P. pavida is rare in Denmark, I know seven specimens, six males 

 and a female; two specimens are without particular locality, the 

 others from Jutland at Sønderborg and Sottrupskov (Wiistnei), and 

 from Bornholm at Sandvig (Weis) and at Hammeren (the author); 

 the dates are ^Z, — ^^/g. One of our specimens is bred from an undeter- 

 mined lepidopterous larva, another from Dryohota protea (Weis), 

 not earlier known as host for it. It is otherwise known from a great 

 number of Heterocera and also from Allantus cingillum. 



Geographical distribution: — Europe; it is not known north 

 of Denmark, whereas the nearly related pumicata Meig. occurs in 

 Sweden.
