FUNGUS GNATS OF NORTH AMERICA. 285 



V'ar. a. A number of specimens resemble both the above 

 and the following species {L. liiieola) in most particulars, dif- 

 fering from the former and resembling the latter in the pleural 

 marking; but differ from the latter in having hind coxae and 

 femora as in the former. In some specimens the head is 

 marked as in the former w^hile others are marked as in the 

 latter. The forceps limb of a Wyoming specimen is show^n in 

 figure 165. The last section of Ri is at least as long as the R-M 

 crossvein (Fig. 199). The preapical wing band is broad except 

 in the Carolina specimen. San ford Univ. (J.M.A.) ; Marin Co.
