Sp. Trypeta Arctii MEIG., DE GEEK, Ins. vi. Tab. 2, figs. 614, PANZER, 

 Deutschl. Ins., Heft 103, Tab. 22 ; yellow-green body with yellow-brown 

 feet ; wings with four transverse brown stripes, which at the external or 

 anterior margin of the wings are united two and two. The larva lives in 

 the flowers and seeds of Arctium Lappa and other Synantherece j each peri- 

 carp holds only a single larva, which is placed in it head downwards. 

 Other species live in excrescences (like those of gall-nuts) on thistles. The 

 species of this genus are very numerous. The head is broad ; the abdomen 

 has five segments, and ends in the female in an ovipositor extended to 

 a point. The wings during life are mostly in a quivering motion and 

 erect ; they are usually spotted or striped with darker bands.
