Colorado Beetle.

It is probable that they may go on appearing for another two weeks, 
but I think it well to have a watch kept over the plot for at least a 
month. That a brood may appear over some time we may judge from the 
fact that eggs and larvae in all stages were found last August at the same 
time, although it is probable that the first brood would hatch out about 
the same time. 
Recommendations. 
1. Constant supervision and hand-picking adults and ova on infested 
plot in the docks for one month. 
2. Very careful examination of the potato plots along the railway line 
just outside the dock property. 
3. Clearing off the rough herbage in close proximity to the infested 
plot. (It would be as well not to burn this near ; smoke very often makes 
insects fly when they otherwise would be sedentary.) 
4. A 11 examination of all potato fields and plots within a three-mile 
radius of the dockyard plot. This had best be made twice ; once as soon 
as possible, and again about the 21st of June. 
A visit ought to be paid now as well as later, because some of the 
beetles may have flown away last year and hibernated, and like those kept 
at Wye, have appeared during the early part of May and commenced to 
breed. If this has happened the larvae should be quite large. 
5. It would be well to have the leaflet on this pest sent to all potato 
growers on both sides of the river to distribute to their men. 
COLORADO BEETLE ENQUIRY. 
(Board of Agriculture.) 
Insects sent as Colorado Beetles. 
A number of insects were sent to the Board of Agriculture as 
Colorado Beetles from different localities ; it is a matter of interest to 
note the great variety of creatures sent— none being the pest in 
question. The specimens are as follows : — 
No. 1. 
No. 2. 
No. 3. ) The Cockchafer ( Melolontha vulgaris, Fabr.). 
No. 4. 
No. 5. / 
No. 6. Chrysomela mctrginalis, Duft. 
No. 7. Bibio hortulanus, Linn, (a fly). 
Ro. 8. Larvae of one of the Chrysomelidcc (Colorado Beetle family) 
of the genus Timarchcc. 
No. 9. Burying Beetle ( Necrophorus sp.). 
No. 10. The Cockchafer (Af. vulgaris, Fabr.).
