New or Little-knoivn Exotic Tipulidae. 57 



equal to r--m; 111 beyond r only a little shorter than the basal 

 deflection of Cul; R'l before r about twice this cross- vein; cell 

 Ml lacking; basal deflection of Cul at about one-third the length 

 of cell 1st M2 ; Cu2 a little more than one^half of the deflection of 

 Cul. 



Hab. Brazil (Ex the Winthem Collection). 



Erioeera nigrochalybea, sp. n. 



General coloration black with steel-blue reflexions; vertex fiery 

 orange ; legs black, the femoral bases yellow ; wuigs dark brown ; a 

 conspicuous light yellow cross- band before the cord; base of cell E 

 and most of cell 1st A pale; abdomen brownish black, the hj^popy- 

 gium and base of the second sternite brighter. 



Male. — Length 12-3 mm. ; wing 12 mm. 



Rostrum and palpi brown. Antennae short, dark brown, the 

 scapal segments brighter on their ventral faces. Vertex fiery orange, 

 the remainder of the head orange ; vertical tubercle relatively high, 

 notched anteriorly. 



Mesonotum entirely black with conspicuous steel-blue reflexions. 

 Pleura concolorous, very sparsely pruinose. Halteres dark brovv'n 

 throughout. Legs with the coxae and trochanters brownish 

 black ; only a single leg (anterior) remams ; this is dark brown with 

 the basal quarter obscure j^ellow. Wings dark brown ; a conspicuous 

 arcuated light yellow band before the cord, beyond cell 1st 312 

 swinging distad and includmg the basal half of cell Cul ; this band 

 extends fi'om cell 1st Rl across the wing, reaching the posterior 

 margin as a mere point at vein Cii2 ; cells R3 and R5 are entirely 

 dark, cell 1st M2 similar except the extreme proximal angle; cell 

 R is pale basally, this colour narrowly connected with the yellow 

 band at the cord by a pale streak caudad of the sector ; cell 1st A 

 is largely pale, only the distal end narrowly darkened; veins dark 

 brown, paler in the yellow areas. Venation : Scl ends just beyond 

 the fork of Rs, Sc2 rather close to the tip of Scl, the latter alone 

 shorter than the deflection of J?4 -f 5 ; r on R2 about its own length 

 beyond the fork ot R2 -\- 3; basal deflection of Cul immediately 

 beyond the fork of M. 



Abdomen dark brownish black with steel-blue reflexions; second 

 sternite obscure yellow on basal half. Male hypopygium small, 

 obscure reddish bro^vn. 



The paratype is very similar to the tyjDc, but the femoral bases 

 are not brightened.
