50 CLARK — THIRTY-THREE NEW SPHINGIDAE [^ol'.^H?' 



Antennae brown above, white beneath. Palpi white, heavily irrorated 

 with brown. Head and thorax gray. Meso thoracic tegulae gray, heavily 

 bordered with black. Patagia white, irrorated with brown. 



Abdomen above: A mesial yellow stripe, slightly interrupted at the 

 segments by slaty blue transverse stripes, which latter are prominent 

 laterally. Abdominal tergites black between the slaty blue stripes. Breast 

 and legs white, heavily irrorated with brown. Abdomen beneath, yellow, 

 lightly irrorated with brown. 



Fore wing above : Of an unusual shape. The costal margin and the distal 

 margin at the wing tip form an exact right angle. Distal margin is straight 

 to 113; from this point it curves gradually and evenly, so there is no hinder 

 angle at all. Wing as a whole gray, with prominent black and white mark- 

 ings. A lighter-colored insect than either S. merops Boisd. or S. justiciae 

 Wlk. A prominent subbasal, longitudinal, brick-red area, 7 mm. in length 

 and 3 mm. in width, similar to that of S. justiciae, but shorter. Double 

 stigma, as in merops and justiciae, but in this form white edged with 

 black. The markings ave very like those of merops and justiciae, but 

 there is no distal marginal band, its place being taken by three broad 

 black lines, edged distally with white, lying between R3 and Ml, Ml and 

 M2, and M2 and SM2. 



Hind wing above: Basal area and median band are slaty blue, similar 

 in area and in width to those of S. justiciae, but partially interrupted at 

 the veins, as in S. merops. 



Fore wing beneath: Gray, irrorated with slaty blue. A broad well- 

 marked submarginal band, strongly convex distad. Basad of this band a 

 distinct geminate interrupted line, with a third line following these two 

 faintly, and parallel to them basally. 



Hind wing beneath: Close to *S. justiciae, but submarginal band brighter 

 white. 



Amplypterus globifer Dyar 



Al. ant. long., 9 , 58 mm. Al. ant. lat., 9 , 31 mm. Marg. ext., 9 , 

 22 mm. 



Habitat. — Zacualpan, Mexico. One female in coll. B. Preston Clark, 

 presented to me by my friend Mr. Roberto Muller, of Mexico City. 



The female of this rare species, not hitherto described, while 

 following the general coloration of the male, is much lighter in 

 tone.
