 embiaciiig the whole of segments IH, 1 4 is also heie ; the diag. nal stiipes alone 

 are indistinct aboe the lidge on sfgmcnts 410 ; (here are pornc greeny white or 

 cream-colouied lines fn the ridge below spiiacle otsegmeni 1 1 and veiy often 



some spots or a line of the same ctilour above 

 it ; but these may be entirely wanting; the 

 belly is the colour of the dark lateral portion 

 of segments 11-1 1 with a darker central line 

 except on the front two segments where 

 the colour may be lighter in colour and 

 move appioachmg that of the - saddle ". The 

 length of the processes of segment 4 is I'mm.. 

 and all processes are somewhat pronouncedly 

 spiny or tuberculous at extremities. Owing to the long processes the larva 

 looks thickest at segment 4, espec ally when at rest with its true legs bunched 

 and the fiont of body fiom Rfgmcnt 7 forwa ds raised and bent sharply at

/'u/j./.— This pupa is of ihe type of that of Ruhiiuhi honbmm but is laiger. 

 broadoi- comparat'vsly, generally stouter, the wings more expanded laterally, 

 their dorsal margins more pronout.cedly waved and the rounded tornal angle 

 produced upwards so as to be higher than the general surface of ihi- pupa at 

 segment 6, tho terminal maign therefore, longer here ihan in that s^pecies ; the 

 pupa is broadest at segment G ; the head-vertex isperpendicu'ar to loi giludinal 

 axis of pupa and sepaiaied from tiie ventral surface by a distinct lidge which 

 is continued to the point of a sliort, slout. tria'igularlv pyiamidal projection 

 pointing out forwaids and lateially from each eye : the lalera' oulliiie of the 

 pupa being formed by one side of the pyramid, anotlier side making a ridge to 

 the base of antenna ; the head with segment 2 make an oblong folid, the upper 

 surface be ng the flat second segment, the two prominent eye-projections form- 

 inT the lower anterior corners, the anterior face, the head-verLex. the under 

 surface being the face of head whi^h ish -re ventral; the base of each antenna is 

 slightly prominent foiming a i-niall tubercular projection poiniing tow aids; the 

 lateral outline of the pupa diveiges from the central axis slightly from the 

 hinder niai gin of segment 2 to the shoulder, wheie (here is also a small piomi- 

 nent tubercle pointing outwards, the wiag expansion commencing immediately 

 afterwaids ; the doisal line of pupa ascends from segment 2 (which is pa allel 

 to longitudinal axis) at first at right angles to that axis for a short space, 

 then for about two-thirds the length at an angle of 4;.° in a slight cuive to the 

 apex — the whole slightly carii ated, most highly at apex — whence il fjills rather 

 suddenly and shortly to se;^ment 4 and so to segment 5, whence it rises agiin 

 somewhat gently to near hinder margin of segment G — without carination — then 

 curving down in a quarter circle cuive to creniaster — heie. again, caiinated 

 slightly, the carinatii.n being higher at the hinder margin of each segment
