Subfamily EimMxiNM. 



Genus Peltotrachelus, uov. 



Head continuous with the rostrum, the cj'es comparatively 

 •SQiall and widely separated. Rostrum about as long as the 

 prothorax, its sides slojjiiig outwards from the cariuai 

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

 the apical emargination deep and trianguhir ; the scrobes 

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

 jjressed and with two furrows — one running just below the 

 dorso-lateral carina, the other passing fiom the loMer 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 setaj. 

 Antenna with the scape but little curved, subcylindrical, 

 slightly thickened towards the apex, 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 vibvissse always present. Scu- 

 tellum small. Elytra with the shoulders obliquely rounded 

 and not prominent, the dorsal outline flat or only slij^htly 

 convex, the declivity steep, the apices sepaiately rounded, 

 tlie striae partly hidden by the dense scaling. Leys with the 

 front coxse nearer the anterior margin of the prosternuni ; 

 the femora moderately clavate and with a small tooth ; the 

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

 claws small and free. 



Type, Plafytruc/ielus puhes, Fst. 



The species included in this genus were erroneously 

 attributed by Faust to Platytrachelus, 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 

 Amhlyrrhinus viridamis, Fst. (Stett. ent. Zeit. 1890, p. 74). 

 Platytrachelus differs from Peltotrachelns 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
