Found in numbers on Castalia odorata, also on Brasenia by Mr. 
Wenzel. 
This is a very distinct variety and readily known by its narrower 
prothorax, which is often also shorter, with feeble apical angles, narrow^er 
and more elongate elytra with smaller serial punctures, more elongate 
antennal joints and more slender and longer posterior femora. In its 
form it approaches antillarMm which, however, has the prothorax similar 
to cincticornis. 
var. RUFiPENNis Lac. 
Form and coloration as in cincticornis but head and prothorax often 
more brilliantly colored and elytra occasionally with a distinct golden 
tint; some or all antennal joints occasionally almost entirely black; 
prothorax shining and more or less finely strigate-rugose ; elytra more 
uneven, apices very frequently emarginate; strial punctures generally 
larger than in the typical form. Length: 5-8 mm.
