Amphidees longulus Sharp 1891

Hab.MEXICO, San Antonio de Arriba (Sallé), Tehuacan (Höge).

Angustulus, sat elongatus, sordide squamosus, hispidus; prothorace dense rugoso, medio tenuiter canaliculato; elytris seriatim fortiter punctatis, interstitiis minus latis.
 
Long. cumque rostro 6—7 millim.

This species is covered with a squalid squamosity, which is apparently caducous, and the surface is frequently discoloured with dirt; it is hispid with fine hairs which are not at all dense, and are either black or grey in colour. The rostrum is rather short, with no impressions; on the front of the forehead there is a minute fovea. Thorax greatly rounded at the sides, equally narrowed in front and behind, with the surface rugose, the interstices squamose; there is a channel along the middle. Scutellum very minute. Elytra oblong, with regular series of moderately large punctures, separated by rather small intervals. The male has a large oblong impression extending from the hind margin of the metasternum to near the hind margin of the second ventral segment.
 
Höge found a good series of this species, but nearly all the specimens are very dirty, and apparently the dirt and squamosity become agglutinated by some exudation.
 
The second ventral segment is rather shorter in this species than in the allies. Dr. Horn pointed it out in our collection as similar to Peritaxia rugicollis; I should not, however, from his generic table, refer it to Peritaxia at all, the first ventral suture being nearly straight, and the second segment scarcely so long as the following two together, which would bring it into the first group of genera distinguished by the table on p. 38 in the “Rhynchophora of N. America.”
 
Nocheles vestitus, Casey, is an allied but distinct species.
