A REVISION OF NORTH AMERICAN CHRYSOBOTHRINI 9 



Redescribed from one of the two female cotypes in the United States 

 National Museum, collected on the Esperanza Ranch, Brownsville, 

 Tex., June 20, by Charles Schaeffer. This specimen is designated as 

 the lectotype. 



Male. — Similar to the female in external characters. 



Type locality. — Esperanza Ranch, Brownsville, Tex. 



DISTKIBUTION 



From material examined : 



Texas: Brownsville (Esperanza Ranch) (Charles Schaeffer). Brownsville, 

 June 10, 1924 (J. N. Knull). 



Also recorded in the literature by Schaeffer from San Tomas, 

 Brownsville, Tex. 



Host. — The larval habits are unknown, but the adults have been 

 taken in small numbers at the type locality from the branches of 

 Texas ebony (Pithecellohium fiexicaule (Bentham) Coulter) by 

 Charles Schaeffer, who writes that no specimens were taken on any 

 other trees. This tree was formerly known as Acacia fiexicaule 

 Bentham. Chamberlin (1926) states that the larva works in Acacia 

 fiexicaule, but this may be a misstatement of Schaeffer's note in the 

 original description. 



No variation worthy of note has been observed in the three ex- 

 amples (two females and one male), except in size, which ranges 

 from 9 to 10.25 mm. 



This species resembles calcarata Chevrolat, but it differs from 

 that species in being smaller and more slender, and in having the 

 zigzag fascia on the elytra bright green, the posterior angles of the 

 pronotum converging, and the underside of the body greenish. The 

 writer has been unable to find any external characters for separating 

 the sexes.
