160 MANDIBULATA. COLEOPTERA. 



tending to the base nor to the apex: body piceous beneath: legs rufo-ferru- 

 ginous, with all the tibiae compressed, much dilated externally, and entire. 

 Differs from the next by being of a darker hue, with four striae only on each 

 elytron — the marginal one being obliterated— and by having the tibiae dilated. 



Not very uncommon near London ; frequenting sandy or gravelly 

 situations, such as the sand-pits on Hampstead-heath, and the gravel- 

 pits at Coombe-wood, where it has been taken in plenty, especially 

 at the latter place in the spring : it also occurs in Norfolk and near 

 Bristol. 



Sp. 5. piceus. Rufo-piceus, loevissimus, elytris strid marginah quatuorque dor- 

 salibus utrinque abbreviatis impunctatis, tibiis angustis subinermibus. (Long, 

 corp. ^— f lin.)

Above deep rufo-piceous, very smooth and shining: head rounded; forehead 

 rather flat : thorax deeply emarginate anteriorly, with the sides rounded and 

 narrowly margined, the base slightly bisinuated : elytra dilated, nearly gib- 

 bous, each with five very faint impunctate striae, the marginal one longest, 

 extending from the base to beyond the middle, the dorsal ones shorter and ab- 

 breviated at both ends : body pale, rufo-piceous beneath ; with the sides finely 

 punctate, the middle smooth : legs pale reddish, with the tibiae slender, sub- 

 linear, and scarcely denticulate. 



The elongate marginal stria on the elytra, slender tibiae, and paler colour, at 

 once distinguish this insect. 



Less common than the last, frequenting similar haunts; it is 

 found within the metropolitan district, as well as near Bristol.

B. With the body much depressed and elongate, the elytra scarcely, or not at 



all, striated. 



Sp. 6. flavicomis. Ovali-oblongus, ater, nitidus, undique punctulatus, antennis 



Jlavescentibus, pedibus rufo-piceis. (Long. corp. f lin.) 

 Hi. flavicomis. Herbst. — De. flavicomis. Steph. Catal. 107. No. 1080. 



Oblong-oval, shining, black; forehead somewhat depressed, punctate: thorax 

 with the angles acute, deeply emarginate anteriorly, and thickly punctate 

 throughout : elytra slightly dilated in the middle, the surface entirely punctate, 

 with several very short obsolete rudiments of striae towards the sides : body 

 pitchy-black: legs pitchy-red; the anterior tibiae incurved, dilated and some- 

 what denticulate outwardly : antennae flavescent, with the club pale. 



Smaller, less convex, rather shorter, but scarcely narrower, than the following 

 species. 



Rare : few specimens have hitherto occurred in Britain ; it is
