210 Phoridae. 



The species of Aphiochaeta occur especially on leaves of bushes 

 and low herbage, generally in woods in more or less humid and shaded 

 piaces; they run quickly around on the leaves, and when disturbed 

 they fly only for a short distance; some species are also seen on flowers, 

 especially of umbellifers, and here often in sunshine. Like the other 

 Phorids they have a curious way of running, which makes them easily 

 recognizable; when they are taken by sweeping with the net in herbage, 

 and the net then is filled with small flies,- the species of Aphiochaeta 

 are at once recognized in the net only by their movements, and this 

 is fortunate for else they woiild be much more difficult to coUect; 

 I have been deceived only by certain small Borborids and by the 

 species of Drapetis. It is rare that a single species predominates in a 

 locality, thoiigh this may happen, f. inst. Woodi, atripes, tiimida, 

 latifrons and perhaps a few others I have found so, otherwise by 

 sweeping in a locality a relatively large number of species in propor- 

 tion to the niimber of specimens is generally to be had ; as an example ! 

 I shall note that from a short collecting in a small locality I once } 

 brought home 40 specimens including no less than 27 species, and of j 

 snch instances I could enumerate many; the given example is from the 

 summer 1921, which was very dry, and Phorids in no way common. 

 The species are most numerous in autumn. Some few species may 

 sometimes be seen swarming, I have f. inst. taken latifrons occurring i 

 in small swarms around the leaves of a Corylus, the swarms consisted 

 only of males, and I have seen tumida swarming round the end of , 

 branches of Acer, and here both sexes were present. ' 



Of the genus about 230 species are hitherto known from Europe, 

 but no doubt a number of species will be detected hereafter; of the 

 about 230 European species 154 are at present known from Denmark 

 two of which are here described as new. 



As regards the following table I must premise some remarks. 

 As most of the European species may be expected to occur in Denmark 

 I have endeavoured to include all these species in the table, but 

 numbering only the species hitherto found here;^ some species, 



Since my manuscript was finished Schmitz has (Entom. Ber. Nederl. Ent. Ver, 

 VI, 1921, 1) described three new species: styloprocta, irregularifrons and offus- 

 cata; the first, only known in the female sex, has four scutellar bristles, meso- 

 pleura bristly, and abdomen ends with an ovipositor; the other two, of which 

 only the male is known, have bare mesopleura, but are difficult to locate, 

 as they have both costa and costal cilia rather midway between short and 

 long; irregularifrons has the frons about as high as broad, shining, balteres
