mouth. Proboscis light brown, with short i)ale hairs. Antennse 

 black, third joint more or less reddish, especially at base and on 

 under side, the whole joint sometimes with a greyish reflection. 



Thorax rather dull black, smooth, sometimes with a slight dark 

 green or aenous tinge, especially on the sides. The dorsum bears 

 five longitudinal rows of very minute spines ; the middle row is 

 central, and the outer rows nearly on the edges of the dorsum. 

 Placed on the posterior half of the dorsum, and forming part of 

 the two intermediate rows of minute spines, are two pairs of 

 strong, black, spiny bristles, slightly curving backwards. The 

 front pair are someiimes smaller ajid often absent. The lengths of 

 the two spines forming the front pair often are unequal in the same 

 specimen. 



A strong spiny bristle in front of the insertion of each wing, 

 and a lateral row of three on each side of the thorax, just below 

 the dorsum. Scutellum concolorous, with two long spines; metano- 

 tum shining black. Sternopleura itself wholly grey dusted, the 

 grey not carried forward over the mesopleura or any other portion 

 of the side of the thorax.' Mesopleura shining, often with an 

 aenous or dark green tint, but never grey dusted. 



Abdomen shining violet-black, with scattered, soft short hairs. 

 Sides of second segment often more or less reddish Second seg- 

 ment with one or two comparatively small but distinct bristles to- 

 wards the sides, almost on the posterior border. Third, fourth, fifth 

 and sixth segments each with a strong bristle towards each side, 

 placed near the posterior border, those on the fourth segment being 

 just behind the middle line, although towards the sides of the seg- 

 ment like the others. Occasionally an additional bristle occurs on 

 the fourth segment, and even on the fifth also, placed between the 

 two normal ones. 



Legs. — Coxae reddish yellow, fore pair narrowly at base, 

 and posterior pairs up the middle, black. Femora mainly 

 shining black, but sometimes with a slight dark green tinge, with 

 bases and tips narrowly reddish yellow. The yellow colour is 

 variable in extent, sometimes occupying the greater part of the 

 fore pair, especially on the under side ; also in some specimens 

 reducing the black part on the po.sterior femora almost to a wide, 

 ill-defined band, or confining it (the black) chiefly to the upper side. 



The fore femora in the a' much enlarged below, the enlarge- 

 ment terminating just before the end in a pair of small bumps 

 (inner and outer) almost contiguous, which bear a few very short 

 black spines. Three strong spines occur near together in the 

 centre of the femora on the under side, followed by four or five 

 shorter strong ones placed on a small bump just before the end of 

 the incrassated part ; and these stronger spines form, with some 



1 In this paper, by "sternopleura" I refer only to that subtriangular 

 piece itself which in most Oriental species is more or less grey dusted, but in all 

 such cases wholly so. In the few instances where the g;ey is carried forward in a 

 thin line as mentiop.ed by Herr Meijcre in the European Nemopoda cylindrica, 

 etc., I expressly take note of this fact.
