Length of body 20.5 mm., pronotnm 5.2 mm., tegmina 

 20.5 mm. width 6.7 mm., fore femora 8 mm., hind femora 

 23.8 mm. 



1 cf from Mt. Duht. 



I have the pleasure in naming this beautiful new species 

 after its discoverer, the famous Swedish Entomologist, Dr. 

 Eric Mjoberg. 



Seems to come nearest to G. moultoni and G. dayaka 

 amongst the Borneau species ; further related also with the 

 Sumatran and Malaccan species of the modiglianii-g riffinii- 

 group. Differing from all these already at first view by the 

 bright colour of hind wings. End of cf abdomen also 

 different from the hitherto known cT (comp. Treubia, v, 1—3, 

 p. 226, fig. 84). 



Gryllacris pumila n. sp. (Plate 2, fig. 4, 4a). 



9 . Very near in size and general appearance to G. 

 hamtschi Karny from Southern Sumatra, but differing by the 

 following characters : — 



Occiput with a curved shining black cross band in its anterior 

 region ; from this band arise two length bands of the same 

 colour which are produced till fastigium of vertex, separated 

 from another by a very narrow, pale median line. Cross 

 sulcus between fastigium verticis and frontis black ; inner 

 margins of antennal scrobes also blackish bordered, this colour 

 being produced upon forehead into comma-shaped stripes which 

 are convex against the middle line (all these markings much 

 darker than in fig. 4a on plate 5). Genae not darker than 

 forehead; labrum and mandibles slightly darkened. 

 Antennae pale greyish testaceous throughout. Fastigium 

 of vertex narrow, about IJ times as wide as the first antennal 

 joint, with slightly protruding lateral margins. Clypeus wider 

 and less high than in hanitschi. 



Pronotum pale greyish-yellow, bordered as in G. hanitschi 

 with shining black along all margins except the middle of fore 

 and hind margin of disc. Black markings well defined, 

 arranged like in G. signifera : a short black length line in the 

 middle of disc ; 7- shaped marking very narrow behind, strongly 

 widened in front ; the U-shaped sulcus of lateral lobes broadly 

 bordered with blackish above along its whole length, then this 

 black stripe angulated behind above and produced backwards 

 along the sides of disc.
