82 THE ENTOMOLOGIST. 



Ceroplastes plumhaginis, n. sp. 

 Antigua; on Plumbago capensis (C. A. Barber). 



Egcf. — Elongate-oval, pale pink. 



Newly-liatclied larva. — Caudal filaments long, nearly as long as body, 

 curved, with the convexity outwards, so that they cross one another. Claw 

 with large curved digitules, and tarsus with the usual two clubbed hairs 

 rather strong and thick. The legs bear a few very strong bristles, the largest 

 being apparently on the trochanter. Segmentation distinct. Antennae with 

 last joint emitting some long hairs, the last of which is at least as long as 

 the whole antenna. 



The young larva of cirripediformis is said, by Comstock, to be " very 

 slender, dark brown," whereas this larva is yellowish, and broad, with about 

 the outline of Lecaniuyn hesperidum. Internal to each caudal filament is a 

 short hair or bristle ; these are called by Comstock, in his description of 

 C.floridensis, the bristles of the caudal lobes. 



Larva. — Has thirteen lateral tufts in all ; whereas cirripediformis is 

 stated by Comstock to have fifteen. 



Adult ? . — Much resembles cirripediformis in appearance, but is 

 unusually high. Length 4, lat. 3, alt. 3 mm. Colour much Hke cirripedi- 

 formis, summit with a light dorsal patch (the dorsal patch of larva) very 

 small, and surrounded by dark colour. This again broadly surrounded with 

 whitish, and outside this a dark reddish ring (in some specimens obsolete). 

 This dark ring is due to the thinness or absence of the wax at this point. 

 The lateral plates are distinct, and near their lower edges are some 

 conspicuous patches of chalky white secretion. There are two lateral plates 

 on each side, each with its central tubercle, and one at each end, making six 

 in all. However, the anal plate is evidently two joined together, as Comstock 

 remarks of cirripediformis. The pink eggs are conspicuous underneath the 

 female. 



This species, like others of the same group, lives upon the 

 twigs and branches, not upon the leaves. 



When the specimens arrived from Antigua, I found among 

 them a small Coccinellid beetle, which Mr. Schwarz has kindly 

 identified for me as Scymnus ochroderus var. cyanipennis, Muls. 

 No doubt it is predaceous upon the Ceroplastes. 



Ceroplastes denudatus, n. sp. 

 Antigua ; on Sour Sop {Anona muricata). Collected by Mr. 

 C. A. Barber. 



Abundant, clustered on the twigs like Lecanium Jiemisphoericum, which 

 it resembles closely. Very few on leaves, and these on the under side, 

 mostly at base. The size and shape of the scales are like L. hem,isphcericvmi, 

 and in age they become almost entirely bare of wax, and resemble in colour 

 the paler specimens of hemispJioericum. The length of a scale is one-eighth 

 of an inch. 



The old TiemispTicericum-Yiike scales are, however, seen to have at the 

 summit the elongate whitish patch of Ceroplastes, and some bright white 

 patches remain round the margin. The scales which have not lost the wax 

 are dull pinkish white, with the dorsal patch broadly margined with brown- 

 pink ; and the lateral plates, somewhat broader than long, with their central 

 white patches or knobs similarly margined. 



The species is allied to cirripediformis. It might be con- 

 founded with janeirensis, but it is smaller than that scale.
