Thyrso«era discoidalis (Burmeister). 



1838, Blaita discoidalis Burmeister, Handb. d. Ent., Bd. ii, Abtb. ii, pt. i, 

 p. 498. 



One specimen, female; Orizaba, Vera Cruz, June 6, 1899. 

 This name is usually quoted as ducicollis, but an examination of 

 Burmeister's work will show that the original is discoidalis. 



Periplaiieta americana colorata n. subsp. 



Periplanefa americana var. Saussure, Miss. Scient. Mex., Orthoptera, p. 72; 

 Saussure and Zehntner, Biol. Cent. Amer., Orthoptera, p. 74. 



Type : male ; Cuernavaea, Morelos, vi. 



This deeply colored form of P. americana was knowu to a number 

 of writers, who never applied a distinctive name to it. It difters 

 from the typical americana in the much deeper and richer colors, in 

 this very much resembling P. anstralasice as Saussure and Zehntner 

 have pointed out (Biol., Cent. Amer., Orth., p. 74). Any confusion 

 with P. australasice is prevented by the form of the supra anal plate. 



General color deep burnt sienna (Ridgway's Nomenclature of Colors), the 

 elytra becoming orange-ochraceous toward the tips, the whole with a purplish 

 iridescence. Pronotum burnt umber, posteriorly with a collar of ochre, the pos- 

 terior margin black. Lower surface much paler. Auteunse dark brown. 

 Measurements : 



Length of body ...... 26.6 mm. 



Length of pronotum 8.0 " 



Length of elytra 23.25 •' 



Breadth of elytra 8.0 " 



A specimen in my collection, from Philadelphia, approaches this 

 form, but has the straw-yellow on the pronotum unclouded and 

 distinct.
