shorter than the third, which is slender at the base and triangularly 

 dilated at the apex, fourth to tenth obconical, the fourth and 

 fifth are slightly more triangular than -the others, hut all are slightly 

 broader than long, and not closely set, eleventh slightly longer than 

 the two preceding taken together, slightly. narrower, sub-oblong, and 

 slightly tapering from the base to the rounded apex ; prothorax 

 slightly sloping on each side towards the rounded anterior angle, the 

 sides are plainly sinuate, the basal part, the angles of which are also 

 rounded, is nearly straight, the disk is hardly convex, but the sides 

 .are depressed along the outer margins, the median impressed longi- 

 tudinal line is distinct, the punctuation is very close, and the pubes- 

 cence very short ; elytra wider than the prothorax at the shoulders, 

 a little ampliated in the posterior part, the punctures are deeper 

 than those on the prothorax, and the pubescence seemingly denser, 

 abdominal segments glabrous and impunctate, the second one is 

 produced into a lamina, the apical edge of which is straight, and the 

 angles produced into two sharp parallel spines varying in length 

 and reaching either the apical margin of the third or of the fourth 

 segment, on the penultimate segment are a few faint, minute 

 tubercles, the apical one is not tuberculate, and it is slightly ernargi- 

 iiate in the centre, with the angles sharp. 



Differs from J/. dispar, Boh., by the obconical instead of trans- 

 verse intermediate antennal joints, the impunctate abdomen, and 

 the shape and sculpture of the two ultimate abdominal segments.

Male : Testaceous-yellow, with the head and the fourth and fifth 

 abdominal segments black, antennae, with the exception of the three 

 basal joints, chestnut-brown ; head with a broad transverse depres- 

 sion, sub-carinate on the vertex, and having a conspicuous round 

 sub-rufescent prominence between the antennae, moderately produced 

 behind the large eyes, sparingly punctulate and briefly pubescent ; 

 antennae hardly longer than the head and prothorax taken together, 

 the joints 3-9 are strongly transverse, being twice as broad as long, 

 not closely set, briefly pubescent and setulose, the last one is not 

 quite as long as the three preceding taken together ; prothorax as 

 long as broad, with the anterior and posterior angles moderately 

 rounded, hardly sinuate laterally, deeply but not closely punctured, 

 sparingly pubescent, not impressed laterally along the base, but
