RHTPAROSOMIDAB. 549 



spicuous ones on top of the " declivity, the outer one a little lower than 

 the inner ; the other somewhat nodiform inequalities are subseriate and 

 unequal ; the punctation where visible is coarse and irregularly serial, the 

 declivity is more finely punctured but striate. 



Scape flexuous, moderately stout, clavate at the extremity, without 

 erect setae, implanted at or before the middle and reaching the back of the 

 flat eye, which is distant from the thorax ; basal two joints of funiculus 

 almost equally elongate, joints 3-6 more or less transverse, seventh larger ; 

 club short, ovate. 



Underside piceous, coarsely and moderately closely punctate ; abdomen 

 with obscurely rufescent, depressed, setiform scales, its second segment as 

 long as the first, the frontal suture obtusely angulate in the middle, third 

 and fourth very short, fifth foveate behind. Prosternum .slightly incurved, 

 Mentum subquadrate, palpi uncovered. 



E. irregularis (2391), from the Northern Wairoa, is the nearest species, 

 but its eyes are more convex and placed more on the upper surface, the 

 basal joint of the funicle is shorter than the second ; the thorax is 

 shorter, and the outer ridge near the side extends to the hind angle, 

 though less distinct there than in front. 



Length (rostrum exclusive), 5^-6 mm. ; breadth, 2§-2f mm. 



Glenhope, Nelson. Three individuals obtained by Mr. T. Hall on or 

 about the 10th December, 1914. 



Allostyphlus gen. nov. 



Rostrum as long as thorax, moderately stout and arched. Scrobes 

 foveiform, quite open above, but prolonged as distinct grooves almost to 

 the upper and front part of the eyes, they begin between the middle and 

 apex. Antennae rather slender and elongate ; scape slender, gradually 

 incrassate near the extremity, implanted iDetween the middle and apex 

 and reaching the back of the eye ; basal joint of funiculus almost as long 

 as the next, joints 3-7 slightly longer than broad ; club subovate, narrowed 

 towards its base. Eyes rather small, subrotundate, oblique, the space 

 between them and the thorax equals their own length. Thorax suboblong, 

 slightly wider before the middle than elsewhere, base and apex truncate, 

 without ocular lobes. Scutellum absent. Elytra cuneiform, elongate, of 

 the same width as thorax at the base, medially emarginate there, their 

 outer half obtusely porrect. 



Tibiae mucronate, somewhat arched externally. Tarsi finely setose 

 underneath, second joint transverse, penultimate longer, moderately dilated, 

 excavate above, slightly emarginate at the extremity, entire below. Mentum 

 subquadrate, palpi ex])osed. 



In the European Sft/pJilus the tarsi have spongy soles, their penultimate 

 joint is bilobed, the scrobes differ, and joints 3-7 of frhe funicle are very 

 short. It is allied to Halliella, but the antennal insertion is less pterygiate, 

 situated further forward, and prolonged almost to the eye ; the antennae 

 are more elongate and slender ; the third tarsal joint is less transverse ; 

 and the general form, instead of being pyriform, is almost quite cuneate. 



4083. Allostyphlus jugosus sp. uov. 



Elongate, nearly plane above, the sides and posterior declivity vertical, 

 opaque ; piceous, antennae and tarsi fusco-rufous ; irregularly covered 

 Avith tawny scale-like matter, slender decumbent and coarser erect setae,
