Broun. — New Genera and Species of Coleoptera. 423 



Group Cryptophagidae. 



3229. Cryptophagus amoenus sp. nov. Cryptophagus Herbst, Man. N.Z. 



Coleopt., p. 224. 



Minute, elongate - oblong, moderately transversely convex, nitid; 

 castaneo-rufous, legs and terminal joint of antennae fulvescent, remainder 

 of these latter rufous; sparingly clothed with suberect pale flavescent 



setae. 



Head evidently narrower than thorax, not trigonal, the forehead sub- 

 truncate, it is smooth on the middle, moderately coarsely, proportion- 

 ally, punctured at the sides, and with a series of coarse punctures across 

 the occiput. Eyes convex, with distinct facets. Antennae inserted in 

 front of and just below the margin of the forehead, 11-articulate ; basal 

 joint stout; 3rd rather longer than 2nd; 4th and 5th as long as broad 

 and about equal, rather shorter than their predecessor ; joints 6-8 rather 

 smaller and moniliform; 9th rather narrower than 10th, but larger than 

 8th; 10th transverse; 11th conical. Thorax subquadrate, slightly and 

 very gradually narrowed towards the obtuse front angles, its sides mar- 

 ginate but nowhere denticulate; base slightly bisinuate, with nearly 

 rectangular angles, its length and breadth about equal; the surface, 

 relatively, moderately coarsely punctate. Scutellum transverse, smooth. 

 Elytra as broad as thorax at the base, almost twice its length, slightly 

 narrowed posteriorly; with fine sutural striae, their punctation a little 

 finer and more distant than that of the thorax, and becoming finer and 

 less distinct behind. 



Tibiae somewhat dilated towards the extremity, unarmed. Tarsi 

 quadriarticulate, the basal three joints of about equal length, each of 

 these furnished with a slender elongate seta, the terminal rather longer 

 than the others taken together, with distinct claws. 



A single specimen only of this minute insect has been secured. It is 

 not a true Cryptophagus, neither does it agree with any of our Cucujidae, 

 to which group nevertheless it will no doubt be transferred as the type 

 of a distinct genus if other specimens can be obtained.

Makatote. Found amongst leaf-mould collected for me in February, 

 1910, by Mr. W. J. Guinness. 



Group Lathridiidae. 



3230. Corticaria fuscicollis sp. nov. Corticaria Marsham, Man. N.Z. 



Coleopt., p. 234. 



Variegate, head and thorax piceo-fuscous, elytra rufo-castaneous, more 

 flavescent near the shoulders and apex, legs and antennae infuscate, the 

 knees and basal joints of the tarsi paler; pubescence yellowish, scanty, 

 and suberect, most conspicuous near the shoulders and on the posterior 

 declivity; slightly nitid. 



Head nearly as broad as the widest part of thorax, moderately coarsely 

 but not closely punctate. Eyes prominent, occupying almost the whole 

 side of the head from the point of antennal insertion. Antennae as long 

 as head and thorax, with a few fine dark setae; basal joint subpyriform ; 

 2nd not as stout, oviform; joints 3-8 slender, all longer than broad; 

 club loosely articulated, the terminal joint largest, ovate. Thorax a little 

 broader than long, rather wider near the front than elsewhere, its sides 

 moderately rounded; there is a shallow impression near the front and
