distance iDeneath. The labial palpi are large and very evident ; the 

 antennae are nine-jointed, with a small robust three-jointed club, and 

 with the second joint large and globular ; the anterior tibiae are 

 devoid of internal spine, and the long apical process is acute and 

 strongly excurvate. The claws are long and slender, with a small 

 longitudinal carina internally at base, but not properly toothed. 

 The first four abdominal segments are connate, the sutures exces- 

 sively feeble in the middle, but not entirely obliterated, the fourth 

 suture wide and membranous. 



I think, therefore, that this interesting genus may be placed for 

 the present near Podolasia, but with the assumption that it consti- 

 tutes a connecting bond with some other group in its almost per- 

 fectl}^ free abdominal segments, extremely minute labial palpi, and 

 greatly develope^l antennal club of the male. 



In Chnaunanthus the ventral sutures are absolutely obliterated in 

 the middle, and this genus is therefore a more highly specialized 

 representative of the group Oncerini, than either Podolasia or 

 Acoma. 



A. Iiruiinea n. sp. — Form oblong, the sides nearly parallel, moderately 

 convex, dark reddish-brown throughout ; head and prothorax almost glabrous, 

 but rather densely fimbriate with long erect hairs at the sides ; elytra sparsely 

 clothed with rather long erect hairs, which are longer and more conspicuous 

 at the sides ; under surface bristling with long slender sparsely placed hairs, 

 especially (ionspicuous on the fimbriate femora. Head coarsely, very densely 

 and deeply rugoso-puuctate, the clyjjeus, which is nearly as long as the 

 remainder of the head, coarsely, deeply and sparsely punctate. Proihorax 

 four-fifths wider than long; sides strongly rounded just behind the middle, 

 thence convergent and feebly sinuate to the acute apical angles, broadly 

 rounded to the base, the basal angles being broadly rounded and obsolete ; 

 base broadly, very feebly arcuate, abruptly distinctly and more strongly so 

 opposite the scutellum ; apex broadly emarginate, bottom of emargination 

 broadly bisinuate ; disk moderately convex, polished, feebly impressed along 

 the median line excej)t near base and ajpex, finely, sparsely punctate ; punc- 

 tures entirely wanting in a broad median line, and also along the basal mar- 

 gin. Scutellum almost impunctate. Elytra widest in the middle, slightly 

 longer than wide, very slightly wider than the prothorax ; sides parallel, 

 feebly arcuate, together broadly, obtusely rounded behind ; humeri slightly 

 prominent ; disk feebly convex, strongly so at the sides, finely, feebly and 

 unevenly striate ; striae more approximate and very much confused at the 

 sides, where the surface is distinctly rugulose ; striae very finely and approxi- 

 mately punctate ; intervals each with a very uneven single line of larger, more 

 distant punctures. Length 5.0-5.5 mm.
