Macrocamptoptera, new genus. 



Type. — Camptoptcra mctotorsa Girault. 



A genus similar to Camptoptera Foerster but larger and dis- 

 tinguished by the longer, slender scape, the lack of parapsidal furrows, 

 the somewhat less noticeable abdominal petiole and the coarser body 

 sculpturing. The type species is reconsidered herewith. 



I. Macrocamptoptera metotarsa (Girault).

An examination of the single type specimen of this species brings 

 out the fact that it belongs to this new genus and that its original 

 and revised descriptions are correct in all essential points. But in the 

 table of species of the genus Camptoptera given in Girault (1909a, p. 

 28) in line 9 joint ^ of fnnicle is printed instead of joint 4 of antenna; 

 the second funicle joint was intended. Also the species is more than 

 1.25 mm. in length, distinctly larger than the two known species of 

 Camptoptera. The type is in bad condition, the abdomen broken from 

 the rest of the body but the parts are in excellent condition for study, 

 excepting that the antennal club is missing; the specimen is tag- 

 mounted but the body is not shriveled. However, an antenna was 

 successfully removed and mounted in balsam and also the wings and a 

 fore leg and this mount plainly showed the previous descriptive notes 

 to have been correct. From this mount and the other parts on the 

 tag I have made the following notes which should be considered final. 

 The unique type specimen is in the United States National Museum, 

 Washington, D. C, mounted on a tag bearing the following labels : 

 "Arlington, Va. VI, 28, 1905"; "A. A. Girault, collector."; " Quaint- 

 ance No. 361."; "Type No. 8941."; "Camptoptera metotarsa Girault, 

 5." Also a portion mounted in balsam on a single slide labelled 

 " Hym. slide No. 112," U. S. National Museum, bearing a pair of 

 wings, a fore leg and an antenna. 



Abdomen with a short petiole. Body with distinct scaly sculpture. 

 Parapsidal furrows absent ; a rather deep ovate fovea on each side of the 

 mesoscutum near the caudal margin at about where, or somewhat more laterad, 

 the parapsidal furrows ordinarily are. Fore wing shaped as in Camptoptera ; 

 the marginal vein straight, moderately long, at least three times longer than 

 wide ; a paired, distinct row of discal cilia along the cephalic margin and a 

 similar line along the caudal margin, both at the wing edge or near the inser- 

 tions of the marginal fringes ; the lines along the caudal margin are relatively
