NAUTES. 285 
ferruginous; the latter long, fully reaching to the middle of the elytra in the male, joints 8-10 long and 
very slightly widening outwardly, the apical joint in both sexes a little shorter than the tenth; prothorax 
broad, transverse, convex, strongly margined, the sides a little rounded at the middle, sinuate (and a little 
widening in the female) behind, and obliquely converging anteriorly, the anterior angles broad and pro- 
minent and narrowly rounded, the apex deeply arcuate emarginate, the hind angles subacute and very 
prominent, the base very strongly bisinuate and shallowly but distinctly margined, the basal foves 
obsolete, the surface punctured like the head, only much more coarsely so; scutellum small; elytra 
rather broader than the prothorax at the base, altogether broader and almost gibbous in the female, 
strongly margined, the humeri a little prominent, deeply striate, the stric finely punctured, the scutellar 
stria obsolete, the interstices feebly convex on the disc, strongly so at the sides and apex, and very 
minutely and sparingly punctured ; legs comparatively smooth, brownish-bronze, the tarsi ferruginous, the 
latter long and rather slender; anterior tarsi with the three basal joints a little dilated, and the hind 
tibie slightly sinuous in the middle, in the male; beneath shining, brownish-bronze, with golden-green 
tints, the middle of the metasternum and the first two ventral segments with scattered coarsish 
punctures, the flanks of the prothorax and prosternum with scattered coarser impressions, the ventral 
surface also shallowly longitudinally wrinkled; prosternum horizontal, broadly produced, and received by 
the deeply excavate V-shaped mesosternum, the sides of the latter vertical in front though rounded off 
above. Body apterous. 
Length 7-8 millim.; breadth 4-43 millim. (¢ 9.) 
Hab. Guatemata, El Tumbador (Champion). 
Two examples. This insect resembles V. magnificus and N. chrysomeloides, but 
is still more vividly coloured; it will be known from either by the antenne being 
more slender, and ferruginous in colour; the thorax sinuate at the sides behind the 
middle, and distinctly margined at the base; the scutellum smaller; the elytra more 
ovate, and much narrower in the male; the legs more slender; the tarsi longer, and 
ferruginous in colour, and not nearly so strongly dilated in the male, &c. 
13. Nautes leviventris. (Tab. XII. fig. 16, 2.) 
Ovate, short, very convex, unicolorous bronze, rather dull, the elytra a little more shining. Head short, 
unimpressed, the epistoma slightly emarginate in front and not defined, very finely and very sparingly 
punctured, the vertex almost smooth ; antenns (female) rather short and slender, piceous ; prothorax short, 
transverse, strongly margined, the sides very slightly rounded and rather rapidly converging from the base, 
the anterior angles a little prominent and broadly rounded, the apex arcuate emarginate, the hind angles 
prominent, the base very strongly bisinuate and almost immarginate, the basal foves obsolete, the surface 
with indications of minute scattered obsolete punctures, almost smooth; scutellum moderately large, 
triangular ; elytra a little wider than the prothorax at the base, gibbous, rounded at the sides, the humeri 
slightly prominent, finely striate, the strie with distantly placed fine punctures, the scutellar stria 
obsolete, the interstices smooth and slightly convex; legs almost smooth, dark brownish-bronze, the 
anterior tarsi (female) with the three basal joints moderately broad; beneath shining, very dark bronze, 
impunctate, the ventral surface with shallow scattered longitudinal wrinkles, the flanks of the prothorax 
smooth ; intercoxal process triangular; metasternum short, with a rounded impression in the middle 
in front, and longitudinally impressed in the middle behind; prosternum narrow, horizontal, acuminately 
produced and received by the narrow V-shaped deeply concave mesosternum, the sides of the latter 
subvertical in front though rounded off above. Body apterous. 
Length 6 millim. ; breadth 33 millim. (¢.) 
Hab. Guatemata, Cubilguitz in Vera Paz (Champion). 
One example. This insect will be identified by its broad ovate form, gibbous elytra,
