15S MANDIBULATA.— COLEOPTERA. 



Far from uncommon in the neiglibourhood of London. " Com- 

 mon near Bottisham." — Rev. L. Jenyns. " Kimpton." — Rev. G, 

 T. Rudd. Also in Norfolk and Suffolk. 



Sp. 51. spurcaticornis. Niger, antennarum basi apiceque, pnnctd obsolete Jron- 



tali pedibusque 7'ufo-testaceis, elytris tenue stfiatis. (Long. corp. 5 lin.) 

 Ha. spurcaticornis. Ziegler.—Steph. Catal. p. 32. No. 298. 



Rather more oblong and narrower than the preceding, with the elytra more 

 faintly striated, the hinder angles of the thorax apparently more prominent, 

 and the antennae rufo-testaceous at the base and apex : in other respects far too 

 similar to constitute a distinct species. 



With Duftschmid and Gyllenhal I coincide in opinion, being convinced that 

 this insect is a mere variety of the foregoing ; but as Ziegler and De Jean 

 consider that it is distinct, and it was likewise separated by Mr. Wilkin by 

 the MS. name of Ha. angulatus ; and as Mr. Wilkins' specimen, now in Mr. • 

 Vigors' cabinet, and mine (which agree with each other), were captured in 

 very distant parts, without the occurrence of specimens near London, where 

 Ha. binotatus abounds, I shall wait the result of further experience ere I 

 re-unite them with the latter insect. 



1 believe Mr. Vigors' specimen was found in Norfolk, and mine 

 was received from Devonshire. 



Sp. 52. ruficornis. Nigro-piceus, antennis pedibusque rujis, elytris striatis 

 pubescentibus, interstitiis creberrime pimctulatis. (Long. corp. 4^ — 7^ Un.) 



Ca. ruficornis. Fabricius. — Mart. C. pi. 36. /. 13. — Ha. ruficornis. Steph. 

 Catal. p. 32. No. 299. 



Pitchy-black : head and thorax shining, the latter a little convex, with the 

 margin somewhat rufescent : dorsal line faint ; the disc obsoletely wrinkled, 

 the margins, especially the posterior, thickly punctated, depressed at the base, 

 with a broad obsolete foveola on each side : elytra opaque, slightly convex, 

 clothed with a short griseous pubescence, with a silken gloss in certain lights, 

 faintly striated, the striae impunctate, the interstices convex, thickly punctu- 

 late, the margin with a continuous series of irregular small impressions : body 

 beneath punctulated laterally : legs generally pale rufous : antennae ferrugi- 

 nous, brightest at the base. 



Var. iS. With the body beneath pale testaceous, and the elytra pitchy-brown, 

 the suture, and sometimes the thorax rufescent. 



Var. "/. With the legs deep pitchy-black, and the antennae fuscous. 



Var. §. IMuch smaller, beneath rufo-piceus : thorax with the dorsal impressimi 

 much deeper, and also the fovea at the basal angles. Ha. griseus. Panzer. — 

 Steph. Catal. p. 32. N'o. 300. 



This species varies greatly in size and colour; and I am convinced, upon a 

 re-examination of my specimens, that the supposed species (Ha. griseus of 

 Panzer's Index) is merely a small individual, having the dorsal channel rather 

 more evident: I have therefore followed Gyllenhal in uniting it with Ha. 

 ruficornis.
