Zoniopoda fissicauda Bruner. 



1906. Zoniopoda fissicauda Bruner, Proc. U. S. Nat. Mus., XXX, p. 653. 

 [Sapucay, Paraguay.] 



Goyaz, State of Goyaz. One female. [Hebard Cln.] 



This specimen, which is clearly the present species, has lost some 



of the brilliancy of its original coloration, as if it had been exposed 



to the continued action of a strong kilhng medium. It is slightly 



smaller than the measurements of the same sex given by Bruner. 



The two localities are the only ones from which the species is known. 



Zoniopoda collaris Bnmer. 



1911. Zoniopoda collaris Bruner. Ann. Carneg. Mus., VIII. pp. 58, 60. 

 [Chapada, Matto Grosso, Brazil.] 



Rio Verde, State of Goyaz. Three males. [Hebard Cln.] 

 These specimens agree with the original description of the unique 

 type except that all the pale areas are slightly pinkish, which, how- 

 ever, we feel is not normal but due to chemical action of a killing 

 medium. The species is known only from the two localities given 

 above. 



Diponthus bilineatus new species. (Plate X, figs. 13 and 15.) 



A close ally of D. crassiis Bruner (plate X, figs. 14 and 16), from 

 northeastern Argentina and eastern Paraguay, differing in the 

 slightly more elongate form (for the sex), in the slightly less de- 

 clivent fastigium, in the proportionately more longitudinal pro- 

 notum, the more distinctly angulate caudal margin of the disk of 

 the same, in the slightly more elevated medio-longitudinal section 

 of the metazona, in the more obhque caudal margin of the lateral 

 lobes of the pronotum, in the more elongate, narrower tegmina, in 

 the more elongate male cerci, which surpass the apex of the supra- 

 anal plate and have their distal extremity distinctly decurved, and 

 in the coloration — the tegmina being non-reticulate but with the 

 humeral trunk and the anal angle contrastingly lined with yellow 

 on an olive-green ground, the caudal femora pinkish with a weaker 

 medio-longitudinal line on the external face and with the caudal 

 tibiae lacking the dark Hning of crassus and reddish on the internal 

 face, while the wing is more greenish hyaline, without the l)luish 

 wash seen in crassiis. 



Type — cf; Santa Catharina, Brazil. [Hebard Collection, Type 

 no. 411.] 



Size large (for the genus); form as in D. crassus; surface of the 

 head, pronotum and pleura strongly and closely cribroso-punctate. 

 Head with the vertex and fastigium considerably declivent, nar-
