Fracker (1915, p. 122). The setae are partly bifurcated and 

 situated on very long and tliin tubercula, some of thom bear a 

 spinoso eharactcr and are short and forked. The latter are developed 

 froni the former e. g. Hemilcuca maia. (Packard, 1914, I'l. XXII). 



They are arranged as on the Saturnndae i. e. Type Je. S. dor- 

 salis is still to be found on the ahdomeii oi Pseudohasis eglanterlna. 



Family Saturnidae. Weismann (1876) drew attention to the 

 spots which on the larvae are different according to their places 

 of birth. I therefore thought it right to draw these spots in their 

 exact shape. Plate XII, fig. 14, 15. 



Packard (1914, PI. XXVI— XXXIII and p. 151—271). Fracker 

 (1915, p. 121 — 122). As early as in instar / the larvae have 

 verrucae which later on become scoli. Secondary setae sometimes 

 make the arrangement a little indistinct. Generally the scoli 

 consist of a conical tuberculum on the top of which some (2 — 10) 

 setae take their origin. The setae often end in a knob and they 

 are glandular hairs. In the successive moults the number of setae 

 often diminishes. On abdominal segment 8 the 'se. dorsales are 

 placed close together. Naked forms are also found, but the first 

 instars have the above mentioned scoli e. g. Bhodia fugax (Packard 

 1914, PI. XXYIII— XXIX). — PouLTOX (1890) mentions depressed 

 scars on the pupa of Saturnia carpina. To me it seems that the Hemi- 

 leucidae and the Saturnidae are side-branches, not directly connected 

 with the Sphimiidae. The description of Saturnia pavonia follows.

Instar 7. Length B'/j n^in- Head black. The tubercula are 

 warts, mostly with 5 — 7 not plumed setae, which have a length 

 of + 700 [j.. On the skin there are no other setae.
