416 THE CANADIAN ENTOMOLOGIST. 



Alale and Female. — Eyes large, contiguous at the vertex, black; 

 face semi-translucent, dull orange red. Antennae yellowish brown 

 with erect black hairs. Thorax dull, semi-translucent red, with 

 rather long, blackish hairs in the grooves on top, forming two parallel 

 lines, and a few hairs at the sides; scutellum dull semi-translucent 

 red. Abdomen dull semi-translucent, orange red sparsely, with 

 brown black hairs; tip of abdomen blunt. Under side of body dull 

 red. Legs fuscous. Expanse 3.50 mm. Length L33 mm. 



Since my description of the larva and galls of this species I 

 succeeded in breeding the adults from galls collected in the Valley 

 of the Black Mountains, North Carolina, in September 1906, and 

 they are here characterized for the first time. 



Cecidomyia clavula, sp. nov. 



Female. — Head black, eyes large, contiguous, face pale orange; 

 antennae pale, semi-translucent, orange yellow, banded with black, 

 hairs gray. Thorax above semi-translucent orange, tinged with 

 red; underside orange. Abdomen orange, with yellow hairs. Legs 

 white, with deep black bands. Wings hyaline yellow, with metallic 

 blue and purplish reflections; a broad, dusky grayish, wavy trans- 

 verse band a little beyond the middle, followed by a similar close 

 to the outer margin; on the outer margin is a grayish patch almost 

 connected with the preceding transverse band; costa yellow, 

 deep black below the apex; fringes yellow. Halteres semi-trans- 

 lucent orange. Length 2 mm. Expanse 4 mm. 



Very closely allied to Cecidomyia variegata of Europe. Bred 

 from enlargements of the terminal twigs of Dogwood {Cornus 

 florida). It is the gall described by me in the Bulletin Am. Mus. 

 Nat. Hist., Vol. IV, 1892, p. 269. 



Rhopalomyia remtiscula Beuten. 



Cecidomyia (?) remuscida Beutenmuller, Bull. Am. Mus. 

 Nat. Hist., Vol. XXIII. 1907, p. 392, pi. XVII, figs. 7, 8. 



Male. — Head black; antenna? fuscous. Thorax shining black 

 above, with two pale, parallel* lines dorsally, pleura yellowish brown ; 

 scutellum yellowish. Abdomen dull yellowish, covered with brown 

 hairs. Wings blackish, hyaline. Halteres yellowish, knobs
