ADENOSCHENDYLA PARAHYBAE, Sp. nov. 
Mostly pale yellowish white, becoming more densely pigmented 
anteriorly, lemon-yellow. Head dilute ferruginous or orange, darker 
in a band immediately caudad of frontal region. Prosternum a little 
paler than the head, with the prehensors much lighter, yellow. An- 
tennae yellow. 
Rather slender with the body considerably attenuated cephalad and 
also very strongly at caudal end. Hairs sparse, of moderate length, 
more numerous caudad. 
Cephalic plate much longer than wide (4:3). Widest caudad, con- 
spicuously narrowed or constricted in frontal region at anterior end; 
anterior border subtriangular; caudal margin slightly concave; sides 
nearly straight from a little in front of caudal corners cephalad to 
frontal region. (Plate 5, fig. 1). 
Antennae strictly filiform as usual. Long, being a little more than 
three times the length of the cephalic plate. Articles mostly long, 
excepting those immediately preceding the ultimate. Ultimate article 
longer than the two preceding taken together. Hairs of articles of 
distal region very short, dense; those of proximal articles conspicu- 
ously longer and more sparse. 
Prebasal plate a little exposed, the cephalic plate not overlapping the 
basal. 
Basal plate with sides straight, strongly converging cephalad; three 
times wider than long. 
Claws of the prehensors when closed about even with the front 
margin of the cephalic plate; claws large and well overlapping; 
robust; articles all unarmed within as usual. | 
Prosternum wider than long in about ratio 7:5; one and a half times 
longer than the outer height of the femur of prehensors; sides con- 
verging from the anterior corners to the caudal and straight excepting 
towards ends; anterior margin sloping a little caudad of directly 
mesad from the ectal ends to the mesal incision, which is shallow, 
laterally strongly chitinized but with no signs of teeth. 
Dorsal plates bisulcate; the sulci on the anterior plates distinct 
caudad as far as a fine transverse furrow a little in front of the caudal 
margin, this transverse furrow being in the form of a pair of concave 
impressions meeting at a cephalically directed angle; a fine median 
longitudinal sulcus also present as may also be one or two less distinct 
ones on each lateral part. Anterior prescuta short, the others in- 
creasing in length to the caudal region where they are moderately long, 
the last ones being again short.
