852 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



34. Lophyrus sp. 



On spruce September 11, 1887 ; a Lophyrus larva, with the head red- 

 dish ; the body pale yellow, with the dark stripes unusually distinct, 

 especially a broad lateral dark brown stripe. An allied species is rep- 

 resented on PI. VIII, figs. 5, 5a. 



35. Lyda sp. 



(Plate X; fig. 7, 7a.) 



Order Hymenoptera ; family Tenthredinid^. 



A Lyda larva, new to me, occurred on the spruce July 1 to 7, 1886, at 

 Brunswick, Me., making a mass of castings 1^ inches in diameter, near 

 the end of the branch, and forming galleries among the castings. The 

 worms, on being placed in another branch, soon spun a large web, 



within which they glided about. They 

 were kept for a number of weeks in 

 confinement under the best possible 

 conditions, but finally died. 



Larva. — Body rather long and slender, but 

 moderately thick ; head and prothorax of the 

 same thickness. Head black, prothoracic seg- 

 ment jet black, with adorsalshield and a lateral 

 rounded boss. Thoracic feet black, Subanal 

 abdominal legs 3-jointed, black, basal joint 

 paler at base. Body dull livid olive green, 

 stained with faint purplish. A dorsal and a 

 vertical median dark diffuse line. Body much 

 wrinkled, with purplish warts on the wrinkles. 

 A distinct lateral raised line. Supraanal plate 

 large, with a V'Shaped raised area and lateral 

 ridges, the sunken spaces between the raised 

 ridges dark. Length, 23""'. 



36. Lyda sp. 



This species appears to be different 

 from the preceding species ; it occurred 

 on the spruce at Brunswick, Me., Sep- 

 tember 18, 1884. 



Larva. — Body of the usual shape. Head dark, 

 pitchy-brown ; the prothoracic shield small and 

 of the same color as the head. Body pale, flesh- 

 reddish-brown.
