1 have not soph tlip final stao-c of llic lai'va, in the life ; l)ut 

 examination of the exuviae, after tliev have been expanded bv niaeera- 

 tioii, shows that it must be very similar in appearance to the adult 

 female, though eonsidei-ably smaller. It has the sanie nmnl)er of 

 antennal joints, but the individual segments are shorter and broadei'. 

 There is a eonspienous long seta Immediately anterior to the insertion 

 of eaeh limb. Average length I'o mm. 



The female nymph has still evaded diseovery. 



The adult females oceur abundantly on (and under) individual 

 Bireh trees, but are distinetly localized, emerging fi-om the same trees 

 year after year. As noted in a previous article (Ent. Mo. Mag., Dec. 

 1917, p. 26S), the greatei- number of the insects desert the stems before 

 oviposition and take shelter amongst rubbish on the ground. I have 

 found many ovisacs inside dead and f)roken stalks of bracken. 



It will be observed that I have hei-e reverted to Nassonow's generic 

 name (Sfeii/f/elia) for the species. I still think that, eventually, it 

 may have to be placed in the earlier genus Kuiranid \ but the question 

 cannot be decided until the male of the type species — K. qverciis — has 

 been made known. 



The male characters of the ]ir(>sent species would seem to constitute 

 a connecting link between Margnrod iiiar and the Psfudococcinar. It 

 may, perhaps, be necessary to erect a new subgenus of the former family 

 to contun the genera Sfeingflin and Sfomococcvs — characterized by the 

 sim])ler structure of the males. 



JEriococciis grceni and E. insigms. 



The white or pale ochreous sacs of these two species, both of 

 which occur upon grasses, have been considered, hitherto, to be indis- 

 tinguishalile. IVewstead, in his description of ^yr*?;?/, remarks : "ovisac 

 of female not separable from that of JE. insignis.^' But Newstead had, 

 at that time, seen a single example only oi green?'. Both species occur 

 together, at Camberley, in some abundance, and I have been able to 

 compare long sei'ies of their ovisacs. As a result, I am now able to 

 separate the two species, from the characters of the ovisacs alone, with- 

 out reference to the contained insects. A fresh, undamaged ovisac of 

 Eriococciif: greeui has, invariably, a number of erect, glassy filaments 

 standing out from the general matted surface of the sac (fig. 3, a^. 

 Even in old, worn specimens a few of these erect filaments are sure to 

 persist, especially above the extremities. The ovisac of E. inftic/nis
