 "1815. Labia Leach, Edinburgh Encyc, IX, p. 118." 

 Labia guttata Scudder.

 [Texas.] 



One female; Orizaba, Vera Cruz. Mexico. January 9-16, 1892. (H. 

 Osborn.) [U. S. N. M.] 



This specimen does not wholly agree with Scudder's description, but 

 still seems referable to this species. 

 Labia fiaviscuta n. sp. 



Type: ? ; Orizaba, Vera Cruz, Mexico. January 9-16, 1892. (H. 

 Osborn.) [U. S. N. M.] 



Apparently allied to L. arcuala Scudder, but differing in the elongate 

 pygidium, the shorter exposed portion of the wings, and the predomi- 

 nance of yellow instead of black on the pronotum. From L. championi 

 De Bormans, the only other form to which it appears at all allied, it can 

 be immediately separated by the thirteen-jointed antennae, the shorter 

 exposed portion of the wings, and the narrower pygidium. 



Body of very small size (5.5 mm.) ; greatest width at the apical por- 

 tion of the abdomen; surface of the head and pronotum moderately 

 polished, abdomen and tegmina dull. Antennae thirteen-jointed, the 

 fourth and fifth joints much shorter and more bead-like than the apical 

 segments. Pronotum slightly longer than broad ; anterior margin very 

 broadly rounded; posterior margin gently rounded; laterals parallel; 

 median sulcus reduced to a slight groove on the posterior half. Teg- 

 mina short, not more than one and a half times as long as the pronotum, 

 but slightly extended laterally, the shoulder angles well rounded; 

 apex subtruncate. Exposed portion of the wng very small, apparent 

 only as the extreme tip, and placed next the median suture. Abdomen 

 with well-developed side folds present on two of the median segments. 

 Anal segment and subgenital plate small, transverse, the apical margins
