known species. The nectaries are small and without the large cone- 

 shaped base found in most species of Lachnids. Length of body, 1.5 mm. 



Alatc viviparous female. The antennae are five-segmented, as shown 

 in Plate I, B, fig. 6. General color, yellowish green, the thorax being 

 brownish (?). The abdomen is marked with a series of brown spots 

 which occur in longitudinal rows. The antennae are short and have 

 five segments; distal half of the third and the fourth and fifth seg- 

 ments brown. The fifth segment is longer than the fourth, and the 

 fourth and fifth together are slightly longer than the third; third seg- 

 ment with three and sometimes four roundish sensoria ; fourth with 

 one large one at the distal end, and the fifth with one large and several 

 small ones near the tip. The head is set with coarse spines, six of 

 which are set in front. Similar spines are found on the body. The 

 antennae have a few inconspicuous spines widely set apart. The legs 

 are distinctly spiny, but not as much so as in Essigella calif oniica. The 

 rostrum is short with the third and fourth segments quadrangular and 

 the terminal segment half moon-shaped and not acutely pointed as in 

 other species of Lacluiiuac. Wings long and narrow, front wing 

 usually with the median vein simple. The tibiae are short and rather 

 stout, while in E. calif oniica they are longer and more slender. The 

 nectaries are but openings with thickened edges. The cauda is angu- 

 lar with the tip elongated into a sharp nipple-like projection.
