plate 14, figure '4. A new edition of Driiry's work was published 

 by "Westwood, in 1837 — 1S42, in which this insect is doubtfally 

 referred to the genus Hydrocanipa. 



Dr. E. Emmons, in the l^atural History of New York, Part 

 v., Agriculture, published in 1854, figured this moth on Plate 40? 

 figure 2, apparently copied from Drury's work, as stated by Grote, 

 (Bull. Buf. Soc. Vol. a. page 160), and although no allusion is made 

 to it in the text, he gave it the name of Geometra argentata in the 

 explanation of the plate. Dr. Emmons evidently made a mistake in 

 copying from Drury, taking the name there given to figure 3, plate 

 14, which represents a very different and much larger insect from 

 Jamaica. 



In 18G3, Zeller published his Chilonidarum et Crambidarum 

 genera et species, in which, on page 30, he established his genus 

 Catliarylla, and described among others, this same species under the 

 name of C. nummulcdis, Hueb., and described the true nummulalis 

 Hueb. under the name of C.fuscipes, as shown by Grote and Ro- 

 binson (Tr. Am. Ent. Soc. Vol. II. page 83). In March of the same 

 year Walker (Cat. of the Lep. Het. Part 27) described this spe- 

 cies under the name of michrocJirysella, and placed it in his genus 

 Urola wdiich he established for this and some related species. 



Prof. Grote, in his determination of the moths figured in the 

 work of Emmerson mentioned above (Bui. Buf. Soc. Vol. II. page 

 166), has correctly referred this insect to the genus Agyria Hueb., 

 but has inadvertently taken the incorrect specific name given it 

 by Emmons. 



According to the above history the insect should hereafter 

 be known by the name of Argyria nivalis Drury, and the synonomy 

 will stand as follows : 



Phalena Pyralis nivalis Drury. 



Hydrocanipa ? nivalis Westwood. 



Geometra argentata Emmons. 



Cath'irylla niinimulaUs Zeller (nee. Huebner). 



Urola micJiochrysella Walker. 



Argyria argentata Grote. 



Argyria nivalis Fernald. 



In the synonomy I have given after each name, the authority 

 for the generic combination, but it seems to me better, where only 

 one name is used to give the authority for the species and so pre- 

 fer to call it Argyria nivalis Drury.
