This specimen is inseparable from material from the United 
States. We also have specimens (three males) from as far south 
as Mendoza, Province of Mendoza, Argentina (Haarup), in the 
collection of the Academy. The species is seen to have a very 
great distributional range, being in the class with Gryllus assimilis 
and Miogryllus vertical is.-’’ The Para and Mendoza specimens 
are all macropterous.

We have compared this specimen with material from Belize, 
British Honduras (one male), San Alarcos, Nicaragua (one female) 
and Trinidad (two males), in the collection of the Academy, and 
find them to be specifically inseparable. As Bruner has stated^* 
there is quite a wide range of variation in specimens, so far as 
color is concerned and to a certain degree in size. The antennal 
coloration is one of the markedly variable features, and in the 
Para specimen the antennae are fuscous, with the proximal 
segments marked dorsad and the median segments disto-dorsad 
with yellowish. 
The species has been recorded from as far south as Corumba, 
Matto Grosso, and Jacore, Minas Geraes, Brazil, and Puerto 
Suarez, Bolivia, west to Tarma, Peru, east to Trinidad and 
French Guiana (Nouveau-Chantier).

Bruner (Ann. Carneg. Mus., x, p. 359, (1916) ) has continued to use 
histrio and histrionicus Saussure as valid specific names, although they were 
synonymized under minuta by Scudder as long ago as 1902 (Psyche, ix, p. 
308). Rehn and Hebard recently have made some remarks (Proc. .Acad. 
Nat. Sci. Phila., 1916, p. 284, (1916) ) concerning the variability of minuta^ 
chiefly in reference to the presence or absence of subapical natatory lamellae on 
the dorsal margins of the caudal tibiae.
