Agrifoliae Essig — (Figs. 8-9, Table III). Fig. 9 sliows the 

 first cerari. The diameters of the bases of the conical setae 

 are subequal to those of the preceding species. The number 

 of wax pores is very much less than in the preceding species, 

 approaching the condition found in citri Risso. There are 

 three conical setae in this cerari. Three ordinary setae are also 

 seen in the cerari. There are two to four conical setae in the sec- 

 ond cerari ; two to three in the third cerari, usually three ; two to 

 three in the fourth and fifth cerari, usually two ; caudad of the 

 sixth each cerari has two conical setff. The conical setae of the 

 first cerari are 14-1(5 microns long and 4-5 microns broad. 



Fig. 8 shows a cerari of the anal lobe. The bases of the conical 

 setae are the largest of any species studied. The posterior conical 

 seta is noticeably larger than the anterior. The number of wax 

 pores is about the same as in obscuriis Essig, but they are much 

 less crowded together and cover a larger space. Eight ordinary 

 setae are seen near the cerari. The anterior conical seta is 27-29 

 microns long and 9-10 microns in diameter. The posterior 

 conical seta is 30-32 microns long and 11-12 microns in diameter. 



Longispiiius Targ. — (Figs. 6, 16, 17, Table IV). Fig. 16 shows 

 the first cerari of this species. The size of the bases of the 

 conical setae is two-thirds that of citri Risso. There are usually 

 three conical setae in this cerari, very seldom four. There 

 are many wax pores and these are crowded together. Four 

 ordinary setae are seen in the cerari. The second cerari has 3-4 

 conical set^, usually four; the third cerari has two conical setae; 

 the sixth has three conical setae; the cerari caudad of this have 

 two conical seta?. The conical setae of the first cerari are 2.6-3.5 

 microns in diameter and 11-12 microns long. 



Fig. 17 shows a cerari of the anal lobes. The conical setae are 

 subequal in size to those of obscurus Essig. The posterior coni- 

 cal seta is strikingly larger than the anterior one. The wax 

 pores are many and crowded together. Four ordinary setae are 

 seen near or in the cerari. The anterior conical seta is 22-25 

 microns long and 8-9 microns in diameter. The posterior one is 

 27-30 microns long and 10-11 microns in diameter.
