CHAP. XII. CLASSIFICATION OF INSECTS INTO FAMILIES. 67 



species attack ripe fruit. The larvae are destitute of feet, and 

 feed upon the food stored up by the parents. 



SAND- WASPS OR WOOD- WASPS {Crabronidve, Nyssonidas, Bern- 

 heridfe, etc.). These insects usually have large heads, and the 

 antennae are sometimes elbowed. They build their nests in 

 holes in wood, in the stems of plants, or in the earth, and 

 store them with spiders, flies, plant-lice, etc. The Iarva3 are 

 destitute of legs, and feed upon the food stored up by the 

 parent insects. 



DIGGER-WASPS (Pompilidse, etc.). These wasps have long 



and usually spiny legs and 

 large jaws; the antennas are 

 not elbowed, and the abdo- 

 men is petiolate. They build 

 their nests in holes which 

 they dig in the earth, storing 

 them with insects and spiders. 

 A . few kinds are known to 



feed upon over-ripe fruit; such as the Red- winged Wasp 

 (Fig. 184). The larva? are destitute of feet. A large species 

 of this Family is commonly called the "Tarantula Hawk." 

 ANTS ( FormicidtK ) . The males and females, when they first 

 issue from the pupa, are usually provided with four wings, 

 but the workers are wingless; the antennae are always elbowed. 

 The larvae are footless, and are fed upon food which has been 

 elaborated in the stomachs of the workers. 



GOLDEN- WASPS (ChryMidae). These insects are either green 

 or black; the antennae are elbowed and composed of thirteen 

 joints; the eyes are oval and the ocelli are distinct. The larvae 

 are destitute of feet and live in the nests of Bees or Wasps, 

 first destroying the original inhabitant, and then feeding upon 

 the food that has been stored up for it. 



ICHNEUMON-FLIES (Ichneumonidx). These insects have. 

 long antennae, composed of from fifteen to fifty joints, as the 

 Ring-legged Pimpla (Fig. 184) and the delicate Long-sting 

 (Fig. 131), and their antennae are not usually elbowed;
