from the West Indies, 635 
much less transverse, less shining, and obsoletely punctate 
thorax, which is, however, very finely coriaceous. 
Head smaller than the thorax, greasy-lustrous, impunctate, 
finely and closely coriaceous. Antenne with the third joint 
shorter than the second, the fourth to the tenth transverse, 
gradually increasing in width, the penultimate twice as broad 
as long. Thorax one-third as broad again as long, the sides, 
gently rounded in front, almost straight and more contracted 
behind to the rounded posterior angles, the disc rather 
broadly impressed ; very finely, obsoletely, and rather closely 
punctured and finely and distinctly coriaceous, finely pubes- 
cent. Elytra a little longer and broader than the thorax, 
slightly transverse, the puncturation very similar to that of 
the thorax, but the ground-sculpture not so distinct; the 
surface therefore rather more shining. Abdomen very finely 
and sparingly punctured and pubescent, especially behind. 
A single specimen. 
St. Vincent (H. H. Smith). Type in the British Museum. 
76. Placusa insularis, sp. n. 
(Fauvel, in litt.) 
Narrow, elongate, black or pitchy, slightly shining; 
elytra brownish-testaceous, the abdomen more or less lighter 
at base and apex. Thorax distinctly more narrowed in front 
than behind; the first three joints of the antenne and legs 
testaceous. 
Length 2 mm. 
Somewhat similar in build to P. tachyporoides, Walk., but 
much smaller and narrower and the antenne stouter, 
Head finely and pretty closely punctured. Antenne with 
the third joint a little shorter than the second, the fourth 
smaller, as long as broad, the fifth to the tenth transverse, 
gradually increasing in width, the penultimate two and a half 
times as broad as long, the eleventh stout, as long as the two 
preceding together. Thorax scarcely half as broad again as 
long, as wide at the base (which is broadly but only slightly 
sinuate on either side) as the elytra at the shoulders, the 
posterior angles rounded, the sides gradually rounded and 
contracted in front ; puncturation very fine and rather close, 
finely pubescent. Elytra as long as, anda little broader 
than, the thorax, transversely, finely, aud pretty closely punc- 
tured and pubescent. Abdomen gradually pointed, very 
finely and closely punctured on the first three segments, 
more sparingly posteriorly. 
Sexual differences unknown.
