EMATHION. 



Emathion, Guerin, Ann. Soc. Ent. Fr. 1843, p. 178 (ex parte) ; de Bonvouloir, Mon. des Eucnemides, 

 p. 637. 



As restricted by de Bonvouloir, this genus differs from Nematodes in having the fourth 

 tarsal joint simple and not excavate-emarginate. 



1. Emathion anxius. 



Emathion anxius, de Bonv. Mon. p. 640 \ 



Hab. Mexico \ Cordova (Salle). — Guiana, Cayenne l . 



Although this species differs less in the form of the clypeus than asserted by 

 de Bonvouloir, it may be known by the peculiar vestiture — a marmorate arrangement 

 in small patches of golden and brown pubescence. 



2. Emathion leprieuri. 



Galba Leprieuri, Cast, in Silberm. Rev. Ent. iii. p. 174 \ 



Nematodes (Metabletus) Leprieuri, Chevr. Ann. Soc. Ent. Er. 1867, p. 595 \ 



Emathion Leprieuri, de Bonv. Mon. p. 642 3 . 



Emathion quadraticolle, Lucas, in Cast. Exped. dans TAmer. du Sud, iii. p. 72 \ 



Hab. Mexico, Cordova 3 , Playa Vicente (Salle). — Colombia, Cartagena 3 ; Vene- 

 zuela 2 3 ; Guiana, Cayenne 1 ; Beazil 4 ; Antilles, Cuba 2 3 . 



Rather more robust than JE. anxius, and with different vestiture. 



3. Emathion intrusus. 



Similar in form to E. leprieuri, but more robust : antennse reddish-brown, the second joint distinctly longer 

 than either the fourth or fifth, these together but little longer than the sixth ; clypeus at the base a little 

 wider than the distance to the eye ; thorax longer than wide, with parallel sides, arcuately narrowed at 

 the front angles, disc slightly depressed, discal foveas very indistinct, median line rather deeply impressed 

 from a little before the base to two-thirds of the distance to the apex, from which point it becomes 

 evanescent, surface closely submuricately punctate, the intervals shining, at the sides opaque, more densely 

 punctate, the punctures forming strigse, pubescence sparse, brown, inconspicuous ; elytra vaguely striate, 

 more deeply at the apex, where the strise are coarsely punctured, intervals closely, submuricately punctate, 

 slightly shining, and with transverse strigse ; abdomen densely and more finely punctured than above, the 

 last segment much more coarsely at the tip, pubescence fine, fulvous. „ . 



Length 11 millim. 



Hab. Nicaeagua, Chontales (Belt). 



While resembling E. leprieuri in form and colour, it may be known at a glance by 

 the comparatively shining surface, owing to the less dense punctuation.
