Subfamily EUMASTACINAB 



ERUCIUS JAVANUS Burr 



Erucius javanus Burr, An. Soc. Espan., vol. 28, 1899, pp. 89, 109, 110. 



One mated pair, Tjibodas, Mount Gede, A pril 20, a female nymph 

 from same locality and an adult male from Buitenzorg in March. 



Subfamily AcRroiNAE. 



ACRIDA TURRITA Linnaeus 



Gryllus {Acrida) turrita Linnaeus, Syst. Nat., 10 ed., 1758, p. 427. 



One adult male, Mount, Salak, May 15; one large female nymph 

 from Buitenzorg in March and fourteen adult females from Mount 

 Salak, Depok, and Buitenzorg on various dates. '1 he male and five 

 of the females are brown, the others green. The lanceolate supra- 

 anal plate of the immature forms of this species is indeed a remark- 

 able development. 



PHLAEOBA FUMOSA Serville 



Opsomala fumosa Serville, Ins. Orth., 1839, p. 593. 



Five males, 20 females and one female nymph from Buitenzorg, 

 Mount Salak, and Pelaboean Katoe on various dates from March to 

 June. This series showed very little variation in size or color. 



AIOLOPUS, species 



An adult male from Buitenzorg in March is referred to the genus 

 Aiolopus. It does not appear to be the A. tamulus of Fabricius and 

 may perhaps represent an undescribed form. 



Subfamily Oedipodinae 



HETEROPTERNIS OBSCURELLA Blanchard 



Oedipoda obscurella Blanchard Voy. Pole Sud., Zool., vol. 4, 1853, p. 375. 



One male and sixteen females, the male from Buitenzorg and all 

 the females from Mount Salak. The wings of these specimens are 

 more or less yellowish basally, though this is very surely a variable 

 character as some of apparently the same species from the Philip- 

 pines have the wings basally roseate instead of yellowish. The lateral 

 lobes of the pronotum vary a little in the posterior margin, which 

 ranges from almost straight to noticeably concave; the posterior- 

 inferior angle is rounded, in no way subproduced and acute as de- 

 scribed in the works of Saussure for the allied splendens of Walker 

 {=pyrr7hOscelis Stal). 



GASTRIMARGUS TRANSVERSUS Thunberg 



Gryllus transversus Thunberg, Mem. Acad. Petersb., vol. 5, 1815, p 233. 



Five males, three females, and three female nymphs from Mount 

 Salak, two females from Depok and one female from Buitenzorg. 

 These specimens are essentially like ones of G. marmoratus Thunberg 

 in the National Museum collection apparently determined by Saus-
