plant the larvae had evidently gathered beneath the calyx for 

 protection during pupation, the principal injury being done to 

 the leaves. In the poha the damage was very serious, since the 

 injury to the stem precluded blossoming and consequent forma- 

 tion of fruit. 



NATURAL ENEMIES. 



From the poha stems received from Kona a specimen of 

 Chclonus blackbiinii, Cam., was bred. This is a good sized, four- 

 winged fly — i. e., good sized for an internal parasite — which can- 

 not be mistaken because of the strong contrast in color between 

 the apical segments of the abdomen which are pale yellow, the 

 rest of the insect being black. From the tomato and Qgg plant 

 worms another parasite was bred; this was named by Dr. Ash- 

 mead, through the kindness of the United States Bureau of 

 Entomology, as Linuicriiuii polymcsiale, Cam. This insect Air. 

 Perkins tells me is more or less common over all these islands 

 and doubtless does a good deal of good. It is evidently, how- 

 ever, not sufficient to materially check damage by the splitworm 

 since in either instance the number of moths bred exceeded many 

 times that of the parasite. 



REMEDIES. 



Clean culture, with all it implies, is doubtless the very best 

 means we have at present for combating this insect. By clean 

 culture we mean the eradication of all foreign, especially allied 

 plants, from between those cultivated. The removal of all rub- 

 bish from the vicinity of the plants will deprive the caterpillars 

 from shelter during pupation and expose them to attack by na- 

 tural enemies and other untoward conditions. Frequent cultiva- 

 tion of the soil between the plants will strengthen them at the 

 same time destroying what larvae may be harbored beneath the 

 surface. Finally, good attention to the plants in the way of an 

 ample supply of food and water will envigorate the plants to 

 overcome what injury might have been done to it.
