1912] Alexander — New Nearctic Tipulidae (Diptera) 169 



Head: palpi dark, blackish, rostrum much paler brown; antennae short in both 

 sexes; scapal segments dark above, reddish-yellow underneath; flagellar segments 

 black. Front, vertex and occiput black with a grey pruinosity, most distinct behind 

 the eyes. 



Thorax : mesonotal prsescutum light yellowish-brown with a dark brown stripe 

 on either side of the paler median vitta, these stripes broadest in front, narrower 

 behind, ending just before the suture; a shorter, curved, lateral stripe on the lateral 

 edge of the sclerite, beginning just behind the pseudo-suture, continuing to the 

 transverse suture; scutum, scutellum and post-notum blackish, scantily grey 

 pruinose; pleurse unicolorous greyish-black. Halteres, base of stem, pale, yellow; 

 remainder of stem, and the knob, dark brown. 



Legs: coxae light brown; trochanters and basal three-fourths of the femora, 

 light brownish-yellow; apical fourth of the femora, brown; in the fore-legs, the 

 apical half of the femur is brown; tibia light brown, the tip black; tarsi brown. 



Wings: veins dark brown; membrane rather uniformly tinged with light brown; 

 stigma small, delimited externally by the radial cross-vein; extreme tip of the 

 wing rather darker. Venation (See fig. 7) : cross- vein r near the tip of Ri, situated 

 far before the fork of R2-1.3; R2 much shorter than R2+3; cell Mi absent; basal deflec- 

 tion of Cui slightly before the fork of M. 



Abdomen shiny black, including the large hypopygium; in the 9 , the valves of 

 the ovipositor are likewise black.

Types in author's collection. 



Nearest related to E. fuliginosa O. S. (East. U. S.), from which 

 it is readily distinguished by the lack of a grey bloom on the thorax, 

 the shiny jet black abdomen and genitalia, etc. In normal indi- 

 viduals oifultonensis, cross-vein r is far before the fork of R2+3 (See 

 fig. 7). In rare instances, however, the cross- vein is much nearer 

 to the fork though never quite at it. Specimens which I refer 

 to fuliginosa, provisionally, show a venation similar to that des- 

 cribed for the species (See fig. 8); the coloration is very dark, 

 however, and comparison with the type may prove them to be 

 novelties. E. fultonensis differs from E. gibbosa Doane^ (Mich.) 

 in the same ve national peculiarity. 



Eriocera cinerea sp. no v. 



Cell Ml absent; color of the thorax light grey; stripes on the mesothoracic 

 prsescutum indistinct; cross- vein r far beyond the fork of R2+3.
