336 PROCEEDINGS OF THE NATIONAL MUSEUM. vol. o2. 



bases and apices of the hind tibiae dark to blackish ; fore and middle 

 tarsi pale, except the claws; hind tai-si blackish except base of first 

 segment; trochanters, tarsi, and tibiae sometimes whoUy or in part 

 pale ; fore and middle tarsal claws cleft, hind toothed ; middle tibiae 

 with two, rarely three, apical spines, hind tibiae with from fom* to 

 seven apical spines. 



Abdomen. — 3-4 mm. long, slender, first segment elongate and 

 shghtly widened toward the apex; red, nearly always with more or 

 less blackish infusion, this usually near the apex of the abdomen, but 

 sometimes at the apex of the first segment and on the second and 

 third segments; ovipositor 4-5 mm. long, pale red, the sheaths black. 



Described from seven females; specimens from Woods Hole, 

 Massachusetts, to Texas, including Indiana, Florida and Kansas. 



Male. — Similar to the female, except for the following: I^ength, 

 7-8 mm.; color of head varying from entirely black, except for a 

 small pale area behind each eye and a trace of a paler spot above the 

 labrum, to entirely red, except for the mouth parts; proportions of 

 head relatively the same as in the female; antennae 39-40 segmented, 

 the last two segments rather indistinctly separated in the three speci- 

 mens with 40-segmented antennae; parapsidal furrows apparently 

 not crenulate in two specimens, but this seemingly due to their being 

 partially filled with fused foreign matter; the smooth apical lobes of 

 the proepisterna, the front coxae — at least beneath — the venter, and a 

 band on the outer sides of the intermediate coxae blackish or black, 

 sometimes indistinct in old faded specimens. 



Described from 15 males from various parts of Texas (12), Florida 

 (2), Falls Church, Virginia (1). 



In addition to the above specimens I have included here one female 

 and one male specimen, each labeled "Va., July 25, '80, thru C. V. 

 Eiley," which are only about 6 mm. long and are very nmch paler 

 than the lightest of the above specimens, there being no blackish 

 markings except at the apices of the hind tibiae and the hmd coxae, 

 which are darker; the antennae are brownish, and there is a little 

 blackish infusion on the dorsum of the abdomen. Structurally these 

 specimens seem to agree specifically with this, and they present every 

 appearance of being poorly nourished bred specimens which were 

 killed and pimied before the coloring had fully developed.
