BARBADOS-ANTIGUA REPORTS 33 
with distinctly elevated margins and a very strong median carina, which, 
however, fades out before extending over much more than half the length 
of the occiput; frontal costa narrowed slightly mesially and suleate almost 
to the elypeus and very nearly to the point of mergence with the fastigium ; 
eyes about twice as long as the greatest width, narrowing apically, the 
anterior border almost straight; antenne scarcely longer than the head 
and pronotum together and noticeably flattened, especially basally, where 
several of the segments are somewhat broadened. Pronotal disk truncate 
anteriorly, obtuseangulate posteriorly and with persistent and well elevated 
median and lateral carine, the latter almost parallel and the median carina 
severed by two transverse sulci, the posterior one of which is situated be- 
hind the middle; lateral lobes slightly longer than high, the lower margin 
slightly rounded and very gently ascending anteriorly, the anterior and 
posterior margins diverging upwardly, the anterior margin decidedly more 
so than the posterior one; prosternum with a flat subquadrate plate; 
mesosternal interspace subquadrate, that of the matasternum closed pos- 
teriorly. 
Legs rather slender; posterior femora regularly but not very noticeably 
marked on the outer face by diagonal concolorous ridges meeting on the 
median line to form basally directed obtuse angles; apical angles rounded, 
the genicular angles acuteangulate; posterior tibie with from eleven to 
twelve spines on the outer superior margin, the opposite margin with eleven 
spines besides the two longer apical calcars. 
Organs of flight decidedly abbreviated; tegmina not much exceeding 
the pronotum in length and leaving a fourth or more of the abdomen ex- 
posed; the shortening of the tegmina is due apparently to a reduction of 
the apical portion, which results in the intercallary area, with its rather 
distinct intercallary vein, extending almost to the tip of the tegmen; 
humeral area only very moderately expanded and furnished with some- 
what regularly disposed subparallel transverse veins; costal area broad 
and extending the entire length of the tegmen and with irregular sub- 
parallel diagonal veins; the ulnar veins of the tegmina are stout and 
separated for about their basal third or half, beyond which point they are 
fused, the space between their separated bases forming a rather noticeable 
area; wings about one-half as long as the tegmina, but well formed and 
with distinct venation, the anal and middle areas folding fan-like when 
closed. 
Abdomen moderately slender and dorsally subcarinate; supraanal plate 
elongate-triangular, the sides straight, dorsally longitudinally shallowly 
suleate mesially between two low ridges, the lateral margins elevated slight- 
ly, especially basally, where the plate is laterally compressed to form a 
small lateral oval area; subgenital plate much elongated, somewhat narrow- 
ly pointed and extending considerably beyond the supraanal plate and 
cerci; cerci simple, but little over twice as long as broad, very slightly 
flattened and tapering to a moderately sharp point. 
General coloration wood-brown; eyes generally slightly darker than the 
general color; disk of lateral lobes, especially in the upper portions, a post-
