LOCUSTIDJS. 407 



rounded. Suhgenital lamina elongate, with two clavate styles. Legs short, 

 thick; fore femora and four anterior tibiae unarmed; middle femora and 

 hind tibiae wiih two or three rudimentary spines; hind femora about two- 

 h'fihs of the length of the fore wings, with one row of eight small spines. 

 Wings of equal length. Fore wings minutely reticulated, rather narrow ; 

 costa and interior border nearly straight; three irregular rows of areolets 

 between the scapular vein and the costa; scapular and exteruo-medial vein 

 contiguous for about two-thirds of the length, where they part and are lost 

 in ramifications; three irregular rows of areolets between the exierno- 

 medial and the anal vein, and one row of regular quadrate areolets between 

 the latter and the interior border. Hind wings pellucid; veins' green. 

 Length of the body 12 lines ; expansion of the fore wings 33 lines. 



It much resembles P. breviusculus, but the spines of the hind femora 

 are fewer and smaller, and the areolets in the middle part of the fore wings 

 are more numerous and complete.
