LUCANTJS. 57 



Tills species closely resembles L. wc Merman ni. Only a 

 single male, [nobaljly not of full dc;velo|)ment, is at prestiit 

 known. It has the ( lark colour and broad form of tvesfrrtnuuni , 

 but the thorax is rather dilferently shaped. It is very short, 

 strongly, not sliarijly, angulated at the side, with blunt hind 

 angles. The mandible has more than one tooth in addition to the 

 terminal fork. The elyj)eal ])roeess is more sharply jjrodueed 

 and without distinct lateral tubercles, although it is j)ossible 

 that these are to l^e found in larger specimens. The sevi'uth 

 antennal joint forms a process at least as long as the succeeding 

 one.

Dark chocolate-brown, the elytra sometimes a little paler, 

 the legs imiformly dark, the ui)per surface clothed si)arsely 

 and the lower surface rather closely with short yellowish 

 hair. The club of the antenna is composed of four lamella^, 

 the last three long and the preceding one a little shorter. 

 The prosternum is short and rounded behind. 



$. Convex and rather short and broad. The hud is closely 

 rugose, with a rounded ridge on each side behind, the sides 

 nearly straight and parallel in front of the eyes and the front 

 angles fairly sharp. The jrroiwtmii is tinely and closely 

 punctured in the middle and very dtaisely at the sides. The 

 front angles are very blunt, th(> sides gently roiuuled to the 

 lateral angle, which is fairly sharp, and nearly straight to the 

 well-marked hind angle. The dytra are finel>' and closely 

 punctured, densely at the sides and apices. 



(5*. Moderately l)r()iul and compact. The hcdd and j)ronotum 

 are o[)aque, the head Hat above, densely granular, surrounded 

 by a ridge which is nearly straight in front and widely inter- 

 rupted behind. The front angles are sliarj) and duiilicatetl 

 beneath and the eye-ridge is rather sharj)l3- prominent behind. 

 The clypeal process is bluntly pointed and bears a small 

 tubercle on each side. The mandibles are not very long. 

 The 2)ronotv7ii is closely and finely rugose, with distinct 

 punctures only in the middle. The front angles are bluntly 

 produced and the sides feebly sinuate to the rounded lateral 

 angles and nearly straight to the rather sharp hind angles. 

 The .sciitfllnm is clo.sely [)unctured. The elijtra are very 

 tuiely punctured but smooth and rather sliining, except at the 

 sides and apices, which are linely rugidose. Tim front til)ia 

 has a long terminal fork and a very sharj) conical process 

 beneath near the base of the tarsus. The hind tibi;! end in 

 two stnmg ])roces.ses with a blunt angle between them.
