Type, male, BMNH, from La Parada, Mexico collected by Sall^. 



Remarks: Jacoby wrote that he had seen only a single specimen 

 of this, a male, which is in the British Museum now. There is one 

 male specimen in the Bowditch collection of the Museum of Com- 

 parative Zoology, labelled "Boucard, Mex. coll.", and one female 

 specimen in the U.S. National Museum from 5 miles east of C. 

 (?Ciudad) del Maiz, 4700 ft., Mexico, collected by R. R. Dreisbach, 

 Aug. 25. 1954, from the Monr6s collection. In this female specimen 

 the third antennal joint is longer than the fourth or succeeding joints.
