5. Species with only a simple ring at the end of the abdomen : 

 antenniB with 11 joints in the adult 2, and 10 in the S : — Mono- 

 phleharia. 



Subdivision Kermesaria.

This group has been formed for the genus Kermes^ which connects 

 the Coccina with the Lecanina. At j&rst sight the insect hardly ap- 

 pears to differ from the sixth group of the genus Lecanium (p. 281), 

 but is differentiated thus : — Body globular more or less complete or 

 slightly truncate : in the larval state the presence of a more than one- 

 jointed under-lip, the absence of the abdominal lobes or plates and the 

 presence of more or less marked tubercles at the extremity, distinguish 

 them. In the adult state, the antennao and feet still remain almost 

 normal, but in some species, which have reached the last stage of their 

 life and have secreted their corneous envelope, the antennae are some- 

 times deformed and the feet are sometimes absent, and the abdominal 

 lobes resemble those of Lecanium. The species of the genus Kermes 

 hitherto recorded have been found in Europe and the United States. 



Subdivision Acanthococcaria. 

 Acanthococcites, Sign., A. S. E. F. (5 ser.) v, p. 16 (1875). 



This group contains those genera in which the species have an 

 elongate form more or less pubescent, but much less so than in Dacty- 

 lopius : antennae 6 — 7-jointed ; an emargination more or less visible 

 between the lobes of the extremity of the abdomen and these lobes with 

 5 — 6 hairs, of which one is very long. In the larval state all are the 

 same and have on the lateral margins a fringe of spiny hairs, and in 

 some genera on the median line also. The following gives Signoret's 

 table of the genera [1. c. p. 16]. 



1. Adult ? without legs or antennae : rostrum arising from a 

 curious tubercle or protuberance on the head : body resting on a cot- 

 tony mass which extends beyond and covers its margins. The (? un- 

 dergoes its changes in a small cottony envelope : antennse 6- jointed : 

 wings with a very small lobe near their insertion : halteres with a 

 single bristle : head with 4 — 6 ocelli. Larva with 6- jointed antennae 

 in ? , 7-jointed in d : adult has the dorsum covered with a transparent 

 waxy and knobbed secretion : — Nidularia, Targ. [Sign., 1. c. p. 17]. 



2. Adult ? with legs and antennas : rostrum not arising fron^ 

 the usual place between the first pair of feet, without a tubercle : body
