or yellowish filamentous excretions of a waxy .nature. 

 The function of this is not known but may possibly be 

 connected with oviposition. 



Very little is known of the habits and life history other 

 than that some are tree-inhabiting and others grass-feed- 

 ing forms. 



Key to the genera 



1. Sides of frons produced at sides and auriculate or ear-like, when 

 viewed from above ; elytra not tectif orm nor adpressed to the sides. 

 Bothriocera Burm. 



... Sides of frons not produced or auriculate, except very rarely, in 

 which case the elytra are upright and adpressed to the sides 2 



2. Elytra brachypterous, frons broad oval Monorachis Uhl. 



... Elytra macropterous, frons more elongate, elytra more or less 



dilated behind the claval apex; mostly obscure, more or less opaque 



dark species, the elytra adpressed Cotyleceps Uhl. 



Elytra not dilated behind the apex of clavus, not adpressed to 

 the sides, almost always pellucid and transparent 3 



3. Vertex extremely narrow, reduced to a mere slit between the 



eyes; scutellum 5-carinate Oecleus Stal 



Vertex broader than long, or at most not much longer than broad..4 

 Scutellum 5-carinate Oliarus Stal 



... Scutellum tricarinate; posterior tibiae armed with two or three 



spines Cixius Latr. 



... Scutellum tricarinate; posterior tibiae without spines.. Myndus Stal 



THE GENUS BOTHRIOCERA BURMEISTER 



The species belonging to this genus are all of small size 

 with the larger and more showy species in South America. 



Briefly characterized as follows: Upper portion of the frons 

 produced at the sides into short ear-like processes, which when viewed 

 from above, look like two small blunt horns. The frons and clypeus 

 together form an isosceles triangle, with the vertex of the head as 

 its base. Ocelli, especially the frontal, very distinct. Pronotum 

 extremely short, the scutellum large with the carinae not strongly 

 marked. Elytra much widened behind and rounded. 



Haplotype of the genus: Bothriocera tinealis Burm. 



Van Duzee in his "Catalogue of Hemiptera" gives B. 

 tinealis var. westwoodi Stal, B. signoreti Stal (may not be 

 distinct from preceding), B. undata Fabr., and B. bicornis 

 (?) Fabr. (North American localities may refer to undata) 

 as occurring in Florida. I have not been able to definitely 

 place the B. undata which may not be distinct as the orig- 

 inal description is very meagre and inadequate.
