ters is present in the species, while it also passes into the following 

 form which is merely a geographic race. 



The size varies considerably, even in series from the same locality, 

 while the coloration is modified by the variable intensity of the 

 blackish or brownish postocular bars which margin the lateral carinse 

 ventrad. The dorsum of the head and pronotum is either uniform in 

 color or supplied with a pair of narrow velvet}^ blaxik lines, which 

 diverge caudad and margin the lateral carinse on their internal edge. 

 These lines are variable in intensity and also in continuity, those on 

 the head sometimes being parallel and again regularly divergent and 

 continuous with their pronotal section. Several individuals from 

 the Misiones and Sao Paulo, Brazil, are more or less completely 

 sprinkled with fine blackish-brown punctations, in this respect resem- 

 bling similarly colored individuals of Chloealtis conspersa and Psolaessa 

 texana. 



The lateral carinse of the pronotum are variable in character, in 

 some individuals being decidedly discontinuous at the transverse 

 sulcus and continuous in others. In the latter specimens the carinse 

 are slightly but regularly divergent through their entire length, 

 while in the other type they are more or less decidedly offset laterad 

 at the sulcus, subparallel on the prozona and slightly divergent or 

 (more frequently) subparallel on the metazona. These two types 

 have no geographic significance, cannot be correlated with size, and 

 in color only that all of the continuous type have the supplementary 

 dorsal lines of black. Some individuals are almost intermediate 

 in the character of the carinse, and similar variation is found in 

 0. pagana minor. 



The typical form of the species ranges from Rio Janeiro, Brazil 

 west to at least Formosa, Argentina, extending south only as far as 

 Resistencia Chaco and Misiones, Argentina, northward and westward 

 apparently grading into 0. p. minor, specimens from Chapada and 

 Corumba, Matto Grosso, Brazil, being nearer cotypes of Giglio-Tos' 

 form.
