NAUTES. 279 
the surface sparingly and subequally punctured, the punctures fine and shallow, and if anything a little closer 
on the disc, the sides, base, and apex lighter in colour; scutellum triangular, smooth; elytra broad, short, 
widening a little in their basal fourth, thence subparallel for about one third of their length, the humeri 
rounded and not prominent, strongly margined, striate, the striz finely, shallowly, and rather distantly 
punctured, the interstices flat and almost smooth, slightly cupreous in tint, the suture or second interstice 
and two ill-defined oblique stripes more or less metallic green; legs ferruginous; anterior tarsi with 
joints 1-3 equal in width, and dilated in the male, the fourth joint small and quite short; beneath light 
reddish-brown, shining, very sparingly and finely punctured, the ventral segments 1-3 shallowly longi- 
tudinally wrinkled, and in the male closely punctured in the middle, the flanks of the prothorax almost 
smooth; prosternum closely punctured, horizontal, subacuminately produced ; mesosternum V-shaped, 
horizontal, deeply excavate, its strongly raised sides vertical in front. Body winged. 
Length 5 millim.; breadth 3 millim. (¢ 2.) 
Hab. Muxico, Cordova (Sallé). 
Three examples. This insect is allied to WV. fervidus and the Colombian JV. ovatus, 
F. Bates *, from both of which it will be known by its smaller size and much shorter 
elytra; in general shape it more nearly resembles WV. varians and allies, though differing 
from these in its longer antennee, smoother under-surface, and other characters. 
3. Nautes tinctus. (Tab. XII. fig. 8, 2.) 
‘Oblong ovate, broad, subparallel, rather depressed, very shining, bright metallic greenish-bronze, the head in 
front, the sides of the prothorax, the scutellum, and often the extreme base of the elytra, more or less 
suffused with cupreous. Head shallowly transversely impressed in front, sparingly and moderately finely 
punctured, the epistoma broadly and shallowly emarginate in front; antenne ferruginous, the five 
outer joints rather long, almost equal in length, joints 8-10 subtriangular; prothorax very short, nearly 
twice as broad as long, rather convex, the lateral margins reflexed and prominent and narrowly grooved 
within, widest at the base, the sides slightly rounded, gradually narrowing from the base to beyond the 
middle, thence rapidly and obliquely converging to the apex, the apex rather deeply emarginate, the 
anterior angles a little prominent and broadly rounded, the base strongly bisinuate and very narrowly but 
distinctly margined, the basal fovese deep, a transverse sinuous impression before the base, and a large 
shallow irregular impression at the sides near the middle, and another within both the anterior and the 
hind angles in some specimens, the hind angles prominent but obtuse, the surface finely and sparingly 
but very distinctly punctured on the disc, much more finely and obsoletely so towards the sides; elytra 
rather long, moderately convex, subparallel to beyond the middle, shallowly depressed on each side at the 
base some distance within the slightly prominent humeri, wider than the prothorax, finely striate 
throughout, the striz with fine distantly placed impressions, the impressions finer towards the sides and 
coarsest on the basal half of the disc, the interstices broad, and perfectly flat and smooth throughout; legs 
purplish-cupreous, the tarsi lighter ; anterior tarsi in the male with the three basal joints a little dilated 
and equal in width (narrower in the female), the fourth joint small and short; beneath very shining, with 
metallic golden, cupreous, and greenish tints, the flanks of the prothorax very shallowly and sparingly 
strigose, the ventral segments 1-3 longitudinally wrinkled and very sparingly punctured, and in the male 
with a longitudinal more closely punctured pubescent space down the middle; prosternum horizontal, 
subacuminately produced; mesosternum horizontal, short, V-shaped, very deeply concave within, its 
raised sides vertical in front. Body winged. 
Length 84-12 millim.; breadth 4-5 millim. (¢ 2.) 
Hab. Guatemata, Purula and Sabo in Vera Paz (Champion). 
Six examples. This insect is closely allied to some of the varieties of WV. fervidus, 
put flatter and less convex; the basal fovez of the thorax more deeply impressed, the 
* N. elegans, F. Bates, described from an unknown locality, is, no doubt, a small individual of WV. ovatus.
