TARPELA. 303 
evidently sinuate before and behind; the elytra are unicolorous (without indications 
of greenish stripes or reflections), and have the punctures of the strie closer 
together, more regular, and not placed in shallow larger and longer depressions 
towards the sides, and the outer interstices are without traces of wrinkles. As in 
T. cupreo-viridis, the outer apical angles of the anterior tibie are very distinctly 
produced. 
I only met with this insect on the Guatemalan Pacific slope, and at elevations of 
from 2500 to 4500 feet. 
28. Tarpela sinuaticollis. 
Oblong ovate, convex, subparallel, bright brownish-bronze, with greenish or cupreous tints, very shining. Head 
rather closely, somewhat coarsely, and subequally punctured, the vertex smoother, the epistoma short 
and limited behind by a distinct groove; antenne rather long, in the male reaching to about one third 
of the length of the elytra, widening a little towards the apex, the joints 7-10 subtriangular, the apical 
one distinctly longer than the tenth, reddish-brown; prothorax transverse, rather convex, somewhat 
strongly margined, the margins narrowly grooved within, the sides a little rounded about the middle, 
very slightly narrowing and distinctly sinuate behind, and obliquely converging and sinuate in front, 
the apex broadly but not very deeply emarginate, the anterior angles somewhat produced and narrowly 
rounded, the base bisinuate, the basal fovese rather deep, the hind angles subrectangular or obtuse, the 
disc slightly transversely depressed before the base, the surface rather coarsely, somewhat closely, and 
subequally punctured, the base and disc sometimes rather more sparingly so, a narrow longitudinal 
space on the centre of the latter impunctate (sometimes obsolete), greenish-bronze ; elytra subparallel 
to beyond the middle, very little rounded at the shoulders, the latter rather prominent, rather long 
and convex, moderately deeply striate, the strize with fine shallow closely-placed elongate impressions 
on the disc, the impressions becoming rather coarser and deeper outwardly and finer and less distinct 
towards the apex, the interstices flat throughout and very minutely and sparingly punctured, rather 
variable in colour—usually bronzy-cupreous, with the suture and lateral margins more or less tinged 
with green, rarely bronze or green, with the suture cupreous; legs dark bronze, the tarsi lighter ; 
beneath shining, brownish-bronze, finely and very sparingly punctured (including the metasternum), 
the ventral segments 1-8 also shallowly longitudinally wrinkled, and in the male with a flattened closely 
punctured pubescent space along the middle, the flanks of the prothorax almost smooth; prosternum 
closely punctured, subhorizontal, acuminately produced, the apex with a fine raised point; mesosternum 
declivous, rather narrow, moderately deeply excavate. 
Length 5-74 millim. ; breadth 23-3} millim. (¢ 2.) 
Hab. Panama, Bugaba and David in Chiriqui (Champion). 
Eight examples. This insect resembles Vautes belti, but has the prosternum differ- 
ently shaped; the head and thorax more finely punctured; the sides of the thorax 
obliquely and sinuously converging before the middle and distinctly sinuate and a 
little narrowing behind, and the base straighter; the under surface very much more 
finely punctured, &c.; the elytra are sculptured and coloured very much as in that 
species, though rather more parallel. 
29. Tarpela puncticeps. 
Oblong ovate, moderately convex, brownish-seneous, shining. Head very coarsely, closely, and subequally punc- 
tured, the punctures here and there longitudinally confluent, the epistoma subtruncate in front and limited at 
the sides by a shallow impression and behind by a very indistinct (sometimes obsolete) groove ; antenne 
moderately long, about reaching to the middle of the elytrain the male, the apical joint longer and stouter than
