72 HYMENOPTERA. 



I quote the original description of this species by Howard 

 (1898) exactly as it was published. 



" L/athronieris cicadae, new species. 



Female. — Length, .74 mm. ; expanse, 1.48 mm. ; greatest width of 

 fore wing, .21 mm. Body long and slender, abdomen acuminate and 

 longer than head and thorax together ; antennae short, clavate, scape 

 rather stout, pedicel still stouter and half as long as scape, ring-joint 

 very minute, almost imperceptible, club stouter than pedicel and as 

 long as scape, compact but rather plainly divided into 4 subequal 

 joints, the apical one being slightly the longest, fusiform in shape and 

 with rather long delicate hairs, especially toward the tip ; wings ample, 

 with short marginal cilia ; stigmal vein not curved and extending into 

 disk of wing at an angle of about 45 degrees from costa. Colour sordid 

 yellowish, occiput black; pronotum dusky, black at sides; abdomen 

 dark at sides ; eyes coral red, almost claret coloured ; antennae slightly 

 dusky. 



Male. — Slightly shorter than female ; abdomen with parallel sides 

 and rounded at tip ; antennae with a dark blotch at base of club. 



Described from two males, two females, reared from eggs of Cicada 

 septendecini , collected by T. Pergande, in Virginia, just across the 

 Potomac River from the City of Washington, in July, 1895. All four 

 specimens mounted on a single slide. Type No. 3850, U. S. Nat. 

 Mus." Pp. 102-103. 



In the same year of its original description it was figured 

 by Marlatt in his bulletin on the Periodical Cicada and later 

 again by the same author (Id., 1907); both accounts, includ- 

 ing the figures are identical. Girault (1907 b) listed the 

 species from its only host, Cicada septendechn Linnaeus. 



Through the kindness of Dr. Howard, whose original de- 

 scription of the species has just been quoted, I have been 

 able to examine the type specimens of this species from the 

 United States National Museum. The species is exactly as 

 is described (Howard, 1898) and figured (Marlatt, 1898, 

 1907), though in the figure the submarginal vein of the fore 

 wing is drawn somewhat too broad. From the four type 

 specimens I add herewith the following supplementary de- 

 scriptive details : 



In the female the antennal club is distinctly longer and less stout than 

 in the male as figured, but one antenna of one of the females on the 

 type slide has the club shaped exactly as in the two males of the type,
