Larva. — Full grown. Tortricid in form, the head tapering in front and truncate, 

 pitchy, rugose, with slightly dorsal channel. Mouth parts ample. Upper side of 

 body, except the second segment, which is pitchy, dull pale chocolate brown. Under 

 side sordid white. Spiracles pale pitchy, as are also the thoracic feet. On the dor- 

 sum series of double ovate shining spots, placed transversely, a little darker than the 

 ground color. These spots difi'er in intensity in various individuals. There are a 

 few short hairs upon all the segments, and especially about the head and anal ex- 

 tremity. Length, .35 millimeters. 



Pupa. — Cylindrical, rounded in front, and tapering suddenly posteriorly. Color, 

 bright chestnut-brown in life, changing to pitchy. The head, thorax, and wing 

 cases darker than the rest. Surface very much roughened, the head and thorax 

 being covered with transversely waved ridges. The abdominal segments are also 

 wrinkled, but less rugosely. Wing cases broad, smooth, glossy, those of the antennae 

 being strongly defined. Anal segment rounded. Cremaster short, bifurcate, 

 Length, .23 millimeters. Width across the wing cases, 8 millimeters. 



This pretty species must now be included among the most injurious 

 insects of Australia, and as it is eagerly sought by collectors, its num- 

 bers may be easily kept in check. I have seen it in two collections 

 marked Morgia gigantella Walk. 



STEPS TOWARDS A REVISION OF CHAMBERS'S INDEX, WITH NOTES 

 AND DESCRIPTIONS OF NEW SPECIES.

ARGYRESTHIA Hb. 



Argyresthia plicipunctella Wlsm. 



Hah. : Head of Noyo, Mendocino County, California, 8-11 June, 1871 (5 specimens). 



Crescent City, Del Norte County, California, 22 June, 1872 (I specimen). Kouge 



River, Oregon, 7 May, 1872 (1 specimen). 



The localities where this species was captured were inadvertently omitted from 

 the description' [Insect Life, hi, 120, 1890]. 



COPTOTRICHE Wlsm. 



Coptotriche zelleriella Clem. 



Tischeria zelleriella Clem. 



= complanoides F. and B. {zellerella F. and B. ). 



I have now the female of Tischeria complanoides F. and B., which distinctly con- 

 firms my previous impression that this is truly Tischeria zelleriella Clem. The dark 

 gray hind wings of the female are very noticeable, and the hind wings of the male 

 in bred specimens entirely answer to the description of Clemens, printed in italicsi 

 " tinted with yellow externally towards the tip." 



I had observed that Frey and Boll had overlooked the peculiar form of the hind 

 wings of the male when describing the species under the name complanoides. Thi» 

 is now accounted for by the fact that the female only appears in Frey's collection, 

 whereas the male has turned up from Zeller's collection received from Boll in 1873, 

 labeled "^e^ereZia CI. Fr. E. Z., 73, 220. Boll lit. 4, 73."
