48. Palaminus flavipennis, n. sp.—Red:brown, shining, sparsely 
setose, elytra yellow-testaceous, scarcely longer than the prothorax. An- 
tenn&, palpi and legs pale yellow. Sculpture as in the other species. Pro- 
thorax strongly punctured, disc sub-carinate towards the base ; not wider 
than long, ovate, much narrowed behind, sides oblique, slightly rounded. 
Length 3.4 mm.; .13 inch. 
Tampa, MH and Capron; not rare. Agreesin color 
with £. pallipes, but differs by the smaller size, and by the 
elytra being as long as, or very little longer than the pro- 
thorax. Abdominal segments alike in both sexes. 
The species of Palaminus agree in form and seulpture, and 
the antenuz, palpi and legs in all are pale yellow. The other 
characters enable those in our fauna to be distinguished as 
follows:

* NOTE.—I have omitted P. ustus, which belongs to a different group of species 
having the color nearly uniform testaceous. P. nevadensis Austin, does not 
differ from compotens Lec. By a confusion of specimens the remarks of Mr. 
Austin concerning P. grandis Austin, are incorrect; the species is easily known 
by the large size, equal to P. femoralis, and the strongly margined, concave 
epistome.
