204 A MANUAL OF DANGEROUS INSECTS. 



Description and biology: Adult, brownish with white-lined veins and margins of 

 segments; wings with two darker bands; antennae long. Wing expanse 20-30 mm. 

 Pupa 12-14 mm. long, light brown. Larva 27 mm. long, green with a few scattered 

 hairs; head pale yellowish. The larva feeds on the leaf, folding it into a tube to 

 protect itself while feeding, changing to a new leaf when it has eaten all it can. When 

 disturbed it drops to the ground. Eggs laid in email clusters arranged in rows on the 

 surface of leaves. (See plate xlv.) 



Distribution: Hawaii, Peru.

Polyocha saccharella Dudgeon. 



(Cane Root Borer. Pyralidse; Lepidoptera.) 



Hosts: Sugar cane. 



Injury: Causes stunted growth and shriveling of plants by boring in stalks and roots. 



Description and biology: Moth small, brown, with hind wings white. Pupates in 

 etalk. Larva about 0.75 inch in length, of white color; bores in stalk and root; hiber- 

 nates in root; before pupating it eats an opening in the stem and covers it with silk.

Ereunetis flavistrlata Walsmgham. 



(Sugar-Cane Bud Moth. Tineidse; Lepidoptera.) 



Hosts: Sugar cane, palms, banana, pineapple, Pandanus. 



Injury: While this species mainly lives in the dead tissues of the above food plants, 

 it breeds in cane stalks among the dry leaves, but often eats out the eyes or buds, 

 thus destroying the propagating value of the cane. It may easily be transported in 

 seed cane. 



Description and biology: A small moth, measuring 14 mm. in wing expanse, head 

 and thorax yellowish white, forewings yellowish white, with indistinct yellow streaks, 

 hind wings shining pale golden yellow, becoming white at apex. Pupa 5 to 6 mm. 

 long, pale yellowish brown. Larva 12 to 15 mm. long, whitish, head reddish brown, 

 hairs on darker tubercles. The larva usually feeds in the dried leaf sheaths, but 

 sometimes attacks the rind, giving entrance to fungi, and does the greatest damage 

 by eating out the eyes. 



Distribution: Hawaii.

Laspeyresla schlstaceana Sn. (Grapholitha). 



(Gray Borer of the Sugar Cane. Tortricidse; Lepidoptera.) 



Hosts: Sugar cane. 



Injury: Very important in Java. Is liable to importation in seed cane. 



Description and biology: Moth about 12 mm. long, grayish brown. Pupa reddish 

 brown, 8-13 mm. long. Larva yellowish, with head and collar on prothorax as well 

 as two apical segments chitinized reddish brown. Hairs sparse on brownish spots. 

 The larva bores in stalks of the cane. Eggs oval; about 120 to 170 are laid in a row 

 under the leaf or behind the sheath of the cane. 



Distribution: Java.
