3. Fiorinia stricta, sp. nov. 

 Figs. 5-9. 



Puparium very narrow, the length being about five times the width. 

 The second pellicle fills almost the whole of it, half of the first pellicle 

 appearing at the cephalic end, and a very narrow edge of secretion running 

 down the sides, which are almost straight and parallel. The diagram 

 (fig. 6) shows the arrangement. Length of puparium about ^inch : colour, 

 for the female, almost black ; for the male, white. 



The first pellicle shows the compressed cylindrical form of the head, 

 spoken of under the last insect, F. grossularice. Indeed, this appears to be 

 a character common to all the genus Fiorinia in this country, with the ex- 

 ception of F. minima. 



The second pellicle, which forms the puparium, appears to be entire 

 throughout almost all its length. But at the posterior end, as shown in 

 fig. 6, it is cut across by several transverse corrugations dividing it into 

 narrow segments ; and the edge, generally semicircular, is sharply serrated, 

 but the serrations are not so deep as in jP. minima. This pellicle is very 

 strong and hard, and by its dark colour makes the puparium altogether 

 look black. 



The adult female is very small in comparison with the second pellicle 

 (fig. 6). After gestation, indeed, it shrinks up at the cephalic end so as to 

 become difficult of detection. It has the general form of Mytilaspis, with 

 compressed cylindrical head. The lateral corrugations bear no spines. 

 The abdominal segment (fig. 5) is somewhat elongated, and the edge is 

 broken into a number of protruding, sharp-pointed lobes, giving it the 

 appearance of a comb. There are no median lobes like those of almost all 

 other Diaspidse. Spinnerets normal of the genus, the three upper groups * 

 joined in an arch. Length of adult female before gestation about -^ inch : 

 colour dark brown or purple. 



The male paparium is, in shape, similar to that of the female : but of 

 course, as there can be here no second pellicle, it is composed almost 

 altogether of fibrous secretion. Its colour, therefore, is white, with the 

 first pellicle, which is black, at the cephalic end. Length, about T X T 

 inch. 



The adult male has the normal form, generally, of the Diaspidas. The 

 antennse (fig. 7) have ten joints, of which the first two are very short, the 

 rest long, thin, hairy, and about equal to each other, except the last, which 

 is a little shorter and broader, being irregularly fusiform. Amongst the 

 hairs on this last joint is one a little longer than the rest and bearing a ter- 

 minal knob. Foot normal (fig. 8) ; the claw is very slender, and the four 

 knobbed digitules are fine hairs. There is a strong spine at the extremity
