Sp. Trypeta Arctii Mrtc., De Guur, Ins, vi. Tab. 2, figs. 6—14, 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 Arctiwm Lappa and other Synantheree ; 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.
