AKT. 3 ORTHOPTEROID INSECTS FROM JAVA CAUDELL 25 



sure; the scutellum of the vertex in all the Javan specimens are, how- 

 ever, less concave and with a very distinct raised longitudinal carina 

 extending its entire length, while in the two specimens of marmoratus 

 examined this scutellum is more concave and has a very slight median 

 carina, and that not continuous. These characters, while constant in 

 the Javan series here recorded, are evidently subject to more or less 

 variation, as two males and a female of G. africanus Saussure, as 

 determined by Uvarov and now before me, show decided variation in 

 this respect. 



TRILOPHIDIA CRISTELLA Stal 



Oedipoda cristeUa Stal, Eug. Resa, Orth., 1860, p. 344. 



One male and four females, Buitenzorg; one female, Batavia; one 

 female, Pelaboean Ratoe. 



TRILOPHIDIA ANNULATA Thunberg 



Gryllus annulate Thunberg, Mem. Acad. Petersb., vol. 5, 1815, p. 234. 



One male, three females, Buitenzorg; one female. Mount Salak; 

 one male, Megamendg Mountains, (4,800 feet altitude) ; one male, 

 Pelaboean Ratoe. 



Supei-ficially this species appears rather similar to cristella but is 

 somewhat larger. Annulata also has the median carina of the pro- 

 notum more profoundly bisected than in cristella, though it is rather 

 deeply cleft in both species. The most salient morphological char- 

 acter separating these two species is found on the prozona, where in 

 annulata is seen on each side of the disk near the anterior margin a 

 well elevated tubercle while in cristella there is but a slight diagonal 



carina at this point. 



Subfamily Pyrgomorphinae 



AULARCHES PUNCTATUS Drnry 



Gryllus (Locysta) punctatus Drury, 111. Exot. Ent., vol. 2, 1773, pi. 41, fig. 4. 



One male, Buitenzorg in June, and one female, Mount Salak on 

 May 4. 



TAGASTA MARGINELLA Thunberg 



Tagasta marginella Thunberg, Mem. Acad. Petersb., vol. 5, 1816, p. 265. 



One adult female, without locality label but with an altitude label 

 reading 3,000 feet; also a female nymph from Bantar Gebang. Allow- 

 ing for sexual differences this adult specimen agrees very well with the 

 description of the male as given by Stal in 1873.^ 



ATRACTOMORPHA PSITTACINA DeHaan 



Acridium (Truxalis) psittacina DeHaan, Temminck, Verhandel., Orth., 1842, 

 p. 146. 

 Three adult males and a female nymph from Pelaboean Ratoe and 

 three males from Buitenzorg.
