580 MAJOR E, E. AUSTEN ON THE 



middle femora is represented by a blunt triangular projection ; 

 hind legs with a veiy small, somewhat blunt and triangular, sub- 

 femoral spine ; terminal spine on hind femora large, long (1 mm. 

 in length) and sharp ; length of hind femur (exclusive of terminal 

 spine) 15-6 mm.; hind femora distinctly thickened towards distal 

 extremity, clothed with fine, short, blackish hair, which is longer 

 on flexor surface and, owing to greater density, especially notice- 

 able between subfemoral spine and tip, distal extremities of 

 extensor and posterior surfaces clothed mainly with bright, 

 appressed, russet-coloured hair; hind tibise thickly clothed with 

 fine, black hair, longer than elsewhere on extensor surface, where 

 it forms a conspicuous fringe; femora reddish-brown, darker 

 towards distal extremities, tips of hind pair reddish-brown ; front 

 tibiie russet-coloured, clothed on flexor surface with short, 

 olistening, ochraceous-tawny hair; middle tibiai russet-brown, 

 clothed for most part with dark brown hairs ; hind tibite black ; 

 first segment of tarsi buff-yellow, extreme tip brown ; remaining 

 segments of front tarsi sepia-coloured, second segment, except 

 distal third, and extreme bases of following segments cinnamon- 

 buft', last three segments of front tarsi clothed above with dark 

 brown hairs, tip of last segment and distal angles of preceding 

 ^segments clothed with bright ochraceous-tawny hairs ; second 

 seo'inent of middle tarsi cinnamon-brown, darker at distal 

 extremity, last three segments of middle tarsi dark brown, clothed 

 above with similarly coloured hair, tip of last segment clothed 

 with tawny hair; last four segments of hind tarsi blackish-brown, 

 second segment paler at base ; claws orange-cinnamon or russet, 

 their tips black ; pulvilli and empodia ochraceous-tawny.

In the 5 sex, at any rate, the handsome species described 

 above, although at the first glance presenting a certain superficial 

 resemblance to Pantophthalmus (Acanthomera) chuni Enderl. 

 {vide supra), is distinguishable inter alia owing to the pallor of 

 the front (frons) and of the dorsum of the thorax ; the reduction 

 in the striping of the latter as regards the median longitudinal 

 stripe and the distal extremities of the paired dark stripes; and 

 the shorter, much moi'e densely hairy and consequently apparently 

 stouter hind tibife. In the case of the type, at least, of P. con- 

 spicabilis, as compared with the specimen of P. chuni referred to 

 on p. 576, the lateral silvery-white spots on the dorsum of the 

 abdomen are blunter and rounder. 



This species is in any case closely allied to, and may ultimately 

 prove to be identical with, Pantophthalmus kerteszianus {Acan- 

 thomera kertesziana) Enderlein, described (Zool. Anz., Bd. xliv. 

 no. 13, p. 578, July 28, 1914) from two ? $ from Peru, in the 

 Museums of Budapest and Stettin. Since, however, Endei-leiu 

 (t. cit. p. 579), in describing the wing in P. kertesziamcs, says 

 that the " basal fourth and a large spot on the anterior margin " 

 are " pale ochreous," it seems wiser, provisionally at any rate, to 

 regard P. conspicahilis as distinct.
