only by a ilcep ami narrow U-shaped notch. Basal pleural 

 appeniiage elongate, the tips very strongly recurved to appear 

 like a shepherd's crook; distal pleural appendages two in 

 Muniber, one a Hatteneil bhiek blade that bears on its lateral 

 angle a long, divergent, black spine (thuiub) ; the second 

 apical appendage is a slender pale rod that is feebly bent 

 near niid-leugth. Gonapophyses appearing as two parallel 

 blades that suggest in appearance a bird, the beak being the 

 terminal black S|)ine, the dorsal margin or back being micro- 

 scopically toothed.

Ampfiineurus olagensis, sp. n. 



Male. — Length 3'8-4- mm. ; wing 6-6*5 mm. 



Generally similar to A. harrisi, differing as follows : — 



Average size of body a little smaller. Anteuuje of male 

 considerably longer than the body. Basal detlcction of Cu^ 

 before the fork of M, ihe distance a little greater than the 

 basal detlection of 37i_2 5 cell Mz petiolate, the petiole only 

 a little shorter than the basal detlectiou of Cu^. Malehypo- 

 pygium with the ninth tergite somewhat as in A. I'ecurvans, 

 consisting of two straight rods that are feebly divergent ; 

 these rods are relatively very long and slender, the tips sub- 

 acute ; space separating the rods U-shaped. Pleurites pro- 

 duced into elongate, setiterous, digitiform lobes as iu the 

 genus. Basal pleural appendage a long, slender, acicular 

 rod, very gently curved, tapering gradually to the acute 

 blackened apex ; apical pleural appendages two, one slender, 

 rod-like, weakly sinuous, the second a large tiattened blade 

 that bears the usual lateral divergent spine (thumb), and, 

 in addition, a smaller, more obtuse spine near the mid- 

 distance to the apex, lying in the angle of the thumb; apex 

 of this blade acute, blackened. Gonapuphyscs a little ^horter 

 than the penis-guard, tapering to the acute blackened tips, 

 guard relatively slender, straight, ou either side produced 

 into a somewhat flaring wing.
