 (Hempel, A. N. S. P.) 



The coloration of these two specimens is generally similar, but one 

 has a longitudinal pale green bar on the proximal portion of each teg- 

 men. This specimen also has a median line on the head and pronotum 

 quite dark, while the other individual is devoid of any striking markings. 

 Amblytropidia trinitatis Bruner.

The Venezuela male is inseparable from the topotypic specimen. The 

 range of the species is considerably extended by the ^^enezuela record.

 Amblytropidia mysteca (Saussure). 



The material previously recorded by the author as A. mysteca from 

 Cuernavaca, Texolo, Uruapan and Patzcuaro, Mexico, has been re- 

 examined, and in all cases represents mysteca as understood by Bruner. 



The genus Sinipta Stal is a rather aberrant member of this group, 

 chiefly differing in the depressed, subensiform antennoe, which, how- 

 ever, does not appear to be sufficient to remove it from association 

 with Amblytropidia, some species of which have the antennae some- 

 what depressed. 



ORPHULELL^. 



The genera generally accredited to this group are with two excep- 

 tions, Calephorus and Comacris, American. The genera examined by 

 the author in this connection are given below, with their apparent 

 positions as far as can be expressed in a linear arrangement. 



Calephorus Fieber { = Oxycoryphus Fisher). 



Parorphula Bruner. 



Sisantum Bruner. 



OrphuUna Giglio-Tos. 



Orphulella Giglio-Tos. 



Clinocephalus Morse. 



Dichromorpha Morse. 



Chloealtis Harris. 



Cocytotettix n. n. { = Fenestra Bruner, not of Giglio-Tos). 



Toxopterus Bolivar.
