a distinct, convex hypoclypeal area; the ventral part of the antennal 

 furrows extending from the tentorial invaginations, which are shallow, 

 to a line drawn through the dorsal end of the antennal fovea, and 

 slightly closed just above the base of the antennae by a low, transverse 

 ridge ; the dorsal part of the antennal furrow deep at each side of the 

 postocular area, and fading out opposite the anterior ocellus ; the post- 

 ocular area bounded in front by a furrow uniting the antennal fur- 

 rows of a side, from the cephalic margin of which there extends a 

 wide depression, wider than the ocellus, to the anterior ocellus ; the 

 head not with a pentagonal area; the posterior metatarsus as long as 

 all the following segments together ; the saw guides straight on the 

 dorsal margin, slightly convex on the ventral margin, and obliquely 

 truncate at apex ; the radial cross-vein ending in the cell R4 distinctly 

 before its apex ; wings jnfuscated, veins and stigma brown. Length 

 4 mm. 



Hab. Missouri (Riley), Illinois (Forbes), Rhode Island 

 (Morse), and New York (Norton). 



In notes appended, Dr. MacGillivray says : 



"I have before me for study four specimens from 

 the United States National Museum, all from the Riley collec- 

 tion, one bred from a leaf mine on blackberry, two types from 

 Professor Forbes and a single specimen from Rhode Island. 

 This species varies greatly in the amount and intensity of the 

 rufous color on the mesonotum. The type of capitalis is ap- 

 parently an immature individual in which the mesonotal mark- 

 ings are entirely wanting; in other individuals the mesonotum 

 may be entirely blackish rufous, or with only slightly marked 

 spots, or with the body shining black and with distinct rufous 

 mesonotal area. Forbes' Metallus rnbi, based on males, is 

 black; the male of capitalis differs from the female only in 

 having the mesonotum black, and is undoubtedly the same as 

 Forbes' rubi, while Marlatt's canadensis appears to be simply a 

 form of capitalis with a distinct black and rufous color." 



In the Fourth Report* of the Delaware Experiment Sta- 

 tion (1891) I find a note relative to a leaf-miner in blackber- 

 ries, which J give herewith : 



"Specimens of blackberry leaves infested by a leaf-miner 

 were received June 25, from Mr. P. Emerson, Wyoming, Del.,
