15. SUBULATE (Subulata). When they are attenuated 



towards the end. Ex. Sitaris humeralis. 



16. ELONGATE (Elongata). When they extend beyond 



the anus. Ex. Trox. 



17. DEVOLVING (Obvolventia). When their Epipleurce 



cover a considerable portion of the sides of the 

 alitrunk. PLATE XXVIII. FIG. 7. 



18. COMPLICANT (Complicantza). When they lie a little 



over each other. Ex. Meloe. PLATE I. FIG. 6. 



19. DEHISCENT (Dehiscentia). When they diverge a 



little at the apex. Ex. Pyrochroa. 



20. AMPLIATE (Ampliata). When they are dispropor- 



tionably wide at the end. Ex. Lycus fasciatus. 

 PLATE XIII. FIG. 20. 



21. PLICATE (Plicata). When they have two or three 



contiguous abbreviated furrows which exhibit the 

 appearance of folds. Ex. Pselaphidae. 



22. PERFORATE (Perforata). When a little hole 



appears drilled through them. Ex. Cassida per- 

 forata. 



N.B. Many of the above terms will apply to Tegmina, 

 Hemelytra, Wings, &c. 



A. Side-covers (Epipleurce}. 



1. MARGINAL (Marginales). When they are only an 



inflexed continuation of the margin. Ex. Bti~ 

 prestis. 



2. DISCOIDAL (Discoidales}. When they are a process 



from the disk of the under surface of the elytra. 



Ex. Lampyris, Cossyphus, Cassida, Notodea*. 



Neither Chrysomela nor Imatidium have a discoidal Epipleura ; 

 which furnishes a further proof that Notoclea is distinct from Chry- 

 y and Imatidium Irom Caxsida.
