of the Tineids ; nioreovei', the development of the tongue is,. 

 T think, entirely regulated by the mode of life of the moth. 



By removing those species that have spurs we really cut 

 out the whole of Heylaert's subfamilies Canephorinte and 

 Psych oidina3 from the Psychidte. The characters of the 

 Psychidfe, as I now understand the family, are as follows : 



Male. — Head, thorax, abdomen, femora and tibife densely 

 hairy; ocelli large; tongue rudimentary; antennas strongly 

 pectinated; lal)ial ])alpi short, covei'ed with hair ; maxillary 

 palpi absent ; hind tibiii; without any middle spurs, end spurs 

 very short if present ; Avings covered with hair or hairy scales.^ 

 Fore Aving : la forked Avith Ih ; Ir usuall}^ becoming co- 

 incident Avith \h beyond middle; 5 more or less approximate 

 to 4. Hind Aving : Ic present; vein 8 connected Avith the 

 cell by a bar or anastomosing Avitli part of upper median or 

 becoming coincident Avitli 7. 



Fkmale. — AVingless; Avithout legs or well-developed 

 antennas. Larva^ and females case-dwellers. 



This family is divided l)y Heylaerts into five subfamilies,, 

 of Avhich I retain three, all represented in South Africa. 



The following key to the subfamilies is based on that 

 given by Sir (t. Hampson in his ' Moths of India,' vol. i, 

 \). 290, Avho closely followed the classification as originated 

 by Heylaerts. 



1a. Fore Aving with vein lb sending seA'eral l)ranche« to 



inner margin I. (Eceticin.j;. 



B. Fore Aving with only t)ne branch from lb to inner 



margin or no branch at all . . . . - 



2a. Fore wing with one branch from 1 b to inner margin 



II. PSYCHIN.*. 

 B. Fore Aving Avitli no branch from lb to inner margin, 



veins 16 and Ic anastomosing III. CHALiiNi3<;.

' The wings are often apparently naked, but in several cases this has 

 1 leen proved to be due to flying. Bred specimens, killed Ijefore they 

 could fly, show a cei'tain amount of loose hairy covering.
