nearly parallel excavations, which run into each 
other. — Ex. Elytra of Colymbctcs adspcrsus ? , and 
Cybister Rceselii. 
18. Undose (Undosa). Having undulating nearly pa- 
rallel broader depressions which run into each 
other, and resemble the sand of the sea-shore 
when left by the tide. — Ex. jCymatodcs* undosus 
K. MS. 
19. Vermiculate (Vermiculata). Having tortuous ex- 
cavations as if eaten by worms. — Ex. Prothorax 
of Colymbctcs Hybncri and transvcrsalis. 
20. Reticulose (lleticidosa). Having a number of mi- 
nute impressed lines which intersect each other in 
various directions like the meshes of a net. — Ex. 
Prothorax of Cybister Pcvselii. 
21. Acuducted (Acuducta). Scratched across very 
finely as if with the point of a needle or pin. — Ex. 
Colymbetes acuductus. 
22. Striate (Striata). Having rather slightly impressed 
longitudinal parallel lines. — Ex. Amara commu- 
nis, &c. 
23. Sulcate (Sulcata). Having deeper impressed lon- 
gitudinal parallel lines. — Ex. Dytiscus margi- 
nalis ? . 
24. Clathrose (Clathrosa). When strias or furrows 
cross each other at right angles. — Ex. Abdomen of

a I do not find in Schonherr (Curculionid. Method. Disj).) any 
genus or subgenus of Rhyncophorous beetles the characters of which 
correspond with those of the insect here alluded to, which I once 
thought might be a Cyphus Germ, but it is not. It appears common 
in Brazil, and I have at least two species °f it.
