Distegia, Raf., has been considered part of Lonicera, but it is a characteristic endemic 

 American type, apparently of generic value. It consists of the following forms: D. 

 involucrata {Lonicera involucrata Banks), D. involucrata serotina (L. involucrata v. 

 serotina Koehne), D. involucrata humilis (L. involucrata humilis Koehne), D. flavescens 

 (L. flavescens Dippel), and D. ledebourii (L. ledebourii Esch.). The range is from New 

 Mexico to Alaska, east to Quebec and west to California. 



The few day-flying Lepidoptera noticed at Ward were all of boreal types; namely, 

 Colias (C. eurytheme, C. alexandra, C. alexandra var. alba), Pyrameis {P. cardui, an almost 

 cosmopoKtan species), Chrysophanus, Lycana, Pieris, and Autographa. 



Two small ichneumon-flies collected at Ward were sent to Dr. W. H. Ashmead, who 

 will describe them as new species of the genera Bathynictis and Catastenus. 



' The recently published Sedum stibalpinum Blankinship, is probably identical with 5. sienopelalum 

 rubrolineatunt Ckll., 1891. It is hardly to be considered a distinct spedes, I think; and I learn from Dr. 

 Britton that he also doubts its validity.
