356 Dr. J. L. IHBcock’s Third Paper on the 
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-subundate ; 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 irroduced above the head, the apex 
little straight excised; lateral lobes of pronotum posteriorly 
bisinuate, posterior angles elongate, obliquely extended outward 
and rounded. Elytra oblong 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-incrassate, 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 the 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 tar.si black. 
Length of pronotum, 5 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 beyond the femoral apices ; 
dorsum narrow between the shoulders, deplanate; median carina 
low, scarcely elevated; anterior carinae .short parallel; humeral
