G. cerealella. Anacampsis (Butalis) cerealella Harris, Treat, on Ins. 

 2d ed. p. 392 Head and face dull ochreous. Labial palpi pale ochreous, 

 with fuscous ring at the tip and a slight fuscous spot on the middle of the 

 second joint. Fore wings pale, shining ochreous, with a fuscous streak in the 

 fold toward the base and a few fuscous scales toward the tip of the wing on 

 the margin ; cilia grayish ochreous. Hind wings grayish ochreous, cilia the 

 same. 



This insect has doubtless been introduced into this country from Europe. 

 My own specimens were obtained from the W. D. Porter wheat, distributed by 

 the Patent Office at Washington City. The seed of this wheat was originally 

 procured from Mount Olympus in Asia, and from two heads of this as a be- 

 ginning was grown in the District of Columbia the grain distributed in the 

 years 1854 and 1855. The insect is probably common in the District. 



G. agrim o n iel 1 a . Labial palpi yellowish. Eyes crimson. Antenna? 

 yellowish annulated, with black. Head, thorax and fore wings blackish some- 

 what suffused with a greenish hue, the latter black beyond the middle, with 

 a pale yellow band, somewhat hooked on the costa, at the apical third of the 

 wing. Hind wings blackish-brown, cilia the same. 



The larva may be found about the middle of June, nearly full fed, in the 

 leaves of Agrimony, (Agrimonia Eupatoria) which it rolls and binds together 

 with silken threads. The body of the full grown larva is colored obscure 

 green, dotted with black dots. Head and shield pale brown. The young 

 larva is flesh-colored and dotted with dark colored dots. The pupa is con- 

 tained in a slight cocoon, sometimes woven between the leaves of its food 

 plant, but usually it is abandoned to construct it. The pupa-case is not 

 thrust from the cocoon at the maturity of the insect. 



The June brood of larva become imagos during the latter part of June or 

 the beginning of July. 



Fore wings scarcely pointed. Secondary cell faintly indicated. Subcosto- 

 apical vein forked. The last branch of median bifid. Hind wings emarginate 

 before the tip and slightly beneath it ; with an intercostal cell at the base. 



G.? flavocostella . Labial palpi wanting. Head dull reddish yellow. 

 Antennae blackish-brown, yellowish toward the base. Thorax, disk black, 

 front and sides dull yellow. Fore wings black, with a broad, pale yellow 

 costal streak, extending from the base nearly to the tip of the wing, undula- 

 ting from the base to the middle of the wing and dilated into an angle at the 

 apical third, with a faint, yellowish streak produced from the apex of the 

 angle toward the inner angle of the wing. Hind wings dark brown, cilia the 

 same. 



This insect does not, probably, belong to the genus under which it is placed. 

 As the labial palpi are wanting, I include it here from its general structure 

 and appearance, not knowing otherwise where to place it. 



One specimen from A. I. Packard Jr., of Brunswick, Maine. 



The second joint of labial palpi moderately thickened. Hind wings deeply 

 emarginate beneath the tip, which is produced. 



G.? roseosuffusella . Labial palpi, second joint whitish spotted with 

 dark fuscous ; the third dark fuscous annulated with two white rings. Head 

 and thorax ochreous, tegulse with a dark-brown spot in front. Antennae 

 dark fuscous, annulated with whitish. Fore wings dark brown, ochreous 

 along the inner margin, where it is suffused with roseate. At the base of the 

 wing is a white spot containing a dark brown dot, and near the base an ob- 

 lique white band. About the middle of the wing is a large white spot or in- 

 distinct broad band, irrorated with dark brownish and tinted with roseate on 

 the inner margin. Near the tip is a costal white spot and a roseate spot
