Mar., 1908.] Grossreck : New Geometridje. 31 



Habitat. — Palmerlee, Cochise Co., Ariz., in June. 



Differs from S. inornata Hulst in the color of the background 

 which in that species is pale yellow, and in the cross lines being broad 

 and incomplete, not fine and continuous. It has been erroneously 

 recorded in Science Bulletin, Vol. I, p. 209, as Stergamatcea inornata. 

 The species is named after Mr. Jacob Doll, who collected the 

 specimens. 



A male in good condition from Wilgus, Cochise Co., Ariz., is in 

 the U. S. National Museum and has been made co-type. 



17. Gonodontis ectrapelaria, new species.' 



Expanse, 38-45 mm. Entire moth from above dark fuscous gray, the wings and 

 abdomen sprinkled over with numerous black scales, the space between the antenna; 

 sometimes light gray to almost white. Two lines cross the primaries, the intra- and 

 extradiscal, both of them rather broad, black and prominent. The first begins on 

 costa one fourth out from base and curves far" out toward center of wing, then curves 

 inward to inner margin. The second begins on costa less than one fourth in from 

 apex and after running toward outer margin for a short distance bends inward and 

 extends slightly sinuous to inner margin, the last outward curve quite decided before 

 meeting the edge. The outer area is traversed by a heavy, irregular, black shading, 

 the inner edge of which is diffused, the outer edge defined. Outward of this shade 

 line the ground color of wing is a little lighter than the rest. Outer margin faintly 

 and evenly scalloped. Fringe brownish. Secondaries with a broad, almost straight, 

 slightly diffuse, black line through its center which extends sometimes completely 

 across the wing and sometimes becomes obsolete on the costal region. A broad shade 

 line in the outer area continuous with that of primaries but much fainter. Outer 

 margin and fringe as in fore wings. Large black discal spots on both wings. 

 Beneath, much paler than above, the transverse lines not indicated, but the outer 

 shade lines strongly reproduced on both wings ; discal spots present. 



Types. — Male and female in the collection of the writer; co-type 

 in Brooklyn Institute Museum and others will be placed in Rutgers 

 College collection. 



Habitat. — Stockton, Utah, July 2, August 9-26 (Spalding); 

 Beaver Canyon, Utah, August (Doll). 



Very different from all described American species. The two 

 cross lines seem to be easily abraded and are then scarcely traceable 

 on the dark ground color, but the outer shade and discal spots 

 remain prominent.
