This species is readily distinguished from validispinus, 
by the smaller stature, being narrower between the 
shoulders, in the more coarsely granulate pronotum, the 
more slender thoracic spines, the less extended and 
straighter pronotum, and the black elytra and wings.

This species occurs in the Philippines, and was described 
by Bolivar under the caption Criotettiz, It was in- 
advertently omitted from my list of the species of Criotettix 
in my article in Genera Insectorum (48me Fasc. Orthoptera, 
Subfam. Tetrigine, p. 28, 1906), but it is referred to 
there in a foot-note. Attention was called to the species 
as belonging to a new subgenus. I find it falls naturally 
under the new genus Bolotettiz above described. 
4, It is quite likely that Criotettix nigellus (Bolivar, Ann. 
Soc. Ent. Belg., p. 225, xxxi, 1887) belongs here also. It 
is from Gaboon (Bolivar). 
Genus OCYTETTIX, nov. 
Recalling Charagotettix, to which it bears a near resemblance, 
Body strongly rugose ; vertex wide, transverse, imperfectly carinate 
forward, on each side bearing a small compresso-acute carina, in- 
wardly interrupted, fossulate on each side of the small median 
carina; eyes small; face moderately oblique, strongly sinuate ; 
frontal costa roundly compresso-produced between the antenna, 
viewed in front sulcate little above the posterior ocelli, below the 
rami moderately subparallel to the median ocellus ; posterior ocelli 
placed between the lower third of the eyes; antenne inserted dis- 
tinctly before the eyes; maxillary palpi little compresso-ampliate 
apically. Pronotum anteriorly truncate, middle of the anterior 
margin often excavate, posteriorly acuminate, the apex spinose, often 
upturned and not extended backward beyond the knees of the hind 
femora ; dorsum strongly depressed, often unigibbose forward and 
transversely fossulate between the shoulders, backwards often 
quadrinodulose ; the humeral angles produced outwards laterally 
and strongly carinate, the lateral margins just before and behind 
the shoulders strongly elevated ; the lateral carine profoundly com- 
presso-sinuate ; median carina strongly compresso-gibbose in front 
of the shoulders, depressed and indistinct behind the anterior 
margin, anterior prozonal carine strongly expressed, fossulate be- 
tween them, lateral scapular area at the sides wide ; lateral lobes at
