280 HETEROMERA. 
basal margin more distinct; the elytra relatively longer and more parallel, &c.; the 
ventral segments 1-3 in the male more evidently punctured and pubescent in the 
middle than in WV. fervidus. 
N. tinctus was only met with in the dense forest of the Atlantic slope,’ at elevations 
of from 3500 to 4500 feet. 
4, Nautes splendens. 
Oblong ovate, rather convex, very shining, bright metallic greenish-bronze, with cupreous or green reflections. 
Head somewhat closely and moderately finely punctured, the vertex smoother, the epistoma almost 
truncate in front and limited behind by a shallow groove, a shallow rounded impression on each side 
before the eyes; antenne moderately long, reaching to about one-third of the length of the elytra 
in the male, joints 8-10 subtriangular, equal in length, the apical one rather longer than the tenth, 
brownish piceous ; prothorax short, strongly transverse, rather convex, the lateral margins reflexed and 
prominent and narrowly grooved within, widest at the base, the sides slightly sinuate behind, very 
gradually narrowing from the base to beyond the middle, thence rapidly and obliquely converging to 
the apex, the apex deeply emarginate, the anterior angles prominent and narrowly rounded, the 
base strongly bisinuate, the basal fove deep, a distinct rounded impression on each side within the 
prominent subrectangular hind angles, and an oblique one on each side just within the anterior margin 
opposite the inner limit of the eye, the surface finely and sparingly punctured on the disc, more closely so 
at the sides (rather more finely so than the head); elytra convex, moderately long, if anything widest beyond 
the middle, very feebly rounded at the sides, very shallowly or obsoletely striate, the strie with fine but 
deep not very closely placed elongate impressions, the impressions becoming coarser towards the sides, and 
finer towards the apex, the interstices flat and exceedingly minutely and sparingly punctured, a row of 
coarse irregular impressions on each side within the lateral margin, rather variable in colour—green with 
an oblique bronze stripe from the shoulder to the apex, or, more rarely, bronze, with one or two ill-defined 
broad greenish stripes, the suture tinged with cupreous; legs blackish-bronze, the tarsi lighter; anterior 
tarsi in the male as in UN. tinctus; beneath shining, brownish-bronze, very shallowly and finely punctured, 
the metasternum almost smooth, the ventral segments 1-3 also longitudinally wrinkled, 1 and 2 with 
a flattened pubescent space along the middle in the male, the flanks of the prothorax very shallowly 
strigose externally; prosternum subhorizontal, acuminately produced; mesosternum narrow, V-shaped, 
deeply concave within, its raised sides vertical in front. Body winged. 
Length 5-10 millim.; breadth 3-53 millim. (3 @.) 
Hab. Panama, Bugaba, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
This species is perhaps nearest allied to J. tinctus, though more ovate and more 
convex, and comparatively shorter than that insect. 
Like many others of this group, WV. splendens varies greatly in size; in one or two 
of the largest female examples the usual lightly impressed elytral striz are almost 
obsolete. I met with WV. splendens in abundance about the margins of the forest on 
the slope of the Volcan de Chiriqui. A single specimen only was captured at Bugaba.
