Subfamily Eremninm. 



Genus Peltotrachelus, nov. 



Head continuous with the rostrum, the eyes comparatively 

 small and widely separated. Roslrunt about as long as the 

 prothorax, its sides sloping outwards from the carinse 

 bounding the median, area, the gense more or less dilated, 

 the apical emargination deep and triangular ; the scrobes 

 apical and short, visible from above ; the lateral areas im- 

 pressed and with two furrows — one running just below the 

 dorso-lateral carina, the other passing from the lower corner 

 of the scrobe to the lower margin of the eye ; the buccal 

 aperture extremely oblique and much longer than the lower 

 surface of the rostrum, the mentum bearing only two set^e. 

 Antennce with the scape but little curved, subcylindrical, 

 slightly thickened toAAards the a))ex, and reaching beyond 

 the front margin of the thorax; the funicle variable ; the 

 club narrowly spindle-shaped. Prothorax transverse, the 

 base deeply bisinuate and broader than the apex, the ocular 

 lobes developed or not, but vibrissse always present. Scu- 

 tellum small. Elytra with the shoulders obliquel}^ rounded 

 and not pi'ominent, the dorsal outline flat or only slightly 

 convex, the declivity steep, the apices sepaiately rounded, 

 the striae partly hidden by the dense scaling. Legs with the 

 front coxse nearer the anterior margin of the prosteruum ; 

 the femora moderately clavate and with a small tooth ; tlie 

 tibiffi simple, the corbels of the hind pair quite open ; the 

 claws small and free. 



Type, PlatytracJiehis pubes, Fst. 



Tlie species included in this genus were erroneously 

 attributed by Faust to Pla/ytrachelus, Schh., owing to his 

 having wrongly identified the genotype, P. pistacinus, Boh. 

 Some years ago, through the kindness of Dr. Taschenberg, 

 I was able to examine the type of that species, which is in 

 Germar's collection in Halle ; it proved to be identical with 

 AmblyrrMnus viridanus, Fst. (Stett. ent. Zeit. 1890, p. 74). 

 Platytrachelus differs from Peltotrachelus principally in the 

 structure of the rostrum, which has the median area broad 

 and the sides vertical ; the scrobes are therefore quite 

 invisible from above and extend backwards for more than 

 half the length of the rostrum. The only other species of
