3536. Byraxis bisulcifrons sp. nov. 



Shining, moderately convex; rufo-pieeous, legs fuseous, tarsi and 

 palpi a little jjaler ; scantily elotlie<l with greyisli, elongate and sleiidei-, 

 mostly upi'ight setae. 



Head smaller than thorax, gradually narrowed anteriorly, euivedly 

 nai-rowed behind, the eyes; slightly longitudinally bi-impressed in front, 

 Avith 2 indistinct small interocular fovea, and a central occipital 

 puncture. Eyes situated. behind the middle, rather large, but oidy very 

 modei-ately convex. Thorax about as long as broad, widest and rounded 

 before tlie middle, without any perceptible sculpture. Elytra nearly 

 double the length and breadth of the thorax, gently curvedly narrowed 

 anteriorly, with somewhat oblique shoulders, so that the base hardly 

 exceeds that of the thorax in width; sutural striae well developed 

 throughout, each elytron has some shallow indistinct punctures which 

 almost foi-m three ii-regular series. Hind-body evidently sliorter than 

 the elytra. l)asal segment rather larger than any of the othei'S, which are 

 deflexed. 



Legs mtideiatelv stout ; posterioi' tibiae latlier longer tlian tlie others, 

 slightly cui'ved and tliickened towards the extremity. 



Antennae shorter tlian the head and thorax, with slender setae; basal 

 joint stout, not twice as long as broad, 2nd rather smaller, 3i-d still 

 smaller, 4th also short but distinctly broader than the 3rd; 5th }'emark- 

 ably large, its basal portion transversely quadrate and bi-oader than the 

 4th, its larger apical jiortion subtriangular, strongly but not acutely

 fortunately found two males on the mountains near .Xb'thven (|uite recently : these

3052. Byraxis lewisi. 



M(i1p. — Anterior trochanters distinctly spined. .\retaslcrnum Ijioadiy depressed 

 from base to apex, the cavity with distinctly but obtusely raised sides. Basal ventral 

 segment covered ; 2nd large, medially depressed, with 2 tubercular elevations extend- 

 ing nearly the whole length, and rather widely separated behind ; the 6th with a 

 deep, large, subrotundate central fovea. Ninth antonnal joint somewhat ccmcave 

 miderneath, and with a hook-liUe appendage near its inner extremity — this is not 

 visible from above when mounted in the ordinary manner unless the antenna is twisted.
