120 Mr. Children's Abstract of the Characters of 



grass, morsels of leaves, bark of trees, &c. and which it 

 drags about with it by means of the anterior or pectoral 

 feet (hence called sacciferous larvae), the only ones fit for 

 crawling — the posterior being imperfect. 

 Pupa elongate : metamorphosis in the larva-case attached to 

 the branches of trees, or other elevated objects. Prior to 

 the change the larva is reversed ; so that the imago issues 

 from the posterior aperture. (Ochs.) 



Obs. The natural history of the sacciferous insects has for 

 many j'ears engaged the attention of the most distinguished 

 entomologists, and yet much still remains to be done for its 

 perfect elucidation, although many singular and important 

 facts have been discovered respecting them. One of the most 

 remai'kable is that of the females occasionally laying fruitful 

 eggs without any previous intercourse with the male : the fact 

 is as unquestionable as it is mysterious, having been confirmed 

 by many experiments conducted with every necessary precau- 

 tion. The most complete are those of Rossi, an account of 

 which is given in a letter on Psyche apiformis, addressed to 

 the Abbate Mazzola. 



I venture to introduce the genus Psyche (which cannot with 

 propriety be arranged with the Tinea;, Schaben?) in this place; 

 since, in respect of the perfect male insect, it forms the fittest 

 passage to the next genus (Liparis). Ochs.* 



A. — Females apterous, hexapodous : abdomen terminated by 

 a pilose tuft : ovipositor exserted.
