SCALE-INSECTS. 77 



Test of the male elongated-oval, convex, but wanting the 

 prominent horn of the female, glassy, white tinged with yel- 

 lowish-brown, composed of segments marked with conspicuous 

 striae. Length, -j^in. Fringe often present, but irregular ; 

 often absent. 



The adult female fills the test, shrivelling after gestation. 

 It exhibits the horn, or two horns, as in the test. Antennae of 

 seven joints, the third joint showing the false division noted in 

 other species of Lecanodiaspidae. Feet normal ; upper digitules 

 strong and thick, lower pair rather broad. Along the edge of 

 the body is a row of sharp lanceolate spines set closely together, 

 and the spiracular spines are long and conspicuous. A double 

 or triple row of minute circular spinnerets marks the divisions 

 corresponding to the segments of the test. Colour of the 

 insect greenish, turning brown after gestation. The abdominal 

 lobes are brown. 



In the second stage the female resembles generally the 

 adult ; but the antennae have six joints, and amongst the mar- 

 ginal spines are some very much larger than the rest. 



The young larva is flat and oval, and at the margin shows a 

 fringe of long glassy pointed tubes, springing from the mar- 

 ginal spines. 



The adult male is about ^in. in length (exclusive of the 

 wings), brownish or reddish-yellow in colour, the wings hyaline 

 and iridescent, with red nervures. Antennas of ten joints, on 

 the last of which are, amongst others, three long knobbed hairs. 

 Foot with a spine at the extremity of the tibia; digitules fine 

 hairs. At each side of the abdominal spike springs a strong 

 seta, from which extends a white cottony pencil, as long as the 

 body of the insect. The penis is a long soft cylindrical tube 

 covered with minute recurved spines. Thoracic band short and 

 narrow. 



Habitat On Elceocarpus dentatus (hinau), Leptospermum sco~ 

 parium (manuka) ; Wellington."* 



This is a handsome species : the colour and the horns of the 

 test are clear distinctions. 



* The male pupse may be found not unfrequently on other plants, such as 

 Coprosma, Pittospomm, &c.
