HERMINIID.E. 189 



are a considerable number of species in North America, one of 

 which is here described and figured. 



HYPENA BIJUGALIS. 

 (Plate CXLV. y Fig. 6.) 



Hypena bijugalis, Walker, List Lepid. Ins. Brit. Mus. xvi. p. 32, 

 no. 17 (1858). 



This species is found in Nova Scotia. 



" Female. Pale cinereous. Palpi shorter than the thorax ; 

 their plumes not extending to the tip of the third joint. Fore- 

 wings blackish-brown for full half the length from the base, 

 except along the interior border; the outline of this dark 

 part is slightly excavated, and bordered with white towards 

 the base on its hind side, and is slightly oblique on its 

 exterior side, where it has an obtuse indented tooth; sub- 

 marginal line composed of diffuse blackish spots; space 

 between it and the exterior border brownish ; marginal points 

 black, orbicular mark forming a black dot. Length of the 

 body, five lines ; of the wings, twelve lines " ( Walker). 



FAMILY HERMINIID^E. 



In this Family the antenna are pubescent, with two longer 

 cilia rising from each joint, and are often curved, or furnished 

 with tufts of hairs or scales. The palpi are generally arched, 

 but their structure differs in the sexes. The front legs are often 

 thickened, and provided with pencils of silky hair, or tufts of 

 woolly or scaly hairs. There is no frontal prominence, and the 

 wings are not furnished with tufts of raised scales. 



The larvae are short and thick, with sixteen legs, and live 

 more or less concealed ; and the pupae likewise vary in habit. 



This is a larger family than the last, and contains a much 

 greater variety of well-marked genera. A Cuban species is 

 here figured.
