RHYPAROSOMIDAE. 423 
3898. Lithocia nigricrista sp. nov. 
Subopaque, fusco-testaceous, thorax more rufescent, tibiae pale yellowish, 
rostrum fusco-rufous, antennae paler; the thorax with 3, the elytra with 
numerous small black crests. 
Rostrum as long as thorax, subparallel, arched, a little flattened and 
finely tricarinate in front, rather strongly carinate behind. Thorax as long 
as broad, widest before the middle, the sides nearly straight behind ; disc 
moderately coarsely and closely punctate ; pale woolly setae form a fringe 
along each side and a pair of apical crests ; on the disc, behind the middle, 
there are 2 small black crests and another in advance. Elytra rather wider 
than thorax at the base, the sinuosity inside each shoulder occupied by the 
thoracic angle, they are nearly twice the length of thorax, and near the 
middle a third broader than it is, they are quite obliquely narrowed, but 
not at all vertical behind; each elytron is moderately coarsely triseriate- 
punctate near the suture, the hind slope more finely and substriate ; 3rd 
interstices elevated at the base and, like the shoulders, covered with 
curled but not elongate black setae, similar setae form 3 distinct dorsal 
crests, and a small pair near the suture; there are others near the sides, 
all the interstices below the top of the declivity bear similar crests, the 
outer ones the largest, and there are others near the extremity ; just on 
top of the declivity fine grey setae form a band between the 3rd interstices ; 
the apices are subacuminate. 
Antennae with dark setae ; scape rather slender near the base, clavate 
at the extremity ; 2nd joint of funiculus not quite as long as the Ist, joints 
3-6 broader, 7th rather more so; club ovate. 
This remarkably distinct species may be readily recognized by its 
numerous black crests. The head has a triangular fovea at the base. 
Length (rostrum inclusive), 6mm. ; breadth, 24 mm. 
Mount Dick, Lake Wakatipu. A single specimen, found by Mr. T. Hall, 
amongst dead leaves on the ground, on the 10th March, 1914. 
Abrotheus gen. nov. 
Rostrum arched, elongate, rather longer than thorax, subparallel, rather 
broader near the base than elsewhere. Scrobes foveiform, quite lateral, 
situated just behind the middle. Eyes obliquely oval, slightly prominent, 
not quite as distant from the thoracic apex as they are from each other. 
Scape inserted behind the middle, attaming the front of the eye, slender 
near the base, clavate at the extremity. Funiculus 7-articulate, 2nd joint 
shghtly longer than the basal, joints 3-6 subquadrate and about equal, 
7th larger, narrowed towards its base. Club short, ovate, indistinctly 
articulate near the extremity. Thorax oblong, base and apex truncate, 
without ocular lobes. Scutellum absent. Elytra of the same width as 
thorax at the base, subpyriform. Legs moderately elongate, tibiae indis- 
tinctly mucronate. Tarsi moderately short, penultimate joint not dilated, 
excavate above, entire, or only feebly emarginate at the apex. 
Prosternum incurved in front, with contiguous prominent coxae. Meta- 
sternum very short. Abdomen elongate, basal segment subtruncate between 
the widely distant coxae, the suture between it and the equally large 2nd 
fine yet distinct and strongly sinuate in the middle, 3rd and 4th very short 
and, together, little more than half the length of the 5th. 
The type of this genus must be located between Phrynixus and Pachy- 
prypnus, which latter it most nearly resembles.
