302 ORISMOLOGY. 



9. CONNIVENT (Connivens). The meeting of two lines 

 so as to form an angle. Ex. Streaks on the Under 

 side of Secondary Wings of Thecla Pruni. 

 10. COMMON (Communis). Common to two. When a 

 spot for instance is partly on one elytrum and partly 

 on the other. Ex. Coccinella septempunctata. 



VIII. MARGIN. 



1. CRISP (Crispa). When the Limb is disproportion- 



ably larger than the Disk, so as to render the mar- 

 gin uneven with irregular rises and falls. 



2. UNDULATE (Undulata}. When the surface rises and 



falls obtusely, not in angles. Ex. Margin of Wings 

 of Hipparchia Semele. 



3. CORRUGATE ( Corrugata). When the surface rises and 



falls acutely in angles. Ex. Acidalia luteata, &c. 

 4-. PLICATE (Plicata). Longitudinally or transversely 

 folded ; or so impressed with striae as to have that 

 appearance. Ex. Abdomen of Staphylinus. 



5. DILATATE (Dilatata). Dilated disproportionably 



with respect to the Disk. Ex. Protliorax of Ne- 

 crophorus. 



6. FILATE (Filata). When the edge is separated by a 



channel, often producing a very slender threadlike 

 margin. Ex. Elytra of Choleva. 



7. INCRASSATE (Incrassata). When the margin is dis- 



proportionably thick. Ex. Mr. Marsham's Family 

 of Chrysomela " thorace utrinque incrassato." 



8. INTIRE (Integra). When the margin has neither 



teeth, serratures, nor other incisions. 



9. CHANNEL (Canalt's). An impressed line more or
