3. Wings not smoky in the Teapa example. 
2. Vulvar lamina about one-sixth as long as segment 9, bilobed, tips of lobes rounded, interval separating 
them varying from an angle less than 90° to almost semicircular. One 2 has the discoidal triangles of 
hind wings 3-celled, and internal triangle of right hind wing 2-celled. 
Both males and one female have the labrum bordered and crossed with reddish-brown. 
Hab. Unirep Sratss, Texas, probably Corpus Christi or the Nueces River (S. £7. 
Aaron’, A. N. S.: 1 3, 3 2).—MeExico, Matamoros! ?, Teapa in Tabasco (H. H.

In the present material the following differences from the description’ of the unique female type are 
observable: the first yellow antehumeral stripe touches the yellow of the anterior mesothoracic border 
below and reaches the antealar sinus above, at which latter it is connected with the second yellow ante- 
humeral stripe (humeral of Selys') (8 ¢, 2 9); or, with its upper end as above, the lower is barely 
separated from the yellow of the anterior mesothoracic border (4 2); or, with its lower end barely 
separated, its upper end reaches the antealar sinus, but is not connected with the second yellow ante- 
humeral stripe (3 2). Front wings: antenodals, ¢ 15-21, 9 18-22; postnodals, ¢ 9-14, 2 9-13; 
discoidal triangle 2-celled (2 ¢, one asymmetrically), 4-celled (2 9, one asym.); internal triangle free 
(1 d), 3- and 4-celled (1 2 asym.). Hind wings: discoidal triangle free (1 ¢ on one side only), 
3-celled (2 ¢, 2 Q one side only in each, 2 2 both sides); internal triangle 2-celled (1 2 on one side 
only), 3-celled (1 2). 
_ Saffron at base of wings hardly extending beyond the basal subcostal cross-vein, or almost absent. 
Vulvar lamina about one-sixth as long as 9, a median basal ventral tubercle on 9. Appendages subequal 
to 10. 
Hab. Mexico, Altamira in Tamaulipas (M. E. Hoag, coll. P. P. C.: one pair and 
29), Santiago Iscuintla [1 ¢], Guadalajara [4 3,1 2] (Schumann) [1 3,2 2] 
and El Castillo [2 ?](J. F. McClendon, coll. P. P. C.) in Jalisco; Guatemata!, San 
Felipe (Hay & Mazon, U.S.N.M.: 23). 
At one time I thought that Cyclophylla sordida, Selys, might be identical with 
+O O05
