rather closely punctured with elongate punctures. Hind 

 body shining black, red at the extremity ; on the upper 

 surface distinctly jjunctvired along the middle and at the 

 sides with oblicpie strige, the basal segment broadly opaque 

 at the base; its under surface shining and with shallow, 

 oblique striae. Legs red. 

 Ega ; a single male. 



6. Lisjnnus cognatus, n. sp. Nigro-piceus, nitidus, 

 fortiter punctatus, antennis piceis, pedibus abdominisque 

 apice summo rufis ; prothorace transverso, basin versus 

 angustato, basi utrinque impresso. Long. corp. 1| lin. 



Antennge short, rather stout ; joints 4 — 6 a good deal 

 broader than long, 7 — 10 strongly transverse. Head 

 rather large, with a very small impression on each side 

 near the front ; the surface shining, moderately closely 

 and finely punctured. Thorax rather strongly transverse, 

 distinctly narrowed towards the base, the surface rather 

 coarsely and closely punctured, and at each hind angle 

 with an ill-defined, not very large impression. Elytra 

 a good deal longer than the thorax, coarsely and closely 

 punctured. Hind body cylindric, but a little depressed ; 

 on the upper surface along the middle segments 2 — 5 are 

 rather coarsely but indistinctly and not closely punctured, 

 at the sides the punctures become obscure oblique strife ; 

 the 6th segment finely and sparingly punctured; the 

 front portion of the basal segment with a moderately 

 broad opaque space at the base. Legs red. 



Ega ; a single individual, which I believe to be a male. 



Ohs. — This species is very closely allied to L. 'punc- 

 tatus, but is a little smaller, and the head and thorax are 

 narrower in proportion to their length, and the impressions 

 on the thoi'ax are narrower in their basal portion, and the 

 antennae are not so stout. 



7. Lispinus modestus, n. sp. Angustulus, subparallelus, 

 piceus, pedibus abdominisque apice rufis ; minus nitidus, 

 crebre sat fortiter punctatus, abdomine segmento 6° sat 

 crebre punctato. Long. corp. 2 lin. 



Antennas short, not much thickened towards the extre- 

 mity; joints 4 — 6 rather stout, the 6th distinctly trans- 

 verse ; 7- — 10 broader than the preceding, rather strongly 

 transverse. Head distinctly narroAver than the thorax, 

 rather closely and finely punctured, and with a distinct
