highly convex fusiform swelling, more or less shining ; 

 posterior end pointed and terminating immediately 

 above the anal cleft, anterior extremity rounded and 

 terminating well within the cephalic margin ; central 

 fusiform swelling with two subdorsal rows of large, 

 deep punctures, which take the same contour as the 

 margin of the swelling ; margins broad, sloping 

 downwards, low convex, and deeply and irregu- 

 larly grooved and punctured. Antennae (figs. 3, 

 3 n) usually with eight joints, but examples occur 

 with only seven ; in the former the third joint is 

 slightly the longest, but not much longer than the 

 second ; there is a very long hair on the second and 

 fifth joints ; the rest are rather short, especially those 

 on the sixth and seventh joints ; formula 3, 2, 4, 5, 6, 

 7 (8, 1) ; formula of seven- jointed anteiina3 3 (2, 4), 

 (5, 6) 7, 1. Legs (figs. 4, 4 a) comparatively short; 

 coxa unusually large, being nearly one third of the 

 length of the femur ; tibiae and tarsi gradually dilated 

 towards the tibio-tarsal articulation, giving the legs a 

 peculiar swollen character; the tarsus is also nearly 

 equal in length to the tibia. Marginal secreting spines 

 (fig. 5) long and stout ; inner connecting tube long. 

 Transversely ovate forms, long, 4' 50-7 mm. ; wide, 



5-7 mm. 



Ovate forms, long, 6-8 mm. ; wide, 4-4' 50 mm. ; 

 high 3-4* 7 5 mm. 



Female at period of fecundation (fig. 2) resembling 

 more or less the form of the old adults; colour 

 ochreous brown, central fusiform swelling with one 

 dorsal and two subdorsal, irregular, converging bands 

 of dark madder-brown, and a series of large spots of 

 the same colour extending along the centre of the 

 broad margins ; the whole area of the body studded 

 with a coarse, white, farinose secretion, less dense 

 upon the dark dorsal bands. The hairs of the anal 

 ring are usually covered with secretion, and project 

 beyond the anal lobes as a pencil of pure white wax. 

 Marginal fringe of delicate white filaments, more or
