of palpi not being characteristically swollen as in that genus, and 

 being decidedly shorter than remaining portion of palpus, instead 

 of vice versa. Face with a large, thick beak, pointed at tip, 

 thickened portion more or less distinctly wrinkled transversely. 

 Dorsum of thorax, at least in J of genotype, devoid of the small 

 or minute, rounded, wart-like tubercles, which, though varying 

 greatly in different species in size and number, are characteristic 

 of the majority of Pantophthalmidae, though apparently not 

 present in all, at any rate in both sexes. Hind legs with a large 

 subf emoral spine ; terminal spine on hind femora very small, at 

 least in genotype.

Although at the time of describing this striking species the 

 author considered that there were no real grounds for separating 

 it from RItaphiorhynchus {c/. Austen, L cit. vol. xvi. p. 130), it 

 seems advisable on further consideration to reverse this view, 

 especially when regard is paid to the important palpal characters 

 to which attention is di-awn in the generic diagnosis above. 



The type of A. rothschildi — a <S from Buenavista, Bolivia 

 (,/. Sleinhach) — is in the Tring Museum, and the British Museum 

 (Natural History) possesses a paratype of the same sex from 

 Ecuador {Backley). Duiing the fourteen years that have elapsed 

 sinc^ the species was described, no further specimens of it have
