VOL. XXXVI. 



STENACRIS CYLINDRODES (St^l). 



1860. Opsomala cylindrodes Stal, Kong. Svenska Freg. Eugenies Resa, Ins., 

 p. 325 [Rio Janeiro, Brazil]. 



Corumba, Matto Grosso, Brazil. March; lowland. (H.H.Smith.) 

 Three males, two females. 



Bonito, State of Pernambuco, Brazil. January, 1883. (A. Koe- 

 bele.) One male. 



The Cormnba specimens are quite uniform in size and color, the 

 pale lateral bar being visible in all, but quite weak in one female. 

 The Bonito individual is distinctly smaller with the vertex blunter 

 than is the case in the other representatives, but the genitalia are 

 of exactly the same character. 



This species is now known to range from the State of Pernambuco 

 to that of Matto Grosso and the Chaco of Argentina (Resistencia). 



STENACRIS GRACILIS (Giglio-Tos). 



1897. A[rnilia\ gracilis Giglio-Tos, Boll. Mus. Zool. Anat. Oomp. Torino, XII, 

 No. 302, p. .30. [San Lorenzo, Jujuy, Argentina.] 



Corumba, Matto Grosso, Brazil. March; lowland. (H.H.Smith.) 

 Three males. 



These specimens are of much the same size, and have a dark dorsal 

 edging to the lateral pale bar. 



It is of interest to note that the genus Leptysma presents much the 

 same types of male subgenital plate noticed in this genus, while at 

 least one species of that genus has the pale lateral bar supplied with 

 a darker edging as in this species. 



The form is now known from the type hx'ality, San Bernardino, 

 Paraguay (Bruner) and Corumba, Brazil. 



STENACRIS COCCINEIPES (Bruner). 



Corumba, Matto Grosso, Brazil. March; highland. (H. H. 

 Smith.) One male, one female.

OXYBLEPTELLA PULCHELLA. new species. 



Types. — Male and female; Chapada, Matto Grosso, Brazil. June. 

 (H. H. Smith.) No. 12089. U.S.X.M.
