Genus Oxyphyllum, nov. 



Allied to Xerophyllum. Vertex wider than one of the eyes, little 

 elevated, transversely carinate, middle carinate and strongly ad- 

 vanced beyond the eyes ; frontal scute! lum elongate gradually 

 widened below, divided much above the posterior ocelli, just below 

 the transverse carina of vertex between the upper part of the eyes ; 

 scutellum in i^rofile little convexly elevated between the antenna and 

 sinuate between the upper part of the eyes ; antennae filiform, articles 

 strongly elongate, inserted just between the lower margin of the eyes, 

 the distance between them wider than that to the e3^es. Pronotum 

 strongly compresso-foliaceous, arcuate, entire, the crest thin and 

 punctate-translucent, the summit regularly arcuate, not sulcate when 

 viewed from above but sinuate, anteriorly extended over and beyond 

 the head, posteriorly formed into a lengthily extended subulate acute 

 process, passing much beyond the femoral apices ; lateral lobes of pro- 

 notum posteriorly bisinuate, the posterior angles turned down some- 

 what obliquely and narrowly excised. Elytra oval ; wings fully ex- 

 plicate. Anterior and middle femora little compressed, margins below 

 somewhat lobate ; posterior femora not at all dilated, elongate, the 

 superior margins minutely denticulate, inferior margins sublobate- 

 dentate, the antegenicular and genicular lobes small ; first articles 

 of the posterior tarsi little longer than the third. 



The type is 0. ijennatum, described below. 



1. 0. penoiatum, sp. nov. (Plate XXII, fig. 3.) 



Body rather shining granulate ; face little oblique ; colour greyish- 

 rufescent, bearing an obscure triangular marking on each side of the 

 dorsum just above the apices of the elytra. Pronotum having the 

 crest strongly elevated, the forward part anterior to the articulation 

 of the hind femora regularly arcuate, behind that point gently 

 slowing backward and slightly concave toward the pronotal apex, the 

 process thin, acute and extended backward nearly to the apices of the 

 outstretched hind tibite. Elytra oblong, finely reticulate, wings 

 extended beyond the pronotal apex. Anterior and middle femora 

 little compressed, the margins minutely serrulate, the inferior 

 margins bearing two obtuse lobes ; superior margins of middle 

 femora little compressed, subundulate ; hind tibiae pale ochreous, 

 and armed with weak spines ; the first articles of the posterior tarsi
