elytron (not reaching the suture or outer margin), and the inter- 

 mediate and posterior tibiae towards the apex, nigro-piceous or 

 piceous ; closely, finely, the elytra more coarsely, punctate. Head 

 very broad, short, narrowly extended on each side behind the eyes, 

 the latter extremely large, deeply emarginate, very narrowly separ- 

 ated; antennae stout, long, joint 2 short, 3 a little longer. 4-10 

 wider, about as broad as long, 11 stout, nearly as long as 9 and 10 

 united, obliquely acuminate. Prothorax convex, much narrower 

 than the head, broader than long, sub quadrate, narrowed in front, 

 transversely depressed across the middle of the disc. Elytra wider 

 than the head, gradually narrowed from the base, with a shallow, 

 oblique, intra-humeral depression. Legs long, stout ; femora clavate, 

 the posterior pair very stout; anterior tibiae (fig. 29) sinuate within, 

 abruptly bent inwards beyond the middle, and armed with a long 

 sharp mucro at the inner apical angle ; posterior tibiae widened and 

 feebly sinuate ; basal joint of posterior tarsi curved. 

 Length 2J, breadth 1 mm. 



Hob. Amazons, between Para and Santarem (H. H. 

 Smith). 



One male, received in 1875. Very like X. chiriquensis, 

 o (figured elsewhere by myself and also by Pic), but with 

 the antennae stouter and not quite so long, all the femora 

 stout and clavate (the anterior pair more thickened than 

 usual, and the posterior pair very stout), the elytra nar- 

 rowed from the base and less elongate, the eyes extremely 

 large and subapproximate. X. (Zonantes) brasiliensis, Pic, 

 the <$ of which is known, must be an allied form, but the 

 description does not accord with the present insect. X. 

 nigricollis, Ch. (renamed atriceps by Pic), from Grenada and 

 Trinidad, has the upper surface similarly coloured, but it 

 differs in other respects. This is one of five species cap- 

 tured by Mr. H. H. Smith on the Amazons, each repre- 

 sented by a single example, two of them too imperfect 

 for description. 



66. Xylophilus obscuricolor. 



Hylophilus ( ? Zonantes) obscuricolor, Pic, Ann. Soc. Ent. 

 Fr. 1905, pp. 261, 264, 269. 



cJ. Oblong, rather convex, shining, clothed with long, fine, ad- 

 pressed, cinereous hairs ; piceous, the head black, the mouth-parts, 

 palpi, antennae, and legs (the outer half of the posterior femora 

 excepted) testaceous; closely, finely, the elytra coarsely, punctate.
