460 Mr. A. IMurray 07i Coleoptera from Old Calabar. 



goso et punctato, vertice laevi ; thorace lateribus fere parallelis ; 



elytris parallelis, longitudine dimidii corporis^ striato-punctatis, 



ad basin forte et lateribus leviter papilloso-rugosis, striis apice 



paulo Isevioribus. 

 Long. 6^-5f lin., lat. 1| lin. 



Small ; black, shining. Antennae and legs nigro-piceous. 

 Mandibles moderate, shorter than head, bicarinate, with oblique 

 wrinkles or subcarinse within the interior ridges. Labrum with 

 a slight rounded projection on each side and in the middle, and 

 a puncture in each. Head quadridentate in front, the two outer 

 teeth longest; two deep longitudinal fovese on each side of front, 

 exactly behind margins of labrum. The foveoe are longitudinally 

 rugose; from each a sinuate furrow runs backwards and out- 

 wards, and two or three others on each side start off from it or 

 near it about the middle, faintly at first, but becoming wider 

 and deeper as they go backwards, and stopping about the same 

 distance from the front as the back part of the eye does ; where 

 they stop there are some smaller lines or furrows, and two or 

 three iri'egularly-shaped punctures, which extend faintly across 

 the head, except at the middle, which is smooth, as is also 

 the space behind. The eyes are rather flat, and are somewhat 

 encroached on behind by the integument, but there is no swell- 

 ing behind them. Thorax rather broader than long, impunc- 

 tate ; sides nearly parallel, narrowly margined ; angles rounded ; 

 tooth or fold on the sides very small ; dorsal line distinct, 

 reaching from base to anterior marginal line, and very faintly 

 beyond it ; the anterior marginal line is deep, and shows 

 marks of punctuation, particularly on the anterior side; the 

 space in front of this line is comparatively narrow. Pre- 

 scutellar space rugose in the middle, and scutellum more finely 

 BO. Elytra of the length of the half of the body, with sides 

 parallel, punctate-striate, papilloso-rugose on the inflexed por- 

 tion of the base, and very faintly so with a series of punc- 

 tures on the space within the margin, which is strongly raised. 

 Viewed in profile, the margin takes a sudden descent from 

 the humeral tooth, for about a fourth part of the length of 

 the elytra, where it forms an angle and follows the line of the 

 elytra; the strice are fainter at the apex, the terminal portions 

 of some of them being obliterated; the third and fourth striae 

 join together about one-fourth of the length of the elytra from the 

 apex. Under side impunctate, except the posterior part of the 

 head, which is faintly punctate, and the usual row of punctures 

 on each side of the middle of the abdominal segments ; mentum 

 obliquely rugose; anterior tibi?e tridentate, with a small tooth 

 or tubercle behind them ; thighs of middle legs with a row of 

 punctures along the under side.
