A NEW GENUS AND SPECIES OF SALDIDAE FROM 
SOUTH AMERICA (HEMIPTERA) 1 
By Carl J. Drake and Ludvik Hoberlandt

Through the kindness of Dr. P. J. Darlington, Museum of 
Comparative Zoology (Harvard), the writers have been 
permitted to study some undetermined semiaquatic Hemip- 
tera from widely separated areas of the world. The present 
paper contains the description of a new genus and new spe- 
cies of shore bug found on the beach of a small lake at an 
elevation of nearly 3,000 meters in the lofty Sierra Nevada 
de Santa Marta, Colombia, northern South America. The 
unit of measure is such that the formulas may be converted 
into millimeters by dividing by 80. The authors are indebt- 
ed to Mrs. R. E. Froeschner for the illustration of the type. 
Oiosalda, n. gen. 
Small, elongate-ovate, strongly convex above, remotely 
indistinctly pitted, black, shining. Head long, slender, al- 
most porrect, slightly deflected, without distinct swellings 
or callosities, even in front. Eyes moderately large, distinct- 
ly excerted, moderately convergent anteriorly, deeply 
roundly notched within just a little back of the middle, the 
hind margins slightly removed from anterior margin of 
pronotum. Ocelli tiny, not placed on a raised area or 
tubercle, very widely separated, with the width of the 
space between them about three times the diameter of 
an ocellus, the space between an ocellus and an eye sub- 
equal to or feebly greater than the distance between the 
ocelli. Pronotum shallowly roundly emarginate behind, 
the collum not distinctly set-off, also no pronotal lobes; 
i Published with a grant from the Museum of Comparative Zoology 
at Harvard College.
