DESCRIPTION OF PLATE. 



Antenna of Psychides. 



The antennse of Solenobiads, which are simple, are not illustrated, 

 nor of Lypusids, which follow both types as illustrated in Figs, i — 3, 

 and in Fig. 4. 



Figs. I a and ib. — Portions of antenna of Luffia lapidella^ lateral 

 and dorsal views. x 60 diams. Each joint carries two 

 pectinations. Scaling, in four rows, occurs only on dorsal 

 aspect of shaft. The slightly clubbed pectinations carry sense- 

 hairs on all aspects. 



Fig. 2. — Dorsal aspect of portion of antenna of Bacotia sepium. 

 X 60 diams. The structure is essentially the same as in 

 L. lapidella ; the clubbing of pectinations is marked. 



Figs. 3a and -^b. — Dorsal and lateral aspects of antenna of Proiitia 

 betulina. x no diams. Same type as last; pectinations not 

 clubbed, more slender and flowing, but sense-hairs in all aspects ; 

 scaling of shaft less regular. 



Fig. 4. — Portion of antenna of Fumea casta. x 70 diams. General 

 form very like Fig. 3, but type entirely different, scaling along 

 whole dorsum of pectinations, which are not at all clubbed, but 

 look so, owing to scaling being terminally denser and somewhat 

 porrected. 



Fig. 5. — One plumule (or pectination) of antenna of Acanthopsyche 

 opacella. x 70 diams. It is shown a little thicker than it 

 should be ; sense-hairs ventrally only, dorsum smooth, ances- 

 trally existing scales (as in Fig. 4) being lost.
