Walker described this as with three lateral spines, but Kirby, who 

 had the type before him for examination, says that this was an opti- 

 cal illusion. Kirby placed the saginatus of Bolivar as a synonym of 

 this species, in which he was apparently justified, the only tangible 

 difference noticeable between these Javan specimens and ones deter- 

 mined by Hebard from India being size, those from Java having a 

 pronotal length in the female of 16 mm. while in the Indian specimens 

 this is 17 mm. in the male and 20 to 21 mm. in the females. Bolivar 

 gives 18 mm. as the pronotal length of the female of saginatus, being 

 intermediate between the specimens noted above. 



ACANTHALOBUS, species 



One male from Buitenzorg in March. A very heavy form appar- 

 ently allied to rohustus Hancock but having the posterior metatarsus 

 decidedly longer than the apical segment of the tarsus, in which 

 respect it agrees with the macropterous miliarius of BoUvar, It is 

 perhaps undescribed, but it is deemed unwise to erect new species in 

 this difficult group from unique specimens. 



ACANTHALOBUS, species 



Two males of a smaller species than the above are in the collection 

 from Pelaboean Ratoe without date. 



SYSTOLODERUS PARVUS? Hancocl( 



Systoloderus parvus? Hancock, Trans. Ent. Soc. Lond., 1907, p. 227. 



Three females of what is probably this species are in the collection, 

 two from Mount Salak on May 25, and one from Pelaboean Ratoe 

 without date. Tlie isolated description of this species, which makes 

 no mention of certain important characters, makes certain determi- 

 nation impossible. The present specimens have the posterior ocelli 

 located at a point barely if at all below the middle of the eyes, not 

 on a plane with the antero-ventral border of the eyes as stated in 

 the description of parvus, thus indicating specific distinctness. 



MAZARREDIA CELEBICA Bolivar 



Mazarredia celehica Bolivar, Ann. Soc. Ent. Belg., vol. .31, 1887, pp. 186, 238, 241.

 Ratoe without date. 



EUPARATETTIX PERSONATUS Bolivar

Six males and five females as follows: Buitenzorg, three females j 

 Mount Salak, six males and one female; Bantar Gebang, one male;

This is a smaller species than E. variahilis as represented by Javan 

 specimens determined by Hebard in the National Museum. The
