1918] PupcB of Common SphingidcB 411 



Herse cingulata Fabr. (Fig. 2). 

 Color chestnut ?jrown; body surface smooth and polished, excepting 

 the ninth abdominal segment and the cephalic half of the first eight 

 which are densely punctate; head nearly as broad as long; antennae 

 transversely striated, a few tubercles along the margin and the elevated 

 fiagellum, not extending as far as the prothoracic leg in the female; 

 labrum only visible on the cephalic aspect of the head; mandibular 

 tubercles smooth, scarcely elevated; prothoracic legs with a prominent 

 swelling opposite the exposed portion of the femur; mesothoracic 

 wings extending about three-fifths the length of the body; mesothoracic 

 spiracle with an elevated, black caudal margin which almost conceals 

 the opening; mesothorax prominently excurved along the lateral mar- 

 gin; metathorax with a very rugose triangular, or somewhat cordate 

 area on each side the meson; scar of caudal horn a distinct, slightly 

 depressed smooth area, a longitudinal furrow on the meson and a small 

 tubercle on each side; cremaster deeply rugose. Length 52-62 mm., 

 greatest width lG-18 mm.; length of cremaster 2.5 mm. 



Genus Cocytius Hbn. 

 One species of this genus, C. antcBus, ranges as far north as 

 Florida and occasionally farther. The pupa is the largest which 

 has ever been examined by the writer and differs from all others 

 examined in having a prominent rugose band on the dorso- 

 cephalic portion of the first eight abdominal segments, which 

 is like the rugose areas on the metathorax. These areas on the 

 metathorax are almost identical in shape and sculpturing with 

 those of Herse cingulata. Similar sculpturing occurs on the 

 ridge caudad of the mesothoracic spiracle. The maxillary loop 

 is strongly arched from the surface of the body, almost forming 

 a semi-circle, and its distal end is swollen into a prominent 

 bulb. Rothschild and Jordan describe one species of this genus 

 as having a prominently recurved loop of "two and one-half 

 windings." This seems rather peculiar as this loop appears to 

 have generic value in all other cases. In C. antcEus the lateral 

 margins of the loop are closely set with tubercles, seemingly 

 formed by the transverse constrictions over its surface. Accord- 

 ing to Rothschild and Jordan the other known species with a 

 similar loop has these prominent markings. The body is fusi- 

 form, the labrum visible from the dorsal surface. 



Cocytius antaeus Dru. 



Color chesntut to mahogany brown, with the sculptured areas on 



the dorsum much darker, and occasional blotches and lines of a darker 



color; surface smooth and highly polished, except for the bands of 



sculpturing; maxillary loop extends nearly half the distance to the cau-
