133 Mr. A. Murray on Coleoptera from Old Calabar. 



similiter pubescentia vestitis, vitta senea curta nitida dorso ad 

 basin utrinque indutis, limbo testaceo reflexo translucente 

 marginatis ; elytris apice paulo oblique truncatis, angulis ex- 

 ternis spinulosis ; subtus testaceus. 

 Long. 5 lin., lat. 2^ lin. 



Somewhat rhomboidally oblong-oval, convex on the back, 

 broadest and highest about the middle. Head polished shining 

 bi'assy, with a scarcely observable minute tubercle on each side 

 close to the inner margin of the eye^; along the sides under the 

 eyes clothed with a thick, rich silky, brassy pubescence ;. labrum 

 projecting, and thickly covered with projecting long hairs. 

 Antennae dark piceous. Thorax deeply emarginate in front 

 and much bisinuate behind; much narrower in front than 

 behind; sides almost straight, and having the margin reflexed, 

 so as to form a rather broad flat ledge, which is testaceous and 

 translucent, the posterior angles of which, when looked at from 

 above, seem obliquely truncate ; above this ledge a broad band 

 of thick, silky, brassy pubescence extends up the steep sides of 

 the thorax ; the disk of the thorax, which is flattish and of the 

 same proportions as the entire thorax, shining polished brassy, 

 its surface seeming to project slightly beyond the pubescent part, 

 the separation between the two being here, as in every other part 

 of the insect, well defined ; the anterior margin has a narrow 

 edging, the posterior none ; there is a transverse depression or 

 hollow band, unmarked by punctures or impressions, running 

 across the shining disk rather behind the middle. No scutellum. 

 Elytra clothed like the thorax with a brassy pubescence, and 

 having a similar testaceous ledge running round the margin, 

 which terminates as an acute, not very prominent tooth or spine : 

 on each side of the back there is a narrow bright brassy line, 

 which appears to be raised above the surrounding pubescence ; 

 it starts from the base at a point corresponding to the exterior 

 margin of the shining disk of the thorax, and proceeds parallel 

 to the margin of the elytra for nearly but not quite half the 

 length of the elytra, at first slightly increasing in breadth, and 

 then gradually tapering to a point ; it is not much broader than 

 the marginal ledge : the apex of the elytra is obliquely truncate, 

 and there may be a sutural apical spine ; but my specimen is 

 injured at that point, and I cannot say whether there is such a 

 spine or not. Under side and legs testaceous ; the last segment 

 of the abdomen veiy conical and narrow. 



This species is interesting as being the first instance which 

 has been recorded of the genus Gyretes being found in the 

 Old World, all those previously described having come from 

 America.
