Hab. Panama, Volcan de Chiriqui (Champion). 
Gorham based his description of P. tenwistriata upon two 
females from Chiriqui belonging to different species. The 
larger form (length 23, breadth 12? mm.), with reddish 
legs, antennae, and abdomen and clearly cut fine elytral 
striae (marked type by the author) must be taken as the 
type. The other form, from which the above description 
is taken, is smaller and subrotundate in shape, almost 
wholly black, and with the fine elytral striae only just 
traceable on the disc and the inner sulciform submarginal 
one less extended posteriorly; the ventral segments sub- 
connate, and the entire surface less densely and very 
minutely punctate.

9. Short ovate, broad, convex, very shining, black, the palpi and 
antennae ferruginous, the basal joint of the latter slightly infuscate, 
the femora and tibiae rufo-piceous, the tarsi ferruginous; very 
sparsely, finely, cinereo-pubescent. Head broad, densely, finely 
punctate; eyes moderately large, angularly compressed (when 
viewed laterally), not very deeply excised; antennae 9-jointed, the 
first two joints of the club triangular, the first very stout, the apical 
joint elongate; thorax closely, minutely punctate; elytra short, 
sparsely, finely, seriato-punctate, the two submarginal striae deep 
and confined to the apical half, the inner one not nearly reaching 
the suture, the short subhumeral stria wanting, the humeral callus 
inconspicuous. Beneath densely punctate.

Hab. Panama, Pefia Blanca (Champion). 
One specimen. A small, short, convex, very shining, 
black form, broader than P. contracta, with angularly com- 
pressed eyes, finely seriato-punctate elytra, and the two 
submarginal striae of the latter abbreviated anteriorly. 
The ventral segments are apparently free, but this character 
was unfortunately not noted when the specimen was re- 
mounted. P. brevilinea is related to P. brevis and P. 
tenwstriata, Gorh., both of which have almost complete 
submarginal striae to the elytra.
