Aonidiella bromiUae (Newst.), Leonard!; Gen. e sp. 

 di Diaspiti. Estratto da. Hi vista di Patoloiria 

 Vegetale, 1897 [VI], 1900 [VIII]. 



Puparium of adult female (PI. Ill, figs. 1 3), high 

 convex, usually pyriform, narrowed, and attenuated 

 posteriorly with the cephalic margin widely rounded. 

 In some instances the posterior extremity of the scale 

 is slightly reflex ed. due, apparently, to its position upon 

 the food-plant. The rarer Forms of the scale are widely 

 ovate, or almost circular (PI. Ill, fig. 1); but all are 

 narrowed posteriorly. Colour varying From pale 

 oclireous to dark ochreous brown, or blackish In-own. 

 Kxuviae at the larger end of the BCale, toward> the 

 cephalic margin, shining black; first secret ionary 

 covering convex, thin, smooth, and grey, or ochrrous 

 grey, but rarely present in the old adults; second 

 secretionary covering convex, of nearly the same 

 colour as the scale, and is present in all the examples 

 before me. Ventral surface piceous. or madder brown; 

 faintly punctate; and has a thin giv\ i>h. mealy de- 

 posit; margin narrowly pale ochreous. Vent ral scale 

 complete, very thick ; almost invariably breaking away 

 in a circular or operculate form, remaining attached to 

 the food-plant, and exposing the female within the 

 scale. That portion which encloses the narrow pos- 

 terior extremity usually remains intact ; forming a 

 somewhat flat, horn-shaped cavitv and a receptacle for 

 the eggs (PI. Ill, fig. 2). 



Long. 2 2'25 mm. 



Scale of the immature female (PI. Ill, fig. '*>) elongate 

 or circular; colour a little brighter than those of the 

 adults; under side dark castaneous or madder In-own 

 and shining. Kxuvi;v central, are usually piceous.
