An example from British Honduras and one from Zapote are the only specimens — 
that we have obtained. No females have been described among the Platypi costellati, 
and therefore any special characters which they may present are unknown. But 
it is probable that the following insect is the female of this species. (Tab. IV. 
fig. 24, front.) 
Fem. Flavo-testacea, elytris medio pallidioribus ; fronte supra os impressa, nitida, inter oculos punctata, pilosa ; 
prothorace oblongo, subtiliter punctato, elytris obsoletissime lineato-punctatis, interstitio 3° carinato. 
Long. 3°4 millim. 
Female. Testaceous-yellow, the elytra paler, except at the extremities. Front impressed over the mouth, with 
the margins raised along the epistoma and sides up to the antenna, its surface shining, obsoletely punctured, 
convex behind, and broadly rounded at its junction with the vertex, rather closely punctured between the 
eyes, with a fringe of erect hairs and a short median impressed line; vertex strigosely punctured, its median 
line fine, subelevated, and infuscate. Prothorax a little longer than broad, with a fine infuscate sulcus, 
delicately reticulate, with fine punctuation, denser towards the middle of the disc and a little stronger 
towards the hinder end of the sulcus. Elytra very finely punctured in rows, obsolete towards the sides ; 
interstices flat, subrugose and hairy towards the apex, base of the 3rd with numerous transverse carine , 
apical depression rounded, triangular, slightly concave, tuberculate, the inferior margin of each elytron 
subconvexly rounded, the lateral angles rounded. 
The example is from Zapote. It does not agree with the females of any other 
American group, except the Platypi terminati; and from these it is distinguishable by 
the impressed shining oral extremity of the front. The external punctures of the 
elytra are barely to be made out without a microscope. |
