•stable fly to bite until twenty-four hours after emerging from 

 the pupa. [Mitzmain got them to bite at the end of eight 

 hours.] Usually it feeds not oftener than once in twenty-four 

 hours. 



Hueguenin (41) informs us that a Noctuid moth (Heliothis 

 dispaceus), which feeds on the tar weed, also feeds on the larva 

 of Pontia rapae. 



Isely (43) reports that the young of all the Eumenidae studied 

 by him feed on the plant-feeding larvae of other insects. 



King (47) finds that the mite Gemasus immanis Berl. feeds on 

 Oligochaetes. Truessart claims that Molgus littoralis feeds on 

 ■Collembola; but King could not induce this mite to do so. He 

 found it feeding on living Diptera. 



Merrill (60) found a Clerid larva eating the caterpillars of 

 the codling moth. Palmer (67) finds that the amount eaten 

 by the larvae of the lady beetles varies with the weather and 

 the size of the larva; and that the quantity eaten by the adult 

 varies with the weather and the egg-laying activity. None feeds 

 on vegetable matter; all eat plant lice. 



The Severins and Hartung (79) find that the melon fly (Dacus 

 curcibitae) feeds upon the cucumber, egg-plant, kohlrabi, musk- 

 melon, pumpkin, squash, string bean, tomato, watermelon, wild 

 cucurbit, mango, orange (?), and papaya. They feed from sun- 

 rise until 10 A. M., and rest during the hottest part of the day. 



Venerables (91) finds the adult saw-fly Tenthredo variegatus 

 feeds upon small Dipterous insects. 



According to Welch (100) the young of Hydromyza confluens 

 .Loew. feeds on the waterlily. 



Williams' investigations (103) show that the larva of the 

 tiger beetle, Amblychila cylindriformis Say, comes to the sur- 

 face at night and feeds on a variety of insects. It rejects dis- 

 tasteful ones, sometimes relinquishes an . edible insect that it 

 cannot subdue, and is occasionally overcome by its intended 

 prey. 



In another paper on solitary wasps, Williams (102) states that 

 Harpactus gyponae stocks its nest with Gyoina cineres, a Jassid; 

 that Mimesa argentifrons stocks its nest with Athysanus exitiosa, 

 another Jassid; and that Priononyx rufiventris feeds its young 

 on several species of short-horned grasshoppers. 



In the following table Williams (101) has condensed much of
