PALAMINUS. 639 
21, Palaminus vittatus. (Tab. XVI. fig. 25.) 
Angustus, elongatus, nigro-fuscus ; antennis, palpis pedibusque pallide flavis; elytris testaceo vittatis. 
Long. 5 millim. 
Hab. Nicaracva, Chontales (Janson). 
Antenne rather short and stout ; terminal joint but little longer than that preceding 
it. Head very coarsely punctate. ‘Thorax transverse, but not strongly so, evidently 
narrowed behind, closely and very coarsely punctate. Hlytra moderately long, one and 
a half times as long as the thorax, rather coarsely and closely punctate, with a pallid 
vitta near each outer margin, extending the whole length, and with the hind margin 
also pale. The two examples before me do not exhibit any conspicuous sexual 
mark. 
22. Palaminus humeralis. 
Fuscus ; antennis, palpis pedibusque pallide flavis; elytris utrinque vitta sat elongata testacea. 
Long. 43 millim. 
Hab. Muxico, Teapa (coll. Chevrolat). 
Antenne rather short and moderately stout, very pallid; terminal joint evidently 
shorter and longer than that preceding it. ‘Thorax strongly transverse, a little narrower 
than the elytra, rather closely punctate, with a faint depression on each side near the 
middle. Elytra only moderately long, rather closely punctate, with a humeral mark 
not reaching the apex; the hind margin very narrowly pale. 
One example. 
23. Palaminus diffinis. 
Parvus, angustior, elongatus, testaceus, abdomine ferrugineo ; antennis, palpis pedibusque pallide flavis ; capite 
prothoraceque obsolete punctatis. 
Long. 33 millim. 
Hab. Nicaragua, Chontales (Janson). 
This obscure little insect is very distinct on account of its more obsolete punctuation. 
It is of very slender form, and, with the exception of P. fragilis, the smallest species 
yet described. The antenne are short, with the terminal joint slightly thicker and 
longer than that preceding it. The eyesdo not quite attain the vertex. Thorax trans- 
versely subquadrate, but little narrowed behind, dull, only cbsoletely punctate, with a 
faint broad depression on each side of the middle. Elytra very slender, elongate, nearly 
twice as long as the thorax, rather closely and somewhat finely punctate. Unique. 
Subfam. HV AISTHETIN AL. 
These insects, though allied to the ‘“‘ Pederine” and “Stenine,” must receive the 
rank of subfamily, as the structure of the front coxz is totally different from that of 
the “ Peederine,”’ and the insertion of the antenne and the structure of the trophi will
