much redder than the first joint, with a conspicuous process at the 

 dorsal apex and with a complete circlet of tiny black bristles which 

 becomes slightly longer on the underside ; third joint about twice as 

 long as two basal joints together, darker with the basal annulation 

 reddish yellow to reddish black, about three times as long as its 

 broadest part, and large dorsal hump near the base crowned with some 

 tiny black bristles ; basal annulation of" the third joint very slightly 

 shorter than the style-like portion and about one and a four-fifth times 

 as long as its broadest part, usually darker apically ; the style-like 

 portion gradually narrowed to a sharp point, with the apical annulation 

 about twice as long as the shortest second annulation, bearing one or 

 two inconspicuous pubescence on each annulation but on the apical 

 one somewhat conspicuous. Eyes bare, when seen from above the 

 frontal margin about four-fifth as long as the hind margin which is 

 nearly straight and forms a upper angle about 100 with the frontal 

 margin, and the outer margin moderately rounded ; in profile oval, 

 deeper than the length, with the frontal, lower, and hind angles round- 

 ed and with the upper angle smaller though rounded ; when seen from 

 the front about as wide as the depth, the frontal angle about 145, 

 the lower angle about no' and rounded, the upper angle about 50 

 and the outer angle evenly rounded, and the facial margin about as 

 long as the frontal margin ; in death deep purplish black with a green- 

 ish shimmer in a certain light, without any spots or bands. 



Thorax about as long as wide, moderately rounded. Dorsum 

 greyish brown or greyish black, with five faint stripes of which the 

 middle one is narrowest and more greyish but extends only a little 

 after the suture, and the next two are slightly wider, reaching the 

 posterior margin, and somewhat broadened and obscured at the suture 

 after which they become very inconspicuously oblique inwardly, while 

 a lateral pair is very faint, broadest, and extends from the humeri to 

 the postalar calli passing on the praealar calli, and after the suture 

 they rapidly become narrow and innerside of this part there is an
