PALAMINUS, 635 
strongly narrowed behind, moderately closely and coarsely punctate. Elytra elongate, 
moderately closely and coarsely punctate ; along the sutural region vaguely infuscate, | 
more distinctly so about the scutellum. Terminal styles elongate. Legs moderately 
long and slender. Unique. 
The terminal joint of the antenne in this species is to a certain extent intermediate 
in form between the two groups, as it is rather more slender at the base than in the 
other species of this group, and so more disconnected from the preceding joint. 
11. Palaminus mexicanus. 
Minor, gracilis, dense punctatus, niger; antennis, palpis pedibusque pallide flavis; prothorace elongato, dense 
fere regulariter punctato; elytris dense punctatis. 
Long. 5 millim. 
Hab. Mexico (Flohr), Cordova (Hoge). 
A very distinct little Palaminus, with short and (for this genus) unusually stout 
antenne, more than usually dense punctuation, very large apical joint of the palpi, and 
short terminal styles to the hind body. The thorax is a little narrower than the elytra, 
not so long as broad, rather strongly narrowed behind, closely and almost regularly 
punctured. Llytra densely punctured, the punctures not so scanty near the hind 
margin as usual. Membranes separating the segments of the hind body pallid. Two 
examples; the one sent by Mr. Flohr, though in very bad condition, is no doubt con- 
specific with the type. 
12. Palaminus concolor. (Tab. XVI. fig. 21.) 
Latior, niger, crebrius punctatus; antennis, palpis pedibusque pallide flavis; prothorace brevi, transverso, basin 
versus angustato. 
Long. 7 millim. 
Hab. Guatemata, El Tumbador 2500 feet (Champion); Panama, Bugaba (Champion). 
Antenne short, and for this genus rather stout. Head broad and short, nearly as 
broad as the elytra, closely and coarsely punctured. Thorax much shorter than broad, 
a little narrower than the elytra, coarsely and closely punctured, with a slight longi- 
tudinal elevation or plica in the middle before the base. LElytra closely and regularly 
punctured. Legs rather short, the front tibiz stout. The male has the last ventral 
plate prolonged and strongly asymmetrical, it being narrowed towards the apex in an 
obliquely sinuous manner, the sinuosity on the right-hand side being much shorter than 
that on the left; the apex is very narrow, but not acuminate. One example from each 
locality: we figure the specimen from Bugaba; it is a female, and considerably larger 
than the Guatemalan exponent. 
13. Palaminus rubripennis, (Tab. XVI. fig. 22.) 
Niger, elytris rufis, antennis, palpis pedibusque testaceis; dense fortiterque punctatus; prothorace brevi. 
Long. 7 millim.
