Tribe (sub-family] . TENTHREDINA. 

 Sub-tribes. 



Tenthredinides. Antennae 9-jointed. Wings with two radial and four 

 cubital cellules, the second and third receiving each a recurrent 

 nervure. Lanceolate cellule subcontracted, or with a perpendicular, 

 and more rarely with an oblique cross nervure. Basal nervure received 

 at a distance from the cubital. Hind wings with two middle cellules. 

 Mandibles acute, large, with two or three large teeth, besides the large 

 apical one. Calcaria as long as half of the metatarsus. Larvae ejecting 

 a black or brownish liquid from the mouth. 



Dolerides. Antennae 9-jointed. Wings with two radial and three 

 cubital cellules, the second cubital the largest, and receiving two 

 recurrent nervures. Basal nervure received at a distance from cubital. 

 Lanceolate cellule with an oblique cross nervure. Hind wings with 

 i;wo median cellules. 



Selandriades. Antennae 7- to 15-jointed. Wings with two radial 

 and three or four cubital cellules. Lanceolate cellule petiolate or open, 

 with an oblique cross nervure, or contracted. Basal nervure joined to 

 the cubital. Hind wings rarely with two median cellules, often with 

 one only or none. Spurs short. Mandibles weak, short, without 

 distinct teeth on the sides. 



Sub-tribe TENTHREDINIDES. 



The Tenthredinides have longish, narrow bodies, the abdomen being 

 longer than the head and thorax, somewhat depressed above, and, as a 

 rule, broadest in the middle. The antennae are either long and fili- 

 form or short and subfusiform at the apex ; in the latter case the third 

 joint is much longer than the fourth. The head is much broader than 

 long, concave behind, and to a less extent in front. The eyes are large 

 and projecting, seldom reaching to the base of the mandibles. The 

 clypeus is large, and generally deeply incised; labrum orbicular. 

 Mandibles large, curved, and toothed. Legs long, coxae of normal size, 

 or so large as to reach the fourth abdominal segment. Spurs at least 

 as long as half of the metatarsus, and generally longer than that. 

 Hinder tarsi longer than the tibiae. Patellae very well developed; 

 claws large, bifid. 



Wings with two radial and four cubital cellules. Costal cellule 

 distinct, with a cross nervure. Radial nervure curved, usually received 

 towards the middle of the third cubital cellule. The second and third
