tooth moderately concave ; the style-like portion of the third joint 

 comparatively short and stout, gradually narrowed to a point where 

 there are one or two tiny but conspicuous black pubescence, the an- 

 n ulations lengthened one after another, and the tip one wholly twice as 

 long as basal one, and on each annulation there are two or three 

 minute pubescence near the apex. Eyes large, bare from pubescence, 

 with all the facets practically equal in size, in death deep purplish 

 black with strong metallic ruster ; in profile about one and a half times 

 as deep as long, irregularly oval, the frontal margin being longest and 

 slightly curved anteriorly, and the remaining margin being almost evenly 

 rounded semicircularly ; when seen from in front deeper than wide, 

 the frontal angle about 130, the lower angle about 110 with rounded 

 angle, the upper angle about 99, and the outer angle evenly rounded. 

 Thorax short but longer than the width, blackish, slightly 

 shining though it covered with greyish totnentum, with three yellowish 

 grey median stripes and broad similar coloured lateral stripes, these 

 stripes being very faint and of which the middle one is narrowest and 

 hardly extends behind the suture, and the next pair is nearly reaching 

 the hind margin of the thorax and is slightly inwardly oblique after 

 the suture, while the lateral pairs is very broad, occupying whole the 

 sides, but obscure behind the praealar calli ; these longitudinal 

 bands whitish grey on the anterior border, and the rest somewhat 

 yellowish on account of the yellowish recumbent pubescence, which 

 also extends about the suture and the hind margin ; the pubescence 

 mostly short and yellowish, which is especially conspicuous on the 

 parts mentioned above, and intermixed with numerous but rather scat- 

 tered longer (still short) erect black hairs all over the surface, three 

 black hairs becoming paler on the anterior vertical border ; humeri in 

 the lateral bands rather large and prominent, covered with ashy grey 

 tomentum and mainly pale long pubescence ; praealar calli in the late- 

 ral bands large and distinct, triangular, covered with pale yellowish 

 grey dust and bearing short (but longer than that on the disc) yellowish
