ORTHOPTEROUS INSECTS, 



BY CHAELES GIEARD. 



I. DAIHINIA, Hald. 



Gen. chae. — Body rather short, concave above, without any traces 

 of wings ; provided with short and robust limbs ; second and third 

 joints of tarsi, equal ; antennae long and filiform. A row of spines upon 

 the under surface of the femora, more conspicuous in males than in 

 females. 



Syn. — Daihinia, Hald. Proc. Amer. Assoc. Adv. Sc. II, 1850, -346. 



Obs. — The general aspect of this genus is that of Phalangopsis, 

 from which it differs by having " shorter antennae, shorter and more 

 robust limbs." It approximates to Stenopelmatus by the structure of 

 its tarsi, in which the second and third joints are equal. • 



Prof. Haldeman, who traced the distinction between Daihinia and 

 Phalangopsis, proposed to consider the former as a mere sub-genus of 

 the latter. But should the above character prove constant, they are 

 sufficient to raise Daihinia to the rank of a genus ; thus simplifying 

 much the nomenclature. 



Two species of this genus are known — the one herein described and 

 figured, and D. robusta, Hald., an inhabitant of New Mexico. 



1. Daihinia brevipes, Hald. 



Zoology, PI. XV, figs. 9-13. 



Spec. char. — Dnrk brown, mottled with lighter shades , legs short 

 and robust; tibiae shorter than the femora, and strongly spinous; antennae 

 of medium development. 



Syn. — Phalangopsis {Daihinia) brevipes, Hald. Proc. Amer. Assoc. 

 Adv. Sc. II, 1850, 346. 



Description. — The fact that in this species the tibiae are shorter 

 than the femora, contributes somewhat to impress upon it more strongly 

 that character of the genus which consists in being provided with
