RHYPAROSOiMIDAE. 423 



3898. Lithocia nigricrista sp. nov. 



Subopa(|Ut\ tusco-testaceous, thorax more rufesceiit, tibiae pale yeliowisli, 

 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 

 ftnely 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 pmictate ; 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 fimiculus not quite as long as the 1st, 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), 6 mm. ; breadth, 2| 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, cjuite 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, attaining the front of the eye, slender 

 near the base, clavate at the extremity. Funiculus 7-articulate. 2nd joint 

 slightly 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 wudth as 

 thorax at the base, subpyriform. Legs moderately elongate, tibiae indis- 

 tinctl)' 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 

 fuie 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 Phri/ni.r>'ft and Pachij- 

 prypnus, wliich latter it most nearly resembles.
