Psyche 
[December 
Related to Colpodes punctus Dari, and bruesi Dari, both 
of Jamaica, but differs from punctus in metallic color and 
much less punctate lower surface, and from bruesi in punc- 
tulate elytral striae as well as in other details. 
Colpodes roysi n. sp. 
Moderately elongate, less flattened than bromeliarum; 
moderately shining dark blue, lower surface and appendages 
piceous except sides of antennal segments 4-11 brown. Head 
about % wide as prothorax, somewhat shorter than in 
bromeliarum, but similar in details of structure. Prothorax 
about 1/7 wider than long, strongly narrowed anteriorly, 
scarcely so basally; base nearly truncate, apex broadly 
emarginate ; base about 3/5 wider than apex ; sides broadly 
rounded in anterior %, faintly sinuate before approximately 
right, scarcely blunted posterior angles ; margins moderately 
reflexed, each with seta at basal angle, without anterior 
lateral seta; base and apex finely margined; disk slightly 
more convex than bromeliarum but with similar impressions, 
baso-lateral foveae similarly finely punctate. Elytra about 
% wider than prothorax, slightly stouter and more convex 
than in average bromeliarum but similar in details of struc- 
ture except apices each with a short spine opposite end of 
3rd interval, and striae not distinctly punctulate. Mete- 
pisterna elongate, inner wings full. Lower surface without 
distinct punctation. Tibiae not sulcate on outer edge ; poste- 
rior tarsi each with first 3 segments sulcate each side above 
and also vaguely sulcate at middle, so rather indefinitely 
bicarinate; front tarsi with basal segment vaguely sulcate 
each side and at middle ; 4th segment posterior tarsi deeply 
emarginate, outer lobe somewhat longer than inner. Length 
11 ; width 4 mm. 
Jamaica: holotype (M. C. Z. no. 23,015), unique, from 
Bath, St. Thomas, Jamaica, 300 ft. altitude, April 3, 1937 ; 
from bromeliads, collected by Mr. Chester Roys. 
Related to the preceding ( bromeliarum ) and more dis- 
tantly to punctus and bruesi, but at once distinguishable by 
the spinose elytra, and differing in other less obvious details. 
The difference in tarsal sulci between this species and 
bromeliarum is surprising.
