8. Hemiteles rufithorax. 



Bufus ; capite abdomineque nigris, albo marginatis ; pedibus sordide rufis, anticis basique tibiarum posticarum 



albis ; alis hyalinis, medio apiceque fumatis ; stigmate nigro, subtus pallido. $ . 

 Long. 6*5 millim. ; terebra 1 millim. 



Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 



Antennae as long as the body, a broad white ring in the centre ; scape obscure white 

 on the lower side. Head shining, impunctate, black, the orbits broadly white. 

 Thorax closely punctured ; scutellum aciculate and bearing a few scattered punctures. 

 Metathorax more strongly punctured, its transverse keels obsolete; tubercles stout, 

 longer than broad. The thorax in front, the tegulae, and the metathoracic tubercles 

 clear white. Abdomen aciculate ; the first segment white, with a large black mark in 

 front of the postpetiole ; second and third segments black, broadly white at the apex ; 

 fourth segment entirely black, the rest white. Legs obscure red, the anterior ones 

 pale ; hind coxae blackish, their apices white ; hind trochanters marked with black ; hind 

 tibiae darker than the others ; tips of the tarsi black. Areolet completely open at the 

 apex ; the cloud in the middle is in front of the basal nervure, and does not reach the 

 costa, nor does it extend beyond the brachial cellule. 



B. Abdomen white, banded with black. (Species 9 to 11.) 



9. Hemiteles adultus. 



Hemiteles adultus, Cresson, Proc. Acad. Phil. 1873, p. 173 (?) \

Differs from the next species in having the metathoracic tubercles "prominent, 

 obtuse," the hind coxae entirely yellowish, the first abdominal segment with only a spot 

 on its apex, and the pleura? entirely black ; from H. sexlineatus it differs in the black 

 pleurae, and in the mesonotum being almost entirely black.

Antennae longer than the body, the scape beneath and a broad ring on the flagellum

 punctured than the head, the pleurae not so strongly. Metathorax coarsely punctured 

 and without tubercles or transverse keels. The prosternum, a broad band on the 

 edge of the pronotum, the mesopleurae (except above), the sternum, a large mark
