42 INSECTS NOXIOUS TO AGRICULTURE. 



somewhat prominent lobes, with two others much smaller not in 

 close proximity; edge of the body jagged, with curvilinear 

 incisions, amongst which and between the lobes are a number of 

 serrated pointed hairs, as in A. nerii. Four groups of spinnerets : 

 lower pair with four to six orifices ; upper, with six to ten. These 

 groups seem surrounded by a narrow line as if enclosed in a 

 chamber : the same appearance is presented (according to a figure 

 of Mr. Comstock's) in A. nerii. There are many single spin- 

 nerets. 



Adult male of normal form, with aiitennse of ten joints, of 

 which the seventh, eighth, and ninth are the longest. The 

 haltere has a somewhat long peduncle. The abdominal spike is 

 rather long, and springs from a large tubercle. 



Habitat On Carpodctus serratus and Vitex littoralis (puriri), 

 Wellington. The puparia are so like in colour to the bark that 

 it is difficult to detect them. 



This insect is evidently closely allied to A. nerii, but differs 

 in the abdominal lobes of the female and in the antennas of the 

 male; its male puparium is also much longer, and that of the 

 female more convex, than in that species.

(Plate IV., Fig. 3.) 



Female puparium really dirty-white, but seeming yellowish- 

 brown, from the colour of the insect beneath ; sometimes dark- 

 brown ; circular, flat; diameter, about yjin. 



Male puparium much smaller, rather oval. 



Adult female yellow, becoming brown at last ; peg - top 

 shaped, but the abdominal segment is comparatively so small 

 and is so much overlapped by the others that the insect looks 

 almost globular; length, about j^g-in. Abdomen ending in six 

 lobes (of which the two median are the largest) , and several scaly 

 hairs. No groups of spinnerets. 



* The author has not been able to find the original description of Genna- 

 dius, which appears to have been contained in a report to the Minister for 

 Agriculture in Greece. Dr. Signoret states that there is a reference to it ia
