■distal half. Of twenty segments examined, two had one sensorium, eight had 

 two sensoria, seven had three, and three had four sensoria. On segment III 

 there are from ten to seventeen secondary sensoria scattered irregularly along 

 the entire length of the segment. Of twenty segments examined, two had ten 

 sensoria, three had eleven, five had twelve, three had thirteen, tlu'ee had four- 

 teen, one had fifteen, two had sixteen, and one had seventeen. The thorax 

 is brown, with the lobes ahnost ])lack. A pair of small but distinct lateral 

 tubercles is present on the prothorax. The abdomen is green, with dark mark- 

 ings in the form of cross bands and spots on the dorsum. Lateral tubercles 

 are present on the fii'st and seventh segments. The •cornicles (fig. 22) are 

 brown, distinctly imbricated, almost cylindi'ical, and about equal in length 

 to segments IV or V of the antennae, being considerably shorter than III. 

 The Cauda (fig. 23) is ensiform, light brown, with the distal end slightly darker, 

 a little more than half the length of the cornicles and about the same length 

 as the liind tarsi, or perhaps slightly longer. The legs are pale, with the coxae, 

 tarsi, apical two-thii'ds of the femora, and apices of the tibiae dusk}-. The 

 wings are normal, hyaline, stigma light brown or amber, veins brown. 



Measurements: Bodj^ length, .98 mm.: width of thorax, .48 mm.: antennae 

 total, .81 mm. ; III, .20-.23 mm. ; IV, .14 mm. ; V, .12-14 mm. ; VI base, .08 mm. ; 

 VI spur, .15 mm.: cornicles, .14 mm.: cauda, .08 mm.: hind tarsus, .08 mm.: 

 wing length, 2.07-2.11 mm.; wing width, .780-.810 mm. 



Apterous viviparous female. Prevailing color a rich dark green with head 

 dusky brown. Eyes are red. Antennae are dusky brown tlu'oughout, reach- 

 ing to the base of the (!ornicles, with only the usual primary and accessory 

 sensoria present. Segment III is the longest segment, with IV, \, and the spur 

 of VI following, all of which are subequal, or in some cases with IV slightly the 

 longest, V being next. I and II are subequal and slightly shorter than the 

 base of VI. Very small Init fairly distinct antcnnal tubercles are present . The 

 beak is light green, with the tip dusky, and reaching to the middle of the third 

 coxae. The thorax and abdomen are rich green without dorsal markings. 

 Lateral tubercles are present on the prothorax and on the" first, second, and 

 seventh abdominal segments. The cornicles are concolorous with the abdo- 

 men, or very slightly darker, -with the tip dusky, tapering slightly from base 

 to apex a'nd about as long as segment III of the antennae. The cauda is about 

 one-half the length of the cornicles, lacing about one-half as long again as the 

 hind tarsi, ensiform, concolorous with the abdomen, or with the distal end 

 slightl}^ dusky. The anal plate is dusky and half-moon shai)ed. The legs 

 are pale with the coxae, tarsi, and tips of the til)iae dusky. 



Measurements: Body length, 1.14 mm.: width of thorax, .67 mm.: antennae 

 total, .95 mm.; Ill, .25-.26 mm.; IV, .17-.19 mm.; V, .16 mm.; VI base, .09 

 mm.; VI spm', .14 mm.: cornicles, .25 nun.: cauda, .12 nun.
