This genus seems to correspond to the section C of the genus Ischnocolus as described 
by Simon (Hist. Nat. Araignees 1, p. 136), though whether all the species referred by Simon 
to this section belong to the Selenocosmiinae cannot be settled without an examination 
of the mouth parts. 
It is perhaps needless to add that Phlogiellus atfords strong support to the view that 
the classification of the Theraphosidae according to the division of the scopulae is purely 
artificial and valueless for bringing allied genera into proximity and for keeping apart those 
that are. not nearly related (See Ann. Mag. Nat. Hist. (6), XVI, pp. 228—230).

d. Body and limbs covered with greyish mouse brown hair, the carapace black beneath. 
Carapace broadly oval, about one fifth broader than long, moderately elevated in the ce- 
phaliec region, its length just exceeding the length of the patella and tibia of the 2 =4 Jeg and less 
‘than those of the 4 ®, its width equal to the length of the 4 ** protarsus. Ocular tubercle 
large, transverse, close to the margin, moderately elevated; eyes of the anterior line very 
nearly straight, subequal, the distance between the median less than a radius and nearly’ twice 
as great as the distance between the medians and the laterals; eyes of posterior line 
smaller than those of anterior and also nearly straight. 
Mandible normally hairy; the external surface inferiorly striate, the fang groove 
armed with an inner series of 9 subequal strong teeth and granular posteriorly. 
Labium and adjacent maxillary process thickly spinulose. 
Sternum a little longer than wide; the sigilla as in Selenocosmia, those of the 1 * leg 
marginal, concealed ; those of the 2"4 a little removed from the margin, those of the 3 = 
considerably removed and separated by a space about equal to the width of the ocular tubercle. 
Palp with lyra consisting of a small oblong cluster of slender close-set setiform apically 
pointed notes, which increase in size towards the oral fringe, some scattered bristles between 
the cluster and the suture; no spines intermixed amongst the hairs of the palp; the tarsus 
short, apically expanded, bilobed and truncate, the bulb with a spiral groove running round it, 
which shows on the inner side as a deep notch; spine with a slight spiral twist, tapering to a 
point, thick at the base owing largely to the presence of a strong keel-like crest which 
follows its outer curvature.
