Lasioplera tertia, sp. n. 



Gall. — A potato-shaped smooth swelling on the twigs of 

 some asteroid composite. The galls are of various shapes, 

 sometimes subglobular, 11x9 millim., or elongated, 17 millim. 

 long, constricted in the middle ; they are always quite broad 

 and more or less irregular. 



Imago. — Similar to the two described above. The abdo- 

 men has distinct white bands, more or less interrupted in the 

 middle line. Costa black, with a distinct but small white 

 spot, margin of wing black. Legs more or less pallid, grey 

 or brown.
