1424 COLEOPTERA 



2473. S. gracilis, ''-s. Slender, very elongate and narrow, 

 shining, pale chestnut-red, legs and antennae obscure-yellow, tarsi 

 and palpi yellow ; pubescence pale-yellow, mostly slender and de- 

 cumbent. 



Head quite the width of the thorax, evidently longer than it is 

 broad, widest near the obtuse basal angles, gradually narrowed 

 anteriorly ; it has two small fovese behind, and a short frontal 

 channel. Eyes very small, flat, situated at the lower part of the 

 sides. Thorax nearly twice as long as it is broad, not cordate, 

 widest near the middle (but not conspicuously so), more gradually 

 narrowed behind than in front ; on the middle, near the base, there 

 is a transversal impression, there is a small fovea at each side, and a 

 minute one near each hind angle ; between its base and the elytra 

 there is a sort of neck which is densely and minutely sculptured. 

 Elytra quadrate, and, therefore, comparatively small ; the sutural 

 striae and intrahumeral impressions entire and well marked. Hind- 

 body twice as long as the elytra, quite as broad, nearly horizontal 

 throughout, with a few erect hairs, the three basal segments 

 marginated, the third rather broad and much longer than the 

 second, which, again, is larger than the first, fourth large, obliquely 

 narrowed, the fifth narrow, retractile, and but little exposed. The 

 legs are long but not slender ; the front and middle tarsi are short 

 and thicker near the extremity than they are at the base. The 

 palpi are short and thick. 



Antenncs shorter than the head and thorax, gradually, but dis- 

 tinctly, dilated towards the extremity ; they are inserted below and 

 quite in front of the tubercles, and, consequently, more approximate 

 than in Sagola ; first joint cylindric, twice as long as the second, 

 which is rotuudate ; third small ; 3-6 more or less moniliform, each 

 slightly shorter and broader than the preceding one ; 7-8 nearly 

 equal ; ninth and tenth very short and transverse ; eleventh trans- 

 verse, broader than tenth, with a small false apical joint marked off 

 by a fringe of fine pubescence. 



Underside : Abdomen composed of six segments, the third nearly 

 twice the length of the fourth or fifth, the suture between these two 

 curved and indistinct, sixth conical, half the width of the fifth. 

 Posterior coxcb prominent, contiguous near the front.

Mount Pirongia. One, picked out of leaf-mould brought by Mr. 

 x\. T. Urquhart. This species, I have no doubt, represents a new 

 genus intermediate between Sagola and Exeirarthra. 



Exeirarthra (Gen., p. 1054, Part V.). 



2474. E. pallida, n.s. Elongate, narrow, shining, pale reddish- 

 yellow, the legs and palpi still paler ; pubescence elongate, decum- 

 bent, yellow, mostly slender. 



Head small, narrower than the thorax, the gense not contracted 

 posteriorly, with obtuse hind angles ; it has two well-marked, not 

 widely distaiit, interocular foveae, the frontal channel is short, 

 and the surface, apparently, is finely punctured ; tubercles con-
