INVESTIGATIONS ON SCIAPHILA -WAIILBOMIANA, ETC. 63 



the varieties communana and virgaureana, a proof that it 

 can be of no great importance either physiologically or 

 systematically. It also occurs in many other TortricidcE, 

 whilst in many of the species it is entirely wanting. 



The pupa of Sc. minusculana is dark-brown, paler on the 

 ventral surface and in the incisions between the segments, 

 darker on the back and on the wing-cases. 



On the back of the 2nd to 8th segments short spines are 

 arranged in two transverse rows, of which those of the an- 

 terior ro^v are much stouter than those of the hinder row% 

 These spines are only faintly indicated on the 2nd and 8tli 

 segments. These are the so-called Adminicula, which are 

 found in all Tor^re^-pupa?, that are protruded from the 

 cocoon at the exclusion of the imago; as also in the Sesice, 

 Psi/c/ndcE, and many other genera. 



At the rounded anal end of the pupa are two extremely 

 small horny points, and several stout bristles, which are 

 curved like hooks. 



As an example of the polyphagous habits of the larva, I 

 will now mention some of the plants from which I have 

 reared this species: Achillea millefolium, Senecio erucifo- 

 lius, Artemisia carnjyestris and vulgaris, Mentha aquatica, 

 Centaurea jacea, Veronica officinalis, Stachys recta, 

 Cratcegus oxyacantha. Chrysanthemum corymbosum, Bu- 

 pleurum falcatum, Vicia sepium, Anthyllis vulneraria and 

 Medicago sativa. 



The perfect insect usually appears in the first half of 

 June. 



I do not know the larva of the var. incertana, neither was 

 Herr Mann able to give me any notice of it.
