It falls into Bolivar’s subgenus Trwzalis, sensu stricto, and into the group of 
croced, Bol., with brilliantly coloured wings and carinated sternum.

Q. Parva, testacea. Pronotum altius quam longius, antice paullo pro- 
ductum ; lobis deflexis margine posteriore recto, margine anteriore sinuato ; 
meso- et meta-nota perspicue liberans. Pedes antici et tibie tarsique inter- 
medii infuscati ; tibize postice haud lobate.

This species is considerably smaller than P. hippiscus. In the shape of 
the pronotum it approaches rather to an undescribed species in the Brunner 
Collection, but differs in its smaller size and paler colour. 
Phaulotypus, gen. nov. 
2.  Pronotum caput obtegens, compressum, elevatum, antice et postice 
acuminatum, postice valde productum, crista margine superiore equaliter 
rotundata, venis nullis instructum, totum granulatum.  Elytra et ale nulle. 
Caput in modum Choretypi formatum. Femora antica et intermedia com- 
pressa nec dilatata ; femora postica valde compressa et dilatata, crista superiori 
denticulata, lobis genicularibus acuminatis. Tibi postice: curvate, haud 
lobate, calcaribus terminalibus margine exteriore minimis, calcare interno 
Maximo: tarsorum segmentum primum minutissime crenulatum. Frons 
granulata. 4 ignotus. ; 
This new genus can be easily distinguished from the other genera of the 
group Choretyy. The shape of the pronotum, the absence of the lobes on 
the posterior tibiz, and the absence of organs of flight distinguish it at once.

I have great pleasure in dedicating this curious little novelty to Mr. 
Ogilvie-Grant, who collected Orthoptera so assiduously in Sokotra.
