978 COLEOPTERA 



wider at the middle than in front, a good deal narrowed behind 

 (sinuously), basal angles rectangular ; sides not truly crenate, there 

 being only three or four notches before the middle, and, on each 

 side, eight or ten hairs or tactile setae ; dorsal groove not reaching 

 apex, sometimes falling short of the base ; basal fossae deep, with 

 some punctures near them, situated close to the angles ; the middle 

 indistinctly transversely wrinkled; there are some small punctures 

 in front half-way betw^een the middle and sides, and a few short, 

 feeble longitudinal grooves. Elytra elongate, much wider behind 

 the posterior femora than at the shoulders ; each with four moderate 

 costae, between which are placed two rows of punctures generally 

 accompanied by numerous short, irregular, aciculate impressions ; 

 the sculpture more indefinite behind, and deeper near the sides than 

 at the suture. 



Underside glossy-black, head with fine, short, irregular rugosities, 

 flanks of prosternum more or less punctate. 



Legs stout, middle tibiae with four or five asperities ; the j)osterior 

 a little curvate inwardly (towards the front), apex simple ; the 

 others a little produced at extremity ; tarsi with first four joints 

 (anterior) produced outwardly in front, the intermediate pair more 

 slightly.

Mount Cook, near the Hermitage. Mr. Suter sent me ten speci- 

 mens for examination, under three different numbers, some in rather 

 bad order as regards legs and tarsi. Sometimes the head is more 

 distinctly sculptured ; in other cases the thorax is more or less 

 punctate along the base ; in another example the elytral punctures 

 near the suture are replaced by numerous short, irregular scratch- 

 like marks, similar to those seen in M. sculpturatum. These different 

 forms, after prolonged study, I deem to be only varieties of one 

 species, which should, I think, be placed near the typical one. 



Metaglymma. 



1762. M. asperum, n-s. Oblong, moderately convex ; black, 

 rather dull ; antennae, legs, and palpi rufo-piceous. 



Head moderately broad, not distinctly contracted behind the 

 prominent eyes, without rugae, but bearing two obvious punctiform 

 impressions on its vertex. Antennce stout, not pubescent, having 

 but three or four yellow hairs on each joint. Thorax nearly as long 

 as broad, base incurved, slightly rounded laterally, not abruptly 

 narrowed behind, posterior angles obtuse ; side rims not regularly 

 crenate, appearing as if broken by the punctures in which the intra- 

 marginal hairs are placed ; with a punctated dorsal line, basal fossae 

 well developed, almost circular, with an indefinite connecting im- 

 pression. Elytra moderately broad, narrowed at the shoulders, 

 distinctly punctate-striate, most shallow near the suture, interstices 

 broad, feebly lineated transversely ; the sculpture more irregular 

 behind, where, indeed, several small granular-like elevations occur, 

 the seventh stria with three hairs or setae. Tibice with well-marked 

 apical prolongations.
