330 Appendix to the Proceedings 



reaching neither to the front nor back; a depression across 

 the base, and a sinuate fovea on each side within the reflexed 

 margin, deepest and widest behind, following the outline of the 

 margin for two-thirds of the length of the thorax. Scutel- 

 lum small, triangular, finely granulose, elongate-oval, some- 

 what quadrate towards the shoulders and apex. Elytra opake, 

 flattish on the disk, convex on the sides and apex, punctate- 

 striate, the striae and punctures fine ; the interstices fiat, trans- 

 versely rugosely punctate, giving the appearance of the elytra 

 in Drypta; under a powerful lens, the rugosity of the punc- 

 tation is seen to be caused by the punctures having been made 

 as it were from behind, so that in front of each there is a slight 

 papillose elevation : besides this punctation, there is a very fine 

 transverse aciculation ; and there is a fine short pubescence pro- 

 ceeding from the punctures along the sides, which probably in 

 fresh examples will extend over the whole elytra ; the scutellar 

 stria extends nearly a fourth of the length of the elytra, and the 

 narrow edging of testaceous along the suture at the apex, w T hich 

 scarcely goes beyond the first stria, extends forwards about the 

 same length. Under side polished, shining ; prosternum very 

 sparingly and faintly punctate ; mesosternum and metasternum 

 roughly and rather closely punctate ; segments of abdomen faintly 

 rugose, particularly at the sides. 



I have only received a single specimen of this interesting spe- 

 cies, and, unfortunately, the last joints both of the palpi and 

 antennae are wanting; but there remain sufficient characters of 

 generic importance to enable me to allot it a place as a new 

 genus of the Chlceniidce. 



Oodes, Bon. 



1. 0. obesus, mihi. 



Latus, convexus, niger, subnitidus, impunctatus, laevis ; antennis 

 palpisque piceis; mandibulis piceis, planis, margine exteriore 

 reflexo ; thorace marginibus (praecipue antice) depressis, linea 

 sublaterali arcuata ; elytris punctato-striatis, interstitiis con- 

 vexis ; tarsis piceis, anticis pallidioribus. 

 Long. 5 \ lin., lat. S~ lin. 



Broad and convex ; black, smooth, and impunctate, with a 

 dull, somewhat silky lustre, occasioned by a very fine aciculated 

 punctation, scarcely visible except under the compound micro- 

 scope. Head smooth, with a slight depression along the front, and 

 with two small pits between the eyes ; middle tooth of the men- 

 turn with a tendency to become bifid ; antennae piceous, first three 

 joints shining, the rest pubescent and more dusky ; palpi piceous; 

 mandibles piceous, flat, rather thin, circular exteriorly, straight 

 interiorly, except at the point, which has a rounded tooth ;
