tenth elongate-oval ; they bear a few distinct dark hairs. 

 Thorax strongly transverse, its sides moderately explanate 

 and rounded ; posterior angles not sharply defined, tlie ante- 

 rior obtuse, apex widely incurved; its punctuation shallow, 

 close near the sides, flue and more distant on the disk, 

 which therefore is more shining; the white pubescence is 

 scanty on the middle, but thick at the sides, where there are 

 some long outstanding hairs. Elytra oblong, rather wider 

 than thorax at the base ; near each shoulder there are two 

 very slight paler elevations; their punctuation is coarse, not 

 quite serial, and the intervals between tliem are quite as 

 large as the punctures themselves ; the silvery pubescence 

 has a tendency to form irregular patches, leaving equally 

 irregular bai'e spots. Leys simple ; tarsi elongate, terminal 

 joint as long as the basal four taken together. 



Readily ditferentiated by the black surface and unusually 

 elongate antennae.

Broken River, Canterbury {Mr. J. H. Lewis) ; one. 



Promanus subcostaius, sp. n. 



Oblong, subdepressed, subopaque, f usco-rufous ; the an- 

 tennae, palpi, and tarsi rufo-testaceous. 



Head closely, coarsely, and rugosely punctate. Thorax 

 strongly transverse, of nearly the same width as the elytra, 

 slightly broader at the base than it is in front, the sides 

 moderately rounded, apex widely emarginate, base medially 

 truncate but slightly sinuate towards the obtuse angles, with 

 explanate margins ; the punctuation coarse, close, and rather 

 shallow, but on the middle finer and distant. Scutellum with 

 greyish pubescence. Elytra finely marginate, with nearly 

 vertical sides bearing irregular series of coarse punctures ; 

 the discoidal sculpture consists of about twelve series of 

 coarse punctures, these series very nearly regular ; interstices 

 narrow, nearly plane at the base, but becoming costiform 

 beyond the nnddle ; the pubescence scanty, fine, and incon- 

 spicuous ; the head and thorax bear slender yellow hairs. 



Abdomen finely and closely punctured, with fine greyish 

 pubescence, the segments of nearly equal length. Prosternal 

 process dee[)ly grooved at each side, the middle distmctly 

 carinate between the coxae. Metasternum broadly impressed 

 in front of the contiguous posterior coxae. Maxillary palpi 

 rather elongate, terminal joint not at all broadly securitorm 

 and with a well-marked furrow underneath extending from 

 the extremity to the middle. 



Considerably larger than P. depressus, with closer and 

 coarser sculpture near the sides of the thorax, subcostate
