neath, posterior pair pale, turned downward more than the anterior, 
which are brownish dusky. Plate of seventh segment beneath indis- 
tinetly marked. ‘Tip of abdomen hairy. 
Length 1.18 mm., breadth .6 mm., antenna .388 mm. 
Described from five specimens found on grass roots. 
Winged Viviparous Female (Plate VIII, Fig. 6).—EKlongate, 
smooth, with sparse inconspicuous hairs, dirty whitish, varied with fus- 
cous and dark brownish, dotted with white at origin of hairs. Mead 
above and mesothorax above and below dark brownish, edges of meso- 
and meta-thoracic plates with blackish outlines. Remaining surface 
markings fuscous brown, sutures whitish. 
Antenne fuscous brown, apex darker, base of third joint paler, ba- 
sal two joints one half thicker than the others; IV a little more than 
twice as long as thick, V.a little longer, VI nearly half longer than 
IV, the spur three eighths of its length; ILI about equal to V and VI 
combined; I and IL combined about equal to VI. Sensoria distinet, one 
at tip (beneath) of joints ITI, IV, and V, and at base of spur on VI, 
last two quite large, that on VI accompanied by the usual group of 
smaller sensoria. Often one at middle also of ILL, and sometimes a third 
near by it. Hyes brownish black, ocelli distinet. A pale notch on hinder 
margin of head just within each eye. 
Prothorax with a dusky band anteriorly, behind this a pair of large 
transverse spots, sometimes a small pair behind these. Mesothorax with 
pale spots at sides. Metathorax with a narrow transverse mark of dusky 
brown. Wings with a granulated surface, veins and stigma light brown- 
ish, stigma half as wide as long on costal margin; cubital obsolete two 
thirds of distance from base to the fork; stigmal vein but feebly curved. 
Running parallel to the posterior margin of the posteostal vein and 
stigma, and separated from them by a narrow paler interval, is a dis- 
tinct and narrow thickening and darkening of the wing. 
Abdominal segments with a row of marginal blotches, one on each 
segment. ‘The double row of small spots in the sutures is present, but 
confused with the discal markings. First and second abdominal seg- 
ments each with a short transverse discal band; bands of next three seg: 
ments more or less confluent, forming a fuscous brown patch; sixth 
segment with a long discal band; those on seventh and eighth extending 
to margin. Cornicles distinctly indicated by a fine dark ring in the 
marginal patch of the sixth segment. Cauda short, not projecting, it 
and anal plate fuscous brown, hairy. 
Beak as in viviparous female, attaining hind coxe. Prothorax most- 
ly pale beneath; mesothorax pale only around the cox; metathorax 
with blackish transverse line, ends of latter partly surrounding coxze. 
Legs darker fuscous brown, first tarsal joint prominent. In the suture 
back of the prothorax is an elongate spiracle in a small transverse dusky 
brownish spot; just below the margin of the prothorax is a large oval 
excretory pore. The abdomen beneath is pale, first and second seg- 
ments, and sometimes the sixth, each with a short discal transverse 
line. Seventh with usual oblong dark plate, which is hairy like the anal
