TROCHOPUS.—VELIA. 141 
This species is allied to T. plumbeus (Uhler) (= marinus, Carp.), an insect living on 
salt water in sheltered places on the shores of Grenada, St. Vincent, Jamaica, and the 
Florida Keys; but differs from it in having stouter legs, with the hind femora more 
incrassate, especially in the male, the penultimate joint of the intermediate tarsi 
shorter, the apical joint of the hind tarsi and also that of the antenne more elongate, 
the connexivum very much narrower, the body more ovate in shape, &c.

A widely distributed genus containing ten or eleven described species, two of which 
occur within our limits, whence two others are now added *. In one of the new forms 
described, V. cinctipes, the intermediate legs are very long, with their tarsi much 
longer than those of the posterior legs, as in the European V. currens (Fabr.). In 
V. brachialis and V. annulipes the intermediate legs are shorter, with their tarsi only 
a little longer than those of the posterior legs. ‘The following table will serve to 
separate the three Central-American species known to me. V. vivida was imperfectly 
diagnosed by B. White, the sex and other particulars not being mentioned. 
a. Legs rather stout and very distinctly annulate, the intermediate pair not 
very elongate; intermediate tarsi a little longer than the posterior 
tarsi; posterior femora very minutely denticulate in the ¢; sixth 
connexival segment unarmed at the tip.

Winged form, Moderately elongate, brownish-fulvous or brownish-testaccous, the posterior half of the pronotum 
fuscous; the venter and pleura more or less fuscous, and greyish-pruinose; the antenne testaceous or 
brown, with the second joint darker at the base and apex; the legs flavous, annnlated with fuscous; the 
coxa and trochanters flavous; the elytra blackish-brown, with a long silvery-white streak at the base
