Clemens is syjioiiymous with Layara hrnnhycoidcs of the liritisli 

 Museum Lists, diniinisliing tlie number of species by one, and leav- 

 ing us sixty-eight. To this number must be added three species 

 from tlie West Coast subsequently described by Mr. Hy. Edwards in 

 the Proceedings of the California Academy of Science, Vol. 5, i)p. 

 10'.»-1 1 1. Thi.s would make the number seventy-one. 1 find in the 

 collection of the Museum of Comparative Zoology, specimens of 

 racliylia ficus and Amphonyx Antaeus, collected by Prof. Alex. 

 Agassiz at Key West, Florida, and which were not formerly noticed 

 from our territory. These added give us seventy-three species, in- 

 cluding Pachylia lyncea Clem, now rendered somewhat doubtful by 

 the occurrence of P. ficus in Florida. I exclude from our list of 

 species with certainty the Smerinthus pallens of Mr. Strecker as a 

 synonym of Abbot and Smith's juglandis, while the Sphinx eremi- 

 toides* of the same author is most probably a redescription of the 

 Sphinx lugens of Mr. Walker. With the three new species above 

 described Ave shall then have seventy-six species in all, recorded 

 from America north of Mexico and the West India Islands.

]SroTE. — Writing in April, 1863, I referred the genus Crocota to 

 the Arctiidae, wdiere I believe it must remain, since it is excluded 

 from the Lithosians by the presence of simple eyes. Afterwards Dr. 

 Packard refers the genus to the latter group and this course is fol- 

 lowed by Mr. Robinson and myself in our "List" of 18G8. I am 

 indebted to Mr. Wm. Saunders for an opportunity of examining his 

 type of Ardia Umaculata, Can. Ent. 2, pp. 4-6, 18G9, where also 

 the larva is described. It is a female specimen of Crocota quinaria 

 Grote, Avith one of the usual pale spots on the inferior portion of 

 the fore wings much developed. Traces of the others, obsoletely 

 pupillated, are, hoAvever, observable. This is a stouter species than 

 C. hrevicornis. We seem to have tAvo variable species of which the 

 synonymy is difficult. A variety of the C. hrevicornis of Walker 



* The date "May, 1874," to this publication of Mr. Strecker's must be a fictitious one, since 

 I am credibly informed that some of the material described therein was not supplied to him 

 until June of this year. The copies to which I have had access were not received until 



August.
