 nished with fine black hairs ; fronto-orbital bristles long ;ind numerous, being very 

 thickly set and rather irregular in the males ; antennre rather long, the second joint

 especially in the females ; arista long, and thickened for half its length ; palpi 

 rufous ; thorax shiny blue-black in the male, with a little grey or tawny pubescence 

 on the sides and front margin, and marked with five rather indistinct longitudinal

 more pubescence ; the external dorso-central bristles ai-e four in number behind the ["2041 

 transverse groove ; scutelluni rufous ; abdomen black, with the sides and anus red Oct., IS. •!.

 This species is so similar in most of its characters to C. analis, that I shall only 

 point out the chief marks of distinction between them. The antennae are shorter, 

 and the third joint is narrow and undilated ; the fronto-orbital bristles are less 

 numerous, being placed further a])arfc ; the palpi are dark at the base, and have their 

 ends quite pale ; the first abdominal segment has no large seta; on its margin, and 

 the second segment is armed with only two spines instead of four, as in C. analis. 

 This is also rai'e ; Air. Eillups sent me one for my inspection, bred from Saturnia 

 carp ill i.

 This species bears a great general i-esemblance to both the preceding ones, and 

 Fabricius probably confounded all three together. The eyes are approximated in 

 the male, and moderately remote in the female ; the fronto-orbital bristles are 

 numerous, but not very large ; the antennae are black, those of the male have the 

 second joint elongated, and about two-thirds of the length of the third, which is 

 rather narrow ; in the female the second joint is rather short, and only about half 

 the length of the third, which is wide ; the arista (especially in the male) is long 

 and thickened for about half its length ; the palpi are testaceous ; the thorax in the 

 male is shiny blue-black with little pubescence, and rather indistinctly marked on 

 the front part with four longitudinal lines of moderate width; in the female the 

 thorax is covered with hoary pubescence or tomentum, and very distinctly striped, 

 the stripes extending over the whole dorsum ; there are four external dorso-central 

 bristles behind the transverse groove ; the scutelluni is tawny ; the abdomen is more 

 or less extensively marked on the sides with red or yellow in the male, the apex and 

 venter being also of the same colour, the dorsum is shiny black, with some white 

 tessellations on the edges of the segments ; in the female the abdomen is dark grey,
