71. Metioche americana Chopard? 



Metioche americana Chopard, Ann. Soc. Ent. France, LXXXI (1912), p. 406, 3 figs. 

 Habitat. — Originally described from La Forestiere, French Guiana, 

 where it was collected in April. The present author is in possession 

 of a male from Demarara, British Guiana, where it was collected early 

 in 1 901 by a Mr. R. J. Crew. The Carnegie Museum material also 

 contains a female specimen from Chapada, Brazil, which seems to 

 belong here. It was taken in April by H. H. Smith. 



Genus Cyrtoxipha Brunner.

The insects which compose the present genus are well scattered 

 over the warmer parts of the earth, very sparsely so in the temperate 

 regions, but rather plentifully in the tropics, especially of South 

 America and Oceanica. A few also have been recorded from African 

 regions and the islands of the Indian ocean. 



The genus is separable into several sections based on variations in 

 structural features, such as form and texture of tegmina, length of 

 wings, shape of the anterior tibiae and their auditory foramina, color, 

 size, etc. Up to the present time about thirty so-called species have 

 been named. The descriptions of these have been so varied, however, 

 that it is next to impossible for one to draw up a workable synoptical 

 key for their separation. 



The material now at hand represents quite a number of forms in 

 addition to those here listed. Some of these latter are represented by 

 single specimens, others by imperfect ones, and still others by several 

 individuals showing variation in both size and color. In order to 

 properly classify our American species of the genus much close collect- 

 ing is necessary in all of the regions inhabited by its members. Rather 

 full notes on their haunts, habits, and life-history are also much needed 

 for use in such a study. Four new forms are described in the present 

 paper. Others no doubt are at hand, but for one or more reasons 

 are put aside for future study.
