on the bluish dorsal stripe as well as on the neighbouring yellow 
subdorsal bands and the pink-red oblique lateral bands, we find 
groups of knobs, which evidently are regularly arranged on both 
sides of the median line, in eight transverse rows, which correspond 
to the annuli composing each segment, the number of the wharts 
in the blue diminishing from before backwards in the ratio of three 
to two to one. Hach knob carries a hair, or at least was originally 
provided with one. On the pink bands the knobs have the same 
hue as the band itself, only a little deeper, in the yellow and the 
blue on the contrary they retain that same pink colour of their 
own. On the anterior row of each segment, where the number of 
wharts in the blue reaches its maximum (3 or 4 at each side of 
the median line) the wine-red colour even extends around the two 
lateral tubercles, and embraces them in one larger deep-red blotch. 
Surveying the whole of the segments, these blotches are seen arranged 
to both sides of the median line in a series marking the subdorsal 
line; this series can be retraced in convolvuli, in the form of 
the rows of dark subdorsal spots described before, which rows are 
in immediate contact with similar ranges of clear yellow-white 
maculae, nearer to the dorsal line, the latter itself being marked 
by dark stripes (8, one behind the other, on each segment). 
When now we pass to the survey of the body-markings of the 
imagines and begin with the abdominal segments of convolvuli, we 
here again meet the dorsal line as a series of little black stripes. 
To both sides of this the subdorsal. design is arranged as a sequence 
of grey areas touching the dorso-lateral colour-markings with a 
special convexly-curved borderline. These fields themselves are com- 
posed on each abdominal ring of three transverse bands: a narrow 
anterior one of white, and two much broader ones behind, the first 
pink, the second jet-black. This set of three transverse bands is 
repeated seven times: .at the end comes one segment with only a black 
dorsal stripe. The ventral border of this lateral pattern forms an 
almost straight line, situated at a certain distance above the row of 
stigmata. The intervening epistigmal seam is coloured less conspi- 
cuously in the same way as the entire hypostigmal ventral surface; 
yet it is possible to distinguish darker sets of hairbundles, which 
associate with the red and black bands, and a row of white bushes 
of hair stretching right above the stigmata. 
Though as mentioned, the ventral side shows no vividly coloured 
pattern, this uniformity of hue is precisely the cause, that a set of 
two dark spots in the ventral middleline, at the front-border of the 
fourth and the fifth abdominal segment, is highly conspicuous.
