others usually near second stria. Underside as in the other 
species of the genus. Microsculpture of elytra fine, isodia- 
metric. Hind tarsi more slender than in minuta. Aedeagus 
as shown in Fig. 10. 
Holotype $ (Museum of Comparative Zoology, Type No. 
28.431) , allotype $ (coll. Straneo) , and 8 paratypes (M.C.Z. 
and coll. Straneo) all from northwestern Sierra Nevada de 
Santa Marta, Colombia, 11-12000 ft., July 21, 1928 (Darl- 
ington), taken in the paramo zone. 
Pseudabaris montanus, n. sp. 
As the species of this genus are very closely allied among 
themselves and not well characterized, I give only a short 
preliminary description of this new one. Color aeneous, a 
little greenish, elytra slightly cupreous; underside dark 
brown ; legs reddish brown ; antennae wholly ferrugineous. 
Length 6.6 mm. ; width 2.7 mm. Prothorax with sides reg- 
ularly rounded, only a little narrower at base than ante- 
riorly ; base wholly impunctate, with the inner basal impres- 
sion rather slightly impressed and the outer one very short, 
nearly evanescent; spaces between basal impressions and 
lateral margins not depressed. Elytra short and convex, 
rather strongly dilated behind shoulders, which are minute- 
ly dentate; seutellar stria rather long. Apex of aedeagus 
shown in Fig. 11. 
Holotype S (Museum of Comparative Zoology, Type No. 
28.432) and allotype $ (coll. Straneo) from Rio Frio, south 
of Santa Marta at the foot of the Sierra Nevada, Colombia, 
May 15, 1928 (Darlington) ; and 4 paratypes from north- 
western foothills of the Sierra Nevada de Santa Marta, 
Colombia, not above 3,000 ft., May 22, June 2, and June 17, 
1928 (Darlington). 
This new species differs from columbicus Chaud. by 
smaller size; prothorax narrowed toward base; and elytra 
shorter, more rounded behind shoulders.
