REVISION OF SOME NOCTUID MOTHS— SMITH. 187 



Park, New Mexico, April 4 (Coekerell); Shovel Mountain, Texas 

 (Barnes); City of Mexico (Druce). 



Specimens from all save the first and last of the above-cited localities 

 are at hand, with a few others that have State labels only. The range 

 extends, therefore, from the boreal area to the Tropics, though prob- 

 ably not to the real tropical fauna. 



In the comments on alhlUnea I referred to the fact that a large 

 economic literature exists for that species. It is not improbable that 

 in great part the species now under consideration is really intended, 

 hence citations must be cautiously made. It is also highly desirable 

 that systematic breeding be done to discover the range of variation 

 and what, if any, differences are discoverable in the larva. 



L. moderata Walker, was described from "localitj^ unknown;" but 

 the type in the British Museum seemed to me American and like diffusa; 

 so the reference was made. 



The range of variation is very like that in alh'dinea., but not so great 

 in contrast. In every respect the insect looks and is paler. When 

 once the attempt is made to separate out, there is no difficulty in 

 arranging the series. 



LEUCANIA LIMITATA, new species. 



Very pale creamy yellow. Head a little rusty in front. Collar 

 gra}^ rather than white inferiorly, limited by a white, surmounted by 

 a black line. Primaries without costal darker shading. Median vein 

 white, margined above by a smok}^ brown line which beyond the cell 

 enlarges into the usual trigonate shading. Below the median vein is 

 a narrow yellow brown shade, the vein itself black edged near the end. 

 A small black basal streak with a very narrow loop-like claviform. 

 Terminal space a little darker. Secondaries white, immaculate. 

 Beneath white or a very little yellowish, the costal region a little 

 darker. 



Expanse. — 1.32 inches (33 mm.). 



Habitat. — Texas, in June (Hulst coll.). 



Only a single male in fair condition. It is unfortunate that no greater 

 material of this species should be available to bring out more clearly 

 what differences exist. 



LEUCANIA TETERA, new species. 



Ground color a pale creamy yellow. Head dull luteous. The white 

 portion of collar crossed by a narrow luteous line; no defining line 

 between the pale lower and darker upper portion. Thorax dull 

 luteous. On the primaries the costal region becomes shaded with pink 

 toward the apex. A small black discal dot. The usual dusky shade 

 above vein 4, but interrupted by two white, black-edged dotlets in the 

 interspaces, marking the subterminal line. Median vein concolorous
