37. Tachys (s. s.) pumilus (Dej.) 
38. Tachys (s. s.) filax n. sp. 
Slender, subdepressed; testaceous, rather shining. Head 
nearly as wide as prothorax ; eyes very prominent ; antennae 
rather stout, middle joints about a half longer than wide, 
apex oU eighth joint reaching about to base of prothorax; 
mentum with two foraminiform punctures. Prothorax 
cordate, slightly less fhan a half wider than long (by mea- 
surement) ; base oblique at sides; sides sinuate before the 
obtuse (but nearly right) posterior angles, which are ac- 
curately defined. Elytra each with two inner striae 
slightly impressed and one or two others more or less indi- 
cated; strise slightly irregular but not distinctly punctate; 
apical recurved stria well marked and long, but second stria 
scarcely visible at apex; anterior dorsal puncture on third 
interval near basal third, posterior puncture within tip of 
recurved stria. Length ±1% mm. 
Holotype $ (United States National Museum) and 1 
9 paratype (Museum of Comparative Zoology no. 19503) 
from Cayamas, Sta. Clara, Cuba, E. A. Schwarz, Jan. 30 
and Feb. 13. Also 1 ( $ ?) paratype from Cuba, Poey Col- 
lection no. 27 (associated with Poey specimen of preceding 
species) (Philadelphia Academy of Sciences) . 
This is a very graceful species which approaches the 
form of the vittiger group of Tachys, but has the characters 
of Hayward's proximus group. It is distinguished from 
Tachys pumilus (Dej.), apparently its nearest ally, by 
much more prominent eyes, base of prothorax oblique at 
sides, and more slender form. 
39. Limnastis americanus n. sp. (PL 5, fig. 2.) 
Small, slender, subdepressed; rufo-testaceous, head not 
darker. Head with front micro-reticulate; eyes small to 
very small (see below), flattened, sometimes slightly convex, 
sometimes actually concave; two supraorbital setae each 
side, anterior one shorter ; antennae short, stout, outer 
joints moniliform ; mentum without tooth in emargination. 
Prothorax by measurement about a third wider than long,
