brighter, more uniform testaceous colour ; the clypeus is deeply in- 

 cised in the middle at the apex ; the sides of the incision forming stout 

 teeth ; there is a yellow spot on the sides of the post-scutellum. 



Comes near to O. sikhimensis , Bingh. 0, prudejis, Nurse, 

 may be known from it by the sides of the post-scutellum not 

 being raised into blunt teeth.

SOME TASMANIAN CASE -BEARING LEPIDOPTEEA. 

 By Frank M. Littler, F.E.S., M.A.O.U. 



The study of the life-history of case-bearing lepidopterous 

 larvae is always a subject of interest to entomologists, as there is 

 so much mystery attaching to them. One never knows what un- 

 expected trait is next going to be brought to light. For some 

 time past I have been closely investigating the habits of two 

 species — one a Psychidae, and the other one of the Tineidfe. 

 Other species have been less studied, owing to paucity of mate- 

 rial ; these will be touched on in due course. 



It is my intention to give an account of my investigations as 

 far as they go, in the hope they will be of some little interest to 

 my fellow-entomologists. To say that I was surprised at some 

 of the unexpected phases observed is no exaggeration. 



Clania lewinii, Westw. 



^ . 25-28 mm. Head, thorax, and antennfe blackish ; face white ; 

 thorax with two white moderate longitudinal stripes ; patagia white, 

 abdomen black ; legs black. Fore wings elongate, moderate ; costa 

 nearly straight ; termen oblique, semi-hyaline, finely irrorated with 

 black scales, especially on margins ; cell almost clear transparent. 

 Hind whigs with termen rounded, very faintly sinuate beyond middle ; 

 colour as in fore wings ; a few blackish hairs towards base. 



? . 12-14 mm. Rich cream colour, with the exception of the 

 head and thoracic segments, which are brown. Quite naked, except 

 for a slight pilose fringe of yellowish-white hair on the anal segments, 

 which has the appearance of a tonsure in miniature. The legs, save 

 for the first pair, are rudimentary, and they are but apologies, quite 

 powerless for locomotion. The mouth-parts are very indistinct, and 

 appear coalesced. Eyes absent, merely dark marks where they 

 should be. 



That it should be sightless, and without power of locomotion, 

 is not surprising, seeing that it never leaves the case, even for a 

 short time. When the maggot-like imago is taken from its case, 

 and turned on its back on, say, a table, it has a curious method 

 of righting itself. Commencing at the anal extremity, the con- 

 tents of the body are seemingly forced up towards the head in a
