I'rothorax with a transverse row of four small tubercles. 

 Second and 4th interstices of elytra with small 

 tubercles ; posterior declivity moderately elongate, 

 apex flattened antiquns, Bohem. 



POROPTERUS ZOPHERUS, 11. Sp. 



Moderately clothed with short roundish brown scales, more 

 elongate towards sides, densest towards apex of elytra, sparse on 

 under surface; femora and tibiae with dense adpressed scales; head 

 and rostrum with sooty-black, the former in addition with brown 

 scales. Ciliation minute, rather sparse, silvery-yellow. 



Convex, cylindric, feebly tuberculate. Head feebly punctate; 

 rostrum coarsely punctate at base, more finely towards apex; eyes 

 moderately granulate, ocular fovea almost concealed, rostrum 

 curved, parallel, scape inserted about one-third from apex, its 

 thickened portion passing muzzle, 1st joint of funicle about as 

 long as 2nd, 2nd not as long as three following combined; club 

 free. Prothorax scarcely longer than wide, flattened; apex feebly 

 produced, rounded, not much narrower than base; ocular lobes 

 rounded; constriction continuous across summit, deepest at sides; 

 sides feebly decreasing to base ; median carina short, feeble, 

 flattened; disc with small granules, transverse row of tubercles 

 just traceable. Scutellum small, triangularly rounded. Elytra 

 wider than prothorax at base, and more than twice as long; sides 

 subparallel to near apex: base bisinuate, with distinct and regular 

 rows of rather large punctures ; posterior declivity abrupt, with 

 a feeble tubercle which is modei'ately distinct when viewed from 

 the side almost at the summit on 3rd interstice. Abdomen feebly 

 convex and punctate, basal segment not twice as long as- 2nd, a 

 feeble longitudinal depression in its middle; intermediates flat, on 

 a level with apical and longer than 2nd and apical. Posterior 

 femora just passing intermediate segments ; tibise straight, the 

 anterior very feebly bisinuate on their upper surfaces; tarsi rather 

 short, 3rd joint rather widely bilobed, 4th not distinctly longer 

 than 1st. Length 12, rostrum 2^; width 4|mm.
