color. Head of a more decided yellow than body, with usually a dark brown spot 

 above, one nearly of the same size at the upper front, and two rather smaller ones at 

 each side— joined by a brown line — the anterior spot being lower down than the other. 

 In certain specimens these two are blended, and there is but a triangular spot on the 

 top of the head, while the depth of shading on the body is also variable. 



Pupa — Of a dingy, greenish-white color, the members being somewhat paler than 

 the body. 



Numerous specimens in all states examined.

[Ord. Hymenoptera ; Fam. Tenthre-dinid.e ] 



Belonging to the same Saw-fly family as the preceding species, 

 are certain false-caterpillars which are very injurious to pines. They 

 belong to the genus Lophyrus, so named from the plume-like anten- 

 nae of the males. In Germany whole forests of pine and fir trees have 

 [F's- 1^- been destroyed by insects of 



this genus, and D. E. Miller has 

 published a large volume on 

 the depredations of four spe- 

 cies which destroyed thou- 

 sands of acres of pines in Fran- 

 conia. Two species more par- 

 ticularly occur in the Missis- 

 sippi Valley, and the one un- 

 der consideration is the most 

 injurious of the two. The hab-

Abbot's White Tine Worm has been more frequently sent to me, 

 with complaints of injury, from Indiana and Illinois. Yet it occurs 

 over a wide extent of country, and in the columns of the Rural New 

 Yorker and American Agriculturist frequent records of its injuries in 

 the East are to be found of late years. While its injuries are reported 

 from the northern part of Missouri, it seems not to occur in the south- 

 ern part of the State.
