5 2 COLEOPTERA 



The frontal fovete resemble in their depth and direction those of the 

 Acupalpus group, but are scarcely so sharply incised. The meta- 

 sternal episterna are elongate, and their epimera normal in shape. The 

 palpi are fully as acute as in the Trechi, but their terminal joints are 

 rather broader near the base, i.e., more fusiform in figure. The tooth 

 in the centre of the emargination of the mentum is as long as the side 

 lobes, and has a pair of strong bristles at its base. 



Upon the whole, I am inclined to think that the nearest affinities of 

 this interesting form are in the direction of such genera as Lecanomerus 

 and Trachysarus. 



102. S. anomalus, Bates; Entom. Mon. Mag., January, 1878. 

 Modice convexus, politus, nigro-piceus ; partibus oris, antennis, pedi- 

 busque fulvo-testaceis ; capite parvo, oculis prominulis ; thorace capite 

 vix latiori, quadrato, ante medium paulo rotundatim dilatato, angulis 

 posticis rectis ; elytris thorace plus quam duplo latioribus, ante apicem 

 leviter sinuatis, passim aequaliter sub-punctulato-striatis, interstitio 3 io 

 pone medium unipunctato. 



Long., 2\ lin. $ $ . 



Similar in form to Anchomenus, but of small size, glossy piceous- 

 black, with the antennae, legs, and parts of the mouth tawny testaceous ; 

 in some examples the femora and palpi are paler and yellowish. The 

 thorax is but little broader than the small head, and is quadrate in 

 shape, with the sides a little rounded outwards anteriorly, and incurved 

 posteriorly, with distinct hind angles ; the surface is smooth, with a long 

 and rather deep, but wholly smooth, fovea on each side. The elytra 

 are broad in comparison with the head and thorax, very glossy, and 

 striated with equal distinctness throughout, the striae being indistinctly 

 punctated. 



Auckland, New Zealand. In my own collection and that of Dr. D. 

 Sharp. 



NOTE. The habitat cited is a mistake. I found the insect at 

 Tairua, and sent some specimens to Dr. Sharp, who informed me that 

 he had transmitted some of them to Mr. Bates ; the latter gentleman 

 wanted more, as he then thought that it was a new genus near 

 Oopterus, 



Group HARP ALID^E. 



Antenna ten-jointed, inserted at the lateral margins of the forehead 

 near the eyes. Legs slender, not adapted for swimming ; tarsi five- 

 jointed ; the three first of the two anterior pairs slightly dilated among 

 the males, and finely spongy below. Posterior coxa narrow, prolonged 

 behind in the form of a large lamella covering part of the abdomen. 

 Prosternum arched. 



Euthenarus. 



Bates; Ann. Mag. Nat. Hist., March- April, 1874. 



Gen. Tachycello similis. Palpi robusti, glabri; articulo terminali 

 fusiformi, versus apicem attenuate, apice leviter truncate. Antennce
