h AN UNDESCRIBED SAPROMYZID (DIPTERA). 



By J. R. Malloch, F.E.S., Urbana, 111. 



On August 30 and September i of this year I found single- 

 specimens of an apparently undescribed sapromyzid on a wound 

 on an elm tree from which sap was exuding. At the first glance 

 the species appeared to belong to the Drosophilidse, but a closer 

 examination showed that Avhile there are certain similarities the 

 species does not really belong to that family, and has more affini- 

 ties with the Sapromyzidse. I have during the present year been 

 paying a considerable amount of attention to the early stages of 

 Diptera, and it has been more the exception than the rule that I 

 have discovered undescribed species, although in the case of the 

 minute forms several have been found of which the present is one. 



The characters which appear to associate this genus with the 

 subfamily Lonchaeinse of the family Sapromyzidse are as follows : 

 Orbits with one reclinate bristle ; postverticals divergent ; arista 

 plumose; third antennal joint slightly longer than broad; face 

 slightly concave ; vibrissae undifferentiated ; mesonotum with two 

 pairs of dorsocentrals, scutelluni slightly convex, rounded in 

 outline ; abdomen short and broad ; auxiliary vein weak ; anal 

 cell present ; preapical tibial bristle absent. 



Phorticoides, gen. nov. 



Generic characters : Auxiliary vein very short, ending at two-fifths from 

 base of first vein, abruptly bent towards costa near apex, the angulated 

 portion indistinct and not extending to costal vein; costa ending at apex 

 of third vein ; anal cell present, the cross vein closing it apically indis- 

 tinct; inner and outer cross veins present, not approximated; anal vein 

 indistinct, not extending to wing margin. 



Type of genus : Phorticoides flinti, sp. n.
