Apterous viviparous female. — Specimens in balsam collected by Theo. 

 Pergande, from Finns inops in Virginia near Washington, D.C., June 9, 1903. 

 The prominent character of this species is the deep brown to almost jet black 

 tibia^ set with heavy leaning spines. 



Antonniv medium slender and extending to the second pair of coxai. All 

 segments light coloured at the base, dusky toward the tip. Sixth segment 

 fingerlike and approximately as long as the fourth. Fifth segment with three 

 small sensoria toward the distal end. Beak short, reaching to the base of the 

 third pair of coxae. Tip dusky black. 



Nectaries conical and with a widel}^ sloping base. Cauda bluntly angled 

 and short. Abdomen covered with irregular black spots, a hair arising from 

 each one. The purpose of these spots has not been determined ; outside these 

 are found other hairs or bristles, the entire body being set with numerous 

 long spinclike hairs. 



The femora are brown in colour and the spines, which are not as coarse as 

 those on the tibi?e, stand more nearly upright. The tibial spines are set in a 

 leaning position pointing toward the tarsi. 



Measurements. — Length of body 4.16 mm. Antenna! segments: III, 0.52 

 mm. ; IV, 0.29 mm. ; V, 0.31 mm. ; VI, 0.25 mm. Total length 1.52 mm. Length 

 of beak 1.5 mm. Hind tibiae 2.39 mm. 



Alate viviparous female. — Specimens in balsam collected by Theo. Pergande, 

 on Pinus inops, Catholic University, D.C., June 19, 1905, and by H. F. Wilson

 insects, a pleasure that arises not only from the intrinsic value of an important 

 series of investigations thoroughly prosecuted, but also from the assurance that
