236 Mr. J. L. Hancock’s Studies of the 
Section TETRIGLA, Bolivar. 
Genus PARATETTIX, Bolivar. 
I recognize four Bornean species of Paratettiz, which 
may be distinguished by the following key *— 
1. Pronotum somewhat broad between the 
shoulders ; the lateral lobes conspicuously 
reflected outwards, triangular and acute ; 
first two basal pulvilli of the first tarsal 
articles spiculate : : 
2. Pronotum narrower between the shoulders ; 
the lateral lobes little produced outwards, 
and angulate-subacute ; the first two basal 
pulvilli of first tarsal articles not spiculate angulobus, sp. nov. 
3. Posterior angles of the lateral lobes of pro- 
notum narrowly rounded ; vertex of head 
strongly narrower than one of the eyes; 
length of pronotum from 9 to 12 mm. . histricus? Stal, 
4. Posterior angles of lateral lobes subtriangular, 
indistinctly turned outward; vertex of 
head narrowed forward, subequal or little 
narrower than one of the eyes; pronotal 
process often extended as far as the wings; 
variabilis, Bol. 
length of pronotum from 12 to15 mm. .  lineatus, sp. nov. 
1. P. variabilts, Bolivar, Ann. Soc. Ent. Belg. xxxi, p. 276, 
1887. 
Three examples from Kuching, N.W. Borneo, R. Shelford; 
Oxford Museum. 
2. P. angulobus, sp. nov. 
A very slender-bodied species, with prominent globose eyes, fusco- 
or grayish-ferruginous; vertex ascendant forward, strongly narrowed, 
tricarinate, at the front much narrower than one of the eyes, occiput 
behind the eyes exposed; eyes higher than the dorsum of pronotum; 
frontal costa rather roundly compresso-elevated between the antenne, 
not at all sinuate; apical articles of maxillary palpi oval; the 
antenne inserted almost between the inferior border of the eyes. 
Pronotum often lightly rugulose, depressed, little ascendant behind 
the anterior margin, subdeplanate between the shoulders and bearing 
* One of the common species of Tetrigine in Borneo is Paratettia 
contractus of Bolivar. This species is considered a Tetrix here, and 
will be so treated further on under that heading.
