Batjan Island, Celebes, 106 the present insect is found to differ in its 

 smaller size, black and strikingly contrasted face and conspicuous 

 ocelli. 



Were punctipennis not already known to be subject to great 

 color variation, the striking facial coloration of the present insect 

 would lead us to suppose it to be specifically distinct. 



Type: cf ; Obi Island, Moluccas. [Hebard Collection, Type no. 



850.] 



Agrees closely with Griffini's description of the synonymic subsp. 

 dempwolffi, differing as follows. Head with occiput, caudal half 

 of genae, vertex to median ocellus and palpi light ochraceous-buff ; 

 ocelli washed with old rose; face, cephalic half of genae, mandibles 

 and dorsal portion of clypeus shining blackish brown; 107 ventral 

 portion of clypeus buffy, labrum etruscan red. Antennae buffy, 

 washed with old rose proximad. Pronotum and limbs buffy, washed 

 with old rose. Tegmina transparent, light ochraceous-buff, immac- 

 ulate. Wings transparent, light ochraceous-buff, with four or five 

 rows of rounded and sharply delimited spots of mummy brown in 

 radiate field and an interrupted, short, submarginal line of the same 

 color. These markings surround the cross- veinlets and reappear as 

 a few scattered flecks in the anterior field. 



Length of body 23.7, greatest width of fastigium of vertex 1.1, 

 length of pronotum 4.9, length of tegmen 18.3, greatest width of 

 tegmen 5.1, length of cephalic femur 7, length of caudal femur 

 12.2, length of longest cephalic tibial spine 1.9 mm. 



The type is unique. 



Gryllacris annulicornis new species. Plate XXII, figure 6. 



Though running in Griffini's key for the Bornean species of 

 Gryllacris m to section A, the narrow vertex and strikingly marked 

 pronotum and limbs show closer agreement with the Bornean 

 G. maculipes subspecies irregularis Griffini, than with any other 

 described forms 



Though irregularis is apparently subject to considerable color 

 variation, we believe that comparison will show annulicornis to 

 be even more widely distinct than we can at present determine 

 from the description of that subspecies. 



The sharply and thickly annulate antennae, and ovipositor, 

 which tapers evenly to its apex, constitute striking characters for 

 the present species. 



106 Later very fully diagnosed by Griffini as G. punctipennis subspecies demp- 

 wolffi, which name that author has placed in synonymy under punctipennis after 

 imination of Walker's type (Boll. Lab. Zool. R. Scuola Sup. d'Agr. Portici, 

 III, p. 218, (1909).)
