56 CRICKET-LOCUSTS (GRYLLACRIDAE) . 



Eighth tergite fully twice as long as the preceding one: 

 ninth (fig. lb) strongly arched, with two strongly incurved 

 spines beneath apex. Cerci moderately long, densely haired. 

 Subgenital plate (fig. Ic) semi-circularly rounded at apical 

 margin, by no means excised; styles short, conical, hardly 

 one-third of cereal length. 



cf . Length of body 17 mm., pronotum 3.7 mm., tegmina 

 34 mm., fore femora 7 mm., hind femora 13.5 mm. 



1 cf from Mt. Dulit. 



Belonging to the phryganoides-arctata-grouip, differing from 

 all the hitherto known species of this group by the shape of 

 cT subgenital plate. In colour and general appearance 

 similar to G. sphegidipraeda Karny, but differing from it by 

 its larger size and especially by the longer tegmina. In this 

 latter respect resembling G. phryganoides De Haan, from 

 w^hich it differs by its darker colour, especially along the 

 discal sides, and by the narrower tegmina. Spines of fore 

 and middle tibiae, finally, also being longer than in all the 

 hitherto known species of this group. 



Gryllacris atrata Walker. 



To this species belongs probably 1 9 larva from Mt. Dulit, 

 as it is suggested by the colour of legs. This larva has, 

 however, the forehead darker, reddish castaneous, and the 

 fastigia furnished with distinct, yellow ocellar spots, the 

 lower one being ovate, higher than broad, the two upper ones 

 a little shorter and especially very much narrower. If this 

 should not be a merely larval character, the specimen might 

 belong perhaps to a new local race, characterized by the 

 described coloration characters. This cannot be decided, 

 naturally, from a larval specimen only. 



Gryllacris fasciculata rotimdata n. subsp. (Plate 2, fig. 2). 



Differing from the typical species especially by the much 

 more rounded, nearly cycloid hind wings which are only one- 

 third longer than wide, whilst in the typical species (comp. 

 Karny, Treubia, v, 1—3, p. 68, 233) "presque une fois et 

 demie plus longues que larges" (Pictet and Saussure, 1896). 

 In the typical species the pale cross veins are bordered by 

 sharp, red cross bands, the remaining part of cells whitish 

 hyaline, whilst in rotundata the hind wings are more pink 

 coloured (somewhat too red in the coloured figure on plate 5),
