158 DIASPIS BROMELLE. 



each one is succeeded by a long projecting pore, and 

 there is an additional fourth pore which is much the 

 largest, has a pointed upturned apex, and is placed at 

 or near the centre of the margin. The spines are 

 small, and the first pair placed between the median 

 lobes. 



Puparium of the male closely resembles that of D. 

 boisduvalii in having a number of woolly filaments 

 attached to it, but they are much less abundant, and 

 the larval exuviae are of darker colour. 



Long. '75 1 mm. 



Male (PI. XIII, fig. 6) orange-yellow ; apodema 

 brightest ; legs and antennae paler ; wings pale hyaline. 

 Eyes and ocelli black. Antennas of ten joints thickly 

 set with long stiff hairs ; apical joint with central hair 

 faintly clubbed. Legs ordinary ; tibiae and tarsi with 

 long hairs ; digitules and claw ordinary. 



Larva short ovate ; pale yellow. 



Ova pale translucent yellow or colourless, elongate, 

 and sometimes slightly curved. 



Habitat. Curtis first called attention to this species 

 in the ' Gardeners' Chronicle ' for 1841, and says " the 

 pine-apple scale is often a great pest. . . On pulling 

 off a radial leaf ... I found considerable numbers on 

 the inside of the white part, which was tender and 

 afforded them shelter." The author makes no mention 

 of the locality ; but there can be no doubt the species 

 had well established itself in this country at the time 

 of his communication. 



During my own experience in the cultivation of the 

 pine-apple I never met with the insect, and doubt if it 

 can be considered a general pest in this country. The 

 examples for figuring were obtained from imported 

 pine-apples offered for sale in Chester. They oc- 

 curred chiefly on the green unripe side of the fruit, 

 and were often partly hidden in the deep sutures ; fre- 

 quently too they were quite concealed within the peri- 

 anth, and there it was the males abounded. It is 

 evidently a hardy species ; for although exposed for
