414 COLEOPTERA. 
Underside black, with reddish-grey scales and slender elongate greyish 
setae. Prosternum widely emarginate. Metasternum medially depressed. 
Basal segment rather longer than the next, depressed along the middle, its 
apical suture sinuate, 5th longer than 3rd and 4th combined, closely 
punctate and setose, rounded behind. 
A rather large species, distinguishable by the broadly rounded dehis- 
cent elytral apices. 
3. Length (rostrum inclusive), 8mm.; breadth, 23 mm. 
Mount Dick, Lake Wakatipu. Unique. Found by Mr. T. Hall amongst 
decaying leaves, at a height of 3,500 ft., on the 17th March, 1914. 
3884. Catoptes robustus sp. nov, 
Robust, oblong, moderately convex, opaque ; nigrescent, antennae and 
tarsi rufo-fuscous; covered with tawny-grey and dark squamae, these 
latter, with the exception of a grey central : spot, cover most of the thoracic 
dise, and a large space on the summit of the posterior slope; the distinet 
decumbent grey setae form series on the elytra. 
Rostrum subparallel, only feebly dilated in front, a fourth shorter than 
thorax, indistinctly carinate. Eyes free from thorax, subrotundate, nearly 
flat. Thorax of equal length and breadth, rounded and widest before the 
middle, more narrowed behind than in front, without perceptible mequali- 
ties, its punctation invisible. Secutellum absent. Elytra oblong, widely 
incurved and slightly broader at the base than the thorax, just double its 
length, narrowed but not quite vertical behind, with divergent but not at 
all prolonged apices ; on each elytron there are 6 dorsal series of moderately 
coarse punctures, 3rd interstices only feebly elevated, 5th subnodose behind, 
the suture broadly yet only slightly elevated near the top of the declivity, 
with a few erect grey setae, but not distinetly crested there. 
Scape stout, bearing greyish setae, just attaining the apex of thorax ; 
basal 2 joints of the funicle stout, equal, twice as long as broad, joints 3-7 
abruptly shorter, hardly any longer than broad ; club elongate. 
Legs moderately elongate ; tibiae slightly flexuous, the anterior minutely 
denticulate inwardly, poste rior corbels with a very narrow space between 
the cilia. 
Underside covered with grey scales and elongate setae. Prosternum 
deeply medially emarginate. Metasternum and hasal segment of about 
equal length, both broadly yet slightly impressed, the latter almost trun- 
cate between the coxae, the next rather shorter , its frontal suture oblique 
at the sides, subangulate in the middle; the 5th as long as 3rd and 4th 
together, with a shallow impression along the middle. 
Ocular lobes moderately developed. Serobes subapical, deep in front, 
directed obliquely towards but not reaching the eyes. 
This, as well as C. dehiscens, cannot remain permanently together in 
Catoptes ; they are not referrable to Inophloeus, but should occupy an inter- 
mediate position. As only single specimens of the same sex are available, 
and as Dr. Sharp described some aberrant species of Brachyolus, which I 
have not seen, it is not advisable to add another to these closely related 
genera, 
Length (rostrum inclusive), 84mm.; breadth, 3 mm. 
Mistake Basin, Canterbury. Unique. Found by Mr. T. Hall on the 
9th October, 1913, amongst dead leaves.
