hybernating Lepidoptera than modern society, with artificial requirements, to bachelors 

 of limited means; for she counsels them to defer the happy event, in many cases (par- 

 ticularly in that of the active butterfly) till they are quite faded and worn. Hence 

 probably what appears to us a sluggish habit in Depressaria is in fact a wise economy, 

 whereby that crafty tribe accommodate themselves to circumstances, and save them- 

 selves and their wardrobes for more propitious days. — E. Horton.

Emphytus niger, nitidus, antennarum cingulo et tibiarum basi albis, 

 femoribus rubris. 



This is the first species of Emphytus we have found occasion to 

 describe. It appears that the larvae of Emphytus are not very readily 

 detected, or that they are difficult to rear; at all events, few authors 

 have taken any note of their metamorphoses. Bouche, and subse- 

 quently Hartig, have made known to us the metamorphoses of 

 E. cinctus, L., and of E. perla, Klug. In addition, De Geer and 

 Dahlbom mention the larvae of E. rufocinctus, Klug., and E. succinc- 

 tus, Klug. ; lastly, Brischke has given a figure of E. viennensis, Schr. ; 

 and this is the extent of our knowledge of the metamorphoses of a 

 genus of which nearly forty species occur in Europe. 



The larva of the present species was taken by me during a walk in 

 company with Dr. Wttewaal at de Beele, near Voorst, in Gelderland. 

 It was found for the most part coiled up in a spiral form on the upper 

 surface of oak-leaves. We took some home for the purpose of rearing 

 and figuring them. 



These larvae are dark olive on the back and pale gray underneath. 

 They have twenty-two legs in all. Head anteriorly and on the upper 

 surface clear shining black, with some minute projecting hairs; from 

 an imaginary line running below the antennae the face is brown, with 

 dark brown trophi. The segments are all much wrinkled. A paler 

 longitudinal line runs along the back ; the ground colour above the 

 legs at the side of the body was somewhat darker in ill-defined spots. 

 The thoracic legs were obscure glassy gray, with a broad spot, which
