RHYNCHITES. 21 
punctate, but little shining ; vertex with a silky opacity, viridescent, obsoletely punctate ; 
eyes widely separated, convex, close to the thorax. Thorax rather broad, rounded at 
the sides, viridescent, densely, coarsely, and deeply punctured. Scutellum minute. 
Elytra with very regular series of distinct punctures, which are setigerous; the 
interstices not punctate, but with the minute pubescence serially arranged. Two 
specimens. 
13. Rhynchites oculatus, sp. n. 
AEneo-niger, supra eneus, sat nitidus, tenuissime pubescens; prothorace densius fortissime punctato, elongato ; 
elytris fortiter profundeque seriatim punctatis, interstitiis angustis subelevatis. 
Long. cum rostro 2 millim. 
Hab. GuateMata, near the city 5000 feet (Champion). 
Head and rostrum dull and opaque, silky. Head brassy, with a few rather large, 
but quite obsolete punctures ; eyes very convex, widely separated. ‘Thorax longer than 
broad, very long and narrow, the sides very slightly rounded, distinctly contracted at 
the base, extremely densely and very coarsely punctured. Elytra with quite regular 
series of deep coarse punctures, as deep at the extremity as at the base. Two 
specimens. 
14. Rhynchites guatemalenus, sp. n. 
Niger, supra subcyaneus, tenuissime pubescens, sat nitidus ; prothorace fortiter crebre sat profunde punctato, 
elongato ; elytris seriatim punctatis, punctis pone medium subobsoletis, interstitiis planis, latis. 
Long. cum rostro 2-3 millim. 
Hab. Guatemata, Chiacam, Tamahu, San Juan, San Gerdénimo (Champion). 
Rostrum dull, entirely black; head also quite dull, nearly black, being very slightly 
tinted with bluish colour, with a few very obsolete punctures between the widely 
separated eyes. ‘Thorax elongate and narrow, longer than broad, but little rounded at 
the sides, moderately closely, coarsely, and deeply punctate. Elytra with regular series 
of punctures, the punctures rather coarse at the base, subobsolete towards the apex, but 
again rather coarser and deeper on the declivous apex. | 
We have only either one or two specimens from each locality, but I believe I have 
the sexes before me; the rostrum and thorax being rather longer in one, which I 
presume is the female. | 
15. Rhynchites debilis, sp. n. 
Niger, supra sneus, nitidus, omnino parcissime pubescens; prothorace elongato, sat crebre et sat fortiter 
punctato ; elytris seriatim punctatis, punctis pone medium subobsoletis, interstitiis planis, latis. 
Long. cum rostro 23 millim. 
Hab. Mexico, Jalapa (Hoge), Teapa in Tabasco (H. H. Smith). 
This insect is very closely allied to R. guatemalenus, though the brassy colour is very
