var. ANTILLARUM Suffrian. 
Differs from the var. tryphera in slightly longer elytra with sides 
more parallel and more feebly narrowing towards apex; longer antennal 
joints, the third generally longer than the first; prothorax less transverse 
and lateral tubercle usually absent ; the hind femora shghtly less strongly 
incrassate and the armature below more feeble, especially the anterior 
tooth of the male and the serrate ridge behind the posterior tooth of 
both sexes and the hind tibiae of the male are not or very feebly denticu- 
late internally. Length: 6-7 mm. 
Cuba: "Cuba" (Suffrian) (American Museum coll.); L. de Ariguanabo, 
Habana, October (S. C. Bruner and C. H. Ballou). 
The color of the Cuban specimens, which I owe to the kindness of 
Prof. Bruner, is dark castaneous with very feeble aeneous tint, head 
and prothorax more distinctly aeneous; the antennae are pale and the 
joints at apex narrowly infuscate; the underside and legs are slightly 
paler than the elytra, the femora blackish above; the lateral tubercles 
of prothorax are absent. 
Prof. Bruner informs me that the specimens were collected on 
Nymphaea flava Leit. 
var. TENUIS new variety. 
Narrower and more elongate than typical cincticornis or var. tryphera; 
antennal joints shghtly narrower and more elongate, third joint about as 
long as the first joint, the first three or four very often entirely black, 
the others reddish at base and black at apex. Prothorax narrower and 
frequently shorter; sides nearly parallel; apical angles not prominent; 
basal angles prominent; lateral tubercles obliterated; median line 
distinct but generally more or less interrupted at middle; sub-basal 
impression distinct ; surface sparsely and rather finely punctate, laterally 
finely rugose; elytra squarely truncate at apex; strial punctures fine 
or moderate; color of prothorax and elytra generally the same, rufo- 
flavous, metallic green or blue. Body below and legs dark castaneous 
or paler; underside densely clothed with short, white pubescence. Hind 
femora more slender and less strongly incrassate, armature more feeble 
and in the males the anterior tooth is sometimes absent; tibiae feebly 
asperate internally. Length: 6-8 mm. 
Type, male, and allotype, female, from Swansea, N. C. (F. Knab) in 
the National Museum collection, Washington, paratypes in collections of 
Cornell University and Brooklyn Museum.
