ORISMOLOOY. 343 
15. Subulate (Subulata). When they are attenuated 
towards the end. — Ex. Sitaris humcralis. 
16. Elongate (Elongata). When they extend beyond 
the anus. — Ex. Trox. 
17. Obvolving (Obvolventia). When their Epipleurce 
cover a considerable portion of the sides of the 
alitrunk. Plate XXVIII. Fig. 7. 
18. Complicant [Complicantia). When they lie a little 
over each other. — Ex. Meloc. Plate I. Fig. 6. 
19. Dehiscent (Dehiscentia). When they diverge a 
little at the apex. — Ex. Pyrochroa. 
20. AMrLiATE (A?npliata). 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. Psclaphida?. 
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 (Epiptcuree). 
1. Marginal (Marginales). When they are only an 
inflexed continuation of the margin. — Ex. Bu- 
prestis. 
2. Discoidal (Discoidales). When they are a process 
from the disk of the under surface of the elytra. — 
Ex. Lampyris, Cossyphus, Cassida, Notoclea z . 
* Neither Chrysomcla nor Imatidium have a discoidal Epiplcura ; 
which furnishes a further proof that Notoclea is distinct from Chry- 
somela, and Imatidium from Cassida.
