228 OETHOPTEEA. 



b*. Rostrum or fastigium of the vertex in front, rounded. Crest of the 

 pronotum elevated posteriorly. Tegmina about as long as, or a little 

 shorter than, the abdomen, their apex acuminate. Wings with the 

 disc red 4. bruneri, Rehn. 



1. Colpolopha latipennis, Stal 1 ? (C. sinuata, Tab. II. figg. 25, 25 a, 2 .) 

 Colpolopha latipennis, Stal, Bih. till K. Svensk. Vet.-Akad. Handl. v. no. 9, p. 19 (1887) \ 



Hab. Central America {Rev. T. Heyde, in coll. L. Bruner). — South America, Peru 1 . 



The insect doubtfully referred to as C. latipennis, Stal, was first determined as 

 C. sinuata, which has the frontal costa sulcate to the fastigium, but a more careful 

 study has decided me to place it here instead. The single specimen seen, a female, 

 was given to me by Mr. Heyde. 



2. Colpolopha Obsoleta, Serville.

Hab. South America, Colombia and British Guiana (coll. L. Bruner), Peru 2 . 

 Probably extends to the Isthmus of Panama. 



3. Colpolopha siimata, Stal.

While no specimens of this species are at hand from our region, there is scarcely 

 any doubt but that it will be found as far north as Costa Rica, if not in Nicaragua as 

 well. In fact, while collecting in the former country several years ago, a locust was 

 seen but not taken by the writer that was referred to C. sinuata. 



4. Colpolopha bruneri, Rehn. 



Colpolopha bruneri, Rehn, Proc. Acad. Nat. Sci. Philad. 1905, pp. 406-408 \ 

 Hab. Costa Rica (Biolley), Monte Redondo (L. Bruner 1 ). 



One male and two females of this species were captured by the present writer in 

 Costa Rica, in the month of February, and various others have been found by 

 Prof. Biolley. It is variable both in size and colour, as well as in some minor 

 structural characters. Specimens are at hand that exceed Rehn's measurements by at 

 least 5 millimetres, while others lack nearly as many in being as large as his types. 

 The pointed or acuminate tegmina and vermilion wings are sufficient characters to 

 separate C. bruneri from all other described forms.
