reaching the middle of the base from each side, but not perceptible 

 across the middle ; the median line very lightly impressed. Elytra 

 elongate, oval (8 x 4| mm.), subconvex, a little flattened near the 

 base and slightly declivous to the peduncle, rather parallel on tlie 

 sides with the shoulders rounded off, broadest a little behind the 

 middle, but not noticeably narrowed to the base ; the strise near 

 the suture distinct, only the first complete, three next distinctly 

 marked on the anterior part, but becoming obsolete towards the 

 apex ; the interstices flat ; the marginal border fine. Four last 

 ventral segments with a deep round fovea on each side. 



Length 14, breadth 4| mm. 



Hah. — Hunter Iviver. 



This species seems to difler principally from P. wilcoxi and P. 

 interruptns in its narrower and more convex form. 



Promecoderus comes, n.sp. 



Of a shining bronzed black ; tarsi, palpi and antennse reddish 

 brown. Head moderate, smooth ; frontal impressions broad, 

 shallow, distinct on the clypeus, faint behind the clypeal suture, 

 this distinct between them ; transverse impression of the vertex 

 lightly marked, more distinct on each side toward the eyes ; eyes 

 prominent, inclosed behind ; post-ocular prominences small. 

 Prothorax smooth, about as broad as long (4x4 mm.), very 

 convex, declivous behind ; the sides rounded, rather dilatate, and 

 broadest at the middle, gently narrowed to the anterior angles, 

 (these not at all marked), shortly narrowed behind ; the marginal 

 border narrow, not sinuate on the sides before the base, rather 

 thicker and entire on the base ; the basal angles sharply defined 

 but hardly right angles ; median line deeply impressed. Elytra 

 oval (8x5 mm.), convex, striate, widest about the middle, a little 

 declivous to the peduncle behind the scutellum ; marginal border 

 narrow ; dorsal striae distinct, those of the sides obsolete, three 

 first strongly impressed, but only the first reaching the apex, the 

 others becoming obsolete behind, traces of three more visible 

 towards the sides ; the first interstice rather convex. Four last 

 ventral segments with a deep round fovea on each side, (in the Q 

 the foveae are often obsolete on the last segment). Male with four
