23. FLABELLATE (Flabellatte). 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 (Biflobdlatcz}. When they are fla- 



bellate on both sides. PLATE XXV. FIG. 11. 



25. PECTINATE (Pectinate}. Antennae 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. Bi PECTIN ATE (Bipectinatce}. 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 (Ramose). Antennae furnished on one 



side with two or three irregular longish branches. 

 PLATE XL FIG. 18. 



29. FURCATE (Furcate). Antennae divided at the end 



into two prongs or branches. PLATE XI. FIG. 19. 

 PLATE V. FIG. 3. 



30. BIPARTITE (Bipartite}. When they are divided to 



the base into two nearly equal branches. PLATE 

 XXV. FIG. 20. 



31. PALMATE (Palmata}. Very short antennae which 



send forth externally a few long finger-shaped 

 branches, giving them some resemblance of a, hand. 

 PLATE XI. FIG. 24. 



32. IRREGULAR (Irregulares). When the joints of the 



antennas vary so much in size and shape that they 

 cannot well be defined. PLATE XI. FIG. 22.
