Eetssamena, nov. gen. 



G-en. PolimetcE (Pascoe), necnon JRhopaloscelidi (Blessig), 

 affinis. Corpus valde elongatum, parum convexuai, subtiliter 

 adpresso-pubescens, erecte setosum. Caput exsertum, inter 

 antennas profunde sulcatum ; tubera antennifera separata, diver- 

 gentia sat elevata ; frons lata et brevis : oculi grosse granulati, 

 lobis inferioribus latis. Antennae elongatse, filiformes, infra 

 ciliatse ; scapus oblongo-conicus quam articulus 3 brevior, 3 et 4 

 elongatis subaequalibus, 5-11 gradatim brevioribus. Thorax 

 cylindricus, basi transversim depressus, medio paullulum dila- 

 tatus, tuberculo mediano breyissimo, obtuso vel acuto. Elytra 

 maxime elongata, postice angustata, apice oblique truncata, dorso 

 simplici vel ante medium utrinque tuberculo spiniformi. Pro- 

 sternum arcuatum, mesosternum sat latum, antice declive. 

 Acetabula antica angulatim biantia; intermedia subclausa. 

 Pedes modice elongati ; femora gradatim parum clavata, poste- 

 riora brevia ; tibiae intermedige elongatse graciles, extus medio 

 conspicue sinuatse ; tarsi posteriores elongati, art. primo caeteris 

 3 conjunctis sequali. 



Allied to Polimeta (Pascoe), and, like that genus, having the 

 elytra sometimes with and sometimes without two long spine- 

 like tubercles on the disk. It differs, however, in the upper 

 part of the forehead, which in Polimeta forms a raised transverse 

 elevation produced by the coalescence of the antenniferous 

 tubercles. The genus is allied, on the other hand, to Bhopaloscelis 

 in all essential characters. 



Eetssamena sapebdina, n. sp. 



Nigra, pube adpressa fuscescenti-grisea vestita, erecte nigro- 

 setosa, antennarum articulis 3-11 basi albo-testaceis ; thorace 

 sparsim nigro-piperito, tuberculo mediano vix elevate, obtuso ; 

 elytris sparsim setifero-punctatis, punctis nigro-marginatis, fas- 

 ciisque duabus nigris, prima latiori paullo post medium, secunda 

 angustiori undulata ante apicem, dorso iuerml, apice dehiscea-
