1910] American Species of Plat ymeto pins 223 



They differ only in being slightly larger and paler. This species 

 is very close to acutns with which the typical form is almost 

 identical in color and markings but its small size, remarkably 

 long and acute vertex and the short male pygofers preclude its 

 reference to that species.

 Proc. lowu Acacl. Sci. iv, p. 193, 1897. 



This is a very small and somewhat greenish species with a 

 vertex formed about as in acutns; face greenish-white, very 

 slightly infuscated on the base of the front where the angular 

 white line is distinct; markings on the vertex and pronotum 

 nearly obsolete but the five pale vittae of the latter are generally 

 discernable; abdomen mostly black in the male, rarely so in the 

 female; elytra closely but lightly reticulated. Last ventral 

 segment angularly produced in the female; valve of the male 

 obtusely triangular; plates nearly as long as the valve on their 

 suture, triangular, blunt at apex, considerably exceeded by the 

 pygofers. 



This, one of our smallest species, is found throughout the 

 warmer portions of the central and southern states from Iowa 

 to Florida.

 20th Rcpt. N. Y. State Ent.. \^. 518, 190.5. 



Prof. Osborn has very kindly sent me one of his male types 

 and I have examined the female in his collection. This is the 

 smallest species known to me and has been reported from the 

 type locality only: Long Island, N. Y. The female is distinctly 

 larger with a longer vertex than the male. It has a light green- 

 ish color with coppery reflections ; the round areolar spots of the 

 elytra are confined to the apical and anteapical areoles; the costa 

 is hyaline with the oblique veinlets dark and the abdomen is 

 marked with black. The male is smaller with a much shorter 

 vertex; its color is a bright fulvous becoming yellowish on the 

 head; the elytra are subopake, almost unicolorous on their base 

 but becoming recticulated with brown on their apical and ante- 

 apical areoles where the round white spots are fairly distinct ; 

 oblique veinlets of the costal areole almost obsolete. In both 

 sexes the base of the front is feebly infuscated with the pale 

 angular line discernible.
