The type of the genus is F. dugesii Ale man described from 

 Guanajuato, Mexico ; two other forms, which are either strongly 

 marked varieties, or closely allied species, are known from Caracas, 

 Venezuela, and Trinidad, West Indies. These three forms may 

 be distinguished as follows : 



Third antennal joint at most twice the length of the fourth, either entirely 

 ochreous or pale only at base. Head and thorax without definite black 

 markings. 



Third antennal joint almost twice as long as the fourth; fore-wings 

 narrower, more narrowly rounded at apex; fourth furcal running 



into the tip of the wing (Guanajuato, Mex.) dugesii Aleman. 



Third antennal joint only one-third longer than the fourth ; fore- 

 wings wider, broadly rounded at apex ; tip of wing within the 2d 



marginal cell (Caracas, Venezuela) var. ernstii Schwarz. 



Third antennal joint at least two and one-half times longer than the fourth. 

 Head and thorax with well defined black markings ; fore-wings broadly 

 rounded at apex: fourth furcal running into the tip of the wing; third 

 antennal joint black (Trinidad, West Indies) var. cedrelce Schwarz. 



In discussing this paper Mr. Ashmead stated that the very re 

 markable antennas of Freysuila, which resembled in fact those of 

 the saw-fly genus Xyela, would warrant the erection by Mr. 

 Schwarz of at least a new tribe. 



Some discussion ensued between Messrs. Gill, Ashmead, and 

 Schwarz as to the advisability of forcing a form like this into the 

 dichotomous table in preference to putting it aside and forming a 

 new group. The discussion took a general turn, and Messrs. 

 Gill and Ashmead favored the last view and Mr. Schwarz the 

 former. 



JUNE 17, 1897. 



President Marlatt in the chair and Messrs. Gill, Benton, Motter, 

 Pratt, Waite, Chittenden, Ashmead, Schwarz, Patten, Howard, 

 Heidemann, Fernow, Hine, and Matthis also present. 



Mr. Schwarz exhibited specimens of a probable new species of 

 the genus Telegeusis Horn (family Drilida?) , collected by Mr. Hub- 

 bard at the Hot Springs (southwestern foot of Galiuro Mts.), 

 Arizona, and spoke at some length of the remarkable palpi pos 

 sessed by this genus. Mr. Ashmead asked why the palpi in 

 certain genera in many groups are so prolonged. He noted a
