breed in the county, but I am unable to say whether it is univer¬ 
sally common. I have not seen any noteworthy variation, either 
in the colour of the plumage or the eggs. The tree creeper

everywhere in the county.

HINTS FOR THE MONTH. 
LEPIDOPTERA. 
Visit the sallows forthetaeniocampae and other moths. Severa 
larvae feed on the catkins of the willow and it is a good plan to 
collect a few and put them in a bandbox. 
Scotch entomologists should look out for Fidonia carbonaria and 
Eupithecia helveticaria. Eupithecia saiyrata , irriguata , denolata , 
abbreviate 7, and pumilata , appear in April, also Lobophora lobulata , 
Anticlea derivata , Scotosia dub it at a, Ceropacha ridens , Cucullia verbasci 
(end of month) Phceodes tetraquetana and immundana.

COLEOPTERA. 
The sweep net will come into use this month and the student, 
if he wishes to add to his collection, should make good use of it, 
from now until the end of the season ; everywhere where there is 
herbage the net can be used with, generally, very good results : 
the grassy sides in woods, lanes on the outskirts of woods where 
there is plenty of rank herbage, marshy places where there are 
reeds and rushes, are generally most productive. The umbrella
