1282 COLEOPTERA 



$ . Length, 2J lines ; breadth, f line. 



Mount Egmonf. Another of Mr. A. T. Urquhart's discoveries 

 near Stratford. 



Gnomodes. 



Nov. gen. 



Body almost glabrous. Head nearly vertical in front ; the labrum 

 with a straight suture, and, like the epistome, appearing membra- 

 nous. Eyes widely separated above, distinctly facetted, reniform, 

 deeply emarginate, their greatest bulk in front. Antenna implanted 

 just in front of the emargination of the eyes, reaching backwards to 

 the hind thighs, finely pubescent, filiform ; basal joint about as long 

 as the third and fourth taken together, gradually thickened ; second 

 short, fifth slightly longer than the contiguous ones. Palpi with 

 narrow, securiform, terminal joints. Thorax cylindrical, longer than 

 broad, quite unarmed, slightly narrowed between the middle and 

 front. Scutellwn curvilinearly triangular. Elytra quite oblong, 

 twice as broad as thorax, declivous behind ; apices nearly obliquely 

 truncate but rounded at the suture. Pygidium exposed. Legs 

 moderately elongate ; femora slightly clavate, almost ridged below ; 

 tibiae straight ; tarsi with brush-like soles, third joint short, lobate, 

 the basal joint of the posterior longer than the following three. 

 Front coxa contiguous, prominent, situated close to the hind margin 

 of the prosternum. Mesosternum.sh.ori, its process moderately broad. 

 Metasternum shorter than the abdomen, convex, with a broad channel 

 behind. Hind coxae a little further apart than the intermediate. 

 Basal segment of abdomen curvilinearly triangular between the 

 coxae, 2-4 nearly equal, fifth obtusely prolonged in the middle. 



The typical species bears some resemblance to the Indian and 

 Malayan genus Gnoma, but, structurally, the two forms are essen- 

 tially different ; it should be placed near Zorion, which has differ- 

 ently-shaped eyes, thinner palpi, a shorter head, &c. 



2257. G. piceus, n.s. Shining, bearing very few, slender, 

 minute, greyish hairs ; piceous, the head and thorax nearly quite 

 black, joints 5-7 of the antennae slightly testaceous. 



Head with a broad shallow median depression, minutely and 

 densely sculptured, its punctuation irregular, round on the middle, 

 but transverse behind and near the sides. Thorax not twice as long 

 as broad, base and apex nearly truncate, a little wider behind the 

 middle than it is elsewhere, narrower and more constricted near the 

 front than near the base ; its sculpture excessively fine, so that the 

 surface would appear smooth if it were not for the presence of some 

 distant transversal punctiform impressions. Scutellum smooth. 

 Elytra oblong, humeral angles obtuse ; they are irregularly punctate- 

 striate ; with costiform interstices, the two external costae uniting, 

 extending towards, but not reaching, the shoulder ; in line with the 

 hind thighs there are six distinctly-punctured striae, on the posterior 

 declivity these become confused and less distinct, and cease alto- 

 gether at the extremity ; near the base are irregular scutellar series
