found in streckeri when the spots are reduced are obsolete, and the whole is 

 an even deep-brown, paling towards outer margin, which is heavily sprinkled 

 with whitish scales. 9 with a distinct subinarginal row of 4 or 5 yellow spots 

 on secondaries, the one opposite the cell being the largest. Beneath the spots 

 of the secondaries are better developed than in the S , but much reduced wher, 

 compared with 2 streckeri streckeri; the subterminal row is represented by a 

 spot above anal angle, another on vein M2 and a third below costa near end of 

 subcostal vein ; a small spot in the cell is present and a still fainter one below 

 the inception of vein Cu: near inner margin. Expanse $ 55-62 mm., 9 50 mm. 

 Described from 2 $ $ , 2 9 9 . all collected by Mr. Boll. Of these the 5 type 

 and S and 9 co-types are in the U. S. National Museum, the 9 type in the 

 collection of Dr. Barnes. 



The 2 9 9 before us vary somewhat in the niaculation of the 

 primaries; the cotype has the submarginal band broadly connected 

 with the costal spot, a small extra spot below the origin of vein Cui 

 and another above the anal vein near base of wing as is sometimes 

 seen in streckeri streckeri; these extra spots are only very faintly in- 

 dicated by a few scales in the type 9 . There is some slight yellow 

 scaling in the cell of secondaries, indicative of a reduced spot. 



As already stated this species has been largely confused with 

 cofaqui Strecker, Strecker himself describing the S of this species 

 as that of cofaqui; that he was afterwards convinced of his error may 

 be seen in the fact that he later placed all these specimens under 

 streckeri, where they now stand in his collection. The wing shape of 

 the primaries would alone separate the 9 9 of these two species ; in 

 cofaqui the outer margin is distinctly hollowed out apically whereas 

 in streckeri texana it is decidedly rounded ; the ground color and mac- 

 ulation of the underside of secondaries also present points of differ- 

 ence, of which we were able to assure ourselves by a careful com- 

 parison of the two species when visiting the Strecker Collection. No 

 comparison can, of course, be made between the 5 5 as we know 

 nothing of this sex of cofaqui. There are 2 $ $ and i 9 (also from 

 Mr. Boll, we believe) in the Strecker collection which undoubtedly 

 belong to this form. A second 9 , the so-called 9 type of streckeri 

 to which we have already referred, apart from its enormous size (80 

 mm.), differs from the southern Texas specimens in the prominence 

 of the submarginal band of the secondaries and the spot in the cell on 

 the upper side, the former consisting of seven large yellow spots ; on 

 the underside of secondaries the spots are almost as in typical streckeri 

 but much yellower in color. It is possible that this may form a dis- 

 tinct race, indigenous to North Texas, and intermediate between the
