session have the same suctorial organs as P. Capitis, 

 incUiding the spongeous masses in the sucking-lnbe with 

 their thread-Hke ligaments. The antennas exhibit, but very 

 indistinctly, similar nerves to those of P. Capitis, and their 

 terminations are also the same in structure. The same 

 suctorial organization exists in Ha^matopinus Suis, the para- 

 site of the hog ; in Trichodectes scalaris, the parasite of the 

 ox ; and in a great number of parasites of the same and 

 nearly-allied genera. 



If we thus read off the habits of these creatures by the 

 structure of their oral organs it would appear that it is not a 

 blood-sucking animal, and that its natural food is the fluid 

 exhalations of the human body through the sudoriferous 

 ducts, but that if blood were found there is little doubt that 

 it would imbibe it. All the authors who have examined and 

 described the two species of Pediculus agree in asserting 

 that they do not inflict any pain during feeding on the fluids 

 extracted from the human skin.

Variety of Melitma Euphrosyne. — This female Euphrosyne 

 has the basal half of all the wings black, and presenting a 

 very marked appearance; in the fore wings there is a double 

 fulvous spot in the middle of the black area, and in the hind 

 wings there is a smaller crescentic mark of the same colour :

the situation of these several markings is distinctly shown in 

 the illustration. The specimen is in the rich collection of 

 Mr. S. Stevens, who has lent it to me for the express purpose 

 of figuring in the ' Entomologist.' I have now only to thank
