THE ENTOMOLOGIST. 151 



July 27th : the common heather must be its food-plant ; I 

 never met with it except on small birch trees growing in the 

 heather. — R. S. Edlestoii ; December 9, 1864. 



90. How to Look for Notodonta CarmelUa. — From the 

 10th of April until the 21st I believe to be the best time ; I 

 never knew it taken sooner than the lOlh nor later than the 

 21st, having noticed its time of appearance in the North for 

 many years. It is generally found upon the trunk of the 

 birch tree or the oak, about mid-day, from four to six feet up 

 the stem. Although I have seen many specimens taken, I 

 never saw an imperfect one ; all seemed as if just emerged 

 from the pupa. — George Mawson ; Cockermoulh. 



91. How to Look for Cymatopliora ridens. — The same 

 dates apply to C. ridens : the 15th of April I have found the 

 most successful time for the search : it is taken upon the 

 trunk of the oak tree, mostly from one to four feet up : being 

 nearly the same colour as the bark it is very difficult to see, 

 and is often passed by. C. ridens requires some patience, as 

 every oak tree in the wood ought to be looked at. I have 

 looked from 7 until 12 o'clock without taking one specimen, 

 but by persevering in the search I have taken one dozen 

 before leaving the wood. The larva of this species may be 

 taken in June by carefully looking over the leaves of the oak 

 that are drawn together, as it draws two leaves together for 

 protection. — Id. 



92. How to Look for Notodonta irepida. — This species 

 may be taken from the middle of May to the middle of June, 

 in the same way as Cymatophora ridens. The larvaj may be 

 beaten from the oak about the end of June or the second 

 week in July. — Id. 



93. Lohopliora vlretata and L. poly comma ta. — These may 

 be taken the first week in May by carefully examining the 

 mountain ash. L. viretata is generally about four feet up the 

 stem, L. polycomraata generally getting close do«n to the 

 grass, and often concealed by it from view. 1 have often 

 tried, but never succeeded in getting the eggs of L. viretata.

94. Dying of Caterpillars. — All my larvae of Hadena rec- 

 tilinea died about three vveeks ago : I much regret I have 

 not succeeded in rearing it. I find those of a similar nature 

 very difficult to keep alive over winter, Aplecta tincta for
