 scealu, scalu, shell, husk, scale,) 



Scalloped. — Having the edge marked by rounded

Scape, Scapus. — The first joint of the antennae,

Scapella. — The lancets ; four pieces adapted for 

 perforating the food, which, when united, form 

 a tube for sucking purposes. The upper pair 

 represent the mandibulee, and the lower the 

 maxillsD. (L.) 



Scaphiform. — Boat-shaped. (Gr. shaphe, anything
