244 COLEOPTERA. 



the interstices niX' rather iian<i\v and a little uneven, the ."^rd and fjth 

 are slightly thickened and t'levated, hut not distinctly nodifonn, near 

 the top of the declivity, wiieie tliey are bordered behind by short blackish 

 setae; the lateral sculpture is iri'egular, consisting of coaise punctures 

 and obtuse intervals. 



Scapt' insei'ted between the iiiiddk' and apex and barely leaching th« 

 eve, it is ratlifr slrnder, iiexuniis, and gradually incrassate. Funiculus 

 longer than t\\v scape, its '2nd joint hardly longer but more slender tlian 

 the basal, .'{rd and 4tli slightly longer than broad, 7th ti-ansverse and 

 rather broadei- than the preceding ones; club densely pubescent, elongate- 

 oval, its apical articulations small. 



I^nderside clothed mostly with tawny scales, but on the middle of 

 the abdominal segments 2-.") tliry are fulvescent, those on tlie sides 

 nigrescent. 



The (juite oblong form, the absence of crests and definite mai-ks, and 

 substriate elytra are distinctive. 



Length (rostrum exclusive), 4imin.; breadth, 2 mni.

Convex, subovate; the deini sliglitly nitid; piceous, rostrum 

 shining, pitchy-red, antennae and tarsi fulvescent; nearly covered with 

 variegated dejiressed squamae, chiefly light brown, and numerous long, 

 outstanding dai'k setae; across the top of the posterior declivity, slightly 

 shorter and thicker setae, usually form 4 small white tufts ; aiid there 

 are a few white setae on the front of the thorax; on the elytra a few 

 nigrescent spots can be seen. 



Rostrum about as long as the thorax, gradually exjiamU'd towards 

 the extremity; smooth along the middle, finely punctured near the sides. 

 Thoi'ax oviform, rather narrow, evidently longer than broad, a little 

 wider behind the middle than elsewhere; without inequalities of sur- 

 face, coarsely and moderately closely jjunctate. Elytra subovate, of the 

 same width as the thorax at the base, widest near the hind thighs, nearly, 

 but not abruptly, vertical behind, they are more convex than the thorax 

 and about a third longer; the disc is seriate-punctate, their hinder 

 portion striate; there is a black spot inside each shoulder, another 

 near the middle of each elytron, and a transverse series just in front, 

 and another below the white crests, these series, however, are mere specks. 



Legs long and slender, with ei'ect elongate setae; tarsi nai-row, their 

 basal and tei'uiinal joints nearly ecpial, the penultimate bilobfd and 

 moderately expanded . 



Scape shoit, gradually t^iickened, inqilanted at oi- just behind the 

 middle; funiculus more elongate, basal joint much thicker and slightly 

 longer than the 2nd, joints .3-5 slender, successively shortened, the 5th, 

 however, is not transverse. Gth and 7th broader ; clul) ovate, triarticulate. 



Underside Jiigrescent, with eoarsv greyish sotae. Hasal wntral 

 segment flat, coarsely pimctate, subtruneate between the coxae, twice the 

 length of the metasternum ; 5th reddish, nearly smooth, almost straight 

 l)ehind, the 6th short, obtusely i-ounded. 



Somewhat similar to O. Jafisnhdlus, 2967, in f(u-iu aiid vestiture, 

 but lacking the conspicuous central thoracic groove; it is further 

 differentiated by the white tufts across the top of the hind declivity, 

 and othei- detnils.
