pletes this remarkable spinning apparatus. The alimentary 

 canal of the imago has been described and 

 figured by Dufour 1 ; it is very different 

 from that of the larva. 



The ant-lion is capable of sustaining 

 prolonged fasts. Dufour kept specimens for 

 six months without any food. These In- 

 sects are said to give off a peculiar ant-like 

 odour, due, it is thought, to their ant- 

 eating habits. Although no species ' in- 

 habits Great Britain, yet one is found in 

 Southern Sweden. Introduced specimens 

 get on very well in confinement in our 

 country, 2 and would probably flourish at 

 large for some years if they were liber- 

 ated. 



Although the number of known species 

 and genera of Myrmeleonides is consider- 

 able that of the species being now 

 upwards of 300 the members of the 

 small genus Myrmeleon are the only forms 

 that are known to make pits of the kind 

 we have described. Other larvae 3 are 

 known similar in general form to the

The most remarkable forms of Myrmeleonides are contained 

 in the genus Palpares. We figure Tomateres citrinus (Fig. 299), 

 an allied genus found in Eastern Africa as far south as Natal. 

 These Insects have conspicuous blotches and marks on their 

 wings. The species of Myrmeleon are similar in form, but are 

 smaller, more feeble, and less ornate in appearance.
