Subfam. EUMASTACINM*\. 



If we are to judge from the material at hand, this very remarkable subfamily of 

 locusts, which contains so many imitative forms, is very poorly represented in Mexico 

 and Central America. Nevertheless, as the following table will show, some extremely 

 interesting species are to be met with. In the genus Teicophrys, from Cape San Lucas, 

 Lower California, we have a representative of the Old-World group with dilated frontal 

 costa between the antennae. 



Owing to the comparatively small size and inconspicuous appearance of those forms 

 with stick-like apterous bodies, they are apt to be overlooked by the general collector. 

 Hence, a careful search made by specialists over the country from the Isthmus of 

 Panama to the northern boundary of Mexico and in California will, no doubt, result in 

 the addition of more genera and species. 



For this reason, several of the allied genera and species known to inhabit Southern 

 California or the northern parts of South America are enumerated, these being placed 

 (as in Vol. I. of this subject) within square brackets. 



Table of the genera of Eumastacinge inhabiting the middle portions of America. 



A. Frontal eosta more or less dilated and flattened between the 

 antennae. 



b. Pronotum with the dorsum not tectif orm, plain. Metatarsi of hind 

 legs with both margins denticulate above.
