t,-m.; second s.m. long, narrowed about half above. Legs 

 slightly brownish, anterior knees with a yellow spot ; spurs 

 red. Abdomen broad, shining, segments 2 to 4 each with a 

 broadly interrupted basal cream-coloured band, the lower 

 margin of which on each side is convex ; apical segments 

 with a good deal of black hair ; ventral segments with thin 

 fringes of long hair. Maxillary palpi with six subequal 

 joints, the basal ones the longest; labial palpi with one long 

 joint and three short ones, which together do not exceed the 

 long ones. 



cJ. — More slender ; pale markings light lemon-yellow, as 

 follows : — face below antennae (including supraclypeal band 

 and dog-ear marks), rapidly narrowing extensions of lateral 

 uiarks about halfway up sides of front, interrupted band on 

 prothorax above, anterior and middle knees, anterior tibia3 in 

 front, greater part of anterior tarsi, a rather vague mark at 

 base of middle tarsi, and basal bands on abdominal segments 

 2 to 6, at most slightly interrupted in middle. The apex of 

 abdomen has a long tuft of fuscous hairs, curled upward, 

 appearing pallid when seen from beneath. On the venter, 

 subapically, is a broad strap-shaped lobe, broadest in middle, 

 emarginate at end, and "With plumose hairs arranged along 

 the sides as a fringe, the apex also hairy. This lobe arises 

 from the apical margin of tlie fifth segment. 



Type from Santiago, Chile ; two ? s received years ago 

 from Prof. E. S. Gr. Titus as C. suhmetallicum, Spinola, 

 which is a larger insect with greenish abdomen, belonging to 

 the genus Liopceum. 



There are also before me 2 ? and 1 c? of (7. reedi collected 

 by E. C. Keed in Chile (U.S. Nat. Museum). I expected to 

 find this identical with one of the species of Spinola, Friese, 

 or Vachal ; but it is evidently distinct from all. There is a 

 superficial resemblance to the paler-haired form of C. hirsuU 

 ulum, Spin.
