Broun. — New Genera and Species of Coleoptera. 409 



Antennae with slender pubescence, their oblong 2nd joint nut quite as 

 stout but about as long as the 1st; 3rd obconical, slightly longer than 

 broad; joints 4-6 bead-like, and of about the same length and breadth; 

 7th and 8th slightly larger, narrowed towards the apex; 9th and 

 10th rather larger, both narrowed apicallj; 11th largest, conical, sub- 

 acuminate. 



Unders* de shining, with suberect greyish pubescence. Head studded 

 with minute but quite definite granules, and bearing erect slender setae. 

 Presternum medially carinate. Anterior femora broadly grooved, all dis- 

 tinctly pubescent. Metasternum unimpressed. Abdomen elongate; basal 

 segment but little exposed, fringed behind; 2nd and 3rd about equal, 

 each longer than 4th or 5th ; 6th finely and distantly punctured, in the 

 middle nearly double the length of the 5th, with a slender basal margin, 

 and, at the apex, with a median semicircular carina. 



At once separable from E . heterarthrus by its 2nd antennal joint being 

 thinner than the 1st. 



Length, 1§ mm. ; breadth, quite ^ mm. 



Erua. The typical specimen was found by me in January, 1910, and 

 two or three others were picked out of leaf-mould collected two months 

 afterwards by Mr. W. J. Guinness. In two of these specimens the 9th 

 and 10th joints of the antennae are more transversal and not distinctly 

 narrowed apically — possibly a sexual disparity only. 



3207. Euplectopsis heterarthrus sp. now 



Elongate, slightly convex, nitid; castaneo-rufous ; legs and terminal 

 joint of antennae i'ulvescent, tarsi and palpi flavescent. 



Head evidently smaller than thorax, nearly straight behind the small 

 but prominent eyes, longer and more narrowed in front of them; the 

 foveae small, and situated near the eyes, its surface somewhat asperate 

 or punctate, nearly smooth behind, antennal tubercles small and distant. 

 Thorax oviform, rather longer than broad, its sides moderately rounded, 

 widest at the middle, without distinct punctation ; mesial groove narrow, 

 yet definite, and extending into the basal impression, which has a thin 

 groove connecting it with the large fovea at each side. Elytra not much 

 longer than thorax, a good deal broader behind, the shoulders curvedly 

 narrowed so that the base, which is incurved, is hardly wider than that 

 of the thorax; they are only very indistinctly punctured; the sutural 

 striae are broad; the dorsal impression also is broad, deep at the base, 

 but becoming shallow behind, and is marked off from the side of the 

 elytron and the sutural stria by raised lines. Hind-body about as long 

 as elytra, the basal two segments horizontal, 3rd slightly deflexed, the 1st 

 with a transverse impression at its base. 



Legs moderately stout, the tibiae slightly curved outwardly, the front 

 and middle tarsi rather thicker than the slender posterior pair. 



Antennae stout: 2nd joint suboviform, scarcely longer than broad, 

 rather thicker than the basal; joints 3-5 transverse, quite as broad as 

 2nd; 6-8 transverse, each becoming shorter than its predecessor ; 9th 

 lather broader than 8th, but very short; 10th distinctly enlarged, also 

 tianverse; 11th largest, conical. Maxillary palpi with broadly ovate 

 terminal articulations. 



Underside chestnut-red, rather sparingly but evenly clothed with 

 greyish imbeseence. Prosternum medially carinate.
