NOTASPIS BIPILTS. 357 



serrated spine (the lamellar hair) directed straight 

 forward. The rostral hairs, which are set on slight 

 protuberances, are large and strong. Pseudo-stigmatic 

 organs long, straight, strongly serrated spines, directed 

 almost transversely, but slightly inclined forward. The 

 interlamellar hairs are enormous, being great, serrated, 

 straight spines directed forward, outward, and upward, 

 almost reaching the point of the rostrum. The tecto- 

 pedal ridges are very strong and the cavities to receive 

 the first pair of legs very large. 



Legs long and thin ; the femora of the first two 

 pairs are very fine towards the proximal extremity, 

 swelling suddenly a little before the centre ; the hind 

 femora have blades. The tibia3 of all the legs have 

 much the same formation. There are tactile hairs on 

 all the legs, those on the first pair being very long. 

 There is a remarkably long, strong, straight, serrated 

 spine on the coxa of each leg of the third pair near the 

 proximal end, at the outer corner : this spine usually 

 stands more or less parallel to the pseudo-stigmatic 

 organ, and it is from these two spines on each side 

 that the name is given. There are two or three pairs 

 of short, curved, serrated spines on each tarsus and 

 one pair on each other joint ; all the tarsi are densely 

 clothed with long fine hairs. 



Abdomen circular and arched ; it bears two pairs of 

 large, straight, serrated spines, one pair on the hind 

 margin and the other pair a little within the margin ; 

 four shorter hairs on the ventral surface just show from 

 the dorsal aspect. Genital and anal plates small and 

 far apart. 



Nymph. 



This very handsome nymph was, as above stated, 

 known to Koch, but was treated by him as a distinct 

 species and called Murcia acuminata. 



Colour translucent white passing into light tints 

 of yellow and grey ; some specimens are wholly
