This species, in the puparium, resembles F. stricta, Mask., 

 but the absence of abdominal lobes in the adult separates it 

 entirely. 



Section LE CANINE. 

 Genus Inglisia. 

 Inglisia fossilis, sp. nov. Plate XX., figs. 1-4. 



Test of adult female glassy, extremely brittle, yellowish or 

 brownish-yellow, elevated in a double cone whose apices are 

 slightly divergent, the bases attached at one side, conspicu- 

 ously marked with radiating striae composed of rows of air- 

 cells. From one apes to the other runs a deep narrow groove 

 closed at the bottom with striated secretion, so that the insect 

 cannot be seen within. In several instances there is only a 

 single cone, and in these there is no groove, the cone being 

 closed at the apex. At the base of the test there is a frag- 

 mentary small fringe, but this is often broken off. The base 

 of the test has an average length of about ^in., with a width 

 of |in., and a height of ^in. There is much black fungus ac- 

 companying the insects. 



Test of male pupa not certainly observed ; probably small, 

 white, narrow, glassy. 



Adult female dark-glossy-brown, conical, filling the test but 

 shrivelling at gestation. The margin is slightly flattened, 

 with usually a somewhat wavy outline. Antennae and feet 

 absent. Mentum doubtfully dimerous. Abdominal cleft 

 rather wide and shallow ; lobes normal ; anogenital ring with 

 several hairs, and above it a broad chitinous band nearly sur- 

 rounding it. The margin of the body bears some very minute 

 and inconspicuous conical spines, and there is a single median 

 dorsal longitudinal row of small circular spinnerets. 



Second female stage not observed. 



Larva red or brownish-red, flattish, elliptical; length, 

 about ^o™- Antennae of six short thick subequal joints. 

 Feet with the tibia slightly longer than the tarsus ; the four 

 digitules are long fine hairs. Margin bearing some small 

 conical spines. Abdominal cleft small, lobes large, terminal 

 setae long. 



Adult male unknown. 



Hab. In Western Australia, on^i cacm, sp. My specimens 

 were sent by Mr. Lea, from the Darling Eanges. 



This species is allied to I. foraminifer, Mask., 1892, but 

 differs in the form of the test, in the absence of feet and 

 antennae, and in other particulars. It is viviparous, the 

 female being usually full of larvae. The length of the tibia in 

 the larva is an exceptional character. The species is a large 

 and handsome one. 



The double cone of I. fossilis makes it approach in outward
