220 BRITISH LEPIDOPTERA. 



on each of the enlarged subsegments ; the series duplicated by a 

 row of rather smaller spots immediately beneath it, and above 

 the spiracles. The head rounded, inclining to be tall and with 

 a slight suggestion of being trapezoidal, brilliantly red, with a 

 smooth but not highly polished surface ; a band of black just above 

 the mouth, the upper portion of labrum and bases of antennae pale 

 yellow, the tips of antennae, lower edge of labrum, and other mouth- 

 parts black; the true legs also black. The body black (duller and 

 less satiny than in C. gallii) ; scutellum black ; anal plates 

 bright red ; caudal horn red, looking like a piece of red coral, rather 

 upright and blunt tipped (? nibbled by other larvae) ; a dark red 

 mediodorsal band, rather broader where it crosses the scutellum 

 than elsewhere ; a broad, bright, rather deep yellow, lateral band, 

 with a series of bright red spots on it just beneath the spiracles, 

 these spots very faintly marked on meso- and metathorax, but quite 

 absent on prothorax. The ventral area with a broad mediodorsal 

 band of pale dirty-looking yellow, broadening on the abdominal seg- 

 ments and including the bases of the prolegs within its area, and ending 

 at the anal claspers. The spiracles white with a black chitinous 

 rim ; the prothoracic and 7th and 8th abdominals slightly larger 

 than the others. Scutellum bordered subdorsally by a short stripe of 

 cream colour, a modification of the subdorsal spots present on the 

 anterior subsegment of other segments from mesothorax to the 8th ab- 

 dominal ; the upper spot on the 8th abdominal elongated upwards 

 towards base of caudal horn. The pigment-spots surrounding bases 

 of shagreen-hairs are largely absent from the middle area of the 

 enlarged subsegment that bears the subdorsal series of spots, being 

 almost entirely restricted to a band on the anterior and posterior 

 portions of the segment save for a few on the centre of the dorsum. 

 The mediodorsal band is bordered with pale yellow behind the 

 caudal horn. Hairs black and very small (Bacot. October 30th, 

 1 90 1. Larvae sent by Fletcher from Malta). ? Third instar:* About 

 •75m. in length ; body yellow or yellowish-green in colour; the head 

 small, almost of the same tint as body, with two dark spots on 

 crown, analogous with the dark markings on either side of each 

 body segment, and in which are the white spots that characterise 

 this larva ; a yellow-green mediodorsal line, bordered on either 

 side with a fine black and white latticed reticulation, which forms, 

 as it were, two lines edging the mediodorsal, and uniting the tops 

 of the black marks in which the white spots are placed ; the 

 spiracular line has more of this reticulation, whilst directly below 

 is a marked yellow subspiracular flange, broken by the segmental 

 incisions ; below this again the black and white reticulation takes 

 the form of two or three white spots, ringed with black at the 

 base of each proleg ; the prolegs themselves are green with a dark 

 spot on the outside of each, whilst between each pair is a smoky 

 quadrangular ventral spot, the spots being less distinct, though 

 present, on those abdominal segments without prolegs ; the true 

 legs are black. The 8th abdominal segment, bearing the black 

 caudal horn, is the darkest segment, but, whilst the gth abdominal
