 Schmarotzerinsekten. [The artificial Infestation of Individuals of

 [Received 16th December 1916.] 



Specimens of the Tachinid, Prosopodes fugax, Rond., obtained from 

 Hyponomeuta euonymellus, were placed on larvae of the vine-moths, 

 Clysia ambigueUa, Hb., and Polychrosis botrana, SchifE., on which 

 development was completed. Though Dibrachys boucheanus and 

 Agrypon flaveolatum, which were also bred from H. euonymellus, are 

 both parasites of these moths, oviposition on the larvae was not 

 effected experimentally. The suppression of hedges of Euonymus m. 

 vine-growing districts would appear to be inadvisable in the light of 

 these experiments.

The various stages of Psylliodes affinis, Payk., are described. The 

 young potato plants are not nmch injured by this beetle or its larvae, 

 but the foliage of older plants suffers great damage from the feeding of 

 the adult. P. affinis also lives on Lycium, Hyoscyamus, Atropa and 

 various species of Solanum.

While Parasetigena segregata, Rond., attaches its eggs to the host 

 larvae, Panzeria rudis brings forth its larv^ae alive and these settle on 

 fir needles, which are the usual food of the larvae of Panolis flammea 

 (piniperda), the normal host of this Tachinid. The larvae of the nun 

 moth, Lymantria monacha, are only attacked when no other suitable 

 host is available.
