Notes on Insects Damaging Sugar Cane in Queensland. 15 



is scape-like and directed obliquely to each side of the head. (Plate II., 

 Fig. M.) A fuller account of this cane pest, including notes on its 

 control, are given in a paper by the writer entitled " The Sugar-Cane 

 Bud-Moth " (Queensland Agricultural Journal, vol. 3, p. 72, 

 1915). A chalcid parasite, Stomatoceras gracUicorpus, Girault, has been 

 bred by us from pup» of this moth. 



(6) LOXOSTOMA, ? sp. (Family TINEIDAE). 

 Plate I., Fig. 6, p. 6. 

 Closely resembles the foregoing in general habits and economy, but 

 is a smaller and seemingly less plentiful species. 



Colouration of Moth. 

 Fore-wings light-yellow with three brown blotches on costa, edged 

 with golden scales, the blotch at basal portion of wing being about twice 

 the length of the others ; a short bar consisting of golden scales is placed 

 lengthwise in centre of wing, and the fringed portion of hind margin 

 blotched irregularly with golden and dark-brown scales. Hind-wings 

 and all fringes silvery brown. Antenna light yellow, basal joint swollen 

 and brown. Front of head and patagia tufted with large reddish-brown 

 scales. Wing expanse, 9 mm. Length of body, 4 mm. 



(7) COSMOPTERYX, sp. (Family ELACHISTIDAE). 

 Plate I., Fig. 7 c-d, p. 6. 

 This insect occurs more or less freely in canefields but fortunately 

 rarely attacks very young foliage. 



The larva? bore the mid-rib, occasioning internal injuries, which 

 soon become conspicuous owing to the damaged tissue turning red and 

 revealing the presence of exten.sive tunnelling (see Plate I., Fig. D). 

 Injuries are confined chiefly to the basal portions of older leaves but 

 may extend the whole length of the mid-rib, and exceptionally cause 

 premature withering of the leaf -blade. 



Description of Larva. 

 Dull white, deeply segmented, and with a few scattered short white 

 hairs. First thoracic segment wider than the others. Head large, eyes 

 light yellow, mandibles brown. Length, 6 mm. (see Plate I., Fig. C). 



Colouration of Motli. 

 The perfect insect is beautifully adorned with the broad golden 

 fascia and metallic blotches so characteristic of this interesting genus, 

 and with the help of a pocket lens is easily identifiable from the follow- 

 ing description: — Thorax and basal half of fore-wings gray, striped 

 longitudinally with silver. Dorsal surface of head smooth and white. 

 Fore-wings just beyond middle crossed by a broad transverse golden-
