greater than width of frons ; first segment equal in length to next three ; 

 second segment of male shorter than next two, of female more elongate, 

 equal to next four segments combined; club 0.18 by 0.07 mm. Eyes 

 moderately prominent; frons slightly wider than dorsal tip of beak, 

 with a shallow median depression and one lateral row of punctures. 

 Prothorax slightly wider at base than long, middle slightly narrower 

 than base, apex three-fourths as wide as base; sides beyond basal 

 lateral expansion slightly diverging to middle, rounded to constricted 

 apex; in profile dorsal surface slightly arcuate; punctation 0.03 mm. 

 in diameter, moderately deep, interspaces appear convex, alutaceous, 

 range in width from one-half to equal to diameter of punctures; basal 

 fovea moderately deep, extending one-third the length of the pro- 

 thorax. Elytra at humeri slightly more than one-third wider than 

 prothorax at base, 2.5 times as long as prothorax, length to width as 

 9:7; elytral intervals somewhat convex, equal in width to two striae, 

 with one row of punctures, punctures somewhat confused at base of 

 interval 3, intervals smooth; striae fine, moderately deep. Scutellum 

 elongate-triangular, 0.09 by 0.05 mm., with a moderate median furrow. 

 Front femora 3.2 times as long as wide. Claws with acute basal tooth. 



Special male characters: Tibia 1 armed with minute, blunt micro; 

 tibiae 2 and 3 armed with moderate, acutely dentate mucrones. 



Types: Holotype male (USNM 63416) from San Luis PotosI (near 

 the town of Antiguo Morelos in Tamaulipas), Mexico, July 1954, 

 D. G. Kissinger. Allotype female (USNM), same data as holotype. 

 Forty-six paratypes, same data as holotype (24 in the collection of the 

 author and 2 in each of the following: AMNH, BMNH, CAS, CIS, 

 CNC, CU, INHS, UC, UK, UM, UMD). 



Remaeks: It gives me much pleasure to name this species in honor 

 of Dr. Ernest N. Cory in recognition of his years of service to ento- 

 mology.

 Apion (Trichapion) imitator Wagner, Arch. Naturg. Berlin, vol. 78, p. 106, 1912. 



Description: Length, 2.25 mm.; width, 1.10 mm. 



Robust, black. Pubescence fine, white, sparse on dorsal surface, 

 coarser and denser on sides of prothorax, mesothorax, and metathorax. 

 Male beak shorter than head and prothorax, one-third longer than 

 prothorax, slightly, evenly curved; in lateral view attenuate from 

 antennal insertion to apex; in dorsal view expanded laterally at 

 antennal insertion, strongly attenuate to apical third, tip slightly 

 expanded, somewhat compressed in apical third; punctured and 

 sparsely pubescent to near apex, tip smoother, bare, a line of con- 

 fluent punctures above antennal insertion appears as a sulcus, extends
