10 THE VICTORIAN NATURALIST. 



3. Pupa. — The male closely resembles M. elongata in shape 

 and colour, and is about three-quarters of an inch long. The 

 female chrysalis is reddish-brown in colour, and is almost 

 cylindrical, with the anal segments bluntly rounded. It is about 

 I inch long and three-eighths of an inch in diameter. 



In common with other Psychidse they lie head downwards in 

 the case. 



4. Imago. — The moths emerge early in the morning during 

 December and January. The male is a brown insect, measuring 

 about 1^8 inches across the wings, wiiich are of a smoky black 

 colour. It possesses the power of extending its abdomen to a 

 considerable extent. The female is a cylindrical cream-coloured 

 insect, so closely resembling M. elongata in its habits as to require 

 no further description. 



III. Clania tenuis, Ros. 



1. Ovum. — The ova resemble those of Entometa ignobilis in 

 all respects excepting that they are rather smaller. They hatch 

 during February and March. 



2. Larva and Pupa. — Great similarity exists between 

 E. ignobilis and C. tennis in both their larval and pupal stages. 

 The construction of the cases is identical in both species, ex- 

 cepting that the young Clania more often uses sticks, etc., before 

 the general reconstruction in October, and the smaller size and 

 somewhat spindle-shaped form of the cases, together with their 

 usually occurring numerously together, serves as a rough guide in 

 separating Clania from the larger species. The larva spins up to 

 pupate in November. 



4. Imago. — The moth emerges usually in January, when the 

 males may be found in the early morning hanging on to the sides 

 of their cases. They are small grey and white insects, measuring 

 I inch across the wings, which are sparsely covered with black 

 scales, giving them a smoky appearance. The female is nearly 

 cylindrical, pale yellow, and devoid of all but the merest rudiments 

 of limbs. The total length of this insect's life appears to be 

 twelve months. 



IV. — Clania lewinii, Westw. 



1. Ovum. — The ova resemble those of C, tenuis. 



2. Larva. — The larvae hatch out in February and March, and, 

 following the instincts of the genus, begin at once to build a case 

 and roam about. Within an hour after they appear outside the 

 parent's case each little grub will have scooped out a hole in a 

 leaf, using the minute fragments removed to build round itself a 

 sort of belt, which it rapidly enlarges till it forms a cone-shaped 

 case. 



The rate at which the case is built is roughly illustrated by the 

 following table : —
