PSYCHE. 



[July 1890- 



of medium size ; tarsi of all the feet some- 

 what longer than the tibiae; hind metatarsal 

 joint without bristles. Wing somewhat long- 

 er than the body, slightly pointed ; anal angle 

 obtuse; fourth longitudinal vein slightl}' 

 benl, entering the tip of the wing and 

 scarcely inclined towards the end of the third 

 longitudinal vein; second and third longi- 

 tudinal veins straight, parallel; fifth longi- 

 tudinal vein evenly curved, entering the pos- 

 terior margin somewhat nearer the base 

 than the apex of the wing; posterior cross 

 vein perpendicular to the hind margin, dis- 

 tant about twice its length from the tip of 

 the fifth longitudinal vein; sixth longitudi- 

 nal vein short, distinct. 



5 of the same color as the male. Face 

 rather broad, not attaining to the lower mar- 

 gin of the eyes. Antennae differing pro- 

 foundly from those of the male ; especially in 

 respect of the third joint and its arista; the 

 former being very short, semioval and flat- 

 tened laterally, while the latter, inserted 

 dorsally, and clothed with microscopic pu- 

 bescence, is so long that if reflexed it would 

 reach to the middle of the thoracic dorsum. 

 Front ample; ocelli prominent. The rather 

 large ovipositor, much exserted in all of my 

 specimens, terminates in a comb-like organ 

 with regular, short, blunt teeth. 



(Generic name derived from ircXcopos, enor- 

 mous, and ir£w8iis, provided with a large 

 penis.) 



Peloropeodes salax, n. sp. $. 5- 



Length : $ 2.25 mm. ; $ 2 mm. ; length of 

 wing $ 2.5 mm., $ 2.25 mm. 



Dull metallic green. Palpi black. Face 

 and front metallic green, almost obscured by 

 whitish dust. Antennae black ; pubescence 

 of the elongated third joint of the male, 

 whitish; bristles of the superior orbit black, 

 those of the inferior orbit white. Thoracic 

 dorsum dark metallic green, but so thickly 

 covered with yellow dust, as to be subopaque 

 in the male, opaque in the female; this dust 

 is thickest on the anterior half of the thorac- 



ic dorsum ; scutellum dusted with white with 

 a metallic violet reflection; pleurae opaque, 

 rather thickly covered with white dust. Cil- 

 ia of the tegulae long, yellow. Metallic 

 green ground color of the abdomen some- 

 what concealed by whitish dust; all the seg- 

 ments covered with sparse short black hairs; 

 capsule of the hypopygium black, sub- 

 opaque, with short appressed whitish pubes- 

 cence on its lateral faces and a few short, ir- 

 regularly placed setae in the median dorsal 

 line; the numerous hook-like appendages 

 pale yellow; ovipositor of the female yellow- 

 ish red; teeth of its comb-shaped tip black. 

 Fore coxae entirely yellow, beset towards 

 their apices anteriorly with a few stout black 

 hairs; posterior coxae with infuscated bases. 

 Legs pale yellow, covered with rather stout 

 black hairs, arranged in very regular rows 

 on the tibiae ; the posterior pairs have three 

 spines on their posterior faces. Tarsi black- 

 ened from the tip of the first joint. Halteres 

 yellow. Wings uniform grayish liyaline, 

 somewhat pointed; base lanceolate; the por- 

 tion of the fourth longitudinal vein beyond 

 the posterior cross vein but very slightly 

 bent, its end running parallel with that of 

 the third longitudinal vein. 



Habitat: Milwaukee Co., Wis. 



I have taken two males and three fe- 

 males of this species in a damp and 

 rather dense wood where the under- 

 growth consisted very largely of Boeh- 

 nieria cylindrica and Impatiens fulva. 



Chrysotimus pusio, Loew. (J. 



A niunber of females of this .species 

 captured on the foliage in damp woods 

 near Milwaukee, agree with Loew's de- 

 scription except in the color of the an- 

 tennae. According to Loew the anten- 

 nae are " entirely black," whereas in all 

 my specimens the two basal joints are 

 honey yellow, while the third joint is
