I make a new name for our species without hairs on the metanotum, 

 not knowing whether it will include the typical Agcnia or not. The 

 type of Melanaporus Ashm. is a two-celled form of P. argcnteus or 

 a close ally. 



Table of Subfamilies. 



1. Claws of hind tarsi bent at right angle; antennse situate considerably above 



the clypeus ; labrum exserted for its entire length ; metanotum at base 



bilobed, the spiracle in a depression opening forward Ceropalin<E. 



Claws not bent at right angle; spiracles not in such a depression 2 



2. Metanotum flat above, not bilobed at base, the spiracles situate nearly twice 



their length from the anterior margin of metanotum ; labrum exserted for 



its entire length; no spines under last joint of hind tdirsi. . . .Notocyphina. 



The spiracles not much more than their length from the anterior margin of 



metanotum ; labrum never more than partially exserted 3 



3. A transverse furrow on the second ventral segment (absent in some males) ; 



in the fore-wings the second discoidal cell at base is right-angled, and with- 

 out a distinct pocket Pepsince. 



No such furrow on the second ventral segment ; in fore-wings the second 

 discoidal cell has a small pocket at base ; the hind tibiae never serrate, 



always more or less irregularly spined Psainmocharina:. 



The Ceropalinas has, in our fauna, but one genus — Ceropales. 



The Notocyphinse include two genera : 

 I. With a distinct malar space between eyes and base of mandibles ; male 

 antennje crenulate below ; labrum broader than long ; hind tibiae 



spined AUocyphonyx. 



Without a malar space : male antennae not crenulate ; hind tibis barely 

 spined ; labrum longer than broad Notocyphus. 



The Pepsinae include several genera, some of which may be divided. 



1. Hind tibiae without spines or only very weak ones, never serrate; in hind- 



wings the transverse median vein ends before the cubitus ; male often with- 

 out ventral furrow, last tarsal joint without spines beneath or few very 



weak ones (Ageniellini) 2 



Hind tibiae more or less serrately spined, if (J') nearly smooth, then the 

 transverse median vein of hind-wings is not before cubitus (Pepsini) . . . 3 



2. Metanotum with erect hair above ; . . .Pseudagetiia. 



Metanotum without erect hair above. 



AgenieUa n. gen. (type, Agenia accepta Cr.). 



3. Wings rudimentary Myrmecosalius. 



Wings well developed 4 



4. Last joint of hind tarsus without spines beneath ; in the hind-wings the 



transverse median vein ends before or at the cubitus Cryptocheiliis.
