BILOl'IIOTKS. 75 



Elongate narrow. Antcnnte slciuler, the lamcllue springing from 

 the base of the joints long and sh^nder. Thorax fulvous (tinted 

 with grey here and there), straight at the sides, the posterior angles 

 slightly i)rominont and acute ; above with seven ili-detined areolets, 

 the ridges dividing them obtuse. Elytra long, gently convex, each 

 with nine lines of extremely fine elongate punctures arranged in 

 pairs on the back. 



This species differs from M. dispar in having very slender an- 

 tcnnoD ; from M. confonnis in being of a narrower form, in having 

 the thorax narrower with more distinct areolets, the punctures of 

 the lines on the elytra are finer and more elongate, and the alternate 

 interstices are less convex. 



DILOPHOTES. 



Thorax rugosely punctured in front, with a smooth mesial anterior 

 carina. Elytra very slightly narrowed toAvards the apex (where 

 they do not meet at the suture), or parallel, each with three costa), 

 the intervals flat and pubescent. 



The type of this genus is Lijcus (gen. 38) exilis, Waterh. ; but I 

 have associated with it a second species, which diff'ers in having the 

 elytra parallel. Both these species have the first costa of the elytra 

 abbreviated posteriorly. 



Celetes 2)ectinifer, Kiesenw. (Berl. ent. Zeit., xviii. 1874, p. 251), 

 from Japan, must, at least for the present, be placed in this genus. 

 In this species the three costoe of the elytra arc all complete ; the 

 male has the antennse pectinate.

Lycus (gen. 38) exilis, Waterh., Trans. Ent. Soe., 1878, p. 116. 



Flavesecns, pubescens ; thorace postice utrinque impresso, angulis 

 posticis acutis; scutello apice truncate; elytris (apice ipso infus- 

 cato) pubesceutibus, singulis costis tribus ; antennis pedibusque in- 

 fuscatis. Long. 3 lin. 



Hab. Sarawak (Wallace). 



Head with a longitudinal impressed line ; antonnte blackish. 

 Thorax narrowed anteriorly ; the surface rugulose in front, with a 

 smooth mesial line, transversely impressed behind, and with a 

 shallow impression on each side. Elytra a little narrowed towards 

 the apex, where they are not united at the suture ; each elytron 

 with three costsc ; that next the scutcUum is only half the length 

 of the elytra ; the third and fourth nearly reach the apex ; the in- 

 terstices are flat. Legs and abdomen infuscated, tarsi yellowish.
