456 COLEOPTERA. 



rowed before the middle, base and apex truncate, without ocular lobes , 

 the disc moderately closely and coarsely punctured, more finely in front. 

 Soutellum minute or absent. Elytra slightly wider than thorax at the 

 base, nearly twice its length., posterior declivity much narrowed and sub- 

 vertical; each elyti-on with 6 dorsal, distinctly and closely punctured striae, 

 sometimes almost crenate-punctate ; interstices narrow, minutely and 

 distantly punctured, 3rd, 5th, and 7th slightly elevated near the base ; on 

 each elytron, before the middle, there is almost always a broad oblique 

 impression. 



Underside usually piceous, rather closely and coarsely punctate, 2nd 

 abdominal segment less closely, 3-5 more finely, neaily smooth ; 2nd large 

 yet shorter than the basal. 



Eyes free from thorax, lateral, slightly prominent, obliquely oval and 

 quite distinct. Scape implanted before the middle, barely attaining the 

 eye. Basal joint of funiculus stout, the next rather longer than broad, 

 slender at the base, joints 3-6 short, 7th evidently larger; club ovate. 

 Penultimate tarsal joint expanded and sublobate. In the type of the genus 

 the penultimate tarsal joint is scarcely at all broader than the 2nd, the 

 claws are very minute, and the eyes are flat and indistinct. 



Length (rostrum inclusive), 2^ mm. ; breadth, 1 mm.

 leaf -mould in November, 1914. 



Group Lamiidae.

 Coleoptera, p. 600. 



Elongate, narrow, moderately convex, subopaque, variegate ; dark 

 fuscous, the knees and basal 3 joints of antennae rufo-castaneous, 

 remaining joints of the latter fuscous, but testaceous at the base ; tibiae 

 and tarsi testaceous, the former with a dark apical and larger basal spot ; 

 femora somewhat variegate, chiefly castaneous ; the body is covered with 

 inconspicuous, depressed, slender, ashy pubescence mingled with grey, 

 which last forms some spots on the hinder-part of the el}^tra, the sides near 

 the extremity, however, are pale testaceous ; on each side of the thorax, 

 behind the middle, there is a pale round spot, there is a cordiform one on 

 the middle of the apex, and at the middle t)f the base another of the same 

 chocolate hue as the scutellum. 



Head unimpressed and coarsely punctate above, vertical in front. 

 Thorax of equal length and breadth, moderately rounded and widest at 

 the middle, without inequalities, coarsely punctured. Elytra elongate- 

 oval, gradually sloping and attenuate from the hind thighs backwards, of 

 the same width as the thorax at the base, fully twice its length, but hardly 

 at all broader than it is in the middle ; their basal half is coarsely and 

 irregularly punctate, the hinder portion, of each, has a duplicate series of 

 ec{ually coarse, distant punctures extending almost to the apex ; on each 

 elytron a distinct costa extends nearly half-way along the middle of the 

 basal half ; in addition to the ordinary pubescence they bear numerous 

 dark, erect, rather short and slender setae. 



Antennae with fine pubescence and pale setae ; they attain the top of 

 the hind declivity, their elongate 3rd joint almost reaches the base of the 

 thorax, the 4th is slightly longer than the next. Legs rather elongate.
