XXII. Descripiion of a new genus of Coleoptera, belong- 
ing to the family Scaritide. By Dr. HEr- 
MANN BURMEISTER. 
[Read 1st December, 1875. ] 
TuE following description of a new Coleopterous insect 
was communicated by Professor Burmeister, of Buenos 
Ayres, who had named it in honour of Professor West- 
wood on his attaining the age of seventy years, on the 
22nd December, 1875 (adopting for it one of his christian 
names ) :— 
OBADIUS INSIGNIS. 
This new genus, belonging to the family Scaritide, 
was taken on the shore of the River Uruguay, near the 
little town of Concordia in Entrerios; and communicated 
to me as the single specimen found there. The insect has 
the external appearance of Clivina, but differs from that 
genus and all others known of the same family by many 
particular characters, exposed in the following general 
description :— 
Adumbratio generis. 
Antenne ante oculos inserte, breves, 11-articulatee, sub- 
moniliformes; articulo primo elongato, subclavato, sequen- 
tibus tribus longitudine equali; secundo, tertio et quarto 
longitudine decrescentibus, nudis, nitidis ; quarto omnium 
minutissimo ; reliquis longitudine zequalibus, sensim paulu- 
lum crassioribus, tenerrime pubescentibus, pallide pilosis; 
ultimo majori, obtuse acuminato. 
Oculi hemispherici, parum convexi, sed desuper con- 
spicul, posticum versus nodulo genarum suffulti. 
Clypeus, frons et vertex irregulariter rugosi, lateribus 
argute marginatis; pars anterior frontis juxta clypeum 
dilatata, subtumida, sulco longitudinali a clypeo separata, 
superficie inzequali, antice oblique carinata. 
Labrum breve, arcuatum, transversum, angulis rotun- 
datis.
