more pubescence ; tlie external dorso-central bristles are four in number behind the 

 transverse groove; scufcellum rufous ; abdomen black, with the sides and anus red 

 in both sexes, and transversely banded with white tessellations; the first segment is 

 quite black, armed on the margin with two central dorsal setae, the second segment 

 having four setee ; legs black, hind tibiee ciliated externallj with an even row of 

 rather short bristles ; the wings have the outer cross veins very sinuous. Rare ; 

 Mr. Billups sent me a male, which he had captured at Dulwich.

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 apart ; 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 rare ; Mr. Billups sent me one for my inspection, bred from Saturnia 

 carpini.

This species bears a great general resemblance to both the preceding ones, and 

 FabriciuB 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 tomentura, and very distinctly striped, 

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

 bristles behind the transverse groove ; the scutellum 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, 

 tessellated with black and white, having an indistinct black dorsal band, and some- 

 times a little red on the sides of the middle segments ; the anus is always red ; the 

 first abdominal segment, whioh is black, has two long bristles on the edge in the 

 centre, the second segment has four setee in the same position in the female, and 

 usually six in the male ; the wings have the outer cross veins a little sinuous ; the 

 legs . are black, and have the hind tibia) ciliated, as in the two preceding species. 

 Rare ; it is in Mr. Coryndon Matthew's collection, and in Mr. Verrall's ; the latter 

 kindly sent for my inspection Walker's typical specimen of T. dispecta, which I find
