imagine that a careful study of the types will settle the question but 

 until we are in a position to do this on a future visit to the New York 

 and Cambridge Museums the matter must remain in abeyance. 



Hydriomena glaucata Pack. (PI. VI, Fig. 4.) 



The unique type 9 from California is figured in the Proc. Bost. 

 Soc. N. Hist. PI. I, Fig. 6, but owing to the rather worn nature of the 

 specimen and the poor reproduction this figure is not very satisfactory 

 as a means of absolute identification ; we be- 

 lieve, however that Mr. Swett is correct in 

 stating (C. Ent. 47, p. 63) that the type exists 

 in the Hy. Edwards Collection in the New 

 York Museum, but we cannot agree with his 

 statements (C. Ent. 47, p. 62) that it is a green 

 form of ruberata; we examined this specimen 

 ''"^- ' a year ago and thought at the time we had 



Uncus of H. glaucata niatched it with a series of specimens taken 



in Sonoma Co. in February, such as we figure on PI. III. Figs. 5-7, 

 and which in the type of Uncus corresponds to what we treat in this 

 paper as edenata Swett ; as however we were unaware at the time of 

 the existence of two species with closely allied maculation we feel that 

 our comparison will need careful revision before we can consider that 

 glaucata and edenata represent forms or races of a single species. 



As already stated we prefer for the present to apply the name 

 glaucata tentatively to the species of which we possess I S ,\ 9 from 

 the San Gabriel Mts. Calif, captured June 29th by V. L. Clemence and 

 received by us from Mr. F. Grinnell Jr. ; we figure the 9 which 

 matches Packard's figure pretty well, being in general however rather 

 darker (which may be due to the freshness of the specimen) but show- 

 ing the greenish shade as mentioned in the description. The S Uncus 

 has a short, moderately narrow neck and very long wide-spreading 

 forks, being closer to crokeri and muscata in this respect than to any 

 other species we know of, but of course dififering widely from these two 

 in length of palpi and general maculation. 



Hydriomena edenata Swett. (PI. Ill, Figs. 5-9; PI. VI, Figs. 5, 7,

The Holotype of this species is a 9 from Eden Valley, Monterey 

 Co., Calif, in the Cambridge Museum ex Coll. Swett {vide C. Ent. 47,
