 Stidia tuherculata Fox, Proc. Acad. Nat. Sci. Phila., 1895, p. 366. 



Male. — Black: Labrum, mandibles except tips, clj^eus except 

 marginal line at base, scape and basal flagellar segments below, space 

 between antennae, pair of minute spots below anterior ocellus, anterior 

 orbits, posterior orbits, line on posterior border of pronotimi, sides 

 of protliorax almost entirely, elongated irregular spot on mesoplourae, 

 large spot on metapleurae, spots on side of median segment, short 

 lateral lines on scutum above base of wings, triangular lateral spots 

 on scutellum approximated medially, fascia on metanotum, oblique 

 lines on dorsum of median segment and spots on its posterior sur- 

 face, larger part of lateral angles of same, fascia of first tergite 

 broken into pair of spots broad laterally, fasciae on remaining tergites 

 continuous, broadly emarginate medially on anterior border and 

 slightly sinuate laterally, ultimate tergite and sternite apically, 

 broad continuous fasciae on other stemitcs narrowed medially, legs 

 except more or less black on trochanters, black lines above on all 

 femora, and black ultimate segment of tai-si, yellow. 



Length.. — 14 mm. 



The ultimate segment of the antenna is longer than its immediate 

 predecessor, narrowed somewhat distally, rounded at the apex, and 

 distinctly curved. The middle femora are serrate; the middle tibiae 

 are distinctly dilated distally, resembhng those of formosa in this 

 respect ; the middle metatarsi are curved and bear a group of spines 

 near the base ; and the ultimate segment of all tarsi is black and that 

 of the anterior pair is distinctly dilated. The dilation of the last 

 segment of the anterior tareus is not symmetrical, being much more 

 prominent on the posterior than on the anterior border of the seg- 

 ment. The second sternite bears a promin.ent median process decidedly 

 hirsute in character. 



This is a well-marked and distinct species. 



Habitat. — Nevada. 



Number of specimens examined — Males, 2 ; females, 0. 

 Type. — In the collection of American Entomological Society of 

 Philadelphia. 



STICTIELLA CALLISTA, new species. 



Figs. 56, 85, 103. 



Male. — Black: Labrum, mandibles except apices, clypeus except 

 narrow black basal border, lovrer part of frons prolonged upward 

 between antennae and narrowly separated from a broad V-shaped spot 

 enclosing the anterior ocellus, broad aiiterior orbits, scape below, 

 broad posterior orbits connected across the vertex and produ(;ed 

 downward on either side the mid Une of the occiput, prothorax except
