face of the earth. Imago appears in from twelve to fifteen days, and 

 there are at least two successive broods. 



Gelechia beneficentella. — Ground color of head, body and pri- 

 maries pale buff or cream with ochreous shadings and a sparse dusting of 

 blackish scales. Palpi exceeding the vertex, second joint thickened but 

 smooth, terminal joint with two broad dusky bands. Primaries ornamented 

 with numerous, rather indefinite maculae, of a blackish or dark steel gray 

 color, producing on the light ground a somewhat checkered appearance. 

 The dark color predominates toward the apex of the wing, and the outer 

 border and ciliae are of the same dark shade. Secondaries broad, silky, 

 cinereous with slight iridescence, ciliae a shade or two paler. 



Legs cream color, dusted with blackish scales, tibiae of hinder pair 

 densely tufted. Alar expanse from 0.70 to 0.75 inch. 



The first brood of larvae may be found early in May folding the 

 terminal leaves of Solmmm carolinense into round, hollow balls, each of 

 which forms the habitation of a single larva which feeds on the incipient 

 flower buds and the infolded edges of the tender leaves. Length of larva 

 from 0.50 to 0.60 inch, fusiform, greatest diameter o.io. Color dull yel- 

 lowish green with dark-glaucous vesicular stripe. Head horizontal, 

 cordate, about one-half the width of middle segments, black when young, 

 later assuming an olive brown hue. Cervical shield corneous, rectangular, 

 covering about two-thirds of the first segment, of an olive brown color. 

 Piliferous plates minute, pale brown, each giving rise to a short light hair. 



Pupa elongate, dark brown, without marked characteristics, suspended 

 in the midst of a mass of fine, webby matter with which the mature larva 

 fills its leafy domicile, an opening being also prepared through which the 

 future moth can make its exit. Lnago issues within two weeks. A 

 second brood of larvae soon follows. 



The specific name for this insect was selected with reference to its 

 services in the larva state, in preventing, to a considerable extent, the 

 blossoming and fruiting of one of our most pernicious weeds. 



LiTHOCOLLETis GREGARiELLA — Ground color rich purple-brown with 

 golden reflections. Two conspicuous golden-white fascia cross the basal 

 and discal portions of the primaries. The apical one-third is ornamented 

 with two white co>tal streaks and one dorsal streak opposite the inner 

 costal one. Ciliae dingy white, Secondaries very narrow, steel gray. 

 Head purplish, iridescent, antennae dark purple conspicuously tipped with
