J ?Q99 5 1 CLARK — TWENTY-FIVE NEW SPHINGIDAE 11 



1922 



Chromis erotus cramptoni subsp. nov. 



Al. ant. long., d\ 34 mm.; 9, 39 mm. Al. ant. lat., d\ 12 mm.; 



9 , 15 mm. Marg. ext., d\ 20 mm.; 9 , 23 mm. 



Habitat. — Agana, Guam. Twelve males and ten females in coll. B. 

 Preston Clark, collected in July, 1920, by my friend Dr. Henry E. Cramp- 

 ton, and presented to me by him. The form bears his name. 



I have hesitated to separate this form in a species so widely 

 distributed and so uniform in its characteristics, but the locality- 

 is so isolated, the characters of the race are so marked, and the 

 series is so long and so unvarying, that such treatment seems 

 advisable. 



Fore wing above: Sub-basal line, 3 mm. in length, from costal margin 

 toward inner margin. Antemedian line, concave basad, extends from a 

 point 11 mm. from the base on costal margin to a black spot at the base on 

 the inner margin. There are postmedian geminate transverse lines; the area 

 between the lines is dark, on costal margin, and from inner margin to a point 

 half-way to costal margin. A postmedian line parallel to the geminate one 

 extends from a point 5 mm. distant from hinder angle to a point 10 mm. 

 from wing apex on costal margin, curving basad as it approaches this mar- 

 gin. Dark shade posteriorly to this line, between it and distal margin, 

 extends from Rl to R3. All these markings are sharp, and uniform through- 

 out the whole series. Hind wing above shows no marked difference from 

 the typical form. 



Fore wing below: A heavy dark brown distal marginal band extends 

 from the wing tip, broadening until between R2 and R3 it is 6 mm. in 

 width, then narrowing irregularly to the hinder angle, where it is 2 mm. 

 wide. This band is heavier in the male. The hind wing below has a similar 

 distal marginal band, 2 mm. wide at the inner angle, and tapering to the 

 anal angle. 



Acosmeryx miskini brooksi subsp. nov. 



Measurements identical with those of A. miskini miskini Murray. 



Habitat. — Lebong-Tandai, Benkoelen District, Sumatra. One male in 

 coll. B. Preston Clark, collected by my friend Mr. Cecil J. Brooks, and pre- 

 sented to me by him. I take pleasure in naming the form for him.
