tlie antennae are pitcKy at the apex. The thorax is about 

 equally wide across the front and the base.

L. semicostafiis, sp. nov. Minus nitidus ; minus elongatus 

 minus convexus ; piceo-niger ; labro mandibulis palpis et 

 antennis testaceo-rufis ; capite longitudinaliter canalicu- 

 late ; prothorace longitudinaliter costato pone medium 

 minus fortiter constricto ; ely tris seriatim punctulatis ; in- 

 terstitiis 3° (apicem versus), 5° et 7° costatis. Long, -fl. 



Much more depressed than either of the preceding two ; the- 

 antennae and head scarcely different from the same parts in 

 L. costatipennis ; the thorax (evidently wider in front than 

 behind) with some distinct, though only slightly raised, longi- 

 tudinal cost?e, no evident transverse costae, and the interspaces 

 hardly concave ; the elytra with very distinct rows of rather 

 large punctures ; the interval between the second and third of 

 these rows scarcely raised except near the apex, the intervals 

 between the fourth and fifth and between the sixth and seventh 

 rows finely but distinctly keeled throughout their length. 



The cost?e on the thorax and elytra are very much less raised 

 than in either of the preceding. The almost complete disap- 

 pearance of the costation, in its anterior two-thirds, of the- 

 interval between the second and third rows of punctures on the 

 elytra is a marked character. 



Port Lincoln ; a single specimen under bark of Eucalyptus.

The basal part of the thorax is quite as wide as the front ,-. 

 the raised lines and convex spaces on its surface do not seem to 

 differ much in pattern from those on the thorax of L. costatipennis,. 

 but they are quite faint, and not easy to trace even under a 

 Coddington lens. The elytra are distinctly striated ; each stria 

 has a row of large coarse punctures ; the interstices are decidedly 

 convex, but the alternate ones scarcely more so than the rest. 

 A transverse depression crosses the elytra a little behind the 

 base. The black markings on the elytra consist of an elongate 

 blotch in front of the middle, between the second and fifth 

 strisD, two or three spots near the lateral margin in the front 

 half, the hinder part of the suture, and an irregular fascia 

 which crosses the suture a little behind the middle, but does 

 not nearly reach the lateral margins. Examples thus marked 

 bear a striking resemblance to some of the small species of
