but dusky at the tip and shading into colour of other segments, the last one 

 being nearly black. First and second pair of legs dark to black, except the 

 greater portion of the tibiae. Hind legs almost black throughout except a small, 

 dusky area near the base. Antennal segments as in the apterous forms, except 

 that the fifth segment is longer than the fourth. Third segment with six, the 

 fourth with two or three, and the fifth with two large sensoria. The sensoria 

 are unusually large as in the apterous forms, and are volcanic in shape rather 

 than cone-shaped. The legs and antennae are quite hairy, and those of the 

 base of the tibia^ are upstanding while those farther outward are inclined. Cauda 

 angular but broadh' rounded at the tip. 



Measurements. — Length of body 3.88 mm. Length of antennal segments: 

 III, 0.52 mm.; IV, 0.187 mm.; V, 0.23 mm.; VI, 0.166 mm. Total length 1.2 

 mm. Beak: III, 0.21 mm.; IV, 0.175 mm.; V, 0.063 mm. Total length 1.9 

 mm. Length of hind tibiae 2.42 mm.; hind tarsus 0.31 mm. 



Lachniella pacifica, n. sp. 



From materal bearing accession numbers of A. D. Hopkins and Theo. 

 Pergande, collected at Eureka, California, May 19, 1903, on Abies graniis. 

 Three alate specimens, several pupae and one apterous specimen in poor condition. 

 However, general characters of species quite distinct. Types in U. S. Bureau 

 of Entomology collection. 



Alate viviparous female. — In balsam the legs appear to have been fairly 

 dusky throughout, although the hind pair are much darker than the others. 

 Hind tibiae with onl)' a faint indication of the usually light area near the base 

 of the tibiae. Antennae rather stout, third segment with seven to nine large 

 sensoria, fourth with three and fifth with two. Nectaries mostly obscured but 

 appear to be small and having a comparatively small base. Antennae, legs and 

 body with short hairs of rather fine texture. On the femora and base of the 

 tibiae they stand erect, while toward the tip of the latter they are inclined. 



Measurements. — Length of body 1.86 mm.? Length of antennal segments: 

 III, 0.41 mm.; IV, 0.166 mm.; V, 0.187 mm.; VI, 0.12 mm.? Total length 

 1.04 mm.? Beak: III, 0.187 mm.; IV, 0.145 mm.; V, 0.063 mm. Total length 

 1.78 mm. Length of hind tibiae 1.86 mm.; tarsus 0.31 mm. 



Lachniella atlantica, n. sp 



From material collected by L. C. Bragg, at Webster, Massachusetts, 

 June 19, 1909, on Pinus sp. Two slides containing three alate and five apterous 

 forms. One slide in writer's collection, others in collection of C. P. Gillette. 



Apterous viviparous female. — Antennae light at base of third segment, 

 remaining parts dusky black. All three pairs of legs black except the base of 

 the femora, and a yellow area toward the base of each tibia. Third antennal 

 segment approximately equal in length to the fourth and fifth together. Fourth 

 segment slightly shorter than the fifth, and the sixth shorter than the fourth. 

 Third segment with a single sensoria, fourth with one and fifth with two. Beak 

 extending to the tip of the abdomen. Nectaries extremely large, volcano- 

 shaped.
