No. 64] DIPTERA OF CONNECTICUT : TAXONOMY 291 



General coloration obscure yellow, praescutal stripes brown or 

 grayish brown. Antennae obscure yellow or brownish yellow, weakly 

 bicolorous. Male hypopygium with median tergal spines (Fig, 32, K) 

 long and slender, needle-like. Posterior lobe of inner dististyle long 

 and slender, almost touching the posterior basal appendage. Kods 

 of eighth sternite (Fig. 32, J) slender, parallel-sided, separated by 

 a wide U-shaped notch. 



The more southern iimhrosa Lw. has the median tergal spines 

 shorter and broader, not needle-like ; posterior lobe of inner dististyle 

 relativel}^ short and blunt. Tlie exact limits of distribution of the 

 two species have not been accurately determined, i. L. 18-20 mm.; 

 w. 20-22 mm. ; antenna, 7-7.5 mm. ? . L. 26-28 mm. ; w. 20-23 mm.
