covered with very fine waxy threads, and was found in rows 

 along the needles of Pinus virginiana and Pinus rigida. This 

 species was taken while collecting with Prof. C. P. Gillette, who 

 has already indicated the species in the Journal of Economic 

 Entomology, II, p. 385, 1909. This is the smallest species of this 

 group known to me. 



General color beneath the waxy threads, browTiish tinged with green. These 

 waxy threads are also spread about over the needles causing them to appear 

 as if covered with a bluish powder. No other color notes were taken. 



Apterous viviparous female: Body more robust than that of the alate form, 

 antennae reaching to the third pair of coxae and the beak reaching to the 

 second pair. Beak broad and blunt at the tip. Legs and antennae with 

 numerous long and slender hairs. Third and fourth antennal segments ap- 

 parently without sensoria, fifth and sixth segments with one each. Nectaries 

 small and cone-shaped with a sUght inchnation to bell-shaped. The opening 

 rather large for the base. Cauda bluntly angled. 



Measurements: Length of body, 1.7 mm.; width, 0.84 mm. Length of 

 antennal segments: III, 0.32 mm.; IV, 0.135 mm.; V, 0.14 mm.; VI and spur, 

 0.12 mm. Length of hind tibia, 0.94 mm.; length of hind tarsus, 0.33 mm.; 

 length of hind metatarsus, 0.066 mm. Length of beak, 0.44 mm. 



Alate males and ovoviparous females taken the last of October. 



Alate viviparous female: Body elongate and slender, antennae and legs 

 medium slender and thickly covered with long slender hairs. Antennae rea(5h- 

 ing to the third pair of coxae and the beak reaching to the second pair; beak 

 broad and blunt at the tip. The third antennal segment bears about eight 

 small sensoria; the fourth two and the fifth a single large one near the distal 

 end; sixth with the usual large one near the base of the antennal spur. Wings 

 hyaline and the median vein but a very indistinct single piece as indicated in 

 the accompanying figure. Nectaries small and more or less bell-shaped. The 

 opening rather large for the base. Cauda bluntly angled. 



Measurements: Length of body, 1.48 mm.; width, 0.6 mm. Length of 

 antennal segments: III, 0.32 mm.; IV, 0.154 mm.; V, 0.176 mm.; VI and spur 

 0.154 mm. Length of wing, 2.5 mm.; length of hind tibia, 0.92 mm.; length of 

 hind tarsus, 0.3 mm.; length of hind metatarsus, 0.066 mm.; length of beak, 

 0.49 mm. 



The writer is making an attempt to prepare a contri})ution 

 toward a monograph of the Lachninae, and would appreciate 

 receiving material from all sections of the world. Specimens 

 may be mounted on slides but specimens in 70% alcohol are 

 preferred. In either case, include such color notes as are obtain- 

 able. If specimens are sent in alcohol, put a small amount of 

 cotton in the vial and push down until the material is held firmly
