The following notes on this species were kindly sent to me by Miss 

 Mary E. Murtfeldt, who bred it at her home in Kirkwood, Missouri : 



"The larva oi Setiostoma xanthohasis was collected September 27th, 

 1890, on a variety of Qiiercus stellata. It fastened two leaves together 

 flatly, but not with the surfaces closely applied — the web under which it 

 was feeding, which was irregularly circular and about ^ of an inch in 

 diameter, being curiously 'boxed' on the margin, 1-5 inch in height 

 where the two leaves were furthest apart. Within this fence it was 

 feeding upon the parenchyma of the under surface of the leaf, rejecting 

 even the smallest veins. 



" At the date mentioned it seemed to be about full-grown, and may be 

 characterized as follows: Length 15 mm., diameter 3 mm.; form sub- 

 depressed, broadest across thoracic segments. Colour, a dull, watery, 

 somewhat livid green, mottled with dull crimson— ventrally as well as 

 dorsally. Abdominal segments marked on dorsum with two broad, 

 irregularly outlined, longitudinal streaks, connected by a transverse, 

 slightly curved crimson line. Piliferous spots and hairs inconspicuous. 



"Head short, thick, pale brown, with central spot of dark brown. 

 Cervical collar narrow, covering only one half of the first segment, horny, 

 pale brown. 



" Anal plate triangular, horny, pale brown. Thoracic legs pale brown. 

 Prolegs similar in colour to general surface. 



" On Oct. I sth, after a period of ten days' quiescence, this larva left its 

 neat case between the leaves and spun up in an inconspicuous, tough 

 little cocoon under the folded edge of one of the leaves. 



"Imago appeared May 15th, 1891."
