384. Mr. F. W. Edwards on a remarkable 
Ninth tergite not distinguishable from the tenth, parallel- 
sided, with a broad V-shaped apical emargination, which is 
finely hairy. Side-pieces completely united with the ninth 
sternite, practically bare, without lobes or modifications of 
any sort. Claspers simple, rather broad at the base, narrower 
apically, but with rounded tips; on flexor surface with 
numerous short curved hairs. Adceagus a simple, strongly 
chitinised tube, somewhat broadened at its base. 
Legs slender, absolutely bare except for a fine, close, erect 
pubescence on the outer two-thirds of the tibie. Coxe all 
small, scarcely longer than the trochanters, the hind pair 
somewhat stouter than the others. Femora nearly 
cylindrical, all about equal in length, the front pair a little

Front (/), middle (m), and hind (hf) legs, x 80; 
body in side-view, x 14. 
stouter than the others. Front tibize about one-half longer 
than the femora, very slender on the basal two-fifths, then 
rather slightly and evenly enlarged to nearly twice the 
diameter. First segment of front tarsi cylindrical, nearly 
half as long as the tibia, and almost as long as the three 
following segments together, the last four segments about 
equal in length. Middle tibize one-third longer than the 
femora, nearly cylindrical, the apical third only considerably 
enlarged on the flexor surface, extensor surface somewhat 
concave ; tarsal segments bearing the same proportions to 
the tibia as in the front legs, and therefore shorter than the 
front tarsi. Hind tibize resembling the front ones. First
