APPLE LEAVES, APHIS ATTENDANTS NEW-YORK ACINIA. 67 



is found at this season without any hole in it. In these the worm 

 is still remaining,'to complete its changes and continue its spe- 

 cies the coming summer. And if one of these balls be placed in 

 a tumbler with a piece of paper tied over it, the fly can in due 

 time be obtained therefrom. Its form and size is much like that 

 of the common house-fly, but it has an odd appearance from its 

 wings being opalje and of a tawny brown color, with clear spots 

 upon the inner margin and at the tip. It may appropriately be 

 named the Golden-rod fly {Acinia Solidaginis). 



This fly measures from 0.35 to 0.40 to the tip of its wings. Its body Is of a pale 

 brownish yellow or a tawny whitish color with two darter brown stripes above upon 

 the thorax. The antennae, mouth and legs are dull yellow, the face white, and the 

 top of the head yellowish or reddish brown, with a blackish apet at base where the 

 three oieelli oi- simple eyes are situated. The wings are tawny brownish -yell ow^ 

 with blackish clouds, and with several dots and the veins lighter yellow. On the' 

 outer margin beyond fie middle are two small triangular hyaline spots, and a third 

 longer one inside of these, a large transverse (hyaline spot on the apex and two large 

 triangular ones upon the inner margin, the inner one being larger and prolonged 

 upon the margin to the base. Upon the margin of the wing, in these large hyaline 

 spots are some tawny yellowish dots or small spots, namely, three in the apical spot, 

 one in the smaller triangular one, one or two in the larger triangular one, and three 

 where this last spot is prolonged in the axilla. 



Another pretty species of .Acinia, which is commonly fonnd resting upon brakes 

 in our meadows in midsummer, but which I have not yet discovered in its prepara- 

 tory state, may be named the New-York Acinia lA. Nonccioracensis.) It mea- 

 sures 0.35 to the tip of its wings, and is of a pale brownish or tawny flesh color, and 

 like the preceding species, is clothed with a short stiff beard, which is of a silver 

 gray color, -with scattered black bristles. The orbital edge of the eyes is whitish, 

 and the eyes when the fly is alive are of a pale coppery red color crossed with three 

 golden yellow stripes having a green reflection, the middle one of these stripes being 

 broadest, and the upper one slightly narrower than the lower one. When dead the 

 eyes change to blackish brown and the stripes to black, and they are now much less 

 obvious. The antennae are pale tawny yellow with a simple black seta or coarse 

 bristle on their upper side. The face is whitish with two large black dots in the 

 middle and one on each sid« between the aiitennae and the eye, and a transverse 

 brown spot is placed on each side between the anterior part of the mouth and the 

 eye. The abdomen is dull pale yellow, with the Jtpical segments black except on 

 their posterior margins. The wings are opake, black, with a slender, hyaline-white 

 crescent upon their tips, the anterior horn of which is sometimes tinged with 

 tawny yellow, and upon the middle of the anterior margin is a small streak of the 

 same color. The whole wing is covered, except towards the anterior side and the 

 apex, with numerous white dots, those in and towards the axilla being larger. In 

 some specimens a pruinose powder of a more intensely Vhite oolor forms a ring upon 

 ihe margin of all the larger dots.
