Longicornia Mulayana. 281 



Olivier described and figured the type species of this genus 

 many years ago, but until Mr. Wallace sent it to England with 

 two new species, it remained otherwise unknown. The genus is 

 remarkable for the almost perfect flatness of the disk of the 

 elytra, which is suddenly bent down at the sides at a right angle 

 (less marked however in P. lima), and the sharp ridge thus 

 formed is furnished with a row of short sharply-pointed spines, 

 and at the sides or above with more spines. These species 

 appear to be very rare ; I have only seen them in my own col- 

 lection. 



Protemnemus scabrosus. 

 Ceramhyx scabrosus, Olivier, Ent. iv. no. 67, p. 8, pi. x. fig. 70. 



P. brunneus, pube squamiformi rufo-grisea tectus ; elytris 

 valde planatis, ante medium paulo transversim excavatis, 

 angulo discoidali acuto, ad latera versus apicem plaga magna 

 rufo-fusca. 



Hah. — Saylee, Dorey. 



Reddish-brown, closely covered with a scale-like reddish-grey 

 pubescence, and with small partially erect hairs scattered amongst 

 it ; head dark brown behind the eyes ; prothorax very irregular, 

 with three especially well-marked tubercles, coarsely granulate, 

 the granules dull black, nearly concealed by the pubescence, and 

 with a deep preapical transverse groove ; scutellum small, angular, 

 transverse ; elytra very flat above, somewhat concave between 

 the base and middle, a few spines on each side of the scutellum 

 forming a kind of crest, and five or six on each side in a line with 

 the discoidal angle, which is furnished with about a dozen of 

 them, another line of spines on the declivity of the side and a few 

 at the shoulder ; the discoidal angle, terminating abruptly beyond 

 the middle, is succeeded by a large, somewhat triangular, brown 

 patch, which extends nearly to the apex ; body beneath and legs 

 with a close brownish-yellow pubescence, speckled with single 

 hairs of a paler colour scattered amongst it as on the back ; the 

 legs, especially the femora, are also marked with numerous short 

 nitid raised lines, in some parts mixed with granules ; this mixed 

 kind of pubescence, together with the lines and granules, are also 

 found on the three basal joints of the antennae, but on the re- 

 mainder the pubescence is uniformly close, and greyish on a pale 

 testaceous-brown surface. 



Length IS lines; of the antennae (^) 33 lines, (^) 24 lines.
