72 CLARK — NEW SPHINGIDAE rvSi/VH^' 



Ampeloeca m3rron texana subsp. nov. 



Al. ant. long., &, 29 mm.; $, 32 mm. Al. ant. lat., cf, 11 mm.; 9, 

 14 mm. Marg. ext., cT, 15 mm.; 9, 16 mm. 



Habitat. — A male (type) from Shovel Mountain, Texas, and a male 

 and a female from Jemez Springs, New Mexico, in coll. B. Preston Clark. 

 The male from Texas was received from Dr. William Barnes, and the male 

 and female from New Mexico, from Mr. J. Woodgate. 



This form clearly belongs territorially to that group of Sphin- 

 gidae referred to by the writer (Proc. N. E. Zool. Club, Vol. VI, 

 p. 68) as occurring along the Gulf States of the United States, 

 and west into Texas and New Mexico, but in this species the 

 western form has departed sharply from A. myron f. cnotus 

 Hubner, of Florida. 



It is much lighter in color than either the typical myron or 

 forma cnotus, following in this respect C. myops occidentalis 

 Clark. It is also a somewhat larger insect. The ground tone 

 of the fore wing and hind wing, above and below, is light brown. 

 The darker markings of the fore wing above and below, and of 

 the hind wing below, are a slightly deeper brown. The contrast 

 between the light and dark areas of the fore wing above and 

 below, and of the hind wing below, is much less than in typical 

 myron, this being especially marked in the male. 



Ampeloeca myron ab. lutescens ab. nov. 



Al. ant. long., cf, 23 mm. Al. ant. lat., cf, 10 mm. Marg. ext., cf, 

 12 mm. 



Habitat. — New York State. One male in coll. B. Preston Clark, re- 

 ceived from Mr. Jacob Doll. 



The ground tone of the fore wing above is yellowish; that of 

 the fore wing below is lemon-yellow The hind wing above is 

 clear lemon-yellow, save for a slight darkening at the anal 

 angle. In other respects it follows the normal myron found in 

 the same locality.
