Barnes & McDunnough, Check List 150, 1917. 

 Ocelli sometimes present but never very easily seen. Proboscis well devel- 

 oped. Maxillary palpi absent. Labial palpi variably developed, sometimes very 

 small. Primaries with vein A simple (or shortly forked, fide Meyrick), Mj 

 and M., very weak or absent; R., often absent; R.„ R^, R^ and R. frequently 

 stalked (the first almost obsolete in Marastnarcha cervinicolor). Primaries 

 with a single cleft and secondaries with two in all but one species of our fauna. 

 Secondaries with a conspicuous double row of black scales on under surface 

 along cubital stem. Veins Mj and M„ very faint. All parts of these insects arc 

 more or less elongate and slender, and in resulting delicacy they rival the crane- 

 flies. The legs are provided with two pairs of spurs on the hind tibiae and a 

 terminal pair on the middle tibiae. The fore and mid tibiae also have bushy 

 scale tufts in some species. 



."Vs pointed out by Meyrick, the black scales on the under surface 

 of the secondaries are an absolute character for the Pterophoridae. 

 With the exception of our one species of Agdistis the North Ameri- 

 can Pterophoridae may be placed at once by the cleft wings, without 

 reference to other structures.
