CRIOTETTIX Bolivar.

Included tricarinatus, nexuosus, horrei, nigellus, saginatus, miliaris, 

 haeri, subulatus, vidali, perminutus, rugosus, insidiosus, pidcher, pnllus, 

 and clavitarsis Bolivar, nodulosus Stal, hrevis and emarginatus Haan 

 and bispinosus Dalman. Of these the last is the oldest and probably 

 the best known and may with justice be considered the type. 



Criotettix bispinosus (Dalman). 



1818. Acrydium hispinosum Dalman, Ivongl. Vetenskaps Academiens 

 Handlingar, 1S18, p. 77. [East India.]

 August-September, 1901. (A. C. Harrison, Jr., and Dr. H. M. Hiller.) 

 [A. N. S. Phila.] One female. 



This species has a very extensive range, the territory covered includ- 

 ing Burma, Sumatra, Java, Borneo and China. The only previous 

 Sumatran record was from Batang Singalang, mentioned by Haan. 



Criotettix bispinosus japonicus (Haan). 



1839-44. A[cridium] (Tetrix) bispinosutn var. Japonica Haan, Bijdragen 

 Kennis Orthoptera in Verhandl. Natuurl. Geschied., p. 169. 



Loo Choo Islands, Japan. (Through Y. Hirase.) Nine males, eight 

 females. [A. N. S. Phila., and Hebard Coll.] 



These specimens represent a well-marked geographic race of bispi- 

 nosus, characterized by the more apparent linear rugosities on the pro- 

 notum and the slightly broader fastigium. 



Section Metrodorse. 

 SYSTOLEDERUS Bolivar. 

 1887. Sj/stolederus Bolivar, Ann. Soc. Entom. Belg., XXXI, pp. 194, 234, 

 Included ang usticeps a,nd uncinatus Sia\ , cephcdiciis Haan, and ophthal- 

 micus, haani and languidus Bolivar; of which haani is well figured and 

 may be considered the type. 



Systolederus cephalicus (Haan). 



1839-44. A[cridium] (Tetrix) cephcdicum Haan, Bijdragen Kennis Orthoptera, 

 in Verhandl. Natuurl. Geschied., p. 169. [Batang Singalang, Sumatra.] 



Batu Sangkar, Tanah Datar, Padangsche Bovenland, Sumatra. 

 August-September, 1901. (A. C. Harrison, Jr., and Dr. H. M. Hiller.) 

 [A, N. S. Phila.] Three males, four females. 



These specimens appear to represent this species which is known 

 only from Haan's brief description. Bolivar, having never seen the 

 species, was unable to add any information to the original description. 

 The possession of a pair of more or less apparent post-humeral spots of 

 velvety black is shared by all the specimens, which are, however, 

 somewhat smaller than Haan's measurements.
