neic genera and species of Tentlir edinidcE.. 143 



cellule ; the marginal nervurc is joined to the third sub- 

 maro'inal, and is a little cni'ved. The first submarginal is 

 not half the size of the second, which is of nearly the same 

 length as the third, but the latter is very much wider at 

 its apex than the second, which is of nearly equal width 

 throughout ; the fourth is longer than the third, and is 

 much widened at the apex. The first recurrent nervure 

 is received a little in front of the middle of the second 

 cellule, the second is joined to the second submarginal 

 nervure. The lanceolate cellule is petiolate. There is 

 one medial cellule in the posterior wings ; at the apex is 

 a small curved appendicular cellule. 



In the alar neuration this genus does not differ much 

 from Blennocamjia, but otherwise is readily separated by 

 the pilose antennre thickened in the middle, by the large 

 projecting coxfB (which are as large as in Macrophya), 

 by the long legs, with the very long basal tarsal joint, and 

 perhaps, also, in the appendicular cellule in the posterior 

 wings, although we have some indications of this in some 

 species of Blennocampa. The pronotum, also, is longer 

 and more developed, and the lobes of the mesonotum are 

 better marked. 



Zarca apicalis, sp. n. 



Pilose, smooth, shining, luteous ; the antenna3, head, 

 tibice, tarsi and apex of abdomen, black. Wings blackish, 

 iridescent ; the nervures, costa and stigma, black, the last 

 two parts being very pilose ; in the second submarginal 

 cellule is a horny point. The two anterior tibite are 

 sordid luteous, the mandibles are piceous, and the palpi 

 pale testaceous. The tegulas are luteous. 



Length 4^ lines; alar exp. 12g lines. 



Hab. — Brazil (Swainson). 



Incalia, gen. nov. 



Antennas of the length of the mesothorax, thickish, but 

 scarcely thickened towards the apex; densely covered Avith 

 a long pile ; 7-jointed, the 1st joint is cylindrical, and more 

 than double the length of the 2nd, and nearly a fourth 

 shorter than the 3rd, which is the longest ; the 4tli is 

 about the length of the 1 st ; the three last are closely 

 joined together, the 7th being a very little longer than 

 the others, and conical. The head is rather narrow, trun- 

 cated behind; the eyes projecting, reaching to near the
