224 Transactions. — Zoology. 



yellowish-brown, enclosed in a narrow elongated convex sac 

 of pure-white cotton so closely felted as to seem rather solid ; 

 and this sac is quite identical (except in size) with my type- 

 specimens of S. lazula from Europe. In size it is about twice 

 as large as the type, but I do not consider that as important. 

 The enclosed female is, before gestation, of the normal length, 

 about -Jin. ; but shrivels considerably at gestation. The an- 

 tennas have eight joints, of which the third and fourth are 

 the longest. Signoret makes the fourth and fifth longer than 

 the rest, but Mr. Newstead shows (Ent. Mo. Mag., May, 

 1892) that this is an error. The digitules of the claw are very 

 large and widely dilated. The margin of the body bears some 

 small spines, and the epidermis is covered with a great number 

 of tubular spinnerets. 



Hob. In Australia, on grass, Nevertire, New South Wales. 



At first sight I thought that this would turn out to be a 

 Dactylopid, probably D. herbicola or D. graminis, Mask. ; but 

 it is very clearly a Lecanid in all its characters. It would 

 have been easy for me to erect it into a new species on the 

 size of the sac and on some very minute differences which 

 may be detected in the antennas both of the adult and the 

 larva ; but I greatly prefer, wherever it is at all possible, to 

 avoid the multiplication of species. Perhaps a character men- 

 tioned by Signoret, and apparent also in this Australian form, 

 may also be conclusive as to the identity : it is that the sac 

 has a small orifice at one end, which is closed by the body of 

 the insect. 



Genus Pkosopophora, Douglas. Ent. Mo. Mag., Aug., 



1892, p. 207. 



Adult female covered with a test which is either waxy or 

 so closely felted as to appear almost homogeneous. Margin of 

 test without fringe. Antennae of not more than eight joints. 

 Anal tubercles present, but in the species observed very small. 

 Anogenital ring with more than eight hairs. Feet usually 

 atrophied. Mentum usually monomerous. There is generally 

 a small terminal orifice in the test. 



Male pupa covered with a test of similar material to that 

 of the female ; antennae of adult with ten joints. 



Larva exhibiting anal tubercles ; abdomen not cleft. 



In the foregoing diagnosis I have somewhat extended and 

 less definitely fixed some of the generic characters originally 

 laid down by Mr. Douglas, in order to attach to this genus 

 two Australian species which, with these alterations, will 

 sufficiently agree with it. I have been in great doubt as to 

 the genus to which they might belong, and, although in a few 

 respects they approach Planchonia, yet in others they differ 

 from it. If, on the other hand, I left Mr. Douglas's charac-
