RHYPAROSOMIDAE. 641 



scale-like matter and, along the middle, with very slender hairs, the setae 

 near the sides and on the legs more distinct, erect, and infuscate, some 

 longer and paler ones form four horizontal tufts on the summit of the 

 posterior declivity, and usually a lateral one just before it. 



Rostrum arched, as long as the thorax, only slightly broader but flatter 

 before the antennal insertion than behind, which, though convex, is not 

 definitely carinate, its apex nude. Thorax oblong, but only slightly longer 

 than broad, a little broader near the front than behind, somewhat narrower 

 at the apex ; disc irregularly moderately coarsely but not very closely 

 punctate, flattened or subdepressed at the base, there is a pair of small 

 apical crests, one before the middle, and another but less distinct one at 

 each side in front. Elytra widest near the posterior declivity, gradually 

 narrowed so as to be hardly any broader than the thorax at the base, 

 which is subtruncate, the shoulders being only very slightly prominent, 

 the scutellar region is depressed, they are almost double the length of the 

 thorax, vertical and narrowed behind ; they are coarsely substriate-punctate, 

 more evidently striate behind ; there is a short elevation on each side of the 

 scutellar region, and another but not very obvious one extends from the 

 shoulder as far as the hind thigh, the external crests on top of the declivity 

 are a little larger and lower than the inner pair ; some minute tubercles 

 are discernible. 



Scape inserted before the middle and reaching the thoracic apex, flexuous, 

 rather slender, gradually incrassate, with a few outstanding setae ; second 

 joint of funiculus quite as long as the basal, joints 3-6 short and sub- 

 equal, seventh very little larger ; club indistinctly triarticulate, ovate. 



Underside dull fuscous, with some fulvescent short setae. Abdomen 

 coarsely but not deeply punctate, its second segment rather shorter than 

 the basal, its indistinct frontal suture rounded in the middle, fifth rufescent, 

 more finely and closely punctured, without any definite impression. 



On comparison with H. longicollis (3902) this is seen to be smaller and 

 more cuneiform, the rostrum and antennae are more slender, the punctation 

 is not as coarse or close, in some aspects the thoracic sculpture appears 

 finely verrucose. The mentum is strongly transverse in front and does 

 not reach the apex, its basal portion is larger. In the type of Halliella 

 (3900) the quadrate frontal portion of the mentum almost attains the apex, 

 the palpi project, so as to be visible from above, and the middle coxae are 

 not as widely separated. These discrepant details almost justify the creation 

 of a distinct genus for this species. 



$. Length (rostrum inclusive), 5J mm. ; breadth, If mm. 



Near Lake Rotoiti, Nelson ; 19th May, 1916. A second specimen, caught 

 on Mount St. Arnaud, at a height of 5,000 ft., on the 15th June, 1916, also 

 by Mr. T. Hall, measures 7 X 2{ mm. ; in it the fifth ventral segment has 

 a longitudinal impression, the vestiture is more fulvescent, and the thorax 

 seems to be free from wart-like inequalities. It is the female of this species, 

 I believe, so far as I can judge at present.

 rufous, tarsi and funiculus paler ; sparingly clothed with decumbent flaves-
