23. Flabellate (Flabellatcc). When the antennae on 
one side send forth from the joints, except those 
at the base, long flat flexile branches, which open 
and shut like the sticks of a fan. Plate XI. 
Fig. 17. 
24. Biflabellate (Biftabellatce). When they are fla- 
bellate on both sides. Plate XXV. Fig. 11. 
25. Pectinate (Pcctinatcc). Antennas furnished on one 
side with a number of parallel stiff branches, re- 
sembling somewhat the teeth of a comb. Plate 
XXV. Fig. 25. Plate XI. Fig. 14. 
26. Bipectinate (Bipectinatcz). Pectinate on both 
sides. Plate XXV. Fig. 22. 
27. Duplicato-pectinate (Duplicato-pectinatce). Bi- 
pectinate with the branches on each side alternately 
long and short. Plate XI. Fig. 15. 
28. Ramose (Ttamosce). Antennas furnished on one 
side with two or three irregular lonmsh branches. 
Plate XI. Fig. 18. 
29. Furcate (Furcates). Antennas divided at the end 
into two prongs or branches. Plate XI. Fig. 19. 
Plate V. Fig. 3. 
30. Bipartite (Bipartitce). When they are divided to 
the base into two nearly equal branches. Plate 
XXV. Fig. 20. 
31. Palmate (Palmatce). Very short antennae which 
send forth externally a few long finger-shaped 
branches, giving them some resemblance ofaha?id. 
Plate XI. Fig. 24. 
32. Irregular (Irrcgulares). When the joints of the 
antennas vary so much in size and shape that they 
cannot well be defined. Plate XI. Fig. 22.
