Apion {Trichapion) auronitidum Wagner 



Apion {Trichapion) auronitidum Wagner, Arch. Naturg. Berlin, vol. 78, p. 113, 

 1912. 



Description: This species was described from a single female 

 from Capetillo, Guatemala, in the British Museum (Natural History) 

 that was not seen by the author. The following notes are a transla- 

 tion of the original description. 



Length, 1.8 mm. 



Closely related to A. suhrujum Sharp, somewhat smaller and more 

 compact in form, can be recognized by the following characters: 

 beak of female somewhat shorter, at antennal insertion somewhat 

 more widened and a little more strongly curved. The head is a 

 little wider, the frons with a wide, shallow middle striae and finely, 

 sparsely punctured; the prothorax is of the same general form, but 

 the disc is nearly impunctate, the sides with large, shallow, distant 

 punctures; in front of the scutellum is an indistmct, shallow impres- 

 sion. The elytra in comparison with the prothorax is distinctly shorter 

 than in subrufum, widest pomt nearly at middle, with strong humeri; 

 striae with finer, shallower punctures, intervals slightly convex, with 

 fine hair-bearing punctures. Legs same as suhrujum, only the 

 tibia blackish, while in suhrujum the tibia are rusty red. With 

 yellowish pubescence especially on head and prothorax, where it is 

 distinctly longer and somewhat denser than suhrujum. Head, 

 prothorax, and elytra with a bright metallic gold luster. De- 

 scribed from a specimen in Sharp's type series of suhrujum, from 

 which it differed by the rust red color of the elytra and prothorax with 

 its slight metallic luster.

Figure l,e,j,k 



Description: Length, 3.90 mm.; width, 1.75 mm. 



Moderately robust, depressed. Black; pubescence conspicuous, 

 white, long, fine, somewhat coarser and denser on sides of mesothorax 

 and metathorax. Male beak stout, shorter than prothorax, nearly 

 straight; in lateral view nearly parallel-sided, upper surface abruptly 

 deflexed downward toward tip; in dorsal view tapering from antennal 

 insertion to apex, not expanded laterally at antennal insertion; 

 coarsely, deeply, rather densely punctured, pubescence conspicuous 

 to near tip, tip smoother; dorsal margin of antennal scrobe continues 

 to apical third as a carina overhanging a series of deep punctures 

 which appear to form a sulcus. Female beak equal in length to
