Mr. A. Murray on Coleoptera from Old Calabar. 341 



greenish colour of the head advances in the centre as far for- 

 ward as the front of the eyes, but the testaceous colour passes 

 backward on each side as far as the middle of the eye ; the apex 

 of the mandibles and of the joints of the palpi is darker than 

 the rest; clypeus rather broad; labrum quadrate, somewhat 

 broadest in front, with a large shallow depression in the centre 

 (but I am doubtful whether this is not owing to an accidental 

 crushing in my specimen) ; antenna? dark fuscous, the basal 

 joint, and possibly the second, which is the shortest, more or less 

 testaceous; eyes moderately prominent. Thorax subcordate, 

 not without resemblance to the thorax in Ayonum, coarsely and 

 granulosely punctate, so as to appear opake; margins rather 

 broadly reflexed, especially behind, with their edges narrowly 

 semitranslucent and testaceous; dorsal line well marked, but 

 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 flat, 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, which 

 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.
