Rybaxis crassipks, n.sp. 



(J. Of a rather bright reddish-castaneous, elytra and legs some- 

 what paler, tenth joint of antennae somewhat infuscated and 

 •conspicuously darker than eleventh. With short, pale pubescence. 



HpMd with two round, closed, interocular fovese of moderate 

 size; with a rather large interantenual impression. Antennae with 

 first joint fairly stout and widest near apex, fifth distinctly longer 

 than fourth or sixth; sixth, seventh and eighth produced on one 

 side, ninth and tenth trapeziform, tenth distinctly larger than 

 ninth, eleventh truncate-ovate, very little longer than tenth. 

 Frothorax about as long as wide, sides strongly rounded and 

 widest at about one-third from apex; each side near base with a 

 large fovea, the two connected by a deep impression across 

 •middle. Elytra comparatively narrow at base; each somewhat 

 membranous and obtusely produced at middle of apex; dorsal 

 striae deep at base and distinct to near apex, with small but 

 numerous punctures; epipleural furrow deep, almost straight and 

 extending to one-fifth from base and apex. Upper surface of 

 abdomen with a transverse medio-basal node, and without striae 

 or carinae at sides of same; lower surface flattened in middle. 

 Metasternujn with a small tubercle close behind each of the hind 

 coxae. Middle trochanters strongly but obtusely dentate, front 

 still more obtusely dentate; four front femora very stout; front 

 tibiae rather strongly curved, very feebly dentate at about basal 

 third; middle tibiae rather stout and obtusely produced at apex. 

 Length 2^ mm.

The four front femora are unusually stout, and in many respects 

 it agrees with Rafifray's description of E.Jlavipes (from New South 

 Wales), but ninth joint of antennae not three times as long as 

 •eighth, the apical joint pale, and abdomen without carinae. In 

 Raflfray's description he says: "Carinulis abdomiiialibus brevibus, 

 divergentibus, et parum distantibus," but Schaufuss says : " Ab- 

 dominis . . . primo prope suturam oblique bistriolato." 



From some directions the sixth, seventh and eighth joints 

 .appear to be produced on one side, and the produced points then
