Broun. — New Genera and Species of Coleoptera. -131 



Antennae filiform and elongate, reaching backwards just beyond the 

 middle femora, 2nd joint more than half the length of 3rd, the latter as 

 long as the 4th. 



In some respects like C . antipodum (532), but differing from it in 

 colour, &c. It is easily separable from C. vitticollis by the impunctate 

 elytra! striae. 



$. Length, 13 mm.; breadth, 3 mm. 



Silverstream. Also discovered by Mr. O'Connor. 



3243. Corymbites sternalis sp. now 



Elongate, rather slender, slightly nitid; elytra fusco-rufous, the 

 thorax of a lighter hue, with its sides and base subtestaceous, the legs, 

 palpi, and basal two joints of antennae testaceous, the other joints 

 fuscous ; rather closely covered with slender yellowish hairs. 



Head very distinctly and closely punctured. Thorax slightly longer 

 than broad, basal angles very slightly divergent, not perceptibly carinate; 

 the surface closely and moderately finely punctate. Elytra with simple 

 apices, the striae nearest the suture rather fine and impunctate, the outer 

 ones distinctly yet rather finely punctured, the punctation of the inter- 

 stices very fine and close. 



Antennae elongate, extending as far as the intermediate thighs, their 

 2nd joint fully half the length of the 3rd, which equals the 4th. Tarsi 

 elongate, their penultimate joint well developed. 



Underside fusco-rufous, closely and very finely punctate, with slender 

 greyish pubescence; flanks of prosternum testaceous, densely and rather 

 finely punctured, saltatorial process fuscous. 



Rather smaller than 532, much more brightly coloured, its thorax 

 differently shaped, not at all straight-sided. 



Length, 10 mm. ; breadth, 2h mm. 



Silverstream. The third species of this genus obtained by Mr. 

 O'Connor within a limited area, and, so far as I know, not occurring 

 elsewhere. 



Group Dasctllidae. 



3244. Atopida basalis sp. nov. Atopida White. Man. N.Z. Coleopt., 



pp. 311 and 1141. 



Elongate, slightly nitid; head and thorax fusco-rufous, elytra cas- 

 taneous with suffused dark marks, legs and palpi testaceous; antennae 

 infuscate from the 4th joint onwards, 2nd and 3rd yellowish, the basal 

 joint rufescent; clothed with decumbent yellowish hairs, those on the 

 elytra coarser and greyish. 



Head large, including the slightly convex eyes, as broad as the front 

 of thorax, closely and rather finely punctate-granulose. Thorax nearly 

 twice as broad as long, base and apex subtruncate, with acutely rect- 

 angular angles, the anterior somewhat depressed, its sides sinuously 

 narrowed behind, in one example strongly rounded at the middle; the 

 sculpture dense, less close at the basal margin, not coarse, punctate- 

 granulose. Scutellum triangular, elongate. Elytra evidently broader 

 than thorax at the base and about four times its length, subparallel, 

 slightly transversely impressed before the middle, irregularly but not 

 coarsely punctured, with a tendency to become subgranulose near the 

 shoulders.
