LECANIUM BITUBEECULATUM. 103 



yellow, with four broad transverse bands of yellow on 

 either side of the dorsum ; the latter has a central 

 raised keel or carina extending from the anal lobes to 

 the margin in front, and is of a transparent yellowish 

 colour, and somewhat glassy. The four channels 

 leading to the spiracles, strongly indicated above 

 by well-defined carinas, are situated on the two central 

 bands. Margin with a much interrupted fringe of 

 glassy material. Anal cleft well defined. 



Long, 1'50 2 mm. 



Male (fig. 9) dark or pale red, or coral-red ; apodema 

 and divisions of the thorax darker. Eyes and ocelli 

 black. Legs dusky yellow or reddish. Caudal fila- 

 ments very slender and more than twice the length of 

 the body. 



Male puparium normal, and very like that of L. 

 sapredz. I have found it invariably attached to the 

 leaves of the hawthorn. 



Ovum pale yellow. 



Habitat. On hawthorn (Cratsegus oxyacantlia). 

 Mr. Douglas (1. c.), who first recorded the species in 

 this country, says: "On February 15th last (1888) 

 Mr. E. Parfitt sent from Exeter one, and on March 

 20th the other of the two scales described above, 

 which he had just found on twigs of hawthorn in a 

 hedge ; this is the first time the species is known to 

 have been taken in Britain. On the 4th of April, on a 

 hawthorn hedge at Lee, within a space of two yards, I 

 found twenty-four scales of this species, always on 

 shoots of last year's growth, sometimes singly, at 

 others two or three close together, mostly at the 

 base of a thorn or bud, but they were localised, for 1 

 sought in vain for more in other parts of the 

 hedge." In July, 1895, I found a colony of this 

 species at Heacham, Norfolk, and succeeded in 

 rearing the hitherto unknown male. I have also found 

 it plentiful at St. Albans, Tring, and King's Langley, 

 Herts, and sparingly at Orpington, Kent, and 

 Brockworth, near Gloucester. I have received it
