dark scales on the vertex ; the pronotum with two pear-shaped 

 fawn markings outlined in black, the narrow ends meeting at the 

 apex, the broad ends diverging behind ; the elytra with three deeply 

 denticulate fasciae of fawn scales outlined with black or very dark 

 brown (see figure) : the first starting at the base between striae 

 1 and 5 and running obliquely just behind the shoulder down to 

 the lateral margin ; the second forming a broad common transverse 

 band just behind the middle, its outer portion curving forwards 

 and uniting broadly with the first fascia on the lateral margin — 

 these two bands enclosing an irregular cross-like area of the grey 

 ground-colour; the third forms a common subapical dentate band, 

 which is narrowly produced along the suture and also along the 

 lateral margin to the apex ; the lower surface with whitish scaling 

 irregularly tinged w'ith buff; the legs anteriorly fawn-coloured, 

 the posterior pairs of femora becoming much paler on the apical 

 half, the entire leg being whitish on the posterior face. In some 

 forms the fawn markings become almost entirely blackish and the 

 ground-colour white; in others the ground-colour is more or less 

 invaded by fawn scaling; in others, again, the fawn is entirely 

 replaced by the grey ground-colour, the bands being merely indicated 

 by separated black flecks, which are all that remains of the black 

 borders (var. obsoletus, nov.). 



Head very broad, not constricted behind the eyes, which are 

 almost circular; the forehead with a fine median stria continuous 

 with and similar to that on the rostrum. Rostrum broader than 

 long, much narrowed from base to apex, the sides straight; the 

 dorsum with a broad deep impression in the basal half containing 

 a median stria and bounded on each side by a short ca^-ina that is 

 parallel with its fellow ; the anterior part shallowly impressed in $, 

 much more deeply so in ^J ; the setae short, scale-like and recumbent. 

 , Antennae with the scape reaching the hind margin of the eye, stout, 

 curved, hardly compressed, gradually widening fj'om base to apex 

 and with short recumbent setae; the funicle with joint 2 much 

 longer than 1, 3 not or but little shorter than 1, 4 slightly shorter 

 than 3, the rest much shorter and about as long as broad. Pro- 

 thorax much broader than long, a little narrower at the apex than 

 at the base, the sides gently rounded, broadest before the middle, 

 with a distinct apical constriction, and the apical dorsal margin 

 rounded; the dorsum with a broad deep transverse impression 

 occupying the whole of the basal fourth, the remainder shallowly 

 rugose, but the sculpture almost entirely hidden by the scaling. 

 Elytra broadly ovate, the basal lobes very prominent, the shoulders 

 roundly rectangular and followed by a slight sinuation, the apices 

 jointly rounded; the shallow striae quite regular and with small
