and behind; an inner process which is a narrow thin plate for most of its 
length, terminating apically in a slender spine which curves cephalad 
in a sort of hook; outer division consisting of a long slender style or 
spine which is bent apically and ends acutely, this lying against a twisted 
plate-like division which at its end is sharply bent about the styliform 
division some distance below the end of the latter. (See Pl. XI, fig. 9).

Paraiulus garius sp. nov. 
Head with brown band bordering labial and clypeal margins, the 
lower mesal portion of the clypeus being pale, its upper portion of same 
color as the border but not solid, the dark color a mottling or network 
over a paler background; a black transverse band between the two black 
eyes, this band concavely excised on front each side of middle and enclos- 
ing a pair of small light spots near median line; vertex of head covered 
with close network of black or deep brown color over a lighter back- 
ground, a similar or somewhat paler network covering the stipes of 
mandibles laterally. Antenne dark purplish brown or blackish. Body 
dark or dusky brown the lower portions of sides and the venter paler; 
a continuous dark median longitudinal line along dorsum and a row of 
black dots along each side beginning at about sixth segment; a darker 
ring of more solid color about anterior portion of each segment; a sub- 
circular patch of closely placed light dots on lower portion of each seg- 
ment, and between this patch and the black dot an elongate patch 
similarly formed, while dorsad of the black spot is a third area and be- 
tween the latter and the mid-dorsal line and elongate narrow band or 
line of such light dots; caudad of the latter line and parallel with it is a 
light line or narrow band partly encircling the segment but fading out 
ventrad on each side, this light line being continuous, not broken into 
dots. First segment dark along both anterior and posterior borders. 
Anal scutum dark brown, the yantro-caudal margins pale. Anal vales 
with cephalic portions dark brown, the meso-caudal portions light. 
Legs proximally clear yellow or light brown, the distal articles covered 
with network of dark purplish brown. 
A deep transverse furrow between mesal angles of eyes, to which the 
median longitudinal sulcus across vertex extends. A row of setz along 
labral margin as usual and also a second row of about nine short sete 
across lower portion of clypeus, the latter row being inversely V-shaped 
with the angle very obtuse. 
Antenne of moderate length, slender, not strongly clavate. 
Lateral borders of first dorsal plate not produced; ventro-caudal 
angle in outline sub-rectangular, the vertex rounded, the margin from 
here running obliquely cephalo-dorsad; anterior margin widely rounded,
