294 BRAZILIAN ORTHOPTERA 



material as signatipes a number of times, but, in the light of the 

 series now before us, we find that our references were correct in 

 but a portion of one lot, i. e. the Bonito, State of Pernambuco 

 and Espirito Santo, Brazil, representatives.^^ The other refer- 

 ences by us of material as signatipes all should be placed under 

 chapadensis and caeruleipermis.^ The specimen supposed to be 

 from St. Thomas, West Indies," we feel is erroneously labelled, 

 being obliqua probably from the State of Pernambuco, Brazil. 



The specimens before us have strongly decided coloration 

 contrast; in the case of certain of the specimens this is due to 

 alcoholic immersion, but not in all. The size is uniformly small, 

 as said by Thunberg similar to that of "Gryllus apricarius" 

 { = Siauroderus apricarius). The lateral markings of the caudal 

 femora are strongly indicated in all, while the externo-ventral 

 face always shows some black, but this may be broken up 

 into two areas (aside from the genicular infuscation) by a pale 

 area.

After careful study of the original descriptions, the present 

 material and a cotypic pair of meridionalis from Demerara, 

 loaned by Prof., Bruner, we feel the above synonymy to be cor- 

 rect. Kirby considered dilecta to be the same as signatipes 

 { = ohliqua), but its original dimensions appear to be too large 

 for that form, to which, however, the present species is very 

 closely related. 



The range of the species extends from British Guiana south to 

 Victoria, State of Espirito, Brazil and Santa Cruz de la Sierra, 

 Bolivia.
