A NOTE ON THE MACROTHECIN/E 23 



inner line angularly waved, black, slender, in a white space ; median space 

 with central brownish area, black dusting on costa and an upright black 

 discal mark ; outer line parallel to the outer margin, irregular, edged by 

 whitish ground color ; a blackish shade following, but not quite reaching 

 margin ; a terminal row of fused dots. Hind wing with very light fus- 

 cous shading. Expanse, 12-14 mm. 



Cotypes, 6 specimens. No. 15521, U. S. Nat. Mus. ; La Puefta 

 Valley, Califomia, July, 1911 (Wright & Field). 



One of the cotypes is in the collection of Mr. G. H. Field and one in 

 that of Mr. W. S. Wright. 



Two other unnamed species of this group are before me. 



Alpheias querula, new species. 



Brownish straw-color ; fore wing v\dth the lines black, slender, distinct, 

 scarcely any black powdering on the wings ; a line along costa ; inner 

 line a dark dash on costa and inner margin, preceded by a group of black 

 scales and closely followed by the inner discaJ dot ; outer discal dot sim- 

 ilar ; a few scattered irrorations ; outer line oblique, nearly straight, pre- 

 ceded by irrorations toward costa ; a broken row of terminal dots. Hind 

 wing straw color. Expanse, 10-11 mm, 



Cotypes, 3 specimens, No. 15522, U. S. Nat. Mus.; Brownsville, 

 Texas, May and June, 1904 (H. S. Barber). 



Macrotheca unipuncta, new species. 



Gray, finely powdered with darker ; outer disced mark a large round 

 black spot ; inner obsolete ; lines slender, black, but not so dark as the 

 disced dot, wavy and converging somewhat tow£U"d inner meurgin ; a ter- 

 minal line of dark scales. Hind wing pale fuscous. Expanse, 13-15 mm. 



Cotypes, 4 specimens, No. 15523, U. S. Nat. Mus.; Tryon, North 

 Carolina, May and August, 1 904 (W. F. Fiske) ; New Brighton, Penn- 

 sylvania, July 25, 1905 (H. D. Merrick). 



Of the two new genera described by Doctors Barnes and McDun- 

 nough, Alpheioides parvulalis B. & McD. is before me in specimens 

 recently received through the kindness of Mr. W. S. Wright. Deca- 

 turia pedinalis B. & McD. is, however, not in the National Museum, 

 the authors having so ias failed to avail themselves of their opportunities 

 to benefit future students by depositing types in the National collection, 

 although they described from a large number of specimens.
