its wings, which are dusky gray, its abdomen dusky red and 

 slightly covered with fine cottony down. 



"The females of these insects do not extrude their eggs. 

 Clinging closely to the leaf with their heads towards its base, 

 they die, their distended abdomens appearing like a little bag 

 filled with eggs. The outer skin of the abdomen soon perishes 

 and disappears, leaving the mass of eggs adhering to the side 

 of the leaf, but completely covered over and protected by the 

 closed wings of the dead fly, I have met with the dead females 

 thus adhering to the leaves the first of July, and have noticed 

 the same insects on the leaves in full life and vigor the middle 

 of May. 



"The rib vein of the fore wings runs straight to the outer 

 margin forward of the tip, and gives off from its middle on the 

 outer side a very oblique branch which runs to the outer margin, 

 its tip producing a slight angular projection to the edge of the 

 wing, and the whole space on the outer side of the rib vein 

 beyond this branch is more opake than the rest of the wing 

 and of a smoky yellowish color. From its inner side the rib 

 vein sends off three simple oblique veins, the last one of which 

 ends in the extreme tip of the wing. The hind wings have 

 an angular point on their outer side beyond the middle, and 

 a longitudinal rib vein, which, forward of its middle sends off 

 a branch almost transversely inward, its tip curved backward. 

 The antennae are short, thread-like, and composed of four or 

 five small joints. It will hence be seen that this insect is a 

 true Chermes — the first species of this genus that has been dis- 

 covered in this country." 



The fact that a Chermes described by Fitch as 0.08 inches 

 long to the end of the abdomen (0.12 inches long to the tip of 

 the wings) and the accurate and characteristic account of the 

 place and manner of ovipositing on the pine needles could 

 have been considered the same as Chermes pinicorticis* for 

 the past 40 years, is sufficient proof that none of the observers 

 who have worked with pinicorticis have been familiar with 

 Fitch's other species, i. e., pinifoliae.
