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

 lateral expansion nearly parallel to middle, rounded to constricted

 0.03 mm. in diameter, interspaces less than diameter of punctures; 

 basal fovea punctiform, moderately deep. Elytra at hiuneri one-half 

 wider than prothorax at base, 2,8 tunes as long as prothorax, length to

 0.05 by 0.04 mm., with a slight median fm-row. Front femora 3.4 

 times as long as wide. Claws with acute basal tooth. 



Special male characters: Tibiae 2 and 3 with moderately long, 

 nearly simple mucrones. 



Types: I hereby designate the lectotype of this species as the 

 female specimen (USNM 4233) labeled San Diego, Tex. A male 

 cotj'^pe (MCZ 25117) in the Fall Collection has the same data as 

 lectotype. Fall (1898) states that the material on which the species 

 was based was collected by Mr. Schwarz and was in the collection of 

 the U. S. Department of Agricultiu'e, hence the selection of the 

 National Museum specimen as lectotype. 



Material examined: Lectotype, cotype, and Hve specunens. 



Known distribution: 



United States: Texas: Del Rio (MCZ); San Diego (MCZ, USNM). 

 Mexico: Mexico: 30 iiiiles southeast of Mexico City, Julj' 1954, D. G. Kis- 

 singer. 



Remarks: The material from Mexico was taken while beating 

 scrubby oak and acacia bushes.
