half of the abdomen and the wings are vestigial. This is the 

 most northern known record for the species.

 Two males. 



We have also seen a specimen from the collection of the Mu- 

 seum of Comparative Zoolog}', labelled "Mendez, Thayer Exp.," 

 but we are unable to place the locaUty. When compared with 

 a male of cantans Saussure, from "Southern British Guiana," in 

 the collection of the Academy, the more evident features of dif- 

 ference appear to be the generally smaller size of hedyphonus, 

 and the less strongly transverse speculum of the male tegmina of 

 the sex; the transverse veins of the speculum in hedyphonus are 

 more oblique and regularly spaced at their junction with the 

 juxta-humeral portion of the specular margin, while in cantans 

 they are more transverse, and at their junction with the same 

 margin they are more bunched. The number of these veins 

 varies from three to four, while the number of oblique veins in 

 hedyphonus is seven to eight, and in our cantans, four to six."^ 

 Bruner^* was correct in removing Giglio-Tos' Ectecous horellii 

 from this genus. We have a paratypic pair (San Francisco, 

 Bolivian Chaco), received from Borelli, and the species has no 

 affinity with true Ectecous. It appears, instead, to belong in or 



'2 We have used material of cantans from other localities, to be recorded 

 later, in securing these counts.
