476 DR. J. WATERSTON ON A NEW 



Antenna: length 1'25 mm. (see text-fig. 1), consisting of scape, 

 pedicel ring joint, five normal funicular joints and a large 

 sausage-like clu)> (consisting of two funicular and three normal 

 club segments fused). 



Moutli parts. — Labrum (3:2) Avith convex edge and five stout 

 fringing bristles of which the longest equals the breadth of the 

 sclerite. Mandible (4 : 3) bidentate, the upper tooth smaller 

 and rather abruptly and obliquely truncated superiorly. Stipes 

 smooth, about a dozen bristles. Max. palp, (measured along 

 outside edge) 11, 12, 15, 36. In same ratio the breadth of 

 joints 1-3 is about 10 and of 4, 15. •Terminal bristles of 4th 

 about half the length of that joint which bears also 10 stout 

 bristles on apical half and about 20 finer more generally distri- 

 buted. Labial palpus 15, 9, 15 with a breadth at the joints of 

 12-14. Apical bristles distinctly longer than third joint which 

 bears also about a dozen other bristles mainly stout. There are 

 no fewer than 10 (5 : 5) setigerous cells on the lingua. 



Thorax. — Pronotum, in two separate rhomboidal sclerites each 

 with the inner anterior angle rounded off". The outer anterior 

 angle is weakly chitinized. The postero-lateral angle is folded 

 down enclosing the spiracle. Each sclerite bears (mainly on the 

 posterior half) about 50 stifli" bristles of which 6-8 stand along 

 the hind margin between the mid line and the spiracle. Pro- 

 sternum, bristles (8-9 : 8-9). Pro thoracic surface generally 

 nearly smooth, duller and raised reticulate at the sides in front of 

 the spiracle. Mesonotum very broad, only a little longer (7 : 6) 

 than wide, divided almost equally by the transverse suture, the 

 scutellum and axillte being relatively large. Parapsidal furrows 

 deep, mid lobe (measured with the prothorax removed) just 

 longer than the scutellum. The intercept of the parapsidal 

 furrows on the transverse suture (4 times the narrow base of 

 the scutellum) occupies rather over one-third of the breadth. 

 The pattern on the mid lobe is moderately coarse and raised ; 

 of the parapsides and axillae a little lower, while the scutellum is 

 nearly smooth with over 40 bristles equally distributed about 

 a bare mid line. Before the suture the surface is densely bristly 

 and there are about a dozen on each axilla. These notal bristles 

 are a little longer posteriorly with six (3 : 3) above the hind 

 edge of the scutellum distinctly stronger than the others. 



Metathorax. — All over finely reticulate, pattern hardl}^ raised, 

 the three regions well defined. Mid area posteriorly crenulate, 

 lateral areas with one bristle each. 



Propodeon smooth with strong reflections, contoured as in text- 

 fig. 1, shortly rugose i^ound the insertion of the petiole. With a 

 delicate percurrent mid line but no keel. Spiracle facing 

 anteriorly and outwards, only the edge of the peritreme visible 

 from above. There are about 15 bristles behind and beyond 

 the spiracle. 



Mesosternopleuraa nearly all smooth, the only indications of a 

 raised pattern being on the prepectus (posterior half) and in
