CATALOGUE OF NOCTUID/E - SMITH. 173 



examined by Mr. Grote, who is responsible for its reference to 

 afH'rta. 1 can not quite understand why Mr. Grote, after positively 

 making it a. synonynu should still continue to list semiaperta without 

 any reference to signata. 



T. fistula Harv.* 



1878. Harv., Can. Eut., x, 56, Tricholitu. 



HABITAT. California; Ari/ona; (Colorado in September. 



The type is in the British Museum. In the Neumu'gen collection 

 Mr. G rote has labeled specimens of this same species T. complcta Grt., 

 type; but I have 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. 



T. inconspicua Grt. 



1883. Grt v Can. Ent., xv, 129, Tricholita. 

 HABITAT. Arizona. 

 The type is with Mr. Neumregen.

The type of reniforniis is in the collection at Cambridge; that of atra 

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



Genus HYDRCBCIA Gn. 



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



1852. Gn., Sp. Gen., Noct., I, 125. 



The species here placed under this genus have been transferred to 

 Gortyiia, to Apamea, andagainto-Hydrasc/aby Mr. Grote, as his ideas of 

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

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

 quite likely that some of the species do not belong here. 



H. lunata Smith.* 



1891. Smith, Trans. Am. Ent. Sue., xvm, 110, Apamea. 

 1891. Smith, List Lepidoptera, 45, ]l//d>-<icia.
