MtTILASPIS CEOTONIS, 11. sp. 



Found by Mr. J. J. Bowrey in his garden at Kingston, Jamaica. It lives on a 

 variegated Croton with narrow leaves. The twigs are more or less covered by the 

 scales, which are so exactly the colour of the bark, and so resemble the rugosities 

 natural to the plant, that notwithstanding their abundance, they are only detected 

 on close examination. 



The scale is about the shape and size of M. pomorum ; some show holes through 

 which a parasite has escaped. 



The very young larva is active, pale purplish with yellowish extremities. The 

 caudal filaments are about as long as the greatest diameter of the body, but they are 

 easily broken off. Between the tubercles, which bear the long filaments, are two 

 small but distinct tubercles, each bearing two very short bristles. Along the margin, 

 immediately external to the filament-bearing tubercle, is on each side a pair of 

 bristles of fair length. Beyond (anterior to) these is another shorter pair, and 

 further still two more pairs, which are very short and not conspicuous. On the sides 

 of the thoracic region are one or two short hairs. On the margin, anterior to each 

 antenna, is a blunt tubercle, and the anterior cephalic margin presents three pairs 

 of hairs, the middle pair strongest, the outermost pair rudimentary or almost 

 obsolete. The last joint of the antenna presents three or four short but strong hairs. 

 The general form of the larva is oval. The leg shows a strong claw apparently 

 without digitules, but the tarsus has stout clubbed hairs, longer than the claw. In 

 colour these larvae resemble those of M. Qloveri, as described by Comstock. 



The adult female, as usual in the genus, is elongate. The terminal portions are 

 yellow shading into orange. The lobes are much as in other members of the genus : 

 median lobes separate, well-developed, trilobed ; next pair bifid, and smaller ; third 

 pair practically obsolete, but two distinct notched projections beyond them. 



The really extraordinary character of the adult ? is in the spinous plates, which 

 are prolonged into long hairs, after the m&rmev oi Aspidiotus cAamffiropsis, as figured 

 by Signoret. This distinguishes the species at once, but with rough handling the 

 hairs are easily broken off, leaving an appearance like the ordinary spinous plates. 



Bright orange mites are common among the scales, and seem to prey upon them. 

 I found one mite inside a female scale, half concealed beneath the body of the 

 female ; another actually had hold of a larva. The anterior legs of these mites emit 

 two very long hairs, a character which may perhaps serve to distinguish them. 



Mttilaspis albus, n. sp. 



I found this in East Street, Kingston, in abundance on the stems of a roadside 

 weed. The plant is one of the Malvacece, low, shrubby, with a strong odour, yellow 

 flowers, and pubescent or velvety cordate practically entire leaves. Mr. Bowrey 

 tells me it is locally called " sage," but Grisebach applies that name to a different 

 plant, neither, of course, being the true English sage. 



The ? scale is about 24 mm. long, elongate, narrow, mytiliform, convex, sometimes 

 curved. The scales vary much, some being quite long and narrow, others broad. 

 Colour greyish-white, the exuviae, which are of the usual size, reddish-brown. Several 

 of the scales show holes where parasites have escaped. 



The adult female is elongate, mytiliform, narrow anteriorly, with three blunt 

 and wide lateral tubercles. Colour brown.
