STHENOPIS BEHRENSII. (Page 105.) 



Through an oversight, the name of this species is erroneously 

 spelled " Behrnsii." It is named after my friend Mr. James Behrens, 

 who has greatly facilitated my studies by the gift of many unique 

 specimens. 



DREPANA SICTJLIFER. (Page 110.) 



Insert before the description the following reference to the original 

 description, Avhich was unintentionally omitted. 



Drepana Siculi/er, Packard, Rep. Peabody Acad. Sci. (1872). 



GASTROPACHA MILDEI. (Page 113.) 



The name G. roseata, on the explanation of Plate 4, should be 

 changed to correspond with the letter press on page 113. The name 

 mt'/dei was substituted for roseaia at the request of Mr. Behrens, who 

 gave me the unique specimen from which the description is drawn. 



NOTODONTA CALIFORNICA. (Page 116.) 



On plate 10, fig. 9 is a reproduction of a sketch of the larva of this 

 species made by Dr. Behr, of San Francisco. 



LEPTARCTIA LENA. (Page 120.) 



Walker's Nemeophtla CalifornicE, is evidently the same insect as the 

 above, a fact which was not discovered, although suspected, until it 

 was too late to correct the syonymy, which must thus stand as follows : 



LEPTARCTIA CALIFORNIA;.

In relation to this species, my friend C. V. Riley writes me as fol- 

 foUows : " I greatly suspect it will have to be referred back still further
