284 COI.EOPTEIM 



punctured, the legs are stouter; in 2471 the tibiae taper towards the ex- 

 tremity, just the reverse of their structure in S. crassidipes, and the lower 

 surface of the head is materially different. 



Q. Length, 2| mm. ; breadth, | mm. 



Epsom, base of Mount Eden. Unique ; found on the 12th Ecbruary, 

 1912. 



3698. Sagola opercularis sp. nov. 



Subdepressed, elongate, of interrupted contour, shining ; light chestnut- 

 red, legs and antennae paler, tarsi and palpi yellow ; pubescence distinct, 

 yellowish, thicker on hind-body, and with long erect setae there and along 

 the sides of elytra. 



Head rather short and, including the moderately prominent eyes, 

 almost as wide as thorax, obliquely or slightly curvedly nairowed behind ; 

 frontal channel deep and moderately broad, extending from behind the 

 eyes, but becoming narrower and distinctly separating the slightly raised 

 antennal tubercles ; occiput moderately bipunctate. Thorax quite as 

 broad as long, widest and rounded in front of the middle, much narrowed 

 behind ; basal median fossa subquadrate, base bipunctate, lateral foveae 

 deep but hardly reaching the middle. Elytra suboblong, a third longer than 

 thorax, gradually but slightly narrowed towards the base ; sutural striae 

 deep, punctiform at base, where there is a distinct puncture near each, 

 intrahumeral striae prolonged beyond the middle, each bipunctate at the 

 base. Hind-body quite as long and broad as the elytra, basal segment 

 rather shorter tlian following ones, with a few minute brassy scales near 

 its base. 



Legs moderately elongate and slender ; tibiae slightly expanded towards 

 the extremity. 



Antennae somewhat longer than head and thorax, moderately slender, 

 slightly incrassate from the -tth joint onwards; 2nd joint obconical, but 

 little more than half the length of the basal, 3rd very small yet slightly 

 longer than broad ; 4th and 5th oblong-oval, 6th shorter, joints 7-10 more 

 or less transverse, terminal conical, not much longer than the penultimate. 



Underside pubescent. Head with a transverse depression between the 

 eyes and a central flattened elevation behind. Abdomen distinctly but not 

 closely punctate, appearing minutely granulate in some lights, 3rd and 4th 

 segments each rather longer than 2nd, 5th a little shorter than 4th, 6th 

 deeply emarginate, the operculum convex, elongate- oval, broadly grooved 

 along the middle. 



This differs considera])ly from *S'. insuetits, 3521, and other species from 

 the neighbourhood of Methven. It should be placed in Section IX, after 

 S. nitida, 3364, which, however, is larger, with stouter and differently formed 

 antennae and thicker legs, the frontal channel nearly attains the occiput, 

 the intervals between the sutural and intrahumeral striae are at least bi- 

 punctate, and the terminal ventral segments are obviously dissimilar. 

 ,-^. Length, 2 mm. ; bre?.dth, ne?.rly | mm. 



Kakaia Gorge, near Methven. A solitary individual, found by Mr. T. 

 Hall on the 27th December, 1912. 



3699. Sagola brevisternis sp. nov. 



Elongate, slightly convex, not parallel, very glossy ; castaneo-rufous, 

 legs and antennae much paler, tarsi and palpi yellow ; very thinly clothed 

 with suberect, sleiader yellowish pubescence and a few outstanding setae.
