Genus XXVI.— CERACLEA, Leach. 



Aidennw slender, very much longer than the wings, not denticulated within, 

 the basal joint rather short and stout, the terminal ones extremely slender: 

 palpi very pilose; maxillary with the two basal joints short, the 3rd 

 elongate, 4th shorter than the 3rd, 5th slender, slightly pilose : head small, 

 densely hairy in front : eyes large, subglobose : thorax stout : wings trans- 

 parent ; anterior elongate, narrow, rounded at the apex, nervures very 

 distinct, the 3rd and 5th bifid at the tip ; posterior obtusely triangular ; 

 cilia of all short: abdomen short, rather slender in the males, stout and 

 obtuse in the females : legs shortish ; tihiw all furnished with a pair of 

 spurs at the apex only ; intermediate and posterior pair somewhat bristly 

 beneath. 

 The antennae of Ceraclea are remarkably long and slender, which 



character, united to the transparency of the wings, their conspicuous 



nervures, the two short basal joints of their palpi, robust thorax, &c.. 



serve to distinguish the genus from Leptocerus, in which genus tlie
