TROPINOTUS Serville. 



Since Paraguay seems to be the center of a])undance of the species 

 belonging- to the genus TroptnotuH it might ))o well to append a brief 

 synoptic table lor separating all the known forms, together with those 

 here described. 



TABLE FOR DETERMINATION OF SPEOIES. 



((. Crest of the pronotum more or less crenulate or even serrnlati^ jjosleriorly. Genic- 

 ular angles of hind femora acute, a little lengthened. 

 h. Tegmina and body cinereous, testaceous, or ferruginous, usually more or less 

 mottled with brown. 

 c. The markings of tegmina large, forming more or less well-defined bands. 

 (}. Hind tibite 12-spined. The wings with the anterior field as well as disk 



colored bright rose rosulmtus Stal 



(/(/. Hind tibite 9-10 spined. The anterior field of wing more or less infuscated. 



e. Hind femora very long, reaching considerably beyond the tip of abdomen 



in both sexes. Crest of pronotum deeply cleft by all three sulci, the 



lobes distinctly separated discoideus Serville 



ee. Hind femora shorter, only reaching the tip of abdomen (female) or but 



little surpassing it (male). Crest of pronotum less deeply cleft, the 



lobes closely approximate. 



/. Larger; general color cinereous or testaceous, the maculation of tegmina, 



composed of several transverse bars and distrilmted over most of wing. 



g. Wings long, narrow. Carina of pronotum less arched, confined to 



Brazil and southward unyulatus Stal 



gg. Wings broad, shorter. Carina of pronotu.u high and strongly 



arched. Yucatan and Honduras mexicanus, new species. « 



ff. Smaller; general color ferrugineo-testaceous, the tegmina with but a 



single triangular basal maculation lichidzi Bruner 



cc. Markings of tegmina small, irregularly scattered over the wing save for a 

 row in basal half of discal area. 

 d. Pronotum short, the crest low, and but little produced posteriorly. Hind 



tibiai with 9 spines in outer row . . .' modestus Giglio-Tos 



dd. Pronotum longer, considerably produced posteriorly. Hind tibia? with 



10 spines in outer row conspersus Bruner 



111). Tegmina and body uniformly colored, without maculation or conspersing. 



c. Tegmina, as well as entire body and legs, green insignis Giglio-Tos 



a: Tegmina, body and legs uniformly dull brown save a paler dorsal stripe on 



the former - affinift, new species 



((«. Crest of pronotum smooth posteriorly. Genicular angles of hind femora shorter 

 and more rounded. 

 b. Hind tibite provided with fewer (10) spines in outer row. General color, dark 



cinereous regularis Bruner 



h}>. Hind tibite provided with more (11-19) spines in outer row. Color variable. 



c. Color largely green; the discal area of tegmina with or without dark spots. 



d. Posterior femora punctate, and with all the carinse nigro-serrate. Hind 



tibiae armed with 11 or 12 spines on outer side (San Leopold, Central 



Brazil) scabripes Stal 



"These two species are before me as I write, hence are included herewith. The 

 Mexican species will be described in the Biologia Centrali Americana when the 

 proper place is reached. The other is sufiiciently distinct to be recognized by the 

 diagnosis given here. This last may also occur in Paraguay.
