A5O Dr. G. A. K. Marshall on 
punctures, each containing a flat scale or a short recumbent 
seta, and with a slightly raised smooth central line. An- 
tenn with the scape rather abruptly clavate ; the funicle- 
with joint 2 half as long again as 1, the remaining joints 
much longer than broad, each one only slightly widening to 
its apex, joint 3 rather longer than 4, 4 to 7 subequal 
and each about as long as joint 2 of the club; the club 
with joint 1 longer than 2 and about as long as 3+4. 
Prothorax broader than long, its sides regularly rounded, 
broadest about the middle, with a well-marked subapical 
constriction, the base shallowly bisinuate and its margin 
distinctly raised; the upper surface rugose, with low con- 
fluent shiny granules, the median area of the disk slightly 
flattened longitudinally, and sometimes with a trace of a 
central stria; the scales sparse, small and narrow, the sete 
very short and recumbent. Scute/lum subquadrate, clothed 
with dense scaling. lytra elongate in the g¢ and gradually 
narrowed posteriorly from the shoulders; broader in the 9 
and parallel-sided trom the shoulders to beyond the middle; 
the base truncate, the apices each with a short divergent 
point, the shoulders roundly rectangular; with 13 regular 
shallow strize, containing large quadrate punctures, the sixth 
stria extending only from the base to somewhat behind the 
middle and almost obscured by tlie scaling, tbe ninth and 
tenth arising at some distance behind the shoulder; the 
intervals all of equal height, much narrower than the strie, 
and bearing a few minute punctures ; in the two stripes the 
large rounded scales are densely packed, and among them 
are numerous broad, short, curved, scale-like sete; the rest 
of the surface is thinly clothed with minute narrow scales or 
recumbent setee, with a few larger scales in some of the 
punctures. Legs long and slender, red-brown, thinly clothed 
with very small scales. 
Length 9-103, breadth 33-4 mm. 
LESSER ANTILLES: Dominica (77. A. Ballou). 
This species is the representative in Dominica of D. hem- 
grammus, Chev. (Natural. 1880, p. 197), which oceurs in 
Martinique. The latter insect differs in the following parti- 
culars:—The rostrum is more strongly punctate and the 
central line is more raised in the anterior half; the eyes are 
rather more convex and the forehead is a little broader pro- 
portionately; the prothorax is broader, more finely and 
closely granulate, and the sides are more strongly rounded ;. 
on the elytra the discal stripe does not curve in to the suture, 
but stops at the top of the declivity, with its inner edge 
covering the third stria ; the stripe is also nearer the suture,
