238 Siebold's Remarks on 



2. Fumea. The male is provided with pectinated antennae. It 

 can generally stretch its ahdomen lengthways. Copulation with 

 the female takes place outside the case of the latter. 



The wingless female possesses properly developed legs, antennae 

 and eyes. The antennae are moniliform and short, their apices 

 not reaching to the hinder end of the thorax; the abdomen termi- 

 nates with a telescopic ovipositor (capable of being drawn out 

 and in), the base of which is clothed with many woolly hairs. 

 The female, after its escape from the pupa skin, creeps out of the 

 case, and, firmly attached thereto, waits the approach of the male. 

 After copulation the female, by means of its ovipositor, lays its eggs 

 in the empty pupa- skin which remains in the case, and fills it with 

 eggs and woolly hair ; after which, being shrivelled up, it falls off 

 the case. 



3. Talceporia. The male possesses long, simple, filiform an- 

 tennae. It can not elongate its abdomen. Copulation with the 

 female takes place outside the case. 



The wingless female is quite similar to the female of a Fumea ; 

 legs, antennae, and eyes are developed; the woolly hairs at the end 

 of the abdomen, and the ovipositor, capable of being drawn out 

 and in, are present. The only difference lies in the form of the 

 antennae. The filiform antennae are here always longer than in 

 the females of Fumea; they either reach to the hinder end of the 

 thorax or extend beyond it. The female on its exclusion creeps 

 out of the case, with the pupa skin attached to it, which falls off 

 when it has completely quitted it; and then the female, having co- 

 pulated outside the case to which it is firmly fixed, lays its eggs, 

 by means of its ovipositor, in the cavity of the empty case. 



On the Spiral Case of the Larva of a Psyche. 

 This case-bearer, which occurs near Freiburg in Breisgau on 

 stone walls, and has also been found by Kollar on a brick wall at 

 Vienna, must in every respect attract the attention of Entomolo- 

 gists and Physiologists. From most of those which were sent me 

 from Vienna through Kollar's kindness, a Chalcis made its escape, 

 which proved to be a new species, and has received from Kollar the 

 name Chalcis unicolor. From very few pupae only have I hitherto 

 bred vermiform females without ovipositors, males having never 

 made their appearance. My attention was first called to the 

 occurrence of the Psyche near Freiburg by Herr v. Heyden. I 

 had provisionally named it Psyche Helix, but ascertained after- 

 wards that Herrich-Schaffer had already described and figured
