• NEMATUS. 189 



brownish coloured, and the trochanters black. Thom- 

 son, however, distinctly says of Brullaei, " alis basin 

 versus pleurumque subfumatas." 



Brischke describes neither the larvae of tener, Brullaei, 

 nor tristis. For our species I propose to retain the name 

 of tristis, because (supposing the two are identical) the 

 imago of Brullsei was not described by Dahlbom ; and 

 Zaddach's description and name have priority over 

 Thomson's. 



Nbmatus (Vol. II, p. 44). 



Konow has split up the old genus Nematus into ten. 

 He includes in the tribe Nematina, besides these, 

 Gladius and its sub -gen era, TricJw campus and Prio- 

 phorus, Euura, Dineura, Hemichroa, and Gamponiscus. 

 His arrangement is as follows : 



1. Lanceolate cellule in the middle widely constricted. 2. 

 Lanceolate cellule petiolate. 6. 



2. The second and third cubital cellules each receiving a recurrent 



nervure. 3. 



The second cubital cellule receiving both recurrent nervures. 5. 



3. The third to fifth, sometimes also the sixth and seventh in the <$, 



having a longer or shorter process; in the 5 compressed, and 



terminating at the apex in a short process. Cladius, 111. 



Antennal joints without process at the apex. 4. 



4. The third antennal joint at the base constricted underneath in the 



<$, with a short, stumpy fork ; in the ? with a sharp edge. 



Trichocampus, Htg. 

 Antennae without any peculiarity. Priophorus, Latr. 



5. With one radial cellule. Gamponiscus Newm. 

 With two radial cellules. Hemichroa, Steph. 



6. With two radial cellules, the intercostal transverse nervure anas- 



tomosing behind the transverse discoidal. Dineura, Dbm. 



With one radial cellule ; the intercostal transverse nervure received 



before the transverse discoidal. 7. 



7. The apex of the clypeus more or less deeply emarginate or 



incised. 8. 



Clypeus transverse. 17. 



8. The second transverse cubital nervure absent. Euura, Newm. 

 The fore-wings with four cubital cellules. 9. 



9. The claws at the apex bifid. 10. 

 The claws before the apex with a small tooth, not parallel with 



it. 15.
