end nearly equal (42:45) ; humeral angles not produced or 
prominent; distinctly convex along its entire length, mar- 
gins extremely narrow, carina-like, of uniform width from 
base to apex, very finely pitted. Scutellum almost flat, feeb- 
ly transversely impressed at middle, a little wider at base

curved downwards on sides so as to envelope abdomen, in- 
distinctly pitted, black, very shining, the outer margins 
narrowly turned outwards and there slightly embrowned;

Type (male) and allotype (female), south side of the Si- 
erra Nevada de Santa Marta, on shore of a small lake, 1941, 
Colombia, northern South America, collected by Dr. T. D. 
Cabot, in the Museum of Comparative Zoology (Harvard). 
Paratype, 1 male, in collection of C. J, Drake. Named in 
honor of the collector, Dr. Cabot. 
This peculiar and striking little shore bug is so different 
from other species that it was necessary to erect a new 
genus for its reception; it is thus not readily confused with 
other described species.
