8. Palaminus gracilipes. 
Elongatus, angustus, ferrugineus; antennis, palpis pedibusque pallide flavis ; elytris testaceis, sutura angustis- 
sime fuscescente; prothorace gracile, crebre fortiterque punctato. 
Long. 6 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet, Pefia Blanca 4000 to 5000 feet 
(Champion). 
Antenne long, very slender. Head considerably narrower than the elytra, coarsely, 
punctate, the eyes not quite attaining the hind margin. Thorax about as long as broad, 
strongly narrowed behind, coarsely not densely punctured, with a smooth space on the 
middle and a slight depression on each side of it. Elytra not quite twice as long as the 
thorax, coarsely punctate, the hind margin impunctate. Legs very slender. Terminal 
styles very long. The unique typical example has the last ventral segment quite simple 
and is probably a female; the exponent from Pefia Blanca is extremely mutilated, and 
I am not at all sure that it is really conspecific. 
9. Palaminus fusciventris. 
Gracilis, testaceo-ferrugineus, abdomine fusco-ferrugineo ; antennis, palpis pedibusque pallide flavis ; prothorace 
gracile, fortiter punctato ; elytris minus elongatis. 
Long. 43 millim. 
Hab. Nicaraaua, Chontales (Janson). 
Antenne rather slender, moderately long; terminal joint scarcely at all thicker and 
but little longer than the penultimate joint. Head short and broad, quite as broad 
as the thorax, the eyes attaining the vertex. Thorax rather broader than long, much 
narrower than the elytra and greatly narrowed behind, irregularly, moderately closely 
punctate, and impressed on each side of the middle. Elytra very coarsely punctate, 
rather convex, scarcely one and a half times the length of the thorax. 
This obscure insect much resembles P. deforms and its allies, but from the structure 
of the antenne must be placed in this group. It is unique. 
§ 2. Lerminal joint of the antenne with less slender base, and always distinctly broader 
than the preceding joint. 
10. Palaminus sordidus. 
Hlongatus, angustulus, ferrugineus; antennis, palpis pedibusque pallide flavis; elytris testaceis, sutura basin 
versus, abdomineque ante apicem fuscescentibus. 
Long. 5 millim. 
Hab, Mexico, Cordova (Hége). 
Antenne slender, the terminal joint a little stouter than that preceding it, but only 
slightly longer ; last joint of the maxillary palpus only moderately large. Head a good 
deal narrower than the elytra, the eyes not attaining the vertex. Thorax evidently 
broader than long, but a good deal narrower than the elytra, curved at the sides and
