92 MANDIBULATA. — COLEOPTERA. 



Ca. piceus. Linni.—Ag. piceum. Stepli. Catal. No. 139. 



Body black : antennae shorter than the body, black : thorax narrow, somewhat 

 rounded behind, with a central dorsal channel : elytra convex, shining, some- 

 what striated, pitchy-brown, palest at the margins : much broader than the 

 thorax: legs pitchy-red. 



The above description, kindly furnished me by the Rev. W. 

 Kirby, from the original Linnean specimen, well characterizes an 

 insect that is far from uncommon in the vicinity of London. It 

 also occurs in Shropshire and Norfolk. 



Sp. 19. Simpsoni. Nigrum, elytris fusco-piceis , subconvexis, tenus sfriatis, 



pedibus piceis, thorace breviore, latioi^e. (Long. corp. 3^ lin.) 

 Ag. Simpsoni? Spence MSS. Steph. Catal. No. 140. 



Allied to the last, but rather larger ; the thorax broader and shorter : head and 

 thorax smooth glossy black, the last obsoletely strigose, with a deep arcuated 

 and obsoletely punctate impression near the basal angles : the elytra deep 

 pitchy-brown, or black, slightly convex, a little glossy, with simple striae, 

 the margin with an interrupted series of impressed dots : the body beneath 

 black : legs pitchy. 



Taken in Battersea-fields, at Netley, Salop ; and common at 

 Bottisham, hybernating beneath the bark and roots of trees, 



Sp. 20. pullum. Nigro-piceum, elytris subconvexis nigro-castaneis, striatis, 



thorace obsolete canaliculato, pedibus piceis. (Long. corp. 3 lin.) 

 Ag. pullum. Hoffmann. BISS.— Steph. Catal. No. 141. 



Rather less than the last, which it greatly resembles : it differs in being more 

 slender and glossy : the head and thorax are smooth, the latter with the disc 

 convex, with a shallow impunctate arcuate impression at the base on each 

 side : elytra ovate, rather moderately convex, of a chesnut-black, striated, the 

 striae impunctate, with three or four rather obsolete impressions on the third 

 from the suture, and an interrupted marginal series : body beneath smooth 

 glossy black : legs rufo-piceous, with the base of the thighs, the tibie, and 

 tarsi palest : antennae and palpi black. 



Found in Devonshire, near Netley, Salop, and near London. 



Sp. 21. striatum. Piceum, subtus dilutiore, thorace subrugoso, nigro, murginibus 

 piceis, elytris castaneis prqfunde striatis, striis obsoletissime punctulatis, pedihvs 

 testaceis. (Long. corp. 3 lin.) 



Ag. striatum mihi. — Steph. Catal. No. 142. 



Also allied to the three or four preceding species, but distinguished by its 

 rugose thorax and deeply striated elytra : the head and thorax are pitchy- 

 black, the latter ruggedly-strigose throughout, with an arcuate impression on 

 each side at the base, and the margin piceous : elytra pale chesnut, rather 

 depressed, with very deep obsoletely punctulated strife, and an obscure series
