slightly papillate at bottom, situated between and above the bases of 

 the antennae; the antennae long and slender, the antennae with the 

 first and second segments more or less annular, broader than long, sub- 

 equal in length, much shorter than the third, the third longer than 

 the fourth and shorter than the fourth and fifth together, the fifth and 

 following segments subequal, the ninth segment broadly and rather 

 sharply pointed; the wings, including the veins, the stigma, and the 

 costa, brownish; the front wings with the radio-medial cross-vein 

 present, hyaline; the free part of R4 about twice the length of R5; 

 the free part of M^-hCuj received in the middle of the cell M^; the stig- 

 ma about twice as long as broad, obliquely truncate beyond the radial 

 cross-vein and uniformly convex before it; the hind wings with the 

 cell Ri+2 closed and appendiculate ; the posterior metatarsus slightly 

 shorter than all the following segments together, the second segment 

 one-half the length of the metatarsus and subequeal in length to the 

 third; the saw-guides straight above, convex below, obliquely trun- 

 cated at apex, rounded at angle below, and sharply pointed at upper 

 apical angle. Length 4.5 mm. 



Habitat. — Block Island, Rhode Island (A. P. Morse, Col- 

 lector) ; Missouri (?), larva on blackberry, Riley Collection. 



Since the above was written two additional specimens have 

 been received from Dr. F. H. Chittenden, bred by F. C. Pratt^ 

 from a leaf-miner collected on blackberry at Colmanville, Penn- 

 sylvania. These specimens are identical with the type specimen 

 described above and one of them has been labelled as a paratype. 



This species is named for Mr. S. A. Rohwer, to whom I am 

 indebted for the notes on the described species of Metallus given 

 above. 



Metallus rubi Forbes. 



Body black with the trochanters, the knees, the front and middle 

 tibiae and tarsi, the hind tibiae, though more or less infuscated, and 

 the hind tarsi, white ; the body color varies from brownish to jet black; 

 the antennal furrows distinct above the base of the antennae, puncti- 

 form, varying from a deep well-like puncture to one with flaring sides, 

 some individuals show another puncture on the margin of the antennal 

 foveae, connected with it, and sometimes connected with the above 

 described puncture above the bases of the antennae; antennal furrows 

 obsolete on the front, line-like impressions behind the later'al ocelli, 

 faint along their outer margin and distinct and finely punctiform in 

 front of them; postocular area strongly convex, well separated; the 

 interocellar furrow distinct, concave behind ; the ocellar basin elevated, 

 indicating a pentagonal area, flat or slightly convex on the outer sur- 

 face, depressed close to the median ocellus, the depression connecting 

 with the interocellar furrow; the median fovea situated between and 

 above the bases of the antennae, circular, sometimes small and well- 

 like, sometimes broad with flaring sides; the supraclypeal area uniform-
