THE CANADIAN ENTOMOLOGIST. 67 



EUCALYPTERA GIGANTEA, n. sp. 



Ground colour white, overlaid by a creamy tint, uniform, lustrous. 

 Head, thorax and abdomen immaculate. Primaries with a black streak 



through the centre, starting as a point in the cell near the base, extending 

 just above the median vein and broadening very slowly to near the middle 

 of the outer margin, but a little distance from it, where it ends somewhat 

 diffusely. Secondaries a little whiter than the primaries, immaculate. 

 Beneath powdery : primaries suffused with blackish along the costa and 

 through the centre ; secondaries with costal area dusky. The legs are 

 stout and very heavily clothed with hair. 



Expands : 1.56 inches = 39 mm. 



Habitat : Galveston, Texas, in May. 



One male from Prof. F. H. Snow, in good condition ; but becoming 

 greasy. The primaries are narrower than usual, and that character, with 

 the large size, heavy body and simple maculation should make the species 

 an easily recognizable one. 



Lythrodes semiluna, n. sp. 



Ground colour white, with a faint olivaceous tinge. Thorax mottled 

 with olivaceous scales ; defective. On the primaries the basal area is clear 

 nearly to the middle, then conies an olivaceous brown shade extending 

 from costa to inner margin, ificarved, the inner border fairly defined, the 

 outer diffuse and shading into the ground to a point beyond the cell, where 

 another shade, starting from costa before the apex, curves inward and 

 again outward to the outer margin at vein 3. This darker area also 

 lightens outwardly, leaving the apex of the ground colour, and the veins 

 through this area are also white. The ordinary spots are indicated ; the 

 orbicular by blackish scales on the inner shadjng, the reniform by a dusky 

 slender lunule at the end of the cell. Secondaries white, with a narrow 

 smoky margin. Beneath, primaries smoky, fringes white : secondaries 

 white, with an extra median and marginal dark band and a small discal 

 spot. 



Expands : .80 inches = 20 mm. 



Habitat : Cochise County, Arizona, April 8. 



A single male specimen from Mr. George Franck. The body is 

 defective ; but the wings are in good condition and, while the markings 

 are really very different from those of all the other species, the character- 

 istic strigate appearance is obvious.
