182 Mr. G. C. Champion on the 



sparsely, finely, the flanks of the prothorax coarsely, punc- 

 tate. Rostrum short, stout, widened outwards, feebly or 

 obsoletely 5-carinate. Head foveate in the middle between 

 the eyes. Antenna? with joints 3-7 of the funiculus short, 

 1 and 2 elongate. Prothorax transverse, rounded or feebly 

 sinuate or subangulate at the sides, narrowed behind, uneven, 

 the two depressions on the anterior portion of the disc separated 

 by a raised median line. Elytra elongate, gradually narrowing 

 from about the middle, and broadly produced at the apex, the 

 apices conjointly rounded; with series of coarse shallow 

 punctures placed in shallow striae, the interstices somewhat 

 convex; each elytron with two oblique ridges on the disc 

 beyond the middle (extending from the fifth interstice to near 

 the suture, the anterior one inconspicuous or evanescent, the 

 subapical one sharply raised and terminating in a prominent 

 tubercle on the interstices 2 and 5), and a large subtriangular 

 tubercle before the tip. Ventral segment 1 with a broad, 

 deep, transversely rugose excavation in the middle. Tibiae 

 strongly sinuate within. 



? . Broader ; the elytra more rounded at the sides, with 

 the subapical tubercles larger and longer, the inner one on 

 the second oblique ridge produced into a long spiniform process 

 on each side of the suture, the apices distinctly caudate. 

 Tibiae less sinuate within. 



Length (excl. head) 7-10, breadth 3-1^ mm. ( £ ? .)

Enderlein apparently did not know the ? of this species, 

 if it has been correctly identified by me. His figure {<$) is 

 apparently inaccurate, and the insect is here redescribed 

 from a series of twenty examples — eleven males and nine 

 females. The sexual difference in the development of the 

 elytral tubercles is remarkable, these being longer and larger 

 in ? than in £ : a somewhat similar peculiarity has been 

 observed in the Patagonian genus Sysciophthalmus, Heller 

 (190ti). L. {Ely trog onus) varicosus, Blanch., from Port 

 Famine, to judge from the figure, may be an allied form*.

 by the artist employed by Blanchnrd.
