through the nearly transparent test, made the latter look 

 almost black. Length of test about T V n - 



Adult male dark-orange or red in colour ; length, exclusive 

 of spike, about ^yin. Antennae of ten joints. Dorsal eyes four, 

 ventral eyes two, ocelli two. Wings brightly iridescent, with 

 strong red nervures. Abdominal spike rather thick at the 

 base, slightly curved, and nearly as long as the abdomen.

This insect belongs to Signoret's second series of the genus, 

 being convex, with (at least, in the second stage) a dorsal 

 longitudinal carina. I cannot identify it with any known 

 species. The male, with its bright wings and their red 

 nervures, is an elegant little insect. 



Genus Pulvixaeia, Targioni. 

 Pulvinaria dodonsese, sp. nov. Plate XIII. , figs. 8, 9. 



Adult female reddish-brown, darkening with age. Before 

 gestation the form is regularly elliptical, fiattish or slightly 

 convex, and has the appearance of a full-grown Lecanium ; as 

 the white cottony ovisac is formed the insect shrivels, becoming 

 corrugated and irregular in outline, and at the last appears 

 only as a small brown speck at the end of the white cottony 

 sac. The size therefore varies, some individuals observed 

 before gestation reaching ^in., while the females after gesta- 

 tion average only ^yin. The ovisac averages about ^in. in 

 length, and is of the normal subcylindrical form. Antennas 

 of eight joints, of which the third is the longest, the last 

 four the shortest and equal to each other. Feet rather 

 long and slender ; the tibia is about twice as long as the 

 tarsus, which is slightly curved ; the tibia is somewhat ex- 

 panded at its end ; lower digitules long and expanded, upper 

 pair fine hairs. There is a row of spiny hairs round the 

 margin of the body, set rather close together. Abdominal 

 cleft narrow ; lobes rather long ; anogenital ring with several 

 hairs. Mentum monomerous. Epidermis with great numbers 

 of spinneret-orifices, principally on the abdominal region. 



Female of the second stage regularly elliptical, very slightly 

 convex, smooth; colour greenish-yellow; length about J^in. 

 Antennae of six joints. Feet as in the adult. This stage is 

 frequently parasitized. 



Larva yellowish-brown ; fiattish, elliptical ; length about 

 ^in. Antennae of six joints, subequal except the last, which 

 is a little longer, and bears some hairs of which two are rather 

 long. Abdominal setae long. 



Male pupa covered with a white, glassy, elongated test, 

 with sides and ends sloping, and the top covered with a flat
