lanceolate cellule has an oblique cross nervure ; the third 

 joint of the antennae (which are short) is distinctly longer 

 than the fourth ; the patellae are not developed. 



Allomorpha. 



This genus was created by me for a Chinese species 

 {Trans. Ent. Sac, i8j6, p. 46 j). It belongs probably to 

 the Tenthredinides rather than to the Selandriades, but 

 actually is intermediate between the two. The transverse 

 basal nervure is received before the base of the radial, not 

 close to or joined to it, as in the Selandriades, with which 

 it agrees in having the calcaria short, not reaching near 

 to the middle of the metatarsus; the lanceolate cellule 

 has an oblique cross nervure ; there is only one middle 

 cellule in the hinder wings ; the clypeus is deeply incise'd ; 

 the mandibles are long, sharply pointed, and end in one 

 long tooth ; the eyes are large, almost parallel, and reach 

 close to, but do not touch, the base of the mandibles. 

 The antennse do not taper towards the apex, and are 

 long and slender. The claws are bifid. The antennae 

 appear to have three colours in all the species. 



Allomorpha varicornis, sp. nov. 



Fiilva; antennis nigris, basitestaceis, apice albis; tnaciilis 

 mesonoti mesosternoque mgris ; alis hyalinis, stigmate fusco, 

 basi testaceo. $ . 



Long. II mm. 



Antennae not much longer than the abdomen, the 

 basal three joints testaceous, the fourth, fifth, and the 

 greater part of the sixth, black ; the rest white. On the 

 head the ocellar region, the front broadly in the middle
