NORTH AMKRK'AX T.EPIDOPTERA. 1 1 O 



Tlie vuriations in tliis insect are in the color of the secondaries and 

 the width and color of the niai'ginal band. The color varies from 

 bright red to orange yellow, and the band varies from a narrow 

 black margin to quite a broad terminal band interrupted at the anal 

 angle. The form with deep red secondaries and narrow l)lack mar- 

 gin is typical ; the form with yellowish or orange secondaries and 

 more brownish rather than black margin, is jiumita Strk. Interme- 

 diate forms occur. There are two broods, one in April the other in 

 July. 



The larva, has been figured by Abbot and Smitli, and described 

 from tiie figure by Clemens. A good description is still a <l('!<idcr(iii(m. 



Chcerocampin.*:. 



Usually robust, yet elegant species. Head usually distinct, palpi 

 rarely short and slender ; tongue corneous, usuall}^ as long as the 

 body and often exceeding the tip of abdomen. Antenme various, 

 usually fusiform with a rather long re-curved hook at the tip ; some- 

 times the hook is not well marked, at others it is very prominent ; 

 in Deilephila there is a decided approach to a clavate tip and this 

 genus is most nearly related to the Macroglosdme. The thorax is 

 usually smooth, crested only in Enyo, and the abdomen is usually 

 long and slender, tufted in some few genera. The venation offers 

 nothing abnormal. The wing form is variable, usually angulated in 

 those species in which the abdomen is tufted, while in all the others 

 the outer margin of primaries is sinuate; the apex distinct, a slight 

 excavation below, then outward curve of the middle and a somewhat 

 marked anal angle. There is a tendency to l)right colors, and a 

 banded or strigose style of maculation very different from the simple 

 sober maculation of the Sphlngiace. 



In the Tropics this family is much more numerous in genera and 

 species, and there is an immense variety in form and color, yet they 

 are as a rule readily distinguishable from a peculiarity of habitus, 

 and partly also because almost everything which does not readily fit 

 elsewhere is placed in this subfamily. 



As enlarged by me, several of the genera usually placed in the 

 Macroglosdme find a place in this subfamily. It seemed to me that 

 the former group was so capable of definite limitation, and vet so 

 thoroughly indefinite as usually constituted that a decided advantage 

 would be gained in removing all aberrant material from it and leav-
