^GERIA TECTA. n. sp. 



Head jet black, with some white scales at the base of the eyes 

 and between the antennae. Palpi very pale yellow, with the last 

 article black. Antennae blue black above, castaneous beneath. 

 Thorax with narrow buff lines on sides and at base. Abdomen 

 with narrow buff band on basal segment, a wider on the 2d, none 

 on the 3d or 5th, a very wide one on 4th, and narrow on 6th and 

 7th. These bands are repeated on the under side. Caudal tuft, 

 bluish-black above, with some pale buff hairs beneath. Fore- 

 wings with costal and posterior margins, bronze black, internal 

 margin very pale yellow for its basal two-thirds. The discal 

 mark is bronze brown, with the posterior edge orange. The 

 transparent space between the cell is very large, much larger 

 than in ^g, tipidiformis, and allied species, thus leaving the pos- 

 terior margin very narrow. The margins of secondaries are also 

 very narrow, that of the costa being very pale yellow. On the 

 underside of forewings is a bright purplish reflection, not visible 

 above, the margins and nervures being all pale yellow, except on 

 posterior margins, where they are bronze black. Hind wings as 

 on upper side. The legs are blue black, banded with very pale 

 yellow. 2 $. Prescott, Arizona. J.Doll.

, .^GERIA HENSHAWII. n. sp. 



Closely allied to ^g. fuknpcs, Harris, of which it may be an 

 extreme variety. It differs, however, from that species, in the 

 following particulars : The abdomen is wholly black ; the base 

 of the fore wings has a fiery red spot, the discal mark is edged 

 posteriorly with fiery red, and beneath, the costal margin for its 

 apical half, and the margins of the discal mark are of the same 

 color. In other respects it is the same as yEg. fulvipes. 



Exp. wings, 22 mm. 



I?. Mingan Island, Labrador, Mr. S. H. Henshaw, who has 

 kindly aided my labors in this difficult group, and to whom I 

 dedicate this pretty species. 



vEgeria asiliformis. Rott. 



Specimens of this species, exactly agreeing with European 

 examples, have been taken at Walpole, Mass., by Miss C. Guild ; 

 at Winchester, Mass., by Mr. R. Thaxter, and at Cambridge, 

 Mass., by Mr. P. R. Uhler. These are preserved in the collection 

 of the Boston Soc. Nat. History (Nos. 1341, 1342). 



^GERIA TIPULIFORMIS. L. 



In some specimens from Ohio, the vitreous spaces are some- 

 what larger than in the European form, the color is more intense 

 black, the caudal tuft beneath has a larger proportion of yellow, 

 and the insect has generally a more delicate appearance. These 

 may prove to belong to a distinct species.
