and below, except on the narrow under margin bare, but its apex 

 with a few longer black pubescence ; second joint small and about a 

 half as long as the basal joint, with a rather broad above apical process, 

 covered with numerous tiny black pubescence which becomes scarce 

 towards the base and disappears on the inner upper narrow margin ; 

 third joint longer than the twice of the basal two joints together, the 

 basal annulation very broad and about one and a half times as long 

 as its broadest part at where it bears a rather long and large dorsal 

 tooth (just before the middle) crowned with two or three tiny black 

 bristles, and its lower margin moderately bent beneath at before the 

 middle ; style-like portion about a half as long as the basal broad an- 

 nulation, with the basal three annulations somewhat transverse of which 

 the middle one is shortest, while the top annulation is rather short 

 conical with the blunt point and is not very much longer than the 

 preceding one, each annulation bearing one or two very inconspicuous 

 fine pubescence about the top. Eyes bare, with the facets all equal, 

 in death deep greenish black" ; when seen from above the hind margin 

 nearly straight and about one and a half times as long as the frontal 

 margin, the top angle about 105", and the frontal angle about 8o° but 

 the outer margin not much convex ; in profile somewhat regular oval, 

 narrowed above, apparently deeper than long ; when seen from in 

 front slightly wider than deep, the facial margin very slightly convex 

 and slightly shorter than the frontal margin, the frontal angle about 

 1 3 5 °, and the top angle about 100°. 



Thcrax rounded, very slightly longer than width, blackish, ob- 

 scured by a pale yellowish grey tomentum, and covered with numerous 

 very short depressed yellowish pubescence intermixed with abundant 

 still short erect black hairs which are replaced by numerous longer 

 pale soft hairs on the anterior vertical part, with three somewhat dis- 

 tinct narrow greyish yellow median stripes and a pair of similar but 

 much broader and more inperfect lateral stripes, of which the middle 

 one is narrowest and only extending beyond the suture and the next
