The two specimens (Nos. 87, 88) from which the d scription 

 was drawn are .somewhat discoloured by spirit, but that is not a 

 very important injury. P. soJcotranus is considerably smaller than 

 the other species of the genus, and is probably pecuHar to the 

 island. 



Two females (Nos. 83, 84). Upon the second segment of 

 both specimens there is a curious round pale hard knob, so large 

 that it has caused a space in the elytra where they cover it when at 

 rest. I have omitted it from the description as it seems to be 

 a foreign body, possibly a fungus. 



There is also an immature Grasshopper (No. 85), possibly to be 

 referred to the genus Acridium. 



GrRTLLODEA. 



Landkeya, sp. n. ? 



A male Cricket (No. 86) of the genus Landreva Walk, seems 

 to be new, but is not sufficiently good for description. It is small, 

 testaceous, with truncate elytra and no wings. The tympanum is 

 only visible on the exterior side of the anterior tibia (subgenus 

 Ectolandreva, Sauss.); the posterior tibite are armed with five 

 spines on each margin above, and four terminal spines.
