convineed that there is no good reason for keeping these sep- 
arate. Occasionally the white bands on the legs and antenna 
are absent. I have not been able to distinguish Stal’s species 
mactams, described from Cuba, from some of the varieties of 
longipes. It may prove to be but another variety. 
Doldina antiguensis n. sp. 
Testaceous, with the costal area of corium lightly embrowned, veins 
pale, attenuated apical angle bright red. Veins of the membrane lightly 
infuscated. Head, seen from above, with the post-ocular part gradually 
narrowed to the basal constriction, the two sides not at all parallel to 
each other; this region about twice the length of the pre-ocular part, 
long pilose laterally. The two post-antennal spines erect, acute, about 
as long as one-half the diameter of eye; ventral surface of head very 
sparsely pilose. Antenne long, first segment reaching to apex of scut- 
ellum, very shortly and sparsely pilose. Pronotum one-fifth longer than 
wide, posteriorly armed with four rather long, erect, acute spines, those 
of the disk slightly longer than the humeral ones; the anterior lobe 
furnished with a somewhat elevated or calloused orbicular area on each 
side of a longitudinal, median shallow sulcus; transversely lightly im- 
pressed just behind the middle; lateral margins lightly embrowned; 
posterior lobe about one-third longer than the anterior lobe, closely 
punctate; provided anteriorly on either side of the middle with a short 
slightly elevated carina, evanescent before middle of the disk; between 
these provided with a distinct, rather deep, broad, median sulcus ex- 
tended to line of discal spines; extending anteriorly just within the 
humeral spines on either side is another shallow sulcus fading out about 
the middle with a short slightly elevated carina, evanescent before middle 
of the disk; between this and the carina is a short, almost obsolete 
sulcus more evident anteriorly; the lateral margins provided with a 
faint carina. The posterior margin of the pronotum straight in the 
middle, produced on either side of the base of the scutellum into a short, 
scooped out, obtuse lobe. Clavus apically and inner area of the corium 
membranaceous, translucent; between the elevated pale veins opaque and 
somewhat roughly punctate, slightly embrowned. Membrane reaching only 
a trifle beyond apex of the abdomen. Beneath shining testaceous, pilose; 
first three abdominal segments armed at the posterior apical angles with 
conspicuous spines. Length, male, 17 mm., width 244 mm. 
Type, a single male from Antigua, July 15, 1918, collected, by Profes- 
sor Dayton Stoner. Owing to the kindness of Professor Stoner the type 
is deposited in the collection of the American Museum of Natural His- 
tory. 
This species is apparently closely related to D. carinulatus 
Stal, the female of which was described from Brazil. Stal’s 
description is so meager that it is impossible without an ex-
