Maskell. — On Coccidae. 405^ 



This species, in the wrinkled abdomen and the transverse 

 markings, approaches both to S. hamhusce, Mask., 1892 (Sand- 

 wich Islands), and to S. melaleucce, Mask., 1893 (Austraha) ; 

 but it is very clearly distinct from both. The broad and con- 

 spicuous chitinous bands are a quite distinctive character. 



Genus Iceeya. 

 Icerya nudata, sp. nov. Plate XXIII., figs. 1-6. 



Adult female yellowish-red in the anterior regions and 

 brick-red on the abdomen ; covered with thin white meal, 

 but not forming any ovisac. Body very thick, with a convex 

 •dorsum and swollen ventral region ; the dorsal and ventral 

 portions are separated by a lateral ridge. Antennse of ten 

 joints, of which the last, the first, and the third are the 

 longest, then the second and fourth, the rest shorter and 

 equal ; a few hairs on all the joints, and on the tenth are four 

 much longer than the others. Feet black and rather strong; 

 all the joints, coxa, trochanter, femur, tibia, and tarsus bear 

 ■on the inner side numerous rather strong spines ; the tarsal 

 <digitules are short fine hairs, digitules of the claw represented 

 by short thick bristles. The epidermis is covered with many 

 very fine short hairs interspersed with very minute circular 

 multilocular orifices, and along the lateral ridge there are also 

 many rather larger ones ; also on this ridge are many rather 

 longer hairs, which are most numerous at the abdominal 

 extremity. The length of the insect is about i-in., the height 

 -at gestation about \\n. 



This insect is viviparous, and a number of larvae can be 

 found within the body, so that an ovisac is not required. 



Larva dark-red, the feet and antennae black. The form is 

 normal of the genus, elliptical, slightly tapering ; length about 

 Jgin. xAntennaB of sis joints, the last of which is about as 

 long as the third, fourth, and fifth together; it is regularly 

 clavate, without any basal swelling or median constriction, 

 and bears four very long hairs. The abdomen ends with the 

 usual six small tubercles, from which spring very long setae, 

 almost as long as the body. The whole margin also bears 

 numerous setae, of which those on the anterior thorax are the 

 longest, diminishing gradually posteriorly except the pair just 

 anterior to the terminal six, which are as long as those on the 

 thorax. Epidermis bearing circular multilocular orifices which 

 are disposed in longitudinal rows ; from these is produced 

 ■some white cotton, usually visible in patches on the dorsum. 

 Feet presenting no special features. 



Female of the second stage, and male, unknown. 



Hah. In Australia, on Cosmos, Verbena, &c. Mr. OUiff 

 -sent me specimens from Sydney, stating that the insects were 

 •" said to be doing very considerable injury."
