36 Platypezidae. 



P. boletina is very rare in Denmark, we have only one specimen, 

 a male, from earlier time, without particular locality; the above 

 description of the female is drawn from a Swedish specimen, sent 

 from Zetterstedt to Stæger. Zetterstedt records it from V? to '^*/g. 



Geographical distribution: — Northern and middle Europa 

 down into France and northern Italy; towards the north to middle 

 Sweden, and in Finland. 



Remarks: Our specimen is bred from the pupa, and the same 

 is the case with two specimens from Zetterstedt; the puparium 

 shows no filaments at the sides, and is upon the whole quite similar 

 to the puparium of injiimata figured by de Meijere; one of them 

 even shows remnants of a cocoon, as far as I see. Accordingly it is 

 obvious, tliat the larva mentioned by v. Roser and Westwood as 

 boletina cannot belong to this species, but a mistake in the determin- 

 ation must have taken place; perhaps the species has been tnodesta.
