20 IOWA STUDIES IN NATURAL HISTORY 
species of Anasa known and recorded from the West Indies are 
bellator Fab., andresit Guer., acutangula Stal and_ possibly 
tristis DeGeer. A. scorbutica is readily differentiated from the 
other named species by having the head armed with a long 
slender spine above each antenna and having the hind femora 
armed with two stout teeth or spines.

Apex of tylus well extended beyond apex of antenniferous tubercles; 
shorter and stouter apical segment of the antenna concolorous; 
tubercles at base of antenna sometimes obsolete; median longitud-

middle; broader species.

Four specimens from Antigua. Recorded from the following 
islands: Cuba, Isle of Pines, Jamaica, Grenada, St. Vincent, 
and Porto Rico. The collection of the American Museum of 
Natural History contains material from Haiti, Cuba, and Porto 
Rico. A closely related species, L. tipuloides DeGeer, has been 
taken by Mr. Morrison in San Domingo. JL. filiformis is smaller 
and more slender than tipuloides with the second and third 
segments of the antenna nearly equal; the veins at the apical 
margin of the corium fuscous, but the basal part of the mem-
