Staphylbddce of the Amazon Valley. 393 



Amazons ; a single individual witliout special locality. 



I have named this species in honour of INI. Albert 

 Fauvel, of Caen, whose labours on the Staphi/linidcB are 

 Avell knoAvn to all interested in this family of Coleoptera. 



Bledius, 



The species of this well-known genus here described 

 are seven in number, and suggest no special remark; only 

 one species was found by Mr. Bates, the other six being 

 discovered by Dr. Trail. Only three or four species have 

 been previously described from South America, yet it is 

 very probable that the genus is numerously represented 

 there, for these insects are very retiring in their habits 

 and little likely to come under the notice of collectors, 

 except special search be made for them. 



1. Bledius alhidns, n. sp. Pallide testaceus, obsolete 

 punctatus, subnitidus ; capite castaneo, bituberculato. 

 Long. Corp. lij lin. 



Antennre very pale yellow, slender ; basal joint as long 

 as the three or four following ones together ; 2nd more 

 than twice as long as 3rd ; the four or five apical joints 

 stouter than the others, each of them about as long as 

 broad. Mandibles elongate, their upper edge with a tooth 

 near the base, and beyond the middle wdth a long spine- 

 like tooth directed forwards and upwards. Head darker 

 than the rest of the insect, castaneous, with the eyes black ; 

 the clypeus much deflexed ; close to the eye on each side 

 is a prominent tubercle ; the punctuation is quite obsolete. 

 Thorax a little nan-ower than the elytra, not so long as 

 broad, nearly straight at the sides, with the hind corners 

 oblique ; it is almost white, exce])t that the fine depressed 

 basal margin is black in the middle ; it is extremely finely 

 channelled, and finely and obsoletely punctured. Elytra 

 short, but a little longer than the thorax, pale yellow, finely 

 and indistinctly punctured. Hind body pale yellow, im- 

 punctate. Legs very pale yellow ; the front tibiae very 

 broad below the middle, abruptly contracted at the apex. 



Jurua ; a series of individuals, captured by Dr. Trail on 

 the 3rd November, 1874. 



Ohs. — This very distinct little species can be readily 

 identified by the perpendicular front part of the head. I 

 do not observe any indications of sexual diflJerences.
