CHAP. X. HOW TO IDENTIFY THE ORDERS OF LARVJB. 59 



Asparagus-beetle (Fig. 171) and the larva of the Rove-beetle 

 (Fig. 172) belong either to the Order Coleoptera or Neu- 

 roptera. If terrestrial, they probably belong to the Order 

 Coleoptera the only Neuropterous Iarva3 which are terrestrial 

 being those of the Lace-winged Flies (Fig. 47) and of the 

 Ant-lions. These larvae differ from the Coleopterous larvae by 

 their long and prominent jaws, which project horizontally in 

 front of the head.

Those larvae which are provided with from ten to sixteen 

 legs; such as are commonly "called "Caterpillars" (as the 

 Parsley - worm. Fig. 173), "Span-worms" or ''Measuring- 

 worms." etc., belong to the Order Lepidoptera. 



Those larva? which are provided with more than sixteen 

 legs are called "False Caterpillars," such as the Pear-slug 

 (Fig. 174); they belong to the Order Hymenoptera, and to 

 the family of Saw-flies.
