Mesoiiotal prsescutum with tliree dark browuish-hlack 

 stripes, tlie median stripe entire ; scutal lobes dark ; legs 

 yellow, the femora and tibiae narrowly tipped with black ; 

 wiuj^s yellowisl), a narrow dark brown seam along the cord ; 

 abdominal sternites witli a continuous median brownish- 

 black stripe. 



Male. — Length 15-2 mm. ; wing 12*4 mm. ; abdomen 

 alone, 11*5 mm. 



Female. — Length 17'5 mm. ; wing 12*2 nun. 



Generally similar to the other species of the genus herein 

 described, differing as follows : — 



Mesonotal prpescutum with three dark brownish-black 

 stripes, the median stripe entire or only shallowly bifid 

 anteriorly ; scutal lobes dark brown ; scutellum yellowish 

 testaceons ; postnotura pale yellowish. iMesopleura largely 

 dark coloured. Legs dull yellow, the tips of the femora and 

 tibiee narrowly (1 mm.) black; tarsi brownish yellow, the 

 distal segments dark brown. Wings dull yellow, the costal 

 region more suffused ; conspicuons brown clouds at the 

 origin of Rs and the tip of i?2 ; a narrow dark brown seam 

 across the wing at the cord, beginning at the stigma, com- 

 pletely encircling cell \st .V^ ; a brown cloud at the fork of 

 Mij^2 5 ill the alloty[)c the base of the wing and vein M are 

 likewise seamed with broAvn. Venation : Rs strongly angn- 

 lated at origin, at the bend "iih an interrupted cross-vein 

 to M as in the genotype and many other species of this 

 genus ; JR2+3 very short, only about two-thirds the length of 

 i'-m or about equal to m ; inner end of cell 1st M^ pi'O- 

 longed and pointed ; cell M^ a little longer than its petiole ; 

 basal d(>flection of 6'wi slight iy or far beyond mid-length of 

 cell \st Mo, in the type and p iratype being at nearly three- 

 fourths the length. In the alloty])e, cell 1st M., is smaller 

 and its inner end is not so prolonged. 



Abdominal st( rnites with the median brownish-black band 

 almost continuous from the base of the abdomen to the 

 eighth sternite, scarcely (if at all) interruj)ted at the incisures ; 

 eighth sternite black basally, the distal half dull yellow.
