The spines or hairs are not very conspicuous, and are situated as seems most 

 usual with the Aspidioti, i. e., one at the base, rather laterally of each of the lobes, 

 and there are sometimes to be seen one minute hair about a quarter and another 

 about half-way between the apex of the last and the commencement of the penulti- 

 mate segment. 



The plates are very small, and are not always visible, but there seem to be two 

 simple plates between the median lobes, and two similar ones between the first and 

 second lobes, as well as two anterior to the third rudimentary lobe. 



The male scale has already been well described by Mr. Douglas {op. cit.). 



The male insect measures about '8 mm. from front of head to tip of wings, when 

 the latter are lying incumbent. It is of a yellow colour, mottled with orange-brown. 

 Antennae elongate, pubescent, 10 jointed. The basal and 2nd joint short, the 3rd, 

 4th, 5th, 6th and 7th are the longest and are equal, the 8th, 9th and 10 being 

 shorter and sub-equal, the last joint suddenly constricted at the tip and terminating 

 with a hair. Wings white ; one branched nervure. 



Thoracic transverse band very dark, almost black. Usual balancers, terminated 

 with a hooked bristle. Exserted genital organ about half the length of the body.

Note on Orthezia insignis {cf., p. 169 ante). — From the Botanic Grardens, 

 Cambridge, Mr. R. Irwin Lynch, the Curator, has had the goodness to send me living 

 examples of this insect on Eranthemum nervosum, a plant of the same Natural Order 

 as Strohilanthes {AcanthacecB) , on which I had it from Kew, and Mr. Lynch kindly 

 supplies the following information. " No doubt the insect came from Kew, where I 

 knew it years ago, but certainly it did not come ixpon the Eranthemum. It is numerous 

 enough on a specimen of this plant, and I think it does about as much harm as a 

 mealy bug. I believe I have seen the insect on other Acanthaceae, but not on a plant 

 of any other Order." In a note on this species by Mr. Edward T. Browne, published 

 in the " Journal of the Quekett Microscopical Club," Ser. ii. Vol. iii, No. 20, Dec, 

 1887, he states that at the Royal Gardens, Kew, " the insects have been gradually 

 spreading, in spite of the measures taken to annihilate them : now they may be found 

 on Scutellaria and other foreign plants in an adjoining house." 



On the two small terminal shoots of the Eranthemum sent by Mr. Lynch were 

 several examples of the adult female fixed by the rostrum immersed to its base in 

 the stem ; a few ? without marsupium wandering about ; and a great many very 

 small larvae, some of them just hatched, all the very miniatures of their mothers 

 before the development of the postnuptial marsupium ; these were stationary on 

 and sucking the stem. The motto of the Horticultural Society " Alienis mensihus 

 astas " is as applicable to these insects as to the exotic plants on which they feed, 

 for now, in our mid winter, under the fostering influence of artificial warmth, they 

 are as lively as othei-s of their race were in summer time. — J. W. Dougias, 8,
