extend caiulo-laterad ami then ventrad, hetween the intermediate and posterior legs. 
Their tips are o]>posite to the penultimate tarsal joint of jmsterior legs. The antennae 
reach to about their middle and are ap|>lied to them. 
Stigmata of ])rothorax visible from ventral aspect; ovate. Tho.se of abdomen 
visible from dorsal a.spect, smaller and rounded oval, those of the first abdominal 
segment partially concealed. 
Setae generally ab.sent, except as mentioned in following; irregular, of medium 
size, and generally originating from di.stinet tubercles or pai>illae. 
From dorsal aspect.-- Head entirely concealed by jwothorax, the latter visible 
for caudal two-thir<ls. The knees and tips of the femora of the first and intermediate 
legs project side by side, from the center of their respective segments; the knees 
of the first pair of legs are slightly caudad of the insertion of the elytra; tho.se of the 
intermediate pair are slightly cephalad of the center of the elytra, and are ailvanced 
farther laterad; more of the femur of the first jiair of legs is visible. 4’he knees of 
the third pair of legs ])roject from beneath the elytra at the third abdomlTial segment; 
the knee alone is visilile. The elytra are visible for at lea.st their basal three-fourths. 
Other ajipendages not visible. The crema.stcr visil)lc for its entire length. 
Prothorax semicinailar in outline, the cephalic edge slightly concave, the lateral 
edges truncate, the caudal edge curved, and convex at median line; surface convex, 
with a thin median furrow. About one-third wider than long. In the disk, on each 
side of and along the median line, the pronottun bears about 13 to 15 rather con- 
s])icuous setae ari.sing from small black tubercles; and the entire margins bear many 
setae, which are inclined to be grouped at the angles. At the dorso-latcral aspect, 
there is also a grouj) of le.ss cons))icuous .setae, of 5 or G. 
Me.sothorax as wide as the jn-othorax, but nearly one-third shorter; nearly three 
times wider than long. The .scuteihun regularly peltate, convex, transver.sely .striate, 
naked. Devoid of .setae. 
Metathorax slightly wider than prothorax, and about twice longer than me.so- 
thorax; with a deep median furrow. Surface glabrous. The thorax about ecpials 
the alMlomen in length; the segmentation is not di.stinet. 
Alxlomen with greatc.st transverse diameter in the third .segment. It tapers 
but slightly cephalad, Init ratlier abruptly caudad, after the 5th segment, reaching a 
])oint in the crema.stcr. Setae are borne on the caudal margins of the segments, 
few mesad, numerous laterad, and thick near the sj)iracles. Segmentation di.stinet. 
Seen from lateral a.spect, segments 1 to 6 are ridged the ridge cushion-like, and with 
a deep impression in the disk. Cremaster fleshy, turned donsad. 
Ventral view . — Head .semicircular, with a thin median furrow, the tips of the 
mandibles reaching a point opposite the insertion of the first pair of legs; front
