distance beneath. 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 fo% 

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

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

 fectly free abdominal segments, extremely minute labial palpi, and 

 greatly developed 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. Iiriinnea 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 (jonspicuous on the fimbriate femora. Head coarsely, very densely 

 and deeply rugoso-punctate, the clypeus, which is nearly, as long as the 

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

 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 except near base and apex, finely, sparsely punctate ; puuc- 

 tUlres '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 ; strise 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.
