strongly posteriorly ; prosternum and head with a few long hairs or sub- 
glabrous, the latter partly granular or mostly smooth, polished, the body 
nearly glabrous, smooth and polished; head light chestnut or brown, body 
dorsally light brown to yellow, ventral plates and legs yellowish, antenne 
the same or darker. 
Antenne rather short (4.4—4.6 mm.); the four basal joints sparsely 
pilose with long hairs, the others closely clothed with finer short hairs ; 
joints all long, the ultimate much shorter than the two preceding taken 
together 
Cephalic plate much longer than wide (5 :3.8 nearly) ; posterior border 
truncate ; impressed with two lateral and a single median sulcus, the latter 
within a more or less evident longitudinal furrow, which is wider and 
shallower anteriorly ; covering the anterior border of the basal plate ; basal 
plate large, subequal to the first dorsal scutum, 2.5 times wider than long. 
Claws of prehensorial feet when closed reaching to the distal portion of 
the first antennal joint; each claw with a small obtuse tooth at base ; coxa 
armed with an inconspicuous obtuse tooth ; sternum wider than long, more 
than twice the outer height of the coxa, anterior border widely sinuate, 
unarmed. 
Dorsal scuta with a single median and two lateral longitudinal sulci, 
which become obscure on a few of the first middle plates but are again 
distinctly impressed caudad ; often a few of the last middle scuta with a 
transversely oval or oblong depressed and darker colored area marked off 
anteriorly and posteriorly by a crescentic impression; anterior prascuta 
very short, gradually increasing in size to the first posterior segments, which, 
are moderate, then more rapidly decreasing to end of body. 
nterior spiracle very large, vertically oval or suboval, a few following 
of the same shape, others round; decreasing in size from the first to the 
eae! caudad becoming very sm

times but one, but more commonly with two, transverse furrows, these on 
each side often broken up into several lines diverging toward the middle 
"t the plate. 
Legs sparsely pilose ; first pair distinctly shorter and more slender than 
those. ag; anterior pairs stouter and shorter than posterior pairs; 
anal lees ied longer than the penultimate, Me swollen, each pro-
