The insect is a native of Japan. The present vogue in Japanese 

 plants must inevitably lead to the introduction of species from that 

 country, some of which may find, in the southern parts of England, 

 climatic conditions sufficiently like their natural home to permit of 

 their establishment here. Other instances of introductions from Japan 

 are noted below. 



PSEUDOCOCCUS PULVERARIUS NetVSt. 



Beneath the sheathing leaves of grass (Ayrostiss-p.). Camberley, 

 Septem])er. 



My examples differ slightly from the type, as described by 

 Newstead. The antennae and legs are proportionately longer and more 

 slender. Newstead describes and figures the anal lobes as being 

 " indicated by a single long hair surrounded by several spinnerets." 

 In addition to these structures, my specimens show two conical spines 

 and many shorter hairs on the anal lobes. There is also a pair of 

 similar spines on the lateral margin of the penultimate segment, and 

 an irregular transverse series of stout hairs across the venter of each 

 segment (see fig. 2-a). The whole derm is closely sprinkled with 

 minute trilocular poi-es, and many large circular pores (fig. 2-b) are 

 distributed over the venter of the abdomen, more particiilarly on the 

 posterior segments. 



Exainples taken at Budleigh Salterton (in 1896) appear to be 

 intermediate, the antennae and limbs being comparatively short and 

 stout, while the anal segments show the same characters as the 

 Camberley specimens. 



PsEUDOCOCCUS SPHAGNI nOV. 



Adult female pmkish (in alcohol). Form elongate oval : length approxi- 

 mately two and a half times the breadth. Anal lobes pronounced, each with 

 a longish terminal seta, a second one of rather more than half the length of 

 the fii'st, and several very miich shorter (see fig. 3-a). Antenna (fig. 3-b) 

 normally 8-jointed, the Sth always by far the longest ; 1st joint large and 

 stout, length equal to breadth, approximately as long as the 2nd which is twice 

 as long as it is broad ; 3rd equal to or only slightly shorter than 2nd ; 4th, Sth, 

 6th, and 7th shorter and approximately equal ; 2nd and 3rd joints cylindrical, 

 4th to 7th fusiform. There are, in some individvials, indications of a sub-division 

 of the Sth joint (fig. 3-c). Eyes somewhat prominent. Mentvim ratlier short, 

 scarcely longer than broad. Limbs moderately large ; tarsus half length of 

 tibia ; ungual digitules slender knobbed hairs, tarsal digitules apparently 

 obsolete. Anal ring with six longish stout setae. The usual glandular pits on 

 cephalo-thorax and post-abdomen are large but rather inconspicuous. Derm
