SCHIZOCERA GEMINATA.

tions in the mode of insertion of the antennae that I 

 am unable to look upon this as a generic character. 

 Further, the same species formed the type of Schizo- 

 cera and Cyphona, so that the latter name is scarcely 

 admissible. If then 8. geminata is to be separated 

 from Schizocera the name of Sericocera, Brulle, should 

 be used, as that does not seem to differ from Cyphona 

 as defined by Thomson, except in having the antennae 

 longer, and with a longer and more silky pubescence. 

 Our two British species belong to Cyphona. The 

 epistoma is indistinctly keeled. There is no cross ner- 

 vure in the costal cellule ; the basal nervure is received 

 considerably in front of the first cubital cellule ; the 

 first transverse cubital nervure is often very faint ; the 

 third cellule short, not much, if any, broader than long, 

 dilated at the apex ; the second recurrent nervure is 

 received quite close to, or joined to the second trans- 

 verse cubital. The abdominal segments are, at the 

 base, depressed a little, so that the apex of the seg- 

 ment in front is higher.
