22 Mr. F. P. Pascoe's Descriptions of New Genera 



appears to me, liowever, that these {R. notabilis, molorcho'ides, iri- 

 lineatus, &c.) form a distinct group,' essentially distinguished from 

 both Rhinotragus and Oregostoma by their slender form, large 

 eyes nearly or quite meeting below, antennae, and greater length 

 of the first joint of the posterior tarsi. For this group I propose 

 the name of Agaone, and Oxylymvia will differ from it in its more 

 robust form, eyes, antennae, elytra and legs. 



Oxylymvia lepida, (PI. II. fig. 3.) 



O. flava, occipite, oculis, antennis basi, humeris, fasciisque 



duabus elytrorum, atris. 

 Para. 



Sulphur-yellow, eyes, top of the head, except a yellow spot 

 between the eyes, band above the lip, and tips of the mandibles, 

 black ; prothorax smooth and polished, of a rather darker yellow ; 

 elytra thickly punctured, the shoulders, a band at the middle, and 

 the apices, black ; antennae with the first joint, ring round the 

 second, line along the third, fourth and fifth, and apices of the 

 three last, black ; legs with a line along the tibiae, and extremity 

 of the last tarsal joint and claws, black ; beneath pale yellow, a 

 broad band on the mesosternum, and two last abdominal segments, 

 black. 



Length 5| lines. 



It will, perhaps, be as well to observe, that throughout these 

 papers all Mr. Bates's important acquisitions are marked Para — 

 the province, not the city, my earlier sets of this gentleman's 

 collections having been unfortunately put away without noting the 

 precise localities from which they were derived, but I hope even- 

 tually to supply the omission. 



Thkanius. 



Head short ; labrum very small ; mandibles stout; eyes lateral, 

 large round, scarcely emarginate ; palpi rather short, the terminal 

 joint ovate, somewhat inflated; antennae short, filiform, the joints 

 cylindric, the third longest ; prothorax equal at the sides, gibbous 

 above ; elytra narrow, flat, scarcely covering the abdomen ; legs 

 short, slender ; femora not clavate ; tarsi with the first joint 

 longest. 



A genus allied to Slenopterus, but diflfering in the round eye, 

 filiform antennae, palpi, &c. &c.
