Maskell. — On Coccidicla\ 29 



Taken iu coujuuction with the eight -jointed antenna figured 

 by Mr. Koebele, and also the absence from his figui-e of the 

 longitudinal dark stripes of the adult M. crawfordi, his state- 

 ment about the anal setae raises the question whether the in- 

 sects he saw may not have been immature. 



Genus Ccelostoma.. Maskell. 

 Coelostoma pilosiun, sp. nov. Plate \1I., figs. 1-10. 



Adult female dark-red in colour. At first naked ; then with 

 a thin covering of white meal, which gradually becomes 

 thicker and more solid, until it assumes the appearance of a 

 hard, granular shell, looking like a coating of lime : at ges- 

 tation this increases to a snow-wliite mass of closely-felted 

 cotton covering the insect and the eggs. Length of insect 

 variable, some specimens attaining a length of iin., shrivelling 

 at gestation. Form elliptical, convex, distinctly segmented. 

 Antennae of eleven sub-equal joints, each joint except the last 

 very slightly dilated towards the tip, the last joint ovate ; all 

 the joints bear hairs, and on the last are two stronger than 

 the rest. Feet strong and thick ; on the trochanter a long 

 seta ; all the joints bear several hairs, but there seems to be 

 no distinct comb of spines on the inner edge of the tibia and 

 tarsus ; the claw has a minute tooth. Upper digitules absent ; 

 lower pair fine hairs. Epidermis thickly covered with longish 

 hairs interspersed with small, simple, circular spinneret- 

 orifices. Anogenital ring simple : at the extremity of the 

 abdomen are two very small tubercles, with a shortish seta on 

 each. Eostrum and mentum entirely absent, being replaced 

 by a small orifice between the first pair of feet. 



Femu'e of second stage dark-red in colom-, covered partially 

 or wholly with a hard, white coating, like lime, which fre- 

 quently at last exhibits marginal tuberosities forming a kind 

 of thick fringe. Length variable, reaching sometimes ^in. 

 when extracted from the shell. Form elhptical, slightly 

 convex, segmented. x\ntennaD atrophied : .they may have six 

 or eight joints, but these are so confused that it is difficult to 

 determine the number ; at the tip are several spiny hairs. 

 Feet also atrophied, the joints appai'ently reduced to two, with 

 a very small hook-like claw at the end. Eostrum and mentum 

 very large : mentum conical, triarticulate. Epidermis very 

 thickly clothed with longish rather thick hairs, interspersed 

 with small, simple, circular spinneret-orifices. Anal extremity 

 not exhibiting a brown patch ; the anal ring simple, with the 

 tubular internal organ usual in the genus, and frequently a 

 long, slender, white, waxy filament. 



Larva red, active, naked or with thin white cotton ; ellip- 

 tical, flattish, segmented ; length about ^V^- Antennae of six
