meta-notum, and the short cerci recall to mind! the atrophied condition 
of the former, and the form of the latter in S''tenopeIm'atns, but the 
group of heavy spurs at the ends of the tibiae, and other characters of 
that genus, widely separate this from it. The male is unknown to me, 
but from a male of a species of this same genus, in my possession, from 
the Island of St. Thomas, it may prove to have rudimentary tegmina. 
There is no exhibition of a tympanum or auditory appai*atus upon any 
of the legs. 
ANABRUS, Hald. 
A. purpurascens. 
Brown with a tinge of purple, mottled with yellow, form similar to 
A. simplex, Hald. Face greenish or carneous-yellow, broad, somewhat 
flattened; eyes brownish-glaucous; the transverse suture below the 
front black at the exterior corners of the epistoma; tips of the man¬ 
dibles piceous-black; antennae slender, as long as the body omitting 
the head, yellow at base, and becoming lurid, and at the tip blackish; 
joints of the maxillary palpi more or less glaucous; cranium glau¬ 
cous or lurid brown, in some specimens (usually females) with the 
vertex and four longitudinal stripes carneous-yellow. Thorax rather 
short, flattened above, posteriorly, with a transverse moderately im¬ 
pressed line behind the middle, and two short oblique anteriorly diver¬ 
gent impressions before the middle; the surface smooth, lurid glau¬ 
cous, with an anteriorly dilating purplish-brown line at sides below the 
dorsal edge, the lateral margins broadly, and the anterior margin, less 
distinctly yellow; anterior angles rounded, the posterior margin trun¬ 
cated. Tegmina covered by the prothorax, yellow, with lurid purplish 
nervures; in the female the nervures are fine and longitudinal, very 
ramose; in the male the branching nervures are confined to the mar¬ 
gins, the middle field being surrounded by very stout nervures, and on 
the middle of this field is a stout nervure the ends of which run diver¬ 
gently backwards. Abdomen and surface beneath the prothorax pur¬ 
plish-brown, closely mottled w'ith yellow. Ventral surface of the fully 
colored males dull in color, the mottling being pale and not distinct 
and the pectoral surface including the coxae yellow, the last ventral 
segment deeply emarginated at tip, and furnished each side with an 
articulated cylindrical appendage; in the female the inferior surface 
is yellow with a more or less glaucous or lurid tinge. Ovipositor
