consequence of the differentiation of the oblique light stripes which 
ascend in a dorso-caudal direction, and are accompanied along 
their dorsal border by an obscuration of the brown-black ground- 
colour (called ‘“dunkle Grundierung”’ by v. Voss). At their posterior 
top these oblique light stripes exactly pass into the above-mentioned 
white subdorsal spots, in the same way as their accompanying dark 
seams join the black specks, which themselves run on into the dark 
subdorsal lines. A similar broadening and obscuration of the seam, 
as is caused by these specks at the dorsal end of the oblique stripes, 
is also found at their ventral beginning, on the level of the stigma. 
The latter however is situated at the back side of the light oblique 
stria (on the suture between the 3 and 4 annulus), while the 
mentioned dark spot lies before it on the 2 annulus. Still further 
forward to the front side, the corresponding part of the first annulus 
also bears a pair of dark maculae (praestigmal spots). The stigma 
itself is likewise coloured dark. In advance of the stigma the dark 
diagonal stria is still continued in a ventral direction over the poste- 
rior four annuli of the foregoing segment, and reaches the ventral 
border of the broad light substigmal band, where it joins the horizon- 
tal undulating line over the base of the false legs. 
Now in this brown variety of convolvuli we see at once that all these 
spots and stripes are nothing else but more or less differentiated 
parts of the general ground-pattern, which exclusively consists of 
rows of light maculae on a dark ground, keeping rigorously to the 
annuli, and therefore repeated eight times on the succeeding abdominal 
segments. In each row the number of maculae is large, yet tolerably 
constant, viz. + 13 at either side of the median line. 
The above described black spots are formed by the blending of 
dark stripes separating the white specks, the light blotches on the 
contrary by the obliteration of one or more of these stripes. 
Likewise the light diagonal stripes are built up by an obliquely 
rising series of eight light maculae that have increased a little in 
size, the dark seam in the same way by a similar gradation of 
black cubes, lying dorsally to these light maculae. 
Comparing the brown with the green variety, we remark that 
the latter has got nothing left of the entire ground-pattern but the 
larger dark maculae: the subdorsal, the epistigmal, the prostigmal, 
the stigmal and the hypostigmal or the basal spot. Of these the 
epistigma! spot still betrays its original character as a part of the 
dark seam along the diagonal stria by its obliquely extended shape 
in a dorso-caudal direction, pointing so to say to the subdorsal stripe 
of the following segment.
