thickened, apically and dorsally produced very cap-like over the second 

 joint, and bearing very short inconspicuous black bristles above and a 

 few short black hairs beneath ; second joint very small and short, about 

 one-thirds as long as the first joint, and the upper part usually con- 

 cealed beneath the cap-like process of the first joint, pointed cap-like 

 over the base of the third joint, and with a fine sharp dorsal process 

 at the top, and bearing a terminal, circlet of short black bristles which 

 are most distinct on the underside ; third joint with the very, broad 

 basal annulation and with the very slender style, the former at the 

 broadest part about five-sixth as wide as its length, and the latter 

 about as long as the broad basal annulation ; the dorsal hump obvious* 

 ly angled, but after which the dorsal margin of this annulation is very 

 slightly concave, and with one or two minute inconspicuous black 

 pubescence on the top ; the style-like portion with three basal annula- 

 tions almost quadrate, but the terminal annulation very long and slender 

 and very slightly shorter than the remaining ones together, this long 

 annulation sometimes being paler and rarely with the top somewhat 

 yellowish and not sharply pointed.- Eyes large, in life purplish green 

 at the upper half and somewhat dull metallic green at the lower half, 

 the dividing line straight, narrow and purplish brown, in profile slightly 

 deeper than long, oval, with somewhat straight upper, moderately 

 convex frontal, and strongly downwardly curved lower, margins ; when 

 seen from in front slightly deeper than the width, the frontal and lower 

 angles about 130°, the latter with rounded margin, the upper angle 

 about ioo°, and the outer angle evenly rounded. 



Thorax subquadrate with rounded angles, slightly longer than 

 the width, greyish black with five faint pale grey stripes of which the 

 middle one is narrowest and is hardly reaching the posterior margin, 

 and the outer two stripes are much distinct, extending below to the 

 posterior-inner ends of the postalar calli and gradually contracting from 

 the suture to the posterior margin but not conspicuously fused together, 

 while the lateral stripes are broadest and extend from the humeri to
