DESCRIPTIONS OF .\MY BPXCIE& 1 1 5 



width, with the -apical side a little Bhorter than the outer side, 

 and twice as long as the internal side which becomes basal, and 

 meets the apical side almost at right angles. The penultimate 

 joint of all the tarsi is cordate and somewhat lobed, and the first 

 joint of the hind tarsi is nearly twice as long a- the others united. 

 AUopoda may be distinguished from Anaspia and its allies, 

 which have similar maxillary palpi and hind tarsi, by the I:;-; 

 joint of the labial palpi being transverse and secoriform — the 

 antenna) not being thickened externally — by the anterior tro- 

 chantin being distinct, and by the different form of the hind coxae, 

 which do not conform to the ventral surface, but are raised from it.
