44 THE CANADIAN ENTOMOLOGIST 



Whether or not this is normal cannot be told until niore specimens are gathered. 

 Only one nectary is visible but it is distinctly shown. The base is a little wider 

 than in the apterous forms, and is distinctly cone-shaped but with widely sloping 

 sides. Hairs on antennae medium short and not overly abundant; they are 

 shorter on the legs but more abundant. They are fine and inclined backward. 



Measurements. — Abdomen of this individual crushed, approximate length 

 2.5 mm.? Length of antennal segments: III, 0.47 mm.; IV, 0.21 mm.; V, 

 0.27 mm.; VI, 0.22 mm. Total length 1.32 mm. Length of beak: III, 0.21 

 mm.; IV, 0.167 mm.; V, 0.083 mm. Total length 1.6 mm. 



Lachniella pinivora, new species. 



From material collected by A'. D. Hopkins No. 7422. 



Two slides containing six alate specimens. This species resembles L. 

 gracilis quite closely but there is considerable difference between the two, in 

 that the hairs at the base of the tibiae of L. pinivora are longer and more inclined 

 than is the case with L. gracilis. 



Alate viviparous female.- — ^Antennae light coloured at the base of the third, 

 fourth and fifth antennal segments, distal portion of these segments and the 

 sixth dusky. First and second pairs of legs yellowish at the base of the femora 

 and along the middle of the tibiae. Other parts and tarsi deep dusky brown. 

 Hind femora yellow at the base and dark brown at the joint, hind tibiae with 

 yellow area clear and covering about one-third of the segment. Nectaries large 

 and volcano-shaped. Cauda and anal plate both broadly rounded. Third 

 antennal segment with seven medium-sized sensoria widely set apart, fourth 

 with one or two and fifth with two. Third segment shorter than the last three 

 together, five distinctly longer than four and six four-fifths as long as four. 

 Beak short, extending to the farther edge of the middle coxae. Hairs long and 

 drooping, but not so much so as in L. strobi. 



Measurements. — Length of body 2.9 mm. Length of antennal segments: 

 III, 0.55 mm.; IV, 0.22 mm.; V, 0.24 mm.; VI, 0.164 mm. Beak: III, 0.172 

 mm.; IV, 0.15 mm.; VI, 0.63 mm. Total length 1.25 mm. Length of hind 

 tibia 2.29 mm. Hind tarsus 0.27 mm. 



Lachniella edulis, new species. 



From nTaterial collected by Mr. L. C. Bragg at Trinidad, Colorado, June 

 18, 1911, on Pinus edulis. Other specimens collected on the same plant by 

 Professor C. P. Gillette at Walsenburg, Colorado, and by Mr. Bethel, Cannon 

 City, Colorado, may possibly be the same species although some differences 

 have been noticed. Types in writer's collection. 



Apterous viviparous female. — Antennae clear at the base and dusky at the 

 tip. . Two anterior pairs of legs dusky except over a greater portion of the 

 tibia\ Hind legs dusky except a light coloured area near the base of the tibiae. 

 Third antennal segment slightly shorter than the fourth and fifth together; 

 sixth segment about two thirds the length of the fourth. Apterous forms on 

 Prof. Gillette's slide do not show sensoria on the third segment, while those 

 collected by Mr. Breigg have three small ones near the distal end. Fourth 

 segment with one or two and fifth with two sensoria. Nectaries large and 

 volcano-shaped. Antennae and bgdy with a moderate number of medium 

 short hairs, legs more abundantly set with short drooping hairs. Hind tibia' 

 distinctly curved.
