to the inmates, and in one place they got on the railroad track, ren- 

 dering it slippery, so that trains had a hard time getting past. 

 Many caterpillars were collected and placed in a breeding cage. May 

 S, caterpillars were beginning to pupate ; May 24, moths were emerg- 

 ing rapidly ; May 27, females were depositing eggs. 



xVn interesting occurrence of injury to pecan trees was first 

 brought to our attention April 7, when we received a letter from 

 Monticello, Ga., stating that some insect w^as eating the buds and 

 leaves as fast as they appeared from a grove of pecans, which aver- 

 aged 10 to 12 feet high. Investigation brought out the fact that 

 the damage was caused by two species of Lachnosterna, namely, 

 inversa Horn and hirtiaila Knoch. The adults worked on the trees 

 mainly at night, eating the opening buds and entirely preventing 

 the foliage from developing. A method of jarring the trees at night 

 and capturing the beetles on a sheet was suggested as a remedy. 



Among the cotton insects several common forms have been present 

 this year, and at least one species not heretofore considered of impor- 

 tance in Georgia. 



The cotton caterpillar (Alahmna nrgillaeea Hbn.) was not as aban- 

 dant as usual, though present in a number of counties in middle and 

 southern Georgia. Its late appearance in considerable numbeis ren- 

 dered it of almost no consequence. 



The boUworm {IleUothis ohsoleta Fab.) was also rather unim- 

 portant this year, though w^e were expecting its appearance in con- 

 siderable numbers, because of the great amount of injury reported in 

 1904. Remedial measures were not necessary so far as we are aware. 



Lu/perodes lynmneus Cr. made its appearance in nine places in at 

 least six different counties in the period between June 20 and Jidv 5. 

 The counties in which it appeared were rather widely separated, 

 thus rendering the outbreak the more remarkal)le. The beetles ap- 

 peared in great numbers in all cases, feeding on the leaves, squares, 

 blooms, and young bolls of the cotton plants. Their favorite place 

 for feeding was in the opening blooms, from which they would eat 

 the entire center and sometimes the petals. At night they would 

 gather in solid masses on the under side of the leaves and in t!ie 

 squares. It was not uncommon to find as many as 100 on a single 

 leaf. Untold damage was reported, the letters received stating that 

 whole fields of 50 acres or more Avould be devoured in a few weeks if 

 the beetles were not checked. The rej^orts, of course, were sadly ex- 

 aggerated, but the excitement caused by the appearance of this beetle 

 was intense, while it lasted, and led us to investigate. "We found it 

 true that some plants were entirely destroyed and sometimes several 

 hundred in a spot badly injured. Just where the beetles came from 

 we could not tell. Paris green in dry and wet form was recommended 

 as a remedy and was used in a few places. It was our intention to
