third abdominal tergite. — Wood says for pygmaea 1 more than 

 double 2 + 3; as shown by my measurements 1 is at most double 

 2+3, but often shorter. 



A. pijginaea is not common in Denmark; Dyrehaven (the author), 

 Holte (Th. Mortensen); it seems to occur during the whole year, my 

 dates run from ^/i to "''/12 in 1917 to 1921; only one specimen I have 

 taken in the open on ^^/s, all the others were taken by Dr. Mortensen 

 on the windows in his villa near the wood; the specimens taken 

 on ^^/i2 were brought in with a Christmas tree, taken from the wood 

 the day before. 



Geographical distribution: — The species seems widely distrib- 

 uted; all Europe, towards the nortli to southern Sweden; further 

 recorded from Formosa and from the Canaries and also occurring in 

 North America.
