Anal cell of fore wings present; propodeum divided.., . Perreyiinas 

 Anal cell of fore wings wanting; propodeum not divided 



Philomastiginse 



SUBFAMILY PERREYIIN^. 

 The only genus known to occur here is Perreyia Brulle. 



SUBFAMILY PHILOMASTIGIN^. 



Founded for Philomastix Froggart, but may include other genera.

The proepisternum is not divided. For the time being this family 

 may be divided into two subfamilies by the characters used by Konow 

 and other authors. 



TABLE TO THE SUBFAMILIES. 



Fore wings with an intercostal vein.., Arginse. 



Fore wings without an intercostal vein Sterictiphorinse 



FAMILY BLASTICOMID.E. 

 Founded for Blasticoma filiceti Klug. 



FAMILY DIPRIONID.E. 



The same as Lophijrides Konow (Genera Insectorum, fas. 29, 1905, 

 p. 41). 



FAMILY TENTHREDINID.E. 



Prepectus wanting (in some species of Allantus there is an ob- 

 scure lip, but in these the proepisternum meets 

 ventrally) 



Prepectus present (in Strongylogasterini narrow, but in these 



the proepisternum does not meet ventrally ) 6 



1. Proepisternum ventrally very large and meeting in the 



middle where it is usually tfuncate; prosternum usu- 

 ally triangular; mandibles long, strongly falcate; 



metapostnotum large; elongate species 



Proepisternum ventrally small and widely separated; 

 prosternum T-shaped; mandibles short, not strongly 

 falcate; metapostnotum short; robust species... 4 



2. Basal vein joining the costa at or very near the origin of 



the cubitus (in some species in this group the basal 

 vein is strongly curved and is close to costa without 

 joining it so superficially the basal vein appears to join 



the costa removed from the cubitus) Allantinne 



Basal vein joining the costa much basad of the origin of 



the cubitus... 3
