considerable numbers were present. Tlie body of the female (Ix^neath 

 the waxy coverlni>') is of an orange-yellow colour. 



Winged males hatched out within the next few days. They are 

 very minute and delicate ; of a hone_v-yellow colour, with black ocelli ; 

 the body, wings, and limbs are dusted with white powdery matter ; there 

 is a ])air of long, white, waxy tilamcnts at the caudal extremity. 



Subsccpiently, in December, this same species was found somewhat 

 abimdantly in the Palm House at the Royal Botanic G-ardens, Kew, 

 upon Cocos, Kentiopsis, and Sahal. Examples of the adult females, 

 taken from sheltered ]iositions, have a ver\' characteristic appearance 

 which (in addition to the unusual colour) makes them easily distin- 

 guishable from any other s])ecies found in the British Isles. Later — 

 especially after ovi[)()sition — the mai'ginal appendages become disarranged 

 and confused, and the dorsal processes are either lost by abrasion or 

 obscured by the presence of additional secretionary mattei'. 



In fresh, undamaged examples there are distinct marginal, elorso- 

 hiteral ami medio-dorsal series of waxy ])rocesses (see fig. 1, <i). The 

 marginal series contains 124 processes (12 on each side), of which those 

 on the thoracic area (4 on each side) are confluent and broader than the 

 remainder; they are followed, on eacli side, by 4 rather longer taiiering 

 pi-ocesses and 4 shorter cylindrical processes. The dorso-lateral sei-ies 

 consists of a large conical anterior ])rocess, G small (often scarcely dis- 

 tinguishable) conical jujints on each side, and a large conical process 

 innuediately above the anal orifice. The medio-dorsal series contains a 

 single ver^' stout antero-niedian process, a pair of similar processes across 

 tlie middle of the dorsiun, and a single postero-median process. A pair 

 of narrow, white, ligulate Hlaments ]irojects from the anal orilice. 



The normal number of antennal joints aj)pears to be seven (fig. 1, Z»), 

 though ]Maskell states that they may be of either seven or eight joints, 

 '^i'lie only variation in my exani]»les is in the other direetion, tlio numlier 

 being occasionally reduced to six by a more or less complete fusion of tjie 

 3rd and 4th joints (see fig. 1, c). 



This very distinct species is now recorded from the British Isles for 

 the first time, Init it has probably been established in the i)lant-houses at 

 Kew for some A'cars.

 while sweeping for Cultoptcra, at Goring Woods, on .July 2Sth.
