Thomas). It occurs throughout all of tropical and sub- 

 tropical America, and has, therefore, received several names. 

 Giglio-Tos vef erred it to 'froclii/rhoch is OoreaNs Sauss. (Boll. 

 Mus. Zool. ed Anat. Comp. di Torino, IX, No. 184, p. 14) but 

 later corrected the error. 



GENUS COELOPTERNA, STAL.

This insect was made the type of a distinct sub-family by 

 Stal; but Brunner v. Wattenwyl in his "Revision du Sys- 

 teme des Orthojjteres" places it along with the OEdipodinae 

 where I am willing to let it remain at present. Blanehard 

 redescribes and figures this insect under the name PauJ'niki 

 iiufcosa (D'Orbigny, Voyage dans L'Amer. Merid., Vol. VI. 

 Pt. 2, Insectes, p. (216), PI. XXVII, Pig. (3), and Giglio-Tos 

 (Boll. Mus. Zool. ed Anat. Comp. Torino, IX, No. Is4, p. 7) 

 describes a new variety with abbreviated wings as Coelopterna 

 acuminata var brerijicnnis. The insect is one that lives ujjon 

 aquatic plants and often must swim, hence the jDeculiar devel- 

 opment of hind tibiae and their spurs. 



GENUS BUPONACRIS, WALKER. 



B. terrestrix Walk. Four specimens of this peculiar, 

 robust, wingless locust were taken at Gregory Bay on the 

 Straits of Magellan by some member of the U. S. Pish 

 Commission force during the cruise of the steamer Albatross 

 for the years 1887-88. Walker's specimen was also taken at 

 the same locality, hence Saussure is mistaken when he dis- 

 credits Walker's statement as to habitat of this insect 

 (Additamenta ad Prodromum OEdipodiorum, p. KKi, foot 

 note). 



B. — spy Several specimens were observed in the collection 

 of the La Plata Museum that evidently belong here. They 

 seemed to belong to at least two species, and, if my memory 

 does not fail me, were taken in the Territory of Chubut.
