the keels, too, being much finer; the yellow mark on the 

 inner orbits is obliquely narrowed above, not of unitbrm 

 thickness, and there is a similar mark above it, which is not 

 the case with the present species ; the puncturation on the 

 mesonotum is finer and closer and does not run into reticu- 

 lations and strife at the base ; the transverse cubital nervure 

 is as long as the basal abscissa of the cubitus, while in tincli- 

 penne it is shorter than it. 



Bhyssa variltneata, sp. n. 



Black, with the following yellow spots : — underside of 

 scape, face, the orbits broadly (except on top), apex of pro- 

 notum (its sides more narrowly), scutellar keels, scutelluni 

 (except at apex), median segment (except round the edges), 

 tubercles, an irregular spot below them, a smaller line under 

 hind wings, a line down the centre of first abdominal segment 

 (narrowed in the middle, the apex wider than the base), a 

 broader line on the apical three fourths of the second (its 

 apex rounded and dilated), a continuous line near the apex of 

 the third, an interrupted one on the fourth and fifth, and a 

 narrower obscure one on the sixth. Legs yellow, the four 

 anterior coxse above, the hinder (except for a broad band 

 above), the greater part of the femora behind and the poste- 

 rior in front in the middle, the base of the four front tibiae, 

 the posterior to beyond the middle, and the tarsi, black. 

 Wings hyaline, iridescent, the stigma testaceous, the nervures 

 black ; a squarish cloud at the end of the stigma, extending 

 shortly beyond the areolet. $ . 



Length 13, ovipositor 12 mm. 



Kuching ; September {John Hewitt). 



Smooth, except the striated mesonotum and the scutelluni, 

 which is punctured. Pedicle of areolet as long as the straight 

 basal branch. Clypeus narrowed obliquely, testaceous, its 

 middle dilated, almost toothed. 



This is the smallest Malay species known. It is near to 

 maculipennis, Smith, which may be separated from it, apart 

 from its much larger size, by the much larger alar cloud, 

 which extends beyond the cubitus, and by the metanotum 

 having three separated yellow spots on the apex, the rest 

 being black.
