pubescence is very minute. Above densely and minutely punctate, 

 the punctures largest at base and smallest on the apical half of 

 elytra (where they are only visible when the pubescence has been 

 scraped away); meso- and metasternum with minute but distinct 

 punctures. 



Head about as long as the width at the base, between the eyes 

 as wide as the base of elytra, at the base not wider than prothorax. 

 Eyes prominent, coarsely faceted; antenna? inserted immediately 

 in front of the eyes, reaching the basal third of elytra, the joints 

 after the 4th gradually increasing in width to apex, 1st joint about 

 twice as long as 2nd, 2nd somewhat globular, 3rd very short, 

 3rd-5th cylindrical, 6th-8th shortly obconic, 9th-10th transverse, 

 11th conical, as long as 9th-10th combined. Prothorax transverse, 

 base and apex rounded, sides arcuate, an irregular transverse 

 impression in the middle; on each side of the middle of the base 

 an oblique impression. Elytra not twice as long as head and 

 prothorax combined, about one and a half times as long as wide, 

 at its widest a little beyond the middle, a shallow depression near 

 the base not reaching the sides. Posterior legs with the femora 

 very slightly thicker than the others, tibiae dilated towards and 

 emarginate at apex; basal joint of intermediate tarsi as long as 

 the others combined, the claw joint as long as the two preceding 

 it, all the tibia? straight. Length If, width | mm. 



TIab. — Galston. 



The posterior tarsi in my specimen are entangled with the 

 protruding genital organs, and I cannot see them very clearly. 



Syzetonellus humbralis, n.sp. 



(J, Oblong-oval, shining. Head, prothorax, basal joints of 

 antenme and shoulders I'ed; apical joints of antennje brown; elytra 

 and lower surface piceous; legs, prosternum, and palpi testaceous; 

 eyes black. Above very minutely pubescent, densely and minutely 

 punctate, the punctures largest towards the base of the elytra; 

 beneath minutely pubescent, meso- and metasternum leather 

 strongly punctate.
