Rhynchites thesaurus Sharp 1889

Hab.MEXICO, Teapa in Tabasco (H. H. Smith).

Auratus, nitidus, tenuissime pubescens; rostro, antennis, pedibus, pectore abdomineque nigro-subæneis; prothorace elongato, crebrius fortiter profundeque punctato; elytris seriatim fortiter punctatis, interstitiis latis, haud omnino planis.
 
Long. cum rostro vix 2½ millim.

This insect is very closely allied to R. debilis, but it does not agree in colour or punctuation with it or with any other species of the group; and, besides this, it has the vertex less sparingly and obsoletely punctate. The punctuation of the elytra on the disc is not obsolete. The only two examples received have a short rostrum; yet I fancy they are of opposite sexes, as there are some slight differences in the form and punctuation of the thorax, as well as a small distinction in the length of the front part of the rostrum.
