94 MANDIBULATA. — COLEOPTERA. 



slightly striated, the striae impunctate, the interstices smooth, with two or 

 three impressed dots near the hase of the third stria, and one or two on the 

 second posteriorly; the margin with an interrupted row of impressions: 

 hody heneath shining hlack, smooth : legs testaceous. 



Found in marshy places near London and Norfolk, also on the 

 borders of Whittlesea-mere, and near Netley and Longmont, 

 Salop.

Head smooth, glossy hlack : thorax rather shorter, and the sides more rounded 

 than in the preceding insect, posteriorly less narrowed, and with a shorter 

 impressed fovea near the posterior angles: elytra simply striated, rather 

 convex, with several impressions between the second and third striae from 

 the sutm-e, and an interrupted series on the margin : body beneath black, 

 tibiae and tarsi dull ferruginous, sometimes black or dusky. 



Found occasionally near London. I have taken three specimens 

 only.

Head as in the last : mouth and palpi pitchy : antennae dusky, with the base 

 rufo-piceous : thorax obovate, narrowest behind, the base truncated and 

 without foveae ; rather convex, glossy black, or piceous, very obsoletely stri- 

 gose, and dehcately channelled : elytra oblong-ovate, rather acuminated, ahttle 

 convex, glossy pitchy-black, shghtly striated, the striae very obsoletely cre- 

 nulated ; near the third from the suture are two impressed dots before the 

 middle, and annexed to the second is a third placed posteriorly ; the margin 

 (as in several others of the genus) has an interrupted series of impressions : 

 body beneath rather smooth, pitchy-black : legs rufescent, sometimes pitchy. 



Some specimens have a very shght impression near the posterior angle of the 

 thorax, and the colour of the elytra varies, being occasionally nearly tes- 

 taceous. 

 This appears a rare species near London, but is rather common 



on the borders of Whittlesea-mere ; and the Rev. L. Jenyns has 



taken two specimens under dead bark in the winter, at Bottisham.
