Desckiptiox of Three Species of Labia from the Soutii- 

 Ell^; Umteu States. 



Labia guttata. Head castaneous black, the labrum dark luteous 

 and the pai-t? above hiteo-castaneous; surface 8mooth, shining, a lit- 

 tle tnniid, with two pair of inconspicuous punctte, one above the 

 other, between the antennse; palpi luteous; antennae 1 2-1 3-jointed, 

 luteous at base, growing infuscated beyond, the apical half brownish 

 fuscous, the whole sparsely pilose. Pronotum slightly narrower than 

 the head in front, of equal width with it behind, of the color of the 

 head, with sides narrowly, but distinctly, and hind border very 

 broadly, but inconspicuously, dull luteous; surface smooth, nearly flat, 

 with a slight median impressed line; sides slightly marginate ; hind 

 border scarcely convex. Tegmina very dark castaneous brown, half 

 as long again as the pronotum, tip squarely docked; exposed part of 

 wings half as long as the tegmina, brownish fuscous, with a large, 

 slightly longitudinal, clear luteous spot in the middle of the base, and 

 the entire edge inconspicuously and narrowly margined with dull 

 luteous. Legs uniform bright luteous. Abdomen with the three 

 or foiu' basal joints blackish, beyond blackish castaneous, the termi- 

 nal joints rich dark castaneous; sides nearly parallel in the cf, some- 

 what convex in the ? , the lateral plications of the second and third 

 ■segments slight, the surface minutely punctured, but the last segment 

 nearly smooth; this segment is (juadrate above in the male, with 

 straight hind border, scarcely depressed posteriorly in the middle, with 

 a short median impressed line not quarter the length of the segment, 

 near the hind border ; in the ? the dorsal segment is tapering, and 

 has a distinct longitudinal impressed line on the whole apical half of 

 the segment. Pygidium of <S as in L. Burgessii. Forceps of ? of 

 the color of the abdomen, but growing darker toward the tip, mod- 

 erately stout, more than half the length of the abdomen, depressed 

 trigonate, with a superior ridge, slightly uptui-ned, slightly incurved 

 on apical half, which is almost laminate and bluntly pointed, the 

 inner edge rugose, with a slight blunt extreme basal tooth; forceps 

 of cf rather slender, rather more than half as long as the abdomen, 

 shaped as in L. Burgessii. Length of body, 6 mm.; of antennse, 3.5 

 mm.; of tegmina and wings, 3.1 mm.; of hind femora, 1.6 mm.; of 

 forceps, d", 2.5 mm., ?, 2.25 mm. 1 cf, 2 ?. Texas (G. W. Belfrage). 



This species agi'ees better than any I have seen with Forf. pulchella 

 Serv., judging from the imperfect descriptions of Serville; but it is
