58 CRICKET-LOCUSTS (GRYLLACRIDAE). 



nearly straight, without humeral sinus. Sulci of lateral lobes 

 well impressed, space between them strongly arched. 



Tegmina scarcely overreaching the hind knees, pale 

 yellowish, veins tawny (except the praecostals) . Venation 

 according to type IV. 3 or 4 dark brown praecostals. Costal 

 vein simple, costal area distinctly widened distad. Sub- 

 costal vein simply forked close before the tip ; subcostal area 

 scarcely half as wide as the costal one in distal part. Radial 

 vein and radial sector each simply forked close before the end ; 

 sector arising from radial stem about in the middle of tegminal 

 length. Medial vein simple, arising from radial stem in the 

 middle between tegminal base and sector base (on right 

 tegmen) or nearer to the latter (on left tegmen). Cubital 

 vein simply forked basad (on right tegmen) or distad from the 

 middle (on left tegmen). 5 anals (inch Cus), the two last 

 ones with a very short common stem, the last one ending 

 already before the middle of tegminal length. 



Hind wings strongly cycloid, dark blackish-grey in basal 

 part, bright orange-yellow with dark bands along cross veins 

 distad; these cross bands well defined, becoming gradually 

 narrower towards the outer margin, practically wanting along 

 fore margin. 



Legs stout, moderately long, tawny: fore knees broadly 

 black, middle and hind lesfs practically unicolorous, with a very 

 fine single dark line along the knee joint. Fore and middle 

 tibiae each with 5 pairs of very long, concolorous, movable 

 spines. Hind femora on outer margin with 6—7, on inner 

 one with 8-10, small, dark spines; hind tibiae outside with 6. 

 inside with 5—6 dark spines. 



Abdomen pale brownish-yellow, concolorous apical parts 

 scarcely darker. Eighth segment strongly produced, about 

 three times as long as the preceding one, length 3.5 mm. 

 Ninth segment shorter than the eighth, in basal part descend- 

 ing backwards, then angulated and descending forwards, in 

 this subvertical region with a fine median sulcus more strongly 

 impressed in its lower part ; apical margin emareinate, with 

 arched, rounded lobes; no spines \asible, perhaps obtected by 

 the subgenital plate. Cerci moderatelv long and stout, stroufflv 

 pilose, about as lonsf as the eio-hth segment. Subgenital 

 plate (fig. 2) broadly emarginated in the middle of hind 

 margin, with rounded lobes; styles inserted laterad, slender, 

 not quite half as long as the cerci,
