76 THE entomologist's UECORIJ. 



whitish patches run along, one on each side of the abdomen, lielow the 

 spiracles. These white patches produce a marked effect on the black 

 ground-colour, and there can be no doubt that the pattern of colora- 

 tion is protective. The skin is somewhat wrinkled and thickly covered 

 with short golden bristles, except on the wing-, leg-, antenna- and 

 maxilla-cases. These are smoother, of a greenish-black hue, and some- 

 what translucent. 



Dorsal view. — The head is placed ventrally, tho pm-thoia.r rounded, 

 bulging somewhat anteriorly ; the iiwso-thora.r is large and swollen, 

 the central area bulging, and rounded, and not medially ridged. The 

 nieta-t/inm.r is narrow, and (with the 1st abdominal segment) con- 

 stricted to form a very marked waist. The ahdaminal s/'<i)nenfs 

 gradually increase in size from the 1st to the third, and then decrease 

 to the anal segment. The first abdominal is more constricted than 

 the meta-thoracic segment, and the girth passes over this segment. 

 The 2nd and 8rd abdominal segments, however, bulge out rapidly, 

 whilst the 2nd, 8rd, 4th, 5th and Gth segments bear a double row of 

 dorsal prominences, corresponding with the segmental sections of the 

 dosal ridges of the larva. Of these the prominences on the 8rd, 4th 

 and 5th are most conspicuous, those on the Gth the least so. 



Lateral view. — The pro-thoracic spiracle is very inconspicuous, 

 black in colour, and placed in the black ground-colour which forms 

 the segmental incision between the pro- thorax and meso- thorax. 

 The wings are dull blackish-green, somewhat translucent, the outer 

 and inner margins sunk in the abdominal segments, which form raised 

 ridges around the wing edges. The spiracles on the 1st, 2nd, 8rd, 

 4th, 5th, Gth and 7th abdominal segments are small, prominently 

 situated, though not conspicuous, placed high up on the sides of the 

 pupa, upon little elevations, below which is a row of small pointed 

 sub-spiracular points, forming a sort of lateral ridge on either side, on 

 the abdominal segments 2-7. Each spiracle has a dead black rim, 

 surrounded by a shiny black cincture. Along the lateral edge of the 

 abdominal segments 2-8, small whitish patches form a broken lateral 

 line along the ridge. 



Ventral view. — The mouth-parts and glazed eye are ventral, 

 greenish-black in tint, the glazed eye edged with shiny black, 

 and extending from the base of the 1st pair of legs to the antennre, 

 which edge the pro-thorax laterally, and are then rapidly brought 

 round into the medio-ventral line of the body, ending with the apices of 

 the wings on the 5th abdominal segment. About half-way down the 

 wings the antennaB hide the maxilbe which pass beneath them, and are 

 not seen again. The joints of the two pairs of legs (which lie between 

 the antennae and the base of the maxilbe), and the joints of the antennfc 

 are not very distinctly marked. The colour of the wings ventrally is 

 somewhat lighter, but still greenish-black. The ventral area of the 

 Gth and following abdominal segments is much restricted, and the 

 skin is folded into deep corrugations. The genital organs are, 

 however, conspicuous. 



The pupa is attached by a cremastral pad, and by a white silken 

 girth. It does not get rid of the cast larval skin.

 drawing (made by Mr. W. Pearce) from which the block for Plate II. 

 has been made.
