TO NEW GUINEA IN 1904 AND 1905. PART 11. 41 



widened at the apex ; the keels bordering it are broad, rounded; 

 at the apex they roundly diverge. Metanotum with a band of 

 longitudinal striae near the middle. First abdominal segment 

 closely longitudinally striated ; the area on the 2"'^' segment 

 is long, becomes gradually narrowed to a sharp point which 

 reaches to the base of the apical fifth of the segment ; at 

 the broad base it is smooth, the rest is closely, finely longi- 

 tudinally striated ; the part bordering it is more roughly and 

 irregularly striated ; the suturiform articulation is deep, closely 

 crenulated ; shortly beyond it is a furrow, which curves 

 roundly backwards to a rounded point, it is crenulated, except 

 at the sides ; there is a similar, crenulated furrow at the base 

 of the 4"^'^ segment, with a broadly curved one on eitherside. 

 The 2"*^ cubital cellule is much narrowed in front, owiuo: to 

 the steep, oblique slope of the 1-^ transverse cubital nervure; 

 the l^'f abscissa of the radius is longer than usual; it is more 

 than half the length of the 2"'' ; the 3''<^ is shorter than the 

 basal 2 united ; the recurrent nervure is received in the 

 l''^ cubital cellule, clearly distant from the transverse cubital ; 

 the anal nervure issues distinctly above the lower part of the 

 nervure, not interstitial with it.

Head cubital, largely developed behind the eyes. Metanotum 

 with an areola, lanceolate above, on its apical half. Second 

 abdominal segment with a narrow, but distinct, semicircular 

 furrow ; the segments smooth. Radial cellule long, reaching 

 to the apex of the wing ; the radius issues from very shortly 

 behind the middle of the stigma, which is long and narrow. 

 The third abscissa of the radius is more than twice the length 

 of Uie basal two united; the 1^^ about one fourth of the 

 length of the 2'^'^; the recurrent nervure interstitial. The 2"'^
