Crambus vachellellus, sp. nov. Plate IX, Fig. 6. 



Head, palpi and thorax lead color with a slight metallic luster. Fore wing dull 

 lead color, inner two thirds, with a number of nearly black lines ; one, beginning at 

 base extends parallel to costa to inner third where it divides for a short distance (about 

 one eighth), then joining again and ending before subterminal band. A second line 

 begins at costa on inner third, runs obliquely outward to band number one but does 

 not touch it, beyond this on costa a third oblique dash. Below band number one be- 

 ginning at base a fourth band descends oblitjuely towards anal angle, but stopping 

 before subterminal band, below this band number live runs parallel to number four, 

 number six, somewhat less distinctly defined parallels the last two. In the space be- 

 yond and below cell and between bands one and four are three short dashes of same 

 dark color. Between these dashes and also between bands four and five the ground 

 color is replaced by creamy white. The ground color of outer third of wing is bright 

 ochreous, crossed from costa to anal angle by subterminal band of metallic lead color. 

 This is angulated in center same as hortellus. An apical dash of metallic and metallic 

 scales on cilia forming a terminal metallic band is also like hortellus. The three black 

 dots on lower half of outer margin are also repeated. Hind wings and under side of 

 both wings are dull lead color, cilia shining but not metallic. Abdomen lead color, 

 legs fuscous. Alar expanse 15 to 20 mm. 



Size and markings same as Crambus Jwrtellits Hbn. but ground 

 color very dark lead grey, instead of pale cinereous as in our eastern 

 specimens of hortellus, and while it may prove to be the same species, 

 the constancy of coloration in the long series before nie will certainly 

 entitle it to a varietal name. 



My species much more closely resembles Meyrick's description of 

 hortellus in his Handbook of British Lepidoptera than Fernald's de- 

 scription of this species in his Crambidie of North America, 



Described from forty specimens collected by Arthur H. A'achell, 

 Verdi, Nevada, June i to 10, 1903, and I take pleasure in naming it 

 after him. Mr. Vachell advises me that the specimens were all caught 

 in long grass.

Thaumatopsis daeckeellus, sp. nov. Plate IX, Fig. 14. 



Eyes large, hemispherical, reddish -brown mottled with black, scales between 

 eyes, long, erect, light and dark brown mottled, same coloration extending over thorax, 

 base of antennre circled by a ring of cream-colored scales. Palpi long as head and 

 thorax, pointed ; long scales mottled ochreous fuscous and dark brown. Antennre 

 half as long as front wing, pectinated, dark fuscous. Front wing ochreous fuscous, 

 almost uniformly distributed over wing, except above median line ground color is a 

 shade or two darker. Conspicuously marked with a narrow white band on median 

 line beginning at base, clearly defined and distinct to end of cell, then gradually turn-
