Not only are the denticulatioii.s of the cephalic coxae^^ and 

 margins of the pronotum heavier than in any other species of 

 the genus, but the collar of the pronotum also has its dorsal 

 surface supplied with a few minute tuberculations on each side 

 of the medio-longitudinal sulcus. This latter condition is, 

 among the other species of the genus, found only in aS'. nahua 

 (Saussure), there developed to a slightly greater degree. 



The feeble longitudinal carinae of the median and caudal 

 tibiae suggest the Vatid genus Stagniatoptera, as Chopard has 

 remarked. In the female sex these carinae are more prominent 

 and led liehn to describe a specimen of that sex as Stagmatoptera 

 insatiabilis. We do not believe that these carinae are sufficiently 

 developed, however, to warrant assignment of the species to 

 Stagmatoptera. 



In the adult Panamanian males the pronotum ranges from 

 18.3 to 20.2, the tegmina from 36.8 to 37.4 mm., in length; the 

 former from 3.7 to 3.8 in greatest width. 



In the males the marginal field of the tegmina is transparent, 

 hyaline tinged faintly with green toward the costal margin, 

 with a ])road opaque band of white margining the mediastine 

 vein and disappearing opposite the stigma. The latter is 

 subobsolete, longitudinal, weakly suffused with brown. The 

 cephalic femora show three subobsolete transverse suffusions of 

 brown in the majority of specimens, these are wholly obsolete 

 in one, conspicuously intensified in another individual.

 Tli(> distribution of this delicate and handsome little species 

 is known to extend northward into Costa Rica. 



^^ 'lliesc are blunt triangular teeth, much heavier than in the other species, 

 but in our opinion insufficient for generic separation, as are the other features 

 given by CJiglio-Tos in erecting the genus Stauromantis to include this species. 

 Their number is variable, five to seven in our series, given as three by Chopard. 

 The internal surfaces of these tcetli are usually' dark, sometimes ahnost black.
