196 COLEOPTERA 



small, furnished internally and apically with bent hairs ; the external of 

 the same length, ciliated inwardly and at the end truncated. Last joint 

 of the labial /^7/^/ elongate, somewhat ovate, and acuminate ; that of the 

 maxillary thickened and obtuse. Mandibles bifid at apex. Labrum 

 transversal. Head sub-quadrate ; the epistome slightly hollowed. An- 

 tennal furrows rather indistinct, short, and oblique. Antenna, robust, 

 their first and second joints thicker and longer than the following ones : 

 third to sixth obconical, decreasing; seventh to ninth sub-globular; tenth 

 and eleventh forming a small club. Eyes rounded, large, and rather 

 prominent. Pivthorax rather convex on the disc, emarginate in front, 

 narrowed behind, the sides in front dilated and finely indented. Scutel- 

 luni punctiform. Elytra short, oval. Legs short ; femora a little incras- 

 -sated ; tibice cylindrical, without terminal spurs ; the three basal joints 

 of the tarsi short, equal, pubescent below. Prostermini projecting. 

 Body oblong, furnished with hairs above.

Long. Corp., 2| mm. 



Antennce short, red, eleven-jointed, the basal joint scarcely visible 

 from above ; second a good deal larger than the following ones ; third 

 small, but distinctly longer than the following joints; the fourth to eighth 

 being small, ninth small but transverse, tenth broad and transverse, 

 eleventh short and not quite so broad as the tenth. Eyes bearing a few 

 short coarse setse. Thorax about as long as broad, nearly as broad as the 

 elytra, only slightly narrowed behind, and the sides very little curved 

 towards the front angles ; the surface a little uneven, bearing short 

 coarse set* or scale-like hairs ; the lateral margins densely fringed with 

 such setse. Elytra apparently rather coarsely and closely sculptured, but 

 their sculpture rendered indistinct by the dense short setse with which 

 they are clothed ; these setae are a little variegated in colour ; there are 

 no tubercles or depressions. Head with rather long cavities beneath, 

 directed backwards, so as to be parallel along the inner margin of the 

 eyes ; sides of the thorax near the front angles slightly depressed, so as 

 to indicate the rudiments of cavities for the protection of the antennae. 

 Legs red ; tibite armed externally with fine short setae. 



Obs. — This species departs somewhat from the European Coxelus 

 pictus, by the more elongate antennal cavities and by the slightly concave 

 front part of the surface of the undersides of the thorax ; but its general 

 structure seems to be so similar to that of the European species, that I 

 think it would be premature to characterize it at present as a distinct 

 genus.
