liairs arising* from the pits on the sides. The clypeus with the 
caudal portion fusiform, the cephalic part of this portion nar- j 
lowei than the caudal part; cephalic margin of clypeus with a 
large, prominent, three-toothed lobe on median line: the mesal 
tooth of this lobe is larger and longer than the others; on some 
specimens these teeth are more or less worn off. Labrum ap¬ 
parently wanting, being entirely within the cavity of the mouth, 
the mandibles are large, arcuate, and bear a short curved median 
tooth on the mesal side. The maxillae have the cardo stron°iy 
bilobed; the stipes very slightly diminish in width toward the 
pi oximal end, which is truncate. The sides of the gula are 
nearly parallel, this part being but slightly narrowed towards 
its base; the base is rounded, with one long hair arising from a 
deep excavation near each lateral angle. Prothoracie segment 
subquadrate and nearly as long as the other two thoracic seg¬ 
ments. 1 he remaining segments of the body of nearly uniform ji 
length, slightly constricted at the’sutures, and almost twice as f 
wide as long. The caudal segment is considerably flattened, and 
has a large oval caudal notch formed by two rather long flat¬ 
tened projections, each of which curves slightly dorsad and ter¬ 
minates in two short, blunt, hornv diverging tubercles; the two 
inner tubercles project dorso-mesad, with a small hair-bearing i 
tubercle arising from the lateral aspect; the outer tubercles pro¬ 
ject nearly directly dorsad. The dorsum of the segment is bounded 
by a narrow ridge which on the sides of the segment bears four 
short, distinct, blunt, horny tubercles, the more caudal one bein«* 
consideiably larger. The area bounded by this ridge is convex I 
eephalad, slightly roughened, bears no hairs, and is marked bv 
a deep, roughened, linear depression on each side and a short 
mesal linear impression extending from the middle of the area 
to the caudal notch; ventral portion of the segment slightlv 
wrinkled, the semicircular fold around the anal proleg extends i. 
upon the base of the leg in the form of a thin finely striated 
maigin, the distal margins of the joints of the leg are similarlv 
striated. The prosternum is triangular, and acutely wedge- 
shaped caudad. The thoracic legs are short and stout; each joint 
aimed with short brown spines. Spiracles large, elongate oval, 
brown, there is a single thoracic pair situated on the second 
thoracic segment on the inflexed portion just in front of the coxae; 
theie are eight abdominal pairs, each situated near the cephalic 
border of the segment. Surface of the body shining, nearly 
smooth on the thoracic segments and on the venter; the dorsum 
of the abdominal segments is marked with numerous shallow 
transverse notches, and a slight dark ridge which crosses the 
segment near the cephalic border, then curves suddenly, extends 
obliquely caudo-ventrad on each side and nearly meets the faint 
impressed line extending across the segment. "The caudal and 
cephalic margins of the first thoracic segment, and the caudal 
margin of the other segments, except the first and last, are 
marked, by numerous fine longitudinal striae. A linear mesal 
depression ending abruptly near the caudal border of each seg-
