Washington was unfit to describe in detail. The Notodont larva, 

 Mr. Schwarz says, was attenuated behind, green, marked with 

 darker green. The anal feet were not raised. The head was 

 rounded triangular, higher than wide, narrowed above, scarcely 

 bilobed. The Arctian larva had a pale brown head and was 

 covered with dense tufts of stiff, brownish hairs. Mr. Caudell 

 is now in this region and may possibly secure more perfect ma 

 terial of some or all of the species.* 



Dr. Dyar further showed specimens of the moth of Catastega 

 timidella Clem., an inflated larva, pupa shells, larval work and 

 a parasitic fly, Eulasiona comstockii Towns., bred from this 

 moth. The genus Catastega was founded by Clemens on three 

 larvse with peculiar habits, the moths of which were unknown 

 to him and to all subsequent students. Stainton suggested in 

 his edition of Clemens' papers, that the genus might belong to 

 the PhycitidaB, a very plausible suggestion, as many Phyciticls 

 have habits very similar to those described for Catastega. The 

 only objection to this suggestion is that it does not agree with 

 the facts. Mr. Busck has bred, on a different plant, a new 

 species of Gelechia with Catastega-like habits. He had, there 

 fore, concluded to refer Catastega as a synonym of Gelechia. 

 But the same objection applies as to Stainton's suggestion. The 

 moths are Tortricids. Catastegj timidella larvae occurred 

 commonly on oak at Bellport, N. Y. The larvaB were matured 

 in September or later and the moths emerged at Washington 

 the following May. Unfortunately the two specimens obtained, 

 both females, were considerably injured in a badly constructed 

 cage, and Dr Dyar does not feel certain as to what known 

 species they should be referred as imagoes. He suggested in 

 regard to the other species of Catastega that C. haniameliclla 

 Clem, might be Semasia argutana Clem, and C. aceriella 

 Clem., Proteoptcryx spoliana Clem. 



Dr. Dyar showed specimens of two butterflies from the 

 Olympic Mountains, Washington State, an Erebia and a Bren- 

 this, sent to the National Museum by Mr. C. V. Piper. The 

 Erebia is E. vidleri Elwes, hitherto only recorded from the 

 Fraser river, British Columbia. The Brenthis may be identified 



*Mr. Caudell has since returned, and has bred Mieza psamm t'/is, veri 

 fying my identification. H. G. D.
