These has the four groups of circumgenital glands found in 

 zizyphus, but in addition there are one or two glands represent- 

 ing the missing median group. Cockerell (1896, b) , in his 

 description, says that there is but one median gland, but in 

 one specimen observed two glands were seen, as shown by the 

 figure. There are three pairs of well -developed lobes, decreas- 

 ing in size from the median line outwards, and trilobate in form. 

 The rudimentary fourth lobe is tolerably well developed and re- 

 sembles that oi pergandei. The marginal glands and plates are 

 the same in form and position as in proteus, pergandei, and zizy- 

 phus. The dorsal glands are the same in character and arrange- 

 ment as in pergandei and proteus.

Described from four mounted specimens, together with Cock- 

 erell's (1896, a and, 1896, //) descriptions at hand. 



theae var. euonymi Ckll. Plate XXVII, figure 2. 



This group differs from these only in having no representative 

 of the median group of circumgenital glands, as ascertained 

 from the study of four type specimens and reference to Cocker- 

 ell's (1897) original description.

viridis Full., syn. theae viridis Ckll. Plate XXVII, figure 3. 



Viridis has five groups of circumgenital glands according to 

 Cockerell (1896, a), the median group being represented by 

 from one to four glands. In the specimens studied, however, 

 it was impossible to determine whether the median group was 

 present or not, the specimens not being sufficiently well cleared, 

 and they are accordingly not shown in the figure. There are 

 three pairs of well-developed lobes, decreasing in size from the 

 median line outward. They are trilobate in form, and the tips 

 are usually more produced beyond the plates than in then. The 

 rudimentary fourth lobe is about the same in form and develop- 

 ment as in pergandei. The marginal glands are the same in 

 form and position as in thefr and pergandei. The plates are the 

 same in position as those in these, but are generally not quite so 

 long, allowing the lobes to project slightly beyond them, but 

 this characteristic is rather variable. The dorsal glands have
