pronotum posteriorly 

 Insinuate, posterior angles elongate, obliquely extended outward 

 and rounded. Elytraoblong subacuminate ; wings fully explicate, 

 extended backwards to the pronotal apex. Anterior femora com- 

 presso-foliaceous, superior margin subtrilobate, below quadrilobate, 

 or the two middle lobes fused in one ; middle femoral carinae above 

 slightly undulate, below compresso-ampliate, sinuate, and bearing a 

 small apical lobe ; posterior femoral carinae above subentire, 

 minutely serrulate, marked by small fuscous dots, and near the 

 apices terminating in acute denticle ; inferior carina of external 

 pagina strongly compressed-iucrassate, viewed from above little 

 undulate and bearing a strong projecting median lobe ; ventral 

 margin entire or indistinctly undulate and marked with fuscous ; 

 first articles of posterior tarsi equal in length to tin- third, the first 

 and second pulvilli minute, the third distinctly longer. Colour, 

 greyish-rufescent, sparingly speckled with fuscous, the tibiae in- 

 fuscated toward the apices, joints and apices of tarsi black. 



Length of pronotum, $ 17"2 mm. ; height at middle, 7 mm. ; 

 posterior femora length, 7 mm.

Body smoothly granulose ; eyes globose ; face strongly retreating ; 

 vertex strongly obliquely produced in an elongate cephalic process, 

 cuspidate at the apex, viewed from above longitudinally sulcate, 

 sides entire ; vertex, between the eyes forward broadly fossulate, 

 middle not carinate. Antennae long, longer than the head, inserted 

 below the eyes; frontal costa narrowly sulcate, superior paired 

 ocelli placed between the lower third of the eyes ; median ocellus 

 placed far below the eyes. Pronotum anteriorly truncate, posteriorly 

 lengthily acuminate-subulate, extended be fond the femoral apices ; 

 dorsum narrow between the shoulders, deplanate ; median carina 

 low, scarcely elevated ; anterior carinae short parallel ; humeral
