Other specimens of the genus are reserved for study, until I shall 

 have had time to go over the extensive writings of Dr. Achille Grififini, 

 who has been doing much original work on the family during the past 

 six or eight years.

The present genus is confined to tropical America, where forms occur 

 from Panama to Bolivia and Paraguay. According to Dr. Achille 

 Griffini there were known at the time when he monographed the genus 

 eight species and one variety. The present collection contains an 

 additional form. x\ll of the described forms are tabulated in Grififini's 

 monograph on pages 190-192.

There are specimens of both sexes of this insect at hand. They 

 come from Santa Cruz de la Sierra, Bolivia, where they were collected 

 by J. Steinbach at an elevation of 450 meters above sea-level. There 

 is also a nymph of what is considered to be the same species. It was 

 taken by the same collector at Puerto Suarez, Bolivia, during the 

 month of November.
