of August. The adults of ilie second q'encration winter in the cocoons. 

 The ei^JL^s are deposited in little slits in the leaves. I )r Riley states that 

 some of the tlies appear early in th(- sprin^', while others do not issue till 

 the latter [Kirt of June. A sinL,de parasite, Linineria lophyri Riley, 

 has been rearetl from this species. 



Description. The adults have bein descrihcnl by Mr .Saunders practi- 

 cally as follows : 



The male has a wing spread of about ^ inch and the female of 73 

 inch. The body of the male is black, e.xcepting the \ellowish underside, 

 and tip of the abdomen. The female is honey-yellow, with the head and 

 thorax a little darker, the thorax with the abdomen being slighth' marketl 

 with black. The wings are transparent with black veins. 



Thi- full grown sawHy larva has a black head, the body is yellowish 



white and is ornamented with two rows of oblong square black spots down 



the back. On each side thert! is another row of about 11 black, nearly 



square spots, they being a little longer than broad. 



Fir sawfly 



Lophyrtis abictis Harr. 



Clusters of black headed, dark ,t;reeii, dark striped caterpillars about y'z inch long, 

 defoliate fir, spruce and [litcli pine in niidsiinimcr and prol)ably early fall. 



This sawlly is one of the rarer species occurring on hard pine. It 

 was taken by us in small nimibers on hard pine at Karner in early June and 

 again the latter part of July. It is [M-obabk: that this species, like its allies, 

 has two generations, the first produced by adults which hibernate in the 

 cocoons and the second from .sawflies emerging about mitlsummer. This 

 species has been recorded from several northeastern states and Canada, and 

 I)r Fletcher states that Mr Harrington obtained tlu' larvae of this form 

 from spruce and apparently the same thing occurred very abundantly on 

 white cedar. 



Description. The full grown larvae have the head yellowish or lilack 

 and the body a dull green with a pale dorsal stripe ; in some specimens the 

 stripe is lighter on the posterior portions of each segment. There is also a 

 subdorsal and stigmatal paler stripe. The true legs are black and the false
