Psyche 
[December 
broad and convex; humeri rounded; striae deep, impunc- 
tate, entire and strong at apex, 2nd as well as others entire 
at base; short accessory stria at extreme base close to su- 
ture ; 3rd stria running to humeral margin ; intervals con- 
vex, shining, 3rd with 5 setigerous punctures; trace of 
alutaceous microsculpture at extreme base of elytra. Last 
ventral with 2 setigerous punctures each side near margin. 
Front tibia with 1 strong and 1 weak tooth on outer side 
above terminal digit ; front tarsi rather widely dilated. 
Length 4.7 ; width 1.8 mm. 
Haiti: holotype (M. C. Z. no. 22012) and 1 paratype 
from Mt. Bourette, La Selle massif, 5,000 ft., Sept. 16 & 
23 ; under mossy stones in a damp gully. 
Very similar to A. Isevistriatus F. & S. of Guadeloupe 
(I have 1 specimen borrowed from the U. S. N. M.) but 
the prothorax of the Haitian species is less inflated at 
sides below the margin, and the 2nd elytral stria is not 
abbreviated basally as it is in Isevistriatus. Moreover the 
latter lacks scutellar striae and is much more alutaceous 
across the base of the elytra. The striae of the elytra are 
deeper at apex in the Haitian species. 
Tachys (Tachyta) noctis n. sp. 
Form average for Tachyta, rather parallel and subde- 
pressed, but head smaller than usual; black, appendages, 
mouth parts, and lateral margins of prothorax and (less 
distinctly) of elytra testaceous; upper surface entirely 
moderately alutaceous. Head 2/3 width prothorax; eyes 
only slightly prominent; front with usual 2 weak impres- 
sions; antennae short, 2nd and 3rd joints subequal, outer 
ones (except apical) moniliform; mentum not biperf orate, 
toothed at middle. Prothorax 2/5 or slightly less wider 
than long; sides slightly rounded anteriorly, approximately 
straight before the posterior angles (sometimes minutely, 
faintly sinuate) ; posterior angles nearly right; fine but 
distinct costa each side from base for 1/3 of length within 
(not on) margin; lateral margins translucent, evenly ex- 
planate from base to apex, as wide or wider than in 
T. flavicauda; middle line and basal transverse impression 
well marked, anterior impression very faint. Elytra only 
slightly depressed; each about 6-striate (7th and 8th strise
