known inhabitant of aspens. These latter, however, wereahnost all in 

 the larval condition, while Brachyarfhriim was mature : it is, therefore, 

 a somewhat earlier insect than the Orthotylus. It is very active and 

 readily takes fiio^ht ; when in the net, it mii^ht, but for this, and its 

 somewhat larger size, be mistaken for Plagiognathus arhustorum. It 

 has hitherto been recorded only from Scandinavia, Finland, and 

 Bohemia.

A NEW OPOGONA ATTACHED TO SUGAR-CANE. 

 BY E. MEYRICK, B.A., F.R.S. 



The following' moth has been sent me for identification by 

 Mr. Ct. a. K. Marshall, Director of the Imperial Bureau of Entomology, 

 and appears to be of economic interest. 



Opogona glycyphaga n. sp. 



?. 1.5-16 mm. Head and thorax deep purple-bronze, face wliitisli. Palpi 

 ochreons-whitish, terminal joint suffused with dark fviscous. Antennae ochreous- 

 whitish, basal joint and extreme base of stalk dark purple-bronze. Abdomen 

 whitish-ochreous. Fore-wino^s lanceolate, apex acutely produced ; light ochreous- 

 yellow ; a deep purple streak along basal fifth of costa ; a narrow purple-fuscous 

 terminal fascia, widest on costa where it occupies nearly 4, anterior edge form- 

 ing two rounded convexities with a triangular indentation between them, both 

 convexities suffused anteriorly with deep blue and margined on their upper 

 portions with blackish : cilia light grey, basal foui'th on termen bronzy-fuscous. 

 Hind-wings bronzy-grey ; cilia light ochreous-yellowish. 



Queensland, Gordonvale, near Bi-isbane, bred in June by 

 Mr. E. Jarvis, Queensland Government Entomologist, who calls it the 

 " bvid-moth of the sugar-cane,'' and will doubtless publish its life- 

 history ; two specimens. Type in British Museum The species of 

 Ojjogona are fairly numerous in the tropics, and I am acquainted with 

 about 70 ; the known larvae habitually feed on dry vegetable matter, 

 such as dead leaves or refuse, in dry stems, or the interior of the nests 

 of Termites. They are liable to artificial introduction in the larval 

 state, and two or three have thus Ijeen extended in range, but are not 

 usually injurious.
