the same form and arrangement as those in the^r;, pergandei, and 

 proteus. 



Food-plant : Thex viridis has been found on Ilex peduncuJosa 

 in Japan, and viridis on Pittosporum in West Australia. 



Described from three specimens of viridis and eight specimens 

 of theR- viridis, four of which are type specimens, together with 

 Cockerell's (1896, a, and 1896, b) original descriptions and 

 drawings. 



proteus var. crotonis Dougl. Plate XXVIII, figure 1. 



Crotonis has four groups of circumgenital glands. There are 

 three pairs of well-developed lobes, trilobate in form, and de- 

 creasing in size from the median line outwards. The presence 

 of the rudimentary fourth lobe is very variable. The marginal 

 glands, plates and dorsal glands are as in. proteus and per gandei. 



Food-plant : Croton. Habitat : Antigua, .Jamaica, Great 

 Britain, and in Massachusetts in botanical gardens. 



Described from five mounted specimens, with descriptions by 

 Newstead (1901), Cockerell (1892, and 1899, a). 



DISCUSSION OF SYNONYMY. 



The above so-called species described under pro^evs have been 

 determined synonymous on the basis of the similarity of the 

 arrangement of the dorsal glands. Although described as sep- 

 arate species, their validity has never been finally established. 

 The distinguishing characteristics given by the various authori- 

 ties have in every case proved inconstant or not of specific 

 value, as will be brought out in the following discussion of the 

 synonymy of these species with proteu>i. 



Comstock (1883) differentiates proteus and pergandei on the 

 basis of the shape of the scale of the female, given as circular 

 in pergandei and elongated in j^fotens, but in 1881, in his original 

 description of pergandei, he says that the scale of the female 

 varies, being sometimes nearly circular but usually somewhat 

 elongated. Hunter (1900 or 1904) says he finds no steadfast 

 distinction either in shape or color of the female scale, finding 

 circular scales among proteus and elongated scales among per- 

 gandei. Newstead (1901) says that the puparium of the female 

 oi pergandeiis very variable, often being circular but sometimes 

 elongate. It is accordingly evident that there has been no spe- 

 cific distinction found in the scale.
