The female of this species, which I beheve has never been 

 described, shows no characters differing essentially from those 

 of the male. The ovipositor is nearly twice as long as the pro- 

 notum and apically rounded and dentate. The measurements 

 of this sex are as follows : 



Length : pronotum, 5.5 to 6 mm. ; tegmina, 38 to 40 mm. ; 

 posterior femora, 26 to 38 mm.; ovipositor, 10 to 11 mm. 

 Width : tegmina at widest part, 8 mm. ; ovipositor mesially, 

 3 mm. 



The color of this species as represented by the six specimens 

 here recorded varies from decidedly greenish to reddish brown, 

 the latter very likely due, at least in part, to changes after death. 

 There are a few obscure dots along the middle of the tegmina 

 of all the specimens, noticeable only under a glass. 



Plagiopleura gracilis Brunner.

One 9 , no date. Schunke. 



There seems little question as to the synonymy of the genus 

 Buthyrrhachis with Plagiopleura and Kirby's use of it as a dis- 

 tinct genus appeared indefensible. Brunner himself very 

 clearly states that it is to be dropped (Verb, zool.-bot. Ges. 

 Wien, vol. xli, p. 177 (1891)), though his statement there that 

 the only species is a Parableta is an error, what he intended to 

 write being really Plagiopleura instead of Parableta, as shown
