counties of the State, not a few classing the pest as serious or even 

 severe. 



This insect is closely related to the much better known onion 

 maggot and cabbage maggot, two species which have unenviable 

 reputations in economic literature, owing to the losses they cause. 

 The flies of all three species are dull colored, about one fifth of an 

 inch long and appear much like a small housefly. The parent of the 

 seed corn maggot is doubtless more generally present than has 

 hitherto been supposed. It is probable that it breeds readily in 

 decaying vegetable matter and that the reason the beans were 

 damaged so seriously was due in large measure to the inability of 

 the plants to outgrow attacks by the young maggots which began 

 work on the sprouting beans and would have been practically harm- 

 less under normal conditions. The most obvious preventive measures 

 are to put beans and other crops, such as corn, likely to be injured 

 by this insect upon moderately well-drained land and in wetter 

 seasons, at least, to avoid deep planting, since it is very desirable 

 when such conditions obtain for the plants to make a quick start 

 and grow rapidly. Field conditions prevent the employment of 

 any repellents, such as carbolic acid emulsion or sand and kerosene, 

 though these may be useful in small gardens. 



Juniper plant bug (Chlorochroa uhleri Stal.). This is a 

 large olive green stink bug easily recognized by the marginal pinkish 

 markings. It has been recorded earlier (New York State Museum 

 Bulletin 180, pages 70-71) as injuring sunflower seeds, green corn, 

 peas while still in the pod, tomatoes, currants and blackberries. 



The insect was moderately abundant in early July in a rye field at 

 Schodack, the bugs almost invariably being upon the nearly fully 

 developed heads and apparently feeding. Practically the same 

 conditions were observed except that the related and frequently 

 associated Euschistus variolarius Pal. Beauv. was the 

 more numerous in a rye field one -half of a mile west of Haystack 

 station and a little south of Schuylerville. Messrs C. L. Carden 

 and J. A. Holmes both stated that these bugs were sometimes very 

 abundant in rye fields. This would seem to indicate that these 

 large Pentatomids commonly feed upon several grains and in some 

 instances may cause an appreciable amount of damage, though 

 serious injury is probably very unusual.

 This insect was exceedingly abundant on Osage orange in New
