deposit proceeds, somewhat flattened, and with lines across 

 showing a division into rings, that is, segmented, each seg- 

 ment having on each side two or three strong spines. Abdo- 

 men ending in two large lobes, with two others much smaller 

 on each side ; middle lobes trifoliated. After depositing her 

 eggs she dies, and may be found shrivelled inside the scale. 



Male of Mi/tilasjiis 2}0)noriiiii, much maguified. 



The male (see figure)* differs entirely from the female in 

 being active, having six long legs, and a pair of wings ; the 

 colour is described by Prof. C. V. Eiley as a "translucent 

 corneous grey," with some portions of the fore bod}^ darker,, 

 and the legs lighter. 



In the United States there is only one yearly brood in the 

 northern parts, but two in the warmer parts ; with us, so far 

 as I am aware, there is only one generation in the course of 

 the year, of which the young insects appear in May, when 

 they creep out from under the old dead scales and begin 

 attack. 



Prevention and Eemedies. — Scale may be removed at any 

 time of the year, but the best season for destroying it or 

 applying dressings is in spring, so as to clear it away before 

 the young insects which creep out in May, as above mentioned, 

 have spread themselves abroad. 



It may be removed by thoroughly moistening the surface of 

 the infested bark with lathers of any kind of soap (or any 

 dressing that may be preferred), and then scraping the surface 

 with a blunt knife, or rubbing it with pieces of coarse canvas, 

 or well brushing it, so as to clear ofl' the scale without hurting 

 the bark. 



Scraping with a blunt knife is a good plan, as in this wa}' 

 the scales, moss, and everything on the surface are mixed up 

 in a plaster with the soapy lather, and got thoroughly rid of 

 together ; if brushing is preferred, good drenchings of soap 

 and water, or of dressings poisonous to the scale, should be
