 He states that this beneficial species was so abundant as to infest nearly 

 every cocoon transmitted to Iiim In' one corresponthMit. lie also records 

 several plant bug's, one similar to 1' o d i s u s s p i n o s u s I )al]as, as |)reyinir 

 on the sawlly lar\ae. Dr Lintner observed this plant bu^r feedinj^ on the 

 sawlly larvae. lie states that the full jj^rown caterpillars were fearlessly 

 seized and firmly heUl till their (luids were extracted. 



Remedial measures. There is very little that can be done in checkini^r 

 this insect in nati\e swanii)s. \'alued trees on lawns can be protected from 

 injury i)y thorout^h sprayini,^ with an arsenical poison. It is very probable 

 that one of the prepared forms of arsenate of lead would prove most 

 effective.

Pine needle gall fly 



Cecido»iyia pini-rioidac Pack. 



The basal enlargement of shortened, deformed pitch pine needles contain at certain 

 seasons thick orange colored larvae. 



The work of this interesting gall tly was met with at Karner during 



.several years, though at no time was it excessively abundant. The attack 



was in most cases confined to one or two tips on the tree and a considerable 



proportion of the needles would be affected, indicating that the female 



probably remains on one branch and deposits a large proportion of the 



eggs at the base of adjacent developing needles [pi. 20, fig. 4]. This insect 



was observed by its describer, Dr Packard, at Brunswick Me., in 1862 or 



1863. He found the larvact in September of that year and states that when 



fully developed it forsakes the gall, ascends to the terminal buds and
