338 MK. W. F. KIEBY — A EEVISION OF 



Anatva anomala. (Plate LIII. fig. 9 ; appendages, Plate LVII. fig. 7.) 



Long. Corp. 32-34 millim. ; exp. al. 47-50 millim. ; long. pter. 3 millim. 



Male. — Head yellow, frontal tubercle and middle of the clypeus blue, tips of the 

 mandibles and back of the head above black, and below reddish towards the base; 

 thorax pale greenish blue with irregular blackish or reddish markings above, and to a 

 less extent on the sides ; under surface yellow ; coxae with a black spot at the tips above ; 

 femora yellow, black above from a little beyond the base; tibiae and tarsi black; 

 abdomen black, the base banded and spotted with dull pale blue (buflf in less mature 

 examples), which is continued on the sides of the third segment beyond the carina as 

 a broad dark stripe reaching nearly to the extremity ; this is followed by buff stripes at 

 the sides of the bases of segments 4 and 5, a much shorter and broader one on the sides 

 of segment 6 in the middle, and, lastly, a round spot on each side of segment 7, nearly 

 meeting above. Anal appendages yellow, the upper ones tipped with black. Wings 

 very clear hyaline ; pterostigma dark reddish brown between black nervures. 



Female. — Yellow, the thorax a little varied with reddish ; abdomen yellow at the 

 base, and reddish brown beyond the carina of the third segment, spotted with yellow 

 as in the male ; femora, tibise, and tarsi as in the male ; pterostigma yellowish brown. 



Hah. Brazil. 



In one specimen the neuration is very irregular, the last antenodal nervure on the 

 left front wing, on the upper costal space, is nearly continuous with the last nervure in 

 the lower costal space ; but on the right wing the last two antenodals are entirely 

 discontinuous, an anomaly of which I have seen but one other instance. 



Tyriobapta toekida. (Plate LIV. figs. 5, 6.) 



Long. Corp. 30-35 millim. ; exp. al. 52-64 millim. ; long. pter. 3-4 millim. 



Male (mature). — Head black, clypeus above and frontal tubercle violet-blue, sides 

 and base of labium yellow ; thorax and base of abdomen dull reddish brown, the former 

 with a transverse black band before the wings and black stripes on the sutures of the 

 pleura ; abdomen otherwise black, with a row of dull blue spots on the sides of seg- 

 ments 3-8 above. Legs testaceous brown nearly to the end of the femora and black 

 beyond. Wings hyaline, pterostigma dark brown ; hind Avings with a large purplish- 

 brown blotch at the base, with green and purple reflexions, broadest at the anal angle, 

 where it covers rather more than one fourth of the wing. 



Male (immature). — Thorax and abdo!nen testaceous brown, the black markings are 

 much more distinct, the transverse band in front of the thorax is connected with and 

 preceded by a black stripe on the median line ; the three stripes on the pleura are 

 unconnected with this, but are nearly connected with each other below ; the abdomen 

 is black, with the base, and a row of spots on the sides of segments 3-8, testaceous 

 brown ; the blotch on the hind wings is light brown, and is confined to the neighbour- 

 hood of the anal angle.
