70 LUCANID^. 



is opaque and strongly and closely j)mi(lured, except in the 

 posterior median part, which is feebly ]>un(tured. The 

 pronoluw is short and broad, strongly narrowed at the base, 

 very finely coriaceous, with fine punctures at the sides. The 

 lateral margin is gently rounded to the lateral angle, which is 

 not very well marked, and concave to the very distinct hind 

 angles. The elytra are opaque at the outer margins, becoming 

 gradually less so towards tlie suture, where they are almost 

 shining. The front tibia is faii'ly slender, minutely serrate 

 externally and feebly toothed, the extremity forked ; the 

 middle tibia has a very strong lateral spine and the hind tibia 

 a feeble one. 



(J. Reddish-brown, with the sides of head and pronotinn, 

 the inner and outer edges of the elytra, the antennae and tarsi 

 darker and the femora and tibiae rather bright red. The head 

 is densely granular and oj^aque, rather sliort, broad in front 

 and narrowed behind the eyes, with a sharp angular prominence 

 on each side before the eye and another less sharp behind it. 

 The clypeal process is transverse, the angles sharply pnxluced. 

 The pronotimi is short and broad, densely granular and opaque, 

 its median part more lightly sculi^tured, with a faint median 

 groove. The front angles are very blunt, the sides irregularly 

 crenulate and feebly rounded to the sharp but minute lateral 

 angle, wliich is situated far behind the middle, and concave 

 to the hind angles, which are very distinct but not acute. 

 The scutellum is smooth. The elytra are long and narrow, 

 very smooth and shining, except at the extreme margins. 

 The middle tibia has a strong spine and the hind tibia has 

 none or a vestige only. 



Variation of the male. Li small males the angles of the 

 elypeal process are scarcely produced and the mandibles are 

 fiat, very gently curved outwards but not arched. They bear 

 only two or three miiuite teeth at the inner edge a little before 

 1 he tip. In larger exam])les the mandibles are compressed and 

 arched in the basal part and more strongly curved. There is a 

 sharj) tooth above at the base, directed oblic|uely backward, and 

 another beneath just beyond the base, direct(xl obli(juely 

 ^orward. The imier edge bears rather ninnerous small tubercles, 

 very irregularly i)laced, from beyond the base to about the 

 middle, followed by three rather larger isolated teeth at nearly 

 e(|ual distances. In large specimens the arching of the 

 mandililes is accentuated, the outward curvature is very 

 strong near the bas(^ and the upper and lower basal teeth 

 are very large, the small tubercles in tlie middh' region are 

 reduced in si/e and extent and the thice tcTininal teeth are 

 enlarged, the middle one the longest and marking the situation 

 of a lathcr abrupt invvaid bending of the extremity of tlie 

 mandible,
