376 COLKOl'TKKA. 



Ventral sciiincTit.s 2-4 increase, ijtli shorter. Gtli obtusely triangular, its 

 actual structure concealed by some ulutiiu)us substance. 



A remarkably tlistin(;t .species. The elongate head, quite oval th(uax, 

 hasally nai'i'owed elytra, aiul lout; liiiid-botly at once distinguish it from 

 tlie type of the genus. 



cJ. Length, 2^ mm. ; breadth, nearly i mm. 



Hollyford, north of Lake Wakati])u. A single individual discovered bv 

 Mr. T. Hall on the 19th February, 1914. 



3826. Sagola unicalis sp. nov. Hdgola Sharp, Gen. Ins. (Wytsm.), Psela- 

 phidae, p. 16. 



Elongate, subdejnes.scd, nitid ; elytra and liind-body parallel, both with 

 numerous elongate, suberect, flavescent hairs, head and thorax more 

 finely clothed ; castaneo-rufous, antennae and legs paler, tarsi and pal])i 

 yellowLsh . 



Head .subquadrate, smaller than thorax, genae almost straight, with 

 obtuse hind angles ; median channel moderately broad and deep, extend- 

 ing to beyond the back part of the eyes, and indistinctly prokmged as a 

 stria towards the base, occiput bipunctate ; frontal tubercles almost hori- 

 zontal, distinctly separated. Thorax cordiform, rather broader than long, 

 its apex narrower than the head ; with a subrotundate median fovea near 

 the base, which is bipunctate, lateral foveae deep but not prolonged to the 

 middle. Elytra oblong, almost double the length of thorax, very slightly 

 narrowed towards the base, finely and indistinctly punctate ; sutural striae 

 deep, with a distinct basal puncture alongside each, dorsal striae inter- 

 rupted, consisting of a basal puncture and elongate impres.sion extending 

 backwards to the middle. Hind-body hardly as long as elytra, similarly 

 punctate, its 1st visibl(> segment evidently shorter than 2nd or 3rd, with 

 minute squamae. 



Legs moderately slender, tibiae straight inwardly, slightly expanded 

 below the middle externally, curvedly narrowed near the extremity. 



Antennae longer than head and thorax, finely pilose ; basal joint stout, 

 twice as long as broad, 2nd subrotundate, as broad as the 1st but only a 

 little more than half its length ; 3rd distinctly smaller than adjoining ones 

 yet quite as long as broad. 4th rather smaller than 5th or 6th ; 7th oblong, 

 considerably enlarged, broader than and about as long as the preceding 

 2 combined ; joints 8-10 laxly articulated, each shorter than 6th, trans- 

 versal ; the terminal subconical, evidently smaller than 7th. 



Underside finely pubescent. Head with a deep groove between the 

 eyes, plane and finely pubescent behind. Meta.sternum convex and of 

 nearly the same length as the abdomen. Basal segment covered by the 

 femora, eiliate behind, the next slightly shorter than 3rd or 4th, 5th widely 

 t marginate, much narrowed behind, as long as the 4th at the sides ; 6tli 

 obtusely pi'ominent in the middle behind and .sinuate towards the sides ; 

 7tli obtu.sely triangular, its operculum oviform. 



The abrupt enlargement of a single joint of the antennae, the 7th, will 

 e xclude this species from every section of the genus ; it nuist therefore be 

 ))laced in another by itself. 



cJ. Length, 2.1mm.; breadth, | nmi. 



Scarclifi, near Mount Algidus ; 16th October, 19J3. A single male 

 found by Mr. T. Hall, and another daniaged .specimen at Moa Basin on the 

 20th of the .same month.
