CATALOGUE OF NOCTUID.E SMITH. 173 



examined by Mr. (jrrote, who is responsible for its reference to srmi- 

 aperta. I can not (juite understand wliy Mr. Grote, after i)ositively 

 making it a synonym, should still continue to list seiiiitqjerta without 

 any reference to signata. 



T. fistula Hiirv.* 

 1S78. Harv., Can. Knt., x, 5(1, TriclioUla. 



Habitat. — Califonii;! ; Arizona; Colorado in September. 



The type is in the lliitish Museum. In the Neunmegen collection 

 ]\Tr. Grote has labeled sjx'cimens of this same species T. eompJetn Grt., 

 type; but I luive not found any description of a species under that 

 name. I included the name in my list on the faith of this label, but it 

 must be omitted hereafter.

 1883. Grt., Cau. Ent., xv, 129, Trivliulita.

 1 have not seen, nor do I know where it is. 



Genus HYDRCECIA Gn. 



1837. Gn., Essaisur la class. Noct., 237. 



1852. Gn., Sp. Geu., Noct., i, 125. 



The species here placed under this genus have been transferred to 

 Gorff/naj to Apamca, aiidagaintoS?/(/ra'c/(< by Mr. Grote, as his ideas of 

 types and other matters changed. These changes are not all noted 

 here. In using Hydrcecia now I follow European precedent. It is 

 (piite likely that some of the species do not belong here.
