214 MR. WESTWOOD ON THE TENEBRIONID^ 



angular projection ; the middle tibiae are nearly straight, slightly dilated at the tip on 

 the outside. The hind femora are serrated behind, with a strong tooth near the tip. 

 The hind tibiae are curved and internally serrated ; they are dilated at the tip, the surface 

 within being very rugose ; on the outside the lower edge of the limb is angularly pro- 

 duced. Each of the elytra has nine punctured striae, with a few punctures placed 

 longitudinally near the suture. Its colour is black. 



Although uncertain at present respecting the sexual distinctions of these insects, I am 

 induced to regard the insect next described as specifically identical with the preceding. 



The entire length is 1 6 lines : the head is nearly 3^ inches long ; the prothorax 3:j 

 long and 4 broad ; the elytra 9| long and 4f wide : the body is very shining and of a 

 pitchy black colour, the elytra being rather more castaneous. The clypeus is widely 

 impressed with small punctures ; the hind part of the head is glabrous, and behind the 

 eyes thickly punctured ; the clypeus is deeply emarginate ; the lateral margins of the 

 head in front of the eyes are much elevated, a deep and curved fossula extending be- 

 tween the raised part across the head ; in the centre this fossula extends a little back- 

 wards ; there is also a shallower and more curved fossula, extending from the hind 

 angles of the eyes. The labrum is quadrate, punctured and cihated along the front 

 margin, which is rounded and entire ; the mandibles are very strong and acute, the right- 

 hand one having a strong tooth in the middle and another much smaller beneath near 

 the tip ; the left-hand one has a smaller tooth in the middle and the extremity divided 

 into three teeth, the two side ones being small and at a little distance from the tip ; the 

 maxillae have the corneous extremity of the inner lobe entire, but oblique ; the maxillary 

 palpi have the last joint slightly securiform ; the mentum is cordate-truncate, and the 

 labium transverse-quadrate with the angles rounded oflp, the middle of the fore margin 

 being slightly indented ; the labial palpi have the terminal joint slightly securiform ; the 

 antennae are three lines long, the last joint oblong with the outer angle rounded. The 

 prothorax is transverse-quadrate, the anterior angles being prominent, the sides very 

 sUghtly rounded ; the posterior angles rounded off, and not extending to the hinder 

 acute margin, so as to appear slightly emarginate ; on the disc in front of the centre 

 are two punctures wide apart. The elytra have nine finely punctured striae on each, 

 with some irregularly placed punctures near the scutellum. The anterior femora are 

 very thick and channeled within, without any tooth near the tip. The tibiae are but 

 shghtly bent, and gradually dilated beyond the middle on the under side of the channel ; 

 the apex being obhquely truncate, the inner angle acute. The middle femora have the 

 indication of a tooth only on the hinder edge near the tip ; the tibiae are nearly straight, 

 and but little dilated at the tip. The hind femora have a strong obtuse projection near 

 the tip within, and the hinder margin is rugose ; the hind tibiae are nearly straight, very 

 slightly and gradually dilated, and with the inside serrated ; the surface rough with 

 oblong punctures. 



The under- side of the body is pitchy brown, and the abdominal segments are simple.
