West Indian Carabidse IV 
123 
Head elongate, about % wide as prothorax; eyes prominent; 
genae long and oblique; 2 supraocular setae each side; 
antennae moderate, 4th segment 4 or more times long as 
greatest width; mentum tooth acutely triangular. Pro- 
thorax subquadrate, about 1/7 wider than long at middle 
(by measurement) , very slightly narrowed at base, arcuately 
narrowed at apex ; base truncate except slightly and broadly 
emarginate in median half, apex more distinctly emarginate ; 
base about !/2 wider than apex; sides arcuate in anterior 
half, very broadly and slightly sinuate in basal half, with 
margins moderately reflexed, each with seta at basal angle 
but without anterior lateral seta; basal and apical angles 
narrowly rounded; base and apex finely margined; disk 
slightly convex, with median line well impressed at middle, 
basal and apical transverse impressions less sharply defined ; 
baso-lateral foveae moderate, extending forward supparallel 
to margins nearly to apex, finely punctate basally. Elytra 
about % wider than prothorax, slightly narrowed basally 
but with humeri about normally prominent; sides slightly 
sinuate before subindependently rounded apices; sutural 
angles subdenticulate ; striae moderate, entire, punctulate; 
discal intervals slightly convex, 3rd tripunctate, anterior 
puncture attached to 3rd stria, others to 2nd stria. Mete- 
pisterna long, inner wings full. Lower surface impunctate 
except for traces of punctures at front of mesepisterna and 
1st ventral segment. Tibiae not sulcate externally; poste- 
rior tarsi each with first 2 segments broadly and vaguely 
impressed or flattened each side, subcarinate at middle; 
front tarsi each with only basal segment thus modified ; all 
tarsi of both sexes exceptionally wide and densely pubescent 
below ; 4th segment posterior tarsus deeply emarginate, with 
outer lobe a little longer than inner; 5th segment without 
accessory setae. Male with 1, female with 2 setae each side 
apex last ventral. Length 10.5-13 ; width 3. 7-4. 4 mm. 
Jamaica: holotype ^ (M. C. Z. no. 23,014) and 7 para- 
types from Swift River town, Portland, 1,000 ft. altitude, 
March 22, 1937 ; 2 paratypes from Bath, St. Thomas, 
Jamaica, 300 ft. altitude, April 3, 1937 ; all taken by Mr. 
Chester Roys. Some at least were in epiphytic bromeliads ; 
the somewhat flattened body of the insect is probably an 
adaptation to life between the bromeliad leaf bases.
