THE ENTOMOLOGIST. 61 



being carried down ihc abdomen and covered by the elytra, 

 merely leaving the knees and tarsi exposed ; and on the sides 

 and anal extremity of the abdomen were arranged a number 

 of lightish brown-coloured hairs. The dorsal surface of the first 

 seven abdominal segments of the pupa were provided with 

 decorations ; the segments from two to six inclusive having 

 Ivro brown plates each, a narrow one at the top and a larger 

 and broader one at the base, the abdominal segments one 

 and seven only having one decorative plate each, and differ- 

 ing in their positions ; the decorative plate on the first abdo- 

 minal segment was a broadish one, and situate at the base 

 of that segment, whilst there was only a thin narrow plate at 

 the top of the seventh segment. The two horn-like pro- 

 jections on the back of the penultimate segment were also 

 retained during pupation ; but here I detected an alteration 

 from their previous colour, as they were then wdiitish at their 

 lower half, instead of dark brown, as when in the larval state, 

 the upper parts retaining their original colour. After an 

 interval the back of the head and thorax settled down to a 

 bone-white tint, and shortly afterwards became dusted with a 

 cloud of minute pale reddish brown-coloured dots ; the eyes, 

 which up to this time had remained white, now assumed a 

 pale brown pigment, which first made its appearance on one 

 side of the eyes, slowly stole over and imparted a pale 

 brownish tint to them ; the unguiculi were then observed to have 

 become impregnated with a pale pinkish-coloured fluid, and 

 while the eyes were slowly deepening from brown to black, 

 the unguiculi changed their tone from pale to dull pink ; the 

 joints of ihe tarsal articulations then assumed at first a pinkish 

 tint, and, just as was the case with the unguiculi, deepened 

 into dull pink ; the whole of the articulations of the tarsi be- 

 coming in their turn of a pale pinkish colour ; the lower half 

 of the elytra, as seen through the puparium, appeared of a faint 

 bluish cast, shaded here and there by a darker tint ; a thin 

 line of pinkish-coloured pigment was then noticeable running 

 along the base of the labrum ; in some individuals this was 

 represented by a series of dots ; the mandibles, which a short 

 time before had become outlined only with a pinkish fluid, 

 now became entirely so coloured. 



Keeping my attention fixed from day to day upon the little 

 creature, 1 noticed that the anterior markings of the elytra
