pressed on apical half, scarcely tapering and bluntly pointed, the infe- 

 rior inner edge with a basal depressed distinct laminate pointed tooth, 

 the laminate, more gently sloped, anterior edge of which is minutely 

 denticulate, the inner surface with a similar but not laminate and 

 bliint(?r tooth a little farther from the apex than the basal tooth is 

 from tile base, the apical tooth occasionally subobsolete. Length of 

 body, d", 6.75-8.25 mm., ?, 7.9-9.35 mm.; of antennae, 2.6-4.75 mm.; 

 of tegmina, 1.5-1.9 mm.; of hind femora, 1.4-1.7 mm.; of forceps, cf, 

 2.5-3.5 mm., ?, 2.15-3 mm. 7 cf, 7 ?, and 7 immature specimens. 

 Pilatka, Florida, Feb., 1868 (E. Burgess). 



The pygidium of the immature ? is bifid, and the forceps resemble 

 those of the matui-e animal, but are simpler, irregularly denticulate 

 almost to the tip and lack the regular basal excision. The pygidium 

 of the young cf is also bifid, and as long as broad, and the forceps 

 closely resemble those of the immature female, but are slenderer, 

 more cylindrical, and not so closely attingent. It is apparently a 

 female of this species, but with inaccurate coloring, which is figured 

 in Glover's Illustrations of N. Am. Entomology, Orth., pi, vi, fig. 19, 

 and credited to New York. 



Labia melancholica. Head reddish black, the lower part of 

 the front and labrum reddish luteous, blotched with blackish, the rest 

 tumid, smooth, shining. Palpi rather bright luteous. Antennas 13- 

 jointed, bright luteous on basal third, beyond growing more and more 

 fuscous to the completely dusky tip, the joints longer than usual, but 

 distinctly moniliform, very sparsely pilose. Pronotum slightly broad- 

 est posteriorly, and here as broad as the head, tumid in a large 

 semicircular area in front, and here reddish black, the remainder flat, 

 rather dark luteous; it is a little longer than broad, the sides slightly 

 marginate, the posterior angles broadh- rounded, the hind border 

 otherwise scarcely convex; median impressed line very slight. Teg- 

 mina reddish black, nearly twice as long as the pronotnm, the 

 extremity squarely docked with a slight obliquity; exposed part of 

 wings nearly two-thirds as long as the tegmina, slender, blackish 

 castaneous, Legs luteous, the middle and hind femora slightly cas- 

 taneous. Abdomen long and slender, the sides nearly parallel, dark 

 mahogany brown, blackish toward tlie base, lighter beneath, shining, 

 the surface distantly and very finely and sliglith' wrinkled or sub- 

 rugulose; lateral plications inconspicuous; last segment slightly taper- 

 ing, two-thirds as long as broad, smooth on either side of the middle, 

 slightly tumid and rugulose next base of forceps, and between de-
