344 Phoridae. 



Bogø south of Sealand, Ærø (Th. Mortensen, the author), on Lolland 

 at Strandby and in Kældskov (L. Jørgensen) and on Læsø (Th. Mor- 

 tensen); the dates of capture are ^^U — ^7? in 1917 to 1921. The spec- 

 imens from Lolland came on ^'/a and ^^U from a material of shells 

 of Helix taken by Mr. Jørgensen on '/s and ^Vs and probably bred 

 from the snails, and Dr. Mortensen took it in some numbers at Hille- 

 rød on putrid Planorhis corneus on ^"/s; it seems thus to choose, or 

 at all events to prefer snails for depositing the eggs. 



Geographical distribution: — Northern and middle Europe, 

 towards the north to middle Sweden and Finland, and it is recorded 

 down into Tunis; it is also recorded from North America. 



Remarks: As seen from the description the species varies to some 

 degree; the frons is sometimes strongly, sometimes much less shining, 

 and it may be rather high, but going down to being about quadratic; 

 the inner bristles of lower row may be not little varying in position, 

 being placed more or less low down, and also being near to the eye- 

 margin or more remote from it, placed in the middle between the eye- 

 margin and the upper supraantennal ; fmally the colour of legs and 

 palpi and the length of costa vary. Four of my specimens, a male 

 and three females (from Ærø, Strandby and Læsø) belong to the 

 darkest form, with the posterior legs black and dark palpi, at the 

 same time they have a high and strongly shining frons and the bristles 

 on hind tibiæ moderate. All my other specimens have brown or yellow- 

 ish brown posterior legs, yellow palpi, a not much shining frons which 

 is often relatively broad, and strong hind tibial bristles; they cannot 

 belong to the following species as they have equal supraantennals 

 with the upper pair widely distant and long bristles on the palpi. As 

 Wood doubted the specific identity of the male and female which he 

 first described, thus I think it just possible that these specimens 

 might belong to a separate species, intermediate between minor and 

 angustifrons, but at present I cannot decide it. 



I have seen Zetterstedt's types, there are two specimens, one, 

 labelled "Ostrogh.", is headless, the other, labelled "Lund" has a 

 moderately shining frons and thus seems to belong to the mentioned 

 variety which has the frons less shining.
