Very few parasitic or beneficial Hymenoptera were trapped at any 
time and hence this order is omitted. 
Table XIII can best be reviewed by taking up the orders seriatim. 
Lepidoptera (Moths). — The only species of any considerable economic 
importance in the South is the Cabbage Plutella (Plutella cruciferarum). 
Experiments 3 and 4 were both located near a gardener's cabbage 
field. Its significance in this connection lies in the suggestion that 
gardeners growing cabbages extensively and troubled with this pest 
might resort to lam]) trapping with advantage. 
Coleoptera (Beetles). — Some of the large and well-known predaceous 
beetles were captured together with hundreds of many of the smaller 
species. Of the beneficial ladybird family a few specimens were 
trapped at various intervals. But this loss of beneficial insects is in 
part counterbalanced by the capture of several injurious species none of 
which, however, except the white grnb beetles, Lachnosterna longitar- 
sus and Cyclocephala immaculata were caught in great numbers. The 
last two species and a species of the wireworm beetles Monocrepidius 
vespertinus were caught by hundreds and may be considered a profit- 
able catch. Several species of injurious weevils and flea beetles were 
commonly trapped though not in great numbers. Following is a se- 
lected list of some of the beneficial and injurious beetles which were 
quite constantly trapped during the progress of the experiments. 
Xone of these were captured in great numbers. For the determina- 
tions of the species I am indebted to Mr. E. A. Schwarz of this Division.
