tions of tlie usual tufts; tarsi touched with gray brown at tips of joints. Hind 

 legs more grayish, tibiae apparently with a white dorsal line ; darker at bases 

 of spurs and paler at bases of tarsal joints. Spurs rather short. The hind 

 legs are present in only one specimen of the type series. 



Primaries pale dull gray-brown with some whitish scales and a variable 

 sprinkling of black ones. There is a rather heavy oblique black dash or spot 

 contiguous to base of cleft and a costal spot above it, preceded and followed 

 by whitish fringes. The first lobe has two faint black costal dots, one apical 

 and one preapical on inner margin, and both it and the second are more or less 

 streaked with the black irroration. There is a subcostal line as in the pre- 

 ceding species, but in this case it is merely an area of the ground color free 

 from both black and white scales, and hence is very inconspicuous. Secondaries 

 and fringes of both wings gray-brown. Expanse 17-19 mm. 



Described from five specimens from Texas. 



Holotype 3 , and two paratypes S from San Benito, March 16-23 and 

 allotype, Brownsville, in coll. Barnes. 



Paratype S, San Benito, Mar., U. S. N. M., No. 23487. 



We have three other specimens in poor condition from the San 

 Benito series. 



Medius is rather distinct by reason of its extreme dullness 

 of color, lack of conspicuous pattern other than the one discal dot, 

 and by the fact that this dot is contiguous to the base of the cleft and 

 not separated from it by pale scales. VVe think that no difticulty will 

 be experienced in placing it by means of the key. 



The life history is not yet known. 



27. OlDAEMATOPHORUS LINUS H. Sp. PI. XLVII, fig. 2. PI. LII, 



fig. 9. 



White. Head with some gray-brown scales above and in front. Antennae 

 dotted with brown above. Palpi small and slender, third joint and tip of second 

 gray-brown. Fore and middle legs with some slender gray-brown stripes, no 

 trace of tufts. Hind legs with gray-brown lines on spurs and just a trace at 

 tips of some tarsal joints; spurs moderate. Abdomen with single dorsal dots 

 in posterior margins of segments, sometimes faintly connected by a dorsal line; 

 also with a gray-brown ventral line and lateral spots or dashes. 



Primaries white, more or less heavily irrorate with brownish black scales 

 which are more numerous toward inner margin and apices of lobes. Costa 

 with a dark dash over base of cleft and another beyond middle of first lobe. 

 Apex of first lobe, inner margin just before apex, and tips of veins in second 

 lobe with brownish black dots. Those on the second lobe are usually indis- 

 tinguishable from the scattered black scales which surround them. There is a 

 dark spot a short space before the cleft which is produced obliquely toward 

 the costal dash. Fringes brownish gray with whitish pencils at tips of veins
