Male Color Variaftt 4. — Like typical male, but with the fourth dorsal 

 abdominal segment covered with ferruginous-red pile, except for a 

 strong admixture of black hairs on its basal middle. One specimen 

 from Ozumba, Mexico — 8,088 feet altitude. 



Habitat. — We have the following certain records for this 

 species : Mexico (Ixtaceihautl, Popocatepetl — 8,000 feet alti- 

 tude, Ozumba, Jalapa), Guatemala (Olas de Moka — Depart- 

 ment Solola) and Venezuela. 



Pidcher is a very appropriate name for this species, for it 

 is indeed a handsome one. It has its nearest ally in ephip- 

 piatjis, the only marked structural difference between the two 

 species being the difference in the form of the squamae of 

 the male genitalia. 



Species of the Dumoucheli Group South of the 



United States.
