494 Report of the Department of Entomology of the 



Davis of Staten Island reports that he has also found eggs of this 

 insect in wild cherry, white ash and Baptisia tindoria. In going 

 over the literature of this species we have found numerous descrip- 

 tions of the work of this insect in various plants besides those given 

 above, but always under the name of niveus. When the eggs are 

 described as deposited in long rows there is little doubt as to their 

 identity; for the only other widely distributed species with this 

 habit is CE. quadripunctatus, which deposits eggs only in smaller 

 and more delicate plants. On this assumption additional host 

 plants as recorded in literature are currant, Helianthus, artichoke, 

 Ambrosia, plum, cottonwood, box elder, cherry, dogwood, black 

 locust, honey locust, sycamore and catalpa. 



LOCAL DISTRIBUTION OF THE INSECT. 



The foregoing list of plants furnishes a very good key to the habitat 

 of this species. It will be noticed that most of the plants named 

 are those which grow best in low, moist places and some are character- 

 istic of waste places. While the list contains quite a number of 

 trees, it has been our experience that oviposition in these is only of 

 rare or local occurrence or as a result of small seedling trees growing 

 among other plants. The two types of localities where these tree 

 crickets occur in greatest abundance are low lands with a dense 

 growth of tall herbaceous plants, such as Solidago, Erigeron, Helian- 

 thus, etc., and on land of any kind that has grown up to bushes, 

 briars and wild grape vines. The insects are less common in culti- 

 vated berry patches, nurseries and orchards, but even in these 

 situations and especially in raspberry plantings they are sometimes 

 numerous enough to be destructive. 



FEEDING HABITS. 



We have observed this species in the field feeding on the petals 

 and anthers of flowers and on raspberry leaves and fruit. (Plate 

 XXXVII.) Only in the cages have we detected it feeding on plant lice 

 or other insects. An examination of the crops of a number of speci- 

 mens mostly in the fourth instar collected in a raspberry planting, 

 indicates that they feed more extensively on plant than on animal 

 matter. In a few instances there were distinct insect remains, but 

 these constituted a small part of the entire contents of the crop, which 

 was mostly filled with leaf tissue, some fungus mycelium and spores.
