4164. Cillenum alacris sp. nov. 



Nitid, moderately elongate and convex, medially narrowed ; fusco- 

 niger, but with the sides of elytra, the palpi, legs, and basal half of antennae 

 more or less pale testaceous or greyish, remaining joints of these last, and 

 the mandibles, somewhat infuscate. 



Head, including the large eyes, as broad as thorax, smooth, with 

 elongate interocular impressions. Thorax of about equal length and 

 breadth, rounded and widest before the middle, gradually, yet more, 

 narrowed behind than in front, with distinct lateral rims and slightly 

 prominent posterior angles, base and apex truncate ; the discal groove 

 rather slender, the base transversely depressed and scored with fine rugae, 

 the fossae small and placed near the angles. Scutellum rounded behind. 

 Elytra twice the length of thorax, slightly broader than it is, and minutely 

 dentiform, at the base, a third wider just behind the curvedly narrowed 

 shoulders, gradually narrowed backwards ; the lateral margins are slender, 

 but the sides are explanate behind the middle and end abruptly as obtuse 

 projections just before the true apices, these are oblique, and each has a 

 short sinuosity close to the side ; dorsal striae moderately deep and finely 

 punctate, but becoming shallow or obsolete on the pale posterior portion ; 

 interstices slightly convex, the third tripunctate ; each elytron has a short 

 scutellar stria. 



This differs considerably in coloration and other details from C. albescens 

 (118) and C. chalmeri (1568) ; this latter has the sides of the wing-cases 

 much less expanded. Dr. Sharp's C. batesi (Trans. Roy. Dub. Soc, Nov., 

 1886) is a synonym of C. chalmeri (Man. N.Z. Coleopt., April, 1886).

 of Mount Albert, who gave me three specimens (all females), informs me 

 that they were very active and difficult to catch.

Sagola Sharp. Man. N.Z. Coleopt., p. 134. 



4165. Sagola dissonans sp. nov. 



Elongate, of interrupted outline, slightly convex, nitid ; castaneo- 

 rufous, antennae and legs paler, palpi and tarsi fulvescent ; clothed with 

 elongate, decumbent and a few upright fulvescent hairs. 



Head nearly as large as thorax, genae not quite straight, hind angles 

 somewhat rounded ; antennal tubercles broad, flat, and subtruncate in 

 front, the slender stria dividing them hardly extends backwards as far as 

 the middle, and is replaced behind by an obtuse carina, the foveae are 

 large, each occupying more than half of the space between the middle 

 and side ; punctation indistinct. Eyes moderately prominent. Thorax of 

 about equal length and breadth, narrowly cordate, widest before the middle, 

 without definite punctation ; the post-median fovea rotundate, moderate, 

 not touching the pair of distinct basal punctures, lateral foveae rather 

 small, not prolonged as far as the middle. Elytra hardly any longer than 

 thorax, much broader behind than at the base, finely and indistinctly
