barely detectable), inner striae strongly impressed, outer 
shallower, all except sutural slightly abbreviated at extreme 
apex ; apical stria recurved as usual ; outer edge 3rd inter- 
val with setigerous punctures just before middle and % 
from apex. Two basal joints $ front tarsus dilated, with 
anterior apical angles somewhat produced. Length 2.25- 
2.5; width 1.0 mm. (slightly more or less). 
Haiti: holotype (M. C. Z. no. 22014) and 4 paratypes 
from Roche Croix, Massif de la Hotte, 5,000 ft., Oct. 13 ; 
3 paratypes from northeastern foothills La Hotte, Oct 10-

Resembles in color the description of marginicollis 
Schaum (now called neotropicus Csiki) of Venezuela except 
that the appendages, of noctis, are testaceous (not rufo- 
piceous), with femora not infuscate. The elytra are 
described as bistriate in marginicollis ; there are numerous 
striae in noctis. 
Tachys (Tachyura) tritax n. sp. 
Form average for subgenus, convex; piceous, not dis- 
tinctly spotted, shining, moderately iridescent; appendages 
and mouth parts testaceous. Head about % width pro- 
thorax, eyes prominent; front shining, briefly bi-impressed 
anteriorly; antennae moderate, middle joints about % 
longer than wide ; mentum not biperf orate, toothed at 
middle. Prothorax about % wider than long, sides strong- 
ly arcuate anteriorly, slightly sinuate before the obtuse 
but not blunted basal angles; latter briefly carinate; side 
margins narrow; basal transverse impression deep, punc- 
tulate, but not distinctly foveate; middle line very fine, 
anterior impression nearly obsolete. Elytra each 3-striate ; 
sutural stria entire and recurved as usual, 2nd abbreviated 
about 1/6 from base and apex, 3rd extending from anterior 
puncture (about 1/3 from base) to slightly behind 
posterior puncture (about 1/3 from apex), all 3 strise well 
impressed. Male with 2 basal joints each front tarsus 
slightly dilated, with anterior apical angles slightly pro- 
duced. Length 2. 2-2. 7 ; width 1.0-1. 1 mm.
