^88 COLEOPfERA 



or less finely and irregularly punctated. Scutellum triangular 1 . 

 Elytra a little wider than the thorax at the base, widest near the 

 middle, narrowed posteriorly ; each elytron with two rather fine, 

 punctured, sutural striae, and two more obvious interrupted ones at 

 the side, the intervening space bearing punctures and irregularly- 

 formed linear impressions. Underside of body and legs pitchy- 

 brown, epipleurse rufescent, without distinct sculpture. 



This species, especially as regards the shape of the thorax, comes 

 near No. 694 ; it is, however, a good deal broader ; the elytral 

 sculpture somewhat resembles that of A. bullatum, though very 

 much finer ; the scutellum is not rounded. The antenna are pubes- 

 cent ; their third joint is not twice the length of the second. 



Length, 5 lines ; breadth, 2 J. 



The species bears the name of its discoverer, Mr. Thomas 

 Chalrner, who sent me a specimen from Dunedin (Flagstaff Hill). 



Group CISTELID-ffi. 



Xylochus (p- 396). 



1406. X. dentipes, n>s. Sub-oblong, moderately convex, 

 nitid, piceous, nude; legs pitchy-red, tarsi fulvous, antennae and 

 palpi red. 



Head contracted behind the eyes, finely and not very closely 

 punctated. Prothorax transversal, base feebly sinuated, sides medi- 

 ally rounded, nearly straight behind, narrower in front than at the 

 base, finely marginated ; more finely and distantly punctured than 

 the head, with two small basal foveae. Scutellum triangular, 

 minutely punctured. Elytra rather broader than and twice as long 

 as the thorax, almost oviform, moderately narrowed apically ; each 

 with a scutellar row of punctures and eight striae, none distinct at the 

 base, the intermediate more or less confluent or obsolete posteriorly, 

 all punctured; interstices but little elevated, finely punctulated. 

 Anterior femora slender at the base, dilated beyond and very evi- 

 dently dentate ; tibia somewhat distorted, so as to appear incurved 

 or incised at the middle ; intermediate and posterior femora simple, 

 tibiae arcuated, ciliated with short fulvous hairs. Underside nearly 

 smooth. Female : All the thighs simple ; front tibiae not incised. 

 Antenna reaching beyond the middle femora, with yellow pubescence ; 

 basal joint shorter than third, second short, third and fourth longest, 

 equal, fifth and sixth each shorter than fourth. Terminal joint 

 of maxillary palpi securiform. 



I believe I am right in considering these two forms to represent 

 the sexes of one species, closely allied to X. tibialis, but differing 

 from it in the armature of the front thighs, and in the absence of the 

 basal protuberance of the femora and rounded median foveae of the 

 thorax. 



Length, 4 lines ; breadth, if.
