distinct nor regular : eyes prominent. These insects have hitherto been 

 found only in Australia, but it is possible they may be found on the 

 Eucalyptus imported thence and now common in India. The genera 

 created by Schrader are : — 



1. Brachyscelis, in which ? has six legs complete, but short and 

 unfit for use. 



2. Opisthoscelis, in which ? has only two long posterior legs. 



3. Ascelis, in which 2 is apodous. 



In Opisthoscelis, the galls of both sexes are often found under the 

 same leaf : that of the 9 is in the shape of a pea, but somewhat larger ; 

 that of the $ is very small and conical. The ? of 0. suhrotunda is of 

 a crimson red colour, nearly round, but the terminal segment of the 

 abdomen is very much tapered ; the S is of a red colour, with anal 

 setae ; the body, legs, and antennse are very hirsute : long about 2'". 



In Ascelis, the $ larvae alone form galls ; the c? undergoing its 

 changes within the gall of the parent ? . This 9 is of a pale yellow 

 colour, the segments are hardly visible, and it appears as a mass of 

 apparently inert matter without external members. The dorsum has 

 a three-pointed corneous process, which always holds some gum apparent- 

 ly intended to close the opening of the gall, which is here always on 

 the upper side of the leaf to which the gall is attached. The galls are 

 usually of a large, globose form, and also in the form of large flat 

 swellings on both sides of the leaves. The larva is flat and transparent, 

 and resembles that of Brachyscelis, except that it is more pointed at the 

 apex, has shorter antennae, short anal setee, and has not so much hair 

 fringing the abdomen. The d larva changes in the parent gall to a 

 second form, which is red, active, and somewhat longer than the first 

 change, but narrow and with very short anal setae ; after this it changes 

 to a pupa and then to an imago, which is also of a crimson colour.

'This group comprises those genera in which the insect is either 

 naked or inclosed, clothed with a waxy or cottony substance, or even 

 completely enveloped, and in such case the 9 rests naked on its food- 

 plant and forms a cottony secretion between the abdominal skin and 

 the bark in which the eggs are placed. The form varies much ; some- 

 times flat or globular, oval or circular, soft or semi-corneous. The 

 rostral filaments have their source between the first pair of feet and
