170 AULACASPIS (DIASPIS) 



On the dorsum are three equidistant bands of short 

 tubular spinnerets, extending from the extreme margin, 

 and almost meeting at the centre, forming incomplete 

 arches. On each side the median line are four to six 

 long, slender, tubular spinnerets, which extend almost 

 to the vaginal opening, and are connected to a corre- 

 sponding number of dorsal pores opening in a longitu- 

 dinal series towards the margin. Median lobes very 

 long, widely divergent, but almost touch at the base ; 

 inner margin finely serrate, apex scarcely free ; second 

 pair of lobes divided and separated so as to appear as 

 two distinct lobes; the third pair are also separated, 

 laterally very broad but extremely short, and are often 

 completely hidden by two projecting dorsal pores. 

 Plates large and spine-like ; the first and second imme- 

 diately precede the median and second lobes, and there 

 are usually four others disposed along the margin. 

 Marginal tubular spinnerets usually number about 

 seven, but the connecting marginal pores do not project 

 far beyond the margin, and their apices are widely 

 rounded. There is a pair of spines between the 

 median lobes ; one on each surface of the outer lateral 

 margin of the median lobes, and a pair near the third 

 plate, and several beyond. 



Puparium of the male white ; strongly tricarinate, 

 central carina usually the strongest. Exuviae varying 

 from very pale yellow to brown. 



Long. 1 mm. 



The second- stage male resembles the young female ; 

 is of a bright orange-yellow colour. 



Pupa pale orange to orange-red. 



Male (PI. XIV, fig. 7) bright orange-red or orange- 

 crimson ; abdomen with a pale purplish tinge at the 

 sides ; legs and antennas paler ; wings hyaline. Eyes 

 and ocelli black. Antennae with long slender hairs ; 

 apex of apical joint with a long terminal clubbed hair, 

 a short, broad, angular spine, and two fine spine-like 

 processes opposite it (PI. XIV, figs. 8, 8 a) ; both the 

 position and number of the three latter vary consider-
