260 Professor Williston on the 



men reddish-yellow ; each segment with a large, subtriangular, 

 black spot, the base directed posteriorly and the apex reaching 

 nearly or quite to the anterior maigin ; last segment wholly black. 

 Legs yellow, the tarsi brownish ; front metatarsi longer than the 

 tibiee ; middle tarsi a third longer than the tibiae ; hind tarsi of 

 about the same length as the tibiae. Wings tinged with brownish; 

 an indistinct band across the outer part, and a similar spot at the 

 base of the anterior forked cell. 



Four specimens. 



Manota^ n. g. 



Head flattened, placed rather high as regards the thorax ; face 

 and front broad, the antennas situated high up, directed upwards 

 and forwards ; composed of sixteen joints closely united, the basal 

 joints a little differentiated from those of the flagellum. Three 

 ocelli of nearly equal size, situated near the vertex, in a gently 

 curved line, the lateral ones about as far from the inner borders of 

 the eyes as from the middle one. Palpi composed of three joints, 

 elongate, the terminal joint slender and directed angularly back- 

 wards. Dorsum of thorax moderately convex ; scutellum with short 

 bristles. Abdomen slender, flattened cylindrical. Femora stout, 

 flattened ; front and middle tibiae with one, the hind tibiae with 

 two spurs ; hind tibiae and metatarsi with a row of short bristles 

 on the outer side ; all the tibiae without long bristles ; coxae elongate. 

 Wings longer than the abdomen ; auxiliary vein rudimentary ; the 

 first vein terminates before the middle of the wing ; third vein 

 not furcate ; fourth vein wanting, save the distal portion of its 

 branches ; fifth vein furcate near the basal portion of the wing ; 

 the costa extends a considerable distance beyond the termination 

 of the third vein. 



As in the following genus, the proximal portion of the 

 two outer veins is so wholly obliterated that it is impos- 

 sible to trace them. 



1. Manota defecta, n. sp. (PI. VIII., fig. 14.)

 middle of the abdomen if bent backward. Face and front 

 brownish-yellow. Mesonotum reddish or yellowish-brown, finely 

 white pubescent. Pleurae a little lighter coloured. Coxae and 

 femora light yellow, the middle coxae near the upper part with a
