522 COLEOPTERA. 



rather fine punctures. Scutellum distinct, obtusely triangular. Elytra 

 thrice the length of thorax, with seven series of fine but distinct punctures 

 on each in addition to those of the sutural stria. Pygidium invisible. 



Antennae as long as head and thorax, basal joint free, oblong, the next 

 almost us large, but not as long as the almost obconical third, fourth and 

 fifth subquadrate, sixtli transversely moniliform, the.se bear fine erect setae ; 

 seventh, ninth, and tenth abruptly and considerably dilated, transversely 

 quadrate, eighth very short, not quite as broad as adjacent ones, eleventh 

 conical, longer than the tenth but hardly as broad. 



Legs normal ; penultimate tarsal joint very small, entire underneath, 

 excavate above in front for the insertion of the slender fifth, claws simple, 

 the soles finely setose ; basal three joints of the anterior pair moderatelv 

 dilated. 



Underside finely punctate and pubescent, prosternum testaceous, other 

 parts fuscous. 



Labrum transverse, simple. Maxillary palpi with moderately elongate, 

 subacuminate terminal joints, the penultimate subquadrate. Mentum 

 transverse. Prosternum widely emarginate, its flanks unimpressed, the 

 coxae contiguous and situated near the base. Mesosternum medially carnate. 

 Intermediate and posterior coxae only slightly separated. Abdomen with 

 six visible segments. 



More oblong and less convex than preceding species, the dilated antenual 

 joints evidently larger. 



cJ. Length, 2§ mm. ; breadth, 1| mm. 



Woodhen Bend, near Glerhope ; 20th June, 1915. Another of Mr T. 

 Hall's discoveries. Unique, unfortunately. 



Group NiTIDULIDAE. 



Neocercus gen. nov. 



Elongate, subdepressed, pygidium covered. 



Antennae stout, nearly as long as head and thorax, inserted below the 

 edges of the forehead at a little distance from the eyes, 11-articulate ; basal 

 joint thickest, scarcely any longer than broad, third obconical, rather longer 

 than the subquadrate second, both rather thicker than the following ones, 

 which, however, are not slender ; fourth subquadrate, just perceptibly 

 longer than the transversely quadrate joints 5, 6, and 7, eighth slightly 

 smaller ; ninth and tenth transverse, nearly double the width of preceding 

 one, the terminal oblong, slightly broader and evidently longer than ninth 

 and tenth combined. Maxillary palpi very short, stout, penultimate joint 

 subquadrate, the terminal rather longer and tapering towards the extremity. 



Femora pubescent, stout, dilated and grooved underneath at the extre- 

 mity ; tibiae setigerous, straight, gradually expanded, briefly spined at 

 the extremity. Tarsi pentamerous in both sexes, basal three joints of the 

 anterior or in the male densely and finely setose underneath, first largest, 

 transversely cordate, third rather shorter than second, the next narrow and 

 short, fifth slender, as long as the dilated basal three together, with simple 

 claws ; the other pairs less expanded. Fem. : Basal three joints subcordate. 

 only moderately dilated. 



Head as broad as thoracic apex, abruptly narrowed anteriorly ; epistome 

 widely emarginate ; labrum very short, truncate in front. Eves prominent, 

 r<Jtundate, rather large, situated near the base. Thorax transversely quad-
