DILOPHOTES. 75 



Elongate narrow. AntcniiiB slender, the lamellse springing from 

 the base of the joints long and slender. Thorax fnlvons (tinted 

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

 slightly prominent and acute ; above with seven ill-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. clispar in having very slender an- 

 tennae ; from M. conformis in being of a narrower form, in having 

 the thorax narrower with more distinct areolets, the punctures of 

 the lines on the elytra arc 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 towards the apex (where 

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

 the intervals flat and pubescent. 



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

 have associated with it a second species, which differs in having the 

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

 abbreviated posteriorly. 



Celetes pectinifer,'Kie?,eTi.-w. (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 costse of the elytra arc all complete ; the 

 male has the antennae pectinate.

(Plate XYIII. fig. 8.) 



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



Flavescens, pubescens ; thorace postice utrinque impresso, anguHs 

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

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

 fuscatis. Long, 3 lin. 



Hah. Sarawak {Wallace). 



Head with a longitudinal impressed line ; antennae 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 costse ; that next the scutellum 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.
