others. Epistoiue setose. Proboscis prominent, rather longer 

 than the palpi. Palpi four-jointed; first joint short, about 

 as broad as it is long; second joint long and greatly swollen, 

 broadest in tlie middle ; third joint rather shorter, cylindrical, 

 much narrower than the first two joints; fourth joint slender, 

 cylindrical, longer than any of the others. Anteimae shorter 

 than the thorax, 2 + 15 jointed ; first joint of scapus cu- 

 puliform, twice as long and twice as broad as the second, 

 wliich is also cupuliforna ; joints of flagellum cylindrical, 

 length about three times the breadth, covered with a dense 

 pubescence, central portion of each joint with stout seta^ 

 Thorax strongly arched, its surface covered with a thin pu- 

 bescence ; lateral margins, with stout setaB. Scutellum small, 

 fringed with long setae. Metathorax acclivous. Abdomen 

 rather slender, broadened rather posteriorly, slightly pu- 

 bescent, seven-segmented. Forceps of male large, almost 

 flabelliform, not chelate, covered with setae. Legs long and 

 slender ; coxae stouter than the femora, setiferous at the tip 

 and on the outer surface ; femora very slender, slightly pubes- 

 cent ; tibiae long and slender, in fore-leg shorter than tarsus, 

 in intermediate leg about as long as tarsus, and in posterior 

 leg nearly twice the leneth of tarsus, fore and intermediate 

 tibiae with practically no spines, but posterior tibiae with two 

 ranges ; spurs rather short ; tarsi pubescent, with a few 

 small prickles. Wings about as long as abdomen, rather 

 scaly near posterior margin, and hairy near the apex, remark- 

 ably rounded at the apical end, and cuneiformly narrowed 

 at the base. Auxiliary vein rather more than one-third the 

 length of the wing, disappearing just before reaching the 

 margin ; first longitudinal more than two-thirds the length 

 of the wing ; inner marginal cell one-third the length of the 

 wing ; petiole of second longitudinal less than the length from 

 apex of inner marginal cell to the commencement of the third 

 longitudinal ; anterior branch of second longitudinal long, 

 arcuated, running very gradually into costa; posterior branch 

 very strongly arcuated, joining costa almost at the apex ; costa 

 slightly extended beyond point of junction; fork of third 

 longitudinal slightly beyond fork of second ; fourth longitu- 

 dinal only slightly arcuated ; fifth longitudinal more strongly 

 arcuated, reaching margin some distance beyond apex of inner 

 marginal cell ; sixth longitudinal slender, long, but incomplete. 

 I have at present only received a specimen of one species 

 belonging to this genus.
