striated, and in the colour of the coxae and trochanters of the 

 legs, which in the others are black. From Pseudagenia ariel, 

 Cameron, it differs in not having the mandibles rugose, in the 

 shape of the protborax, and in the colour of the legs and wings. 



Paeagekia, gen. nov. 

 Allied to Agenia, Schiodte, and Pseudagenia, Kobl ; differs in 

 tbe body being more slender and the legs longer in proportion, 

 in tbe coxae and femora of the legs being thickened as in tbe 

 genus Macromeris, particularly so in the male, which has, further, 

 the coxae of the intermediate legs produced in front into large, 

 remarkably prominent cone-shaped tubercles. In both sexes 

 the joints of the anterior tarsi are extremely attenuated at base. 

 The neuration of the wings is similar to that of Pseudagenia, the 

 species of which genus the type and only known species of 

 Paragenia resembles in its breeding-habits, making cone-shaped 

 nests of clay and filling them with spiders.

I have a long series of this species, which I have compared care- 

 fully with the types in the British Museum. Smith placed it under 

 Lepeletier's genus Macromeris, probably because of the swollen 

 coxae and femora in the male ; but it cannot be classed under 

 that genus, as the fore wing has tbe radial cell acuminate, not 

 rounded, at apex, the tibiae and tarsi are spinose, and there is no 

 lateral tubercle on the thorax in front of the intermediate coxae.
