PYRES.—RHINANDRUS. 101 
The above description has been drawn up to receive an insect discovered by the late 
Mr. Belt in Nicaragua, and an allied species from Colombia *, which we think are best 
separated from Centronopus; apart from the bright metallic upper surface, shorter 
form, strongly transverse thorax, and different facies, the antenne are more distinctly 
clubbed, the tibiz on their inner side (except at their apices) almost glabrous, the 
scutellum narrower and less transverse (though large and prominent), the elytra com- 
paratively shorter and distinctly broader than the thorax. 
1. Pyres metallicus. (Tab. V. fig. 10, ¢.) 
Centronopus metallicus, F. Bates, in litt. 
Broad ovate, subparallel, convex, bright metallic purple or cupreous, often with an neous or violet tinge, 
highly polished and shining. Head finely, closely, and shallowly punctured; prothorax strongly 
transverse, the sides rounded, feebly sinuate before the base, anterior angles prominent, though not 
acute, hind angles produced and subacute, base bisinuate and shallowly margined within (the margin not 
reflexed), lateral margins prominent and reflexed, the disc with a broad and deep transverse impression 
before the base, smooth or with fine scattered very shallow punctures; elytra broader than the thorax, 
subparallel, rather short, punctate-striate, the punctures rather distantly placed, and deeper and coarser 
(often confluent) at the sides than towards the suture or at the apex, the interstices flat and (like the 
thorax) with very fine scattered shallow punctures ; legs and beneath dark bluish-violet. 
Length 11-123 millim. (¢ 9.)

This genus has been described no less than three times by different authors. 
Rhinandrus is closely allied to Zophobas, the epistoma deeply emarginate in the male 
as in that genus, but may be known from it by the longer and more prominent 
head (the space Jefore the eyes longer and more produced); the eyes distant from the 
thorax, smaller, narrower, and more transverse (the intraocular space broader); the 
inner lobe of the maxille without a claw; the base of the elytra straighter. In 
three of the four species here recorded the base of the elytra is distinctly raised and 
* Pyres batesi. 
Allied to P. metallicus, and differing as follows :—upper surface deep bluish-green ; prothorax comparatively a 
little less transverse, anterior margin straighter ; elytra with regular rows of deep longish impressions, 
scarcely finer towards the suture, but finer and shallower towards the apex, the interstices slightly raised 
and convex. 
Length 11 millim. ( 2.)
