M 1923 2 ] CLARK — THIRTY-THREE NEW SPHINGIDAE 65 



This is the smallest and one of the loveliest of the Anti- 

 nepheles, and I take pleasure in naming it after my friend Dr. 

 H. L. Weber, who has done such distinguished work in collecting 

 lepidoptera in the Cameroun country. It lies between A. 

 muscosa Holl. and A. lunulata R. and J., and is closer to the 

 latter. 



Antennae brown. Palpi white irrorated with brown, shading to olive 

 green on second and third segments, darkest at tips. Thorax and abdomen 

 above olive-greenish brown. Thorax crested, crest tipped with white. 

 Mesothoracic tegulae tipped prominently with yellow. Legs yellow. Ab- 

 domen beneath white, irrorated heavily on posterior sternites with light 

 yellow and dark red. 



Fore wing above: Olive-greenish brown. Distal margin strongly con- 

 vex. As in A. lunulata, no distinct bands. Lines not lunulate as in A. 

 lunulata, but in the main straight and roughly at right angles to costal 

 margin. Black basal dot; also black basal area close to inner margin. 

 Prominent black stigma between Rl and R2, posteriorly of apex of cell. 

 Small brown apical half -moon, followed by an elongate triangular marginal 

 patch, pointed behind, proximately bordered by a white line, all as in A. 

 lunulata. The triangle, however, is narrower at the base, being but 1 mm. 

 wide, as compared with a width of fully 2 mm. in A. lunulata. The white 

 line is more prominent, and straighter. Area between stigma and discal 

 triangle is lighter in tone than the remainder of the wing. 



Fore wing beneath: Basal area black, olive green along costal margin. 

 A light yellow area, roughly rectangular in shape, extends from a point 

 on costal margin, 4 mm. from wing apex, to R3, thence to the narrow black 

 distal marginal band, less than 1 mm. broad, which it reaches at Ml. From 

 this point it follows the marginal band to the costal margin near wing tip. 

 This yellow area contains one distinct lunulate line, the lunules being con- 

 vex distally. Basad of this line, within the area, is another lunulate line, 

 faint in character. Distad of the distinct line is a third one, distinct, sagit- 

 tate between the veins, the segments pointing basad between the veins. 



Hind wing above: Black, unicolorous. 



Hind wing beneath: Divided into two areas. The first is light yellow, 

 extending from R3 on the distal margin to the wing base, and including 

 the entire area between this line and the inner margin. The second area is 

 black, and includes the anal half of the wing, except where it is light yellow 

 along the extreme anal edge. The wing is crossed by five transverse lines; 

 the three anterior ones traverse the entire wing, while the two posterior 

 ones become obscure at R3.
