 vix dehiscentia vix truncata : pedes nigri. 

 Corp. long. 1-35 unc; elytrorum lat. max. 5 uuc. 

 /'em.— Head, including the eyes, black ; the face clothed with fer- 

 ruginous down ; epicranium impressed with a longitudinal sulcus, 

 which is very deep between the eyes ; the eyes are moderately large 

 and reuiform, the lower or cheek lobe being the largest ; the face has 

 a large and deep depression occupying the basal or upper portion of 

 the clypeus ; the first and second joints of the antennae alone are 

 present: prothorax black, clothed with ferruginous down, without 

 any trace of that central black velvety vitta which obtains in the 

 females of other described species ; the anterior portion of the pro- 

 thorax is smooth and somewhat ring-like ; the rest of the dorsal sur- 

 face uneven and tuberculated on each side ; it has two obtuse tu- 

 bercles : prosternum produced between the procoxse into two short 

 incurved, backward-directed processes which approximate at their 

 apices, leaving an aperture through which the point of a needle may 

 be passed : scutellum semicircular, clothed with ferruginous, with 

 the exception of the margin, which is glabrous : elytra ferruginous 

 and clothed with ferruginous down, wide at the base, narrowing to 

 the apex and then truncate, the angles of the truncature behig ob- 

 tuse ; the elytra are carinated, each having five carinse ; the first is 

 very short and nearly obtuse ; it commences near the scutellum and 

 ceases before it has reached a third of the length of the elytron ; the 

 second and third commence near the base of the wing and unite in 

 the apical area; the third and fourth commence almost together just 

 below the humeral angle, and unite in the apical area ; the two pairs 

 are also united, and below their union several other raised anasto- 

 mosing lines form a kind of network : the abdomen and legs are black, 

 with a short hairy pubescence ; metatibise with two distinct apical 

 spines.

 Ince, R.N., in that gentleman's cabinet.

 Notice of a Binocular Microscope. By J. L. Riddell. 

 I DEVISED last year, and have lately constructed and used, a com- 

 bination of glass prisms, to render both eyes simultaneously service- 

 able in microscopic observation. 



Behind the objective, and as near thereto as practicable, the light 

 is equally divided and bent at right angles, and made to travel in 

 opposite directions, by means of two rectangular prisms, which are 

 in contact by their edges somewhat ground away. The reflected 

 rays are received at a proper distance for binocular vision, upon two 

 other rectangular prisms, and again bent at right angles ; being thus 

 either completely inverted, for an inverted microscope ; or restored 

 to their first direction, for the direct microscope. These outer prisms
