Coleoptera of St. Vincent, Grenada, and Grenadines. 263 
Hab. St. Vincent—Windward and Leeward sides, 
Kingstown ; Grenada—Balthazar and Mirabeau Estate 
(Windward side). 
A widely distributed Tropical-American insect ranging 
from the Mexican State of Vera Cruz to Brazil. This 
species is subject, like many of its congeners, to great 
variation, almost entirely testaceous examples occurring, 
or with only a trace of darker bands on the elytra. In 
well-marked specimens the elytra are greenish-black, 
each with a curved testaceous stripe on the disc ending in 
a knob-like projection. 
Systena bicolor, sp. n. 
Flavous or fulvous, the apical joints of the antenne fuscous ; 
thorax with a narrow dark lateral stripe, impunctate ; elytra finely 
punctate-striate, dark «neous or blackish-green, with a larger or 
smaller flavous lateral spot. 
Var. a. Elytra flavous, a triangular spot surrounding the scutel- 
lum, and the apex, greenish-black. 
Var. b. Elytra entirely dark-coloured. 
Length, 1-1} line, 
Head impunctate, flavous, the extreme base sometimes piceous ; 
frontal tubercles small, transverse; palpi slender; antennz 
extending beyond the middle of the elytra in the male, shorter in 
the female, the first joint thick and straight, the second one-half 
shorter, the third and fourth joints equal, the others slightly more 
elongate, all the joints furnished with rather long hairs, the lower 
four or five flavous, the remainder nearly black; thorax rather 
convex, about one-half broader than long, the lateral margins 
rounded in front, constricted at the base, the surface impunctate, 
flavous or fulvous, the sides with a very narrow piceous stripe 
(sometimes obsolete) ; elytra with a depression below the base, 
finely and rather closely punctate-striate, the greenish-black por- 
tion of variable size—in some specimens occupying the entire disc, 
leaving only a flavous spot at the sides, in others the latter colour 
prevails—the base with a triangular blackish spot surrounding the 
scutellum, the apex entirely of that colour ; the underside and legs 
flavous, the abdomen sometimes stained with piceous ; posterior 
femora but moderately thickened, the metatarsus of the posterior 
legs as long as the following three joints united ; prosternum very 
narrow ; anterior coxal cavities closed.
