NORTH AMERICAN LEPIDOPTERA. 187 



IIONORA Grote. 

 (Type mellinella Grt.) 

 Bull. U. S. Geol. Siirv. iv, 702. 1878; N. A. Ento. i, 11. 1879. 



Labial palpi erect, exceeding head, end member quite short ; max- 

 illary palpi distinct, scale tufted on end ; tongue rather long ; ocelli 

 small ; autenuie simple, pubescent ; legs not heavy, tarsi spinulated, 

 spurs slender, short. Genitalia of S after the normal pattern, with- 

 out spines ; last segment of abdomen beneath with two tufts of hairs. 

 Venation : fore wings 11 veins, 4 and 5 long stemmed, 10 separate; 

 hind wings 7 veins, 2 at angle, 3 and 4 stemmed, 7 and 8 stemmed. 



Differs from Heterographls Rag. only in the stemming of 4 and 

 5 of fore wings. I place andalatella Clem, under this genus i-ather 

 than under Heterogrophis, as does Mr. Ragonot, for 4 and 5 are 

 always stemmed, though not always long. If the two genera must 

 be combined by this connecting species, then Heterographis becomes 

 a subgenus only. In his description Mr. Grote says the labial palpi 

 are porrect, but afterwards confesses he mistook the meaning of that 

 term, and meant ascending, or recurved. There is very considerable 

 difference in the palpal structure of the species from sharply erect to 

 obliquely ascending ; one species has the end member horizontal, the 

 second heavier, ascending.
