Psyche 
[December 
age, 8th joint about opposite base prothorax; mentum tooth 
narrowly blunted at apex. Prothorax small, subcordate 
but not strongly narrowed basally, about 1/8 wider than 
long; base truncate at middle, rounded-oblique at sides, 
about 1/5 wider than apex; sides arcuate in anterior %, 
moderately sinuate before the right, narrowly blunted basal 
angles ; margins rather narrowly explanate anteriorly, 
somewhat broader posteriorly, each with posterior seta 
present, anterior missing (as in chalybeus) ; disk some- 
what convex, middle line and anterior transverse impres- 
sion fine but distinct, posterior transverse impression 
vague; basal fovese deep but not sharply defined, very dis- 
tinctly prolonged to middle, less distinctly nearly to apex; 
surface within and near fovese and across base transversely 
wrinkled-rugulose. Elytra subquadrate, virtually twice as 
wide as prothorax (in chalybeus about 1 7/10 times width 
prothorax) ; humeri rounded but not narrowed ; sides 
faintly sinuate before independently narrowly rounded 
apices ; disk convex ; striae slightly impressed, faintly punc- 
tulate, except 2 external striae each side, and all striae at 
apex, much deeper and impunctate; intervals broad and 
slightly convex except 8th and 9th, and all at apex, narrow 
and very convex ; 3rd finely 3-punctate. Metepisterna very 
elongate ; inner wings full ; body not punctate below. Tibiae 
finely grooved along middle of outer edge; posterior tarsi 
strongly grooved each side and at middle above, grooves ap- 
proximate so joints seem bicar inate, 4th joint emarginate, 
outer lobe somewhat longer than inner; front tarsi also 
grooved both laterally and at middle (these tibial and tarsal 
characters about as in chalybeus). Length 7.6; width 
about 3.2 mm. 
Jamaica: holotype $ (M. C. Z. no. 22011), unique, from 
main range Blue Mts., about 5,000 ft., Aug. 17, 1934 ; shak- 
en from a pile of dead, cut grass in a narrow road through 
forest at Portland Gap, Blue Mt. Forest Reserve. 
Allied to C. chalybeus Dej. (Lesser Antilles to Brazil), 
of which we have specimens, but with broader elytra, with 
8th and 9th intervals differently modified. 
Agonum (s. s.) laetificum n. sp. 
Moderately broad, rather depressed ; head and prothorax
