Distinguished from all other Ehurim as yet described 
by the total absence of ivory-like spots from the elytra. 
A small oblong smooth callus, which exists in the middle 
of the basal margin, may be taken as the sole vestige of 
these characteristic spots, but this is rufous, like the 
rest of the elytra. The insect is, nevertheless, a true 
Ehuria, and is, in fact, very closely allied to the common 
E. octoguttata (Germ.) of South Brazil, having the same 
coarse punctuation or pitting of the surface of the 
thorax, and a similar but rather more elevated tubercle 
on the crown of the head, like the genus Styliceps.^ The 
* Ehuria octoguttata exists in some collections under the name of E. 
didyma of Olivier. This must be wrong, as Olivier’s insect, according to 
his description, has no lateral spines to the thorax, like E. 4s-maculata of 
Linnasus, and is probably a West Indian species. A fine undescribed 
species of the octoguttata group is the following : — 
Ehuria maculicorniSf n. sp. 
Eobusta, elongata, postice attenuata, supra minus convexa. Caput 
nigricans, fulvo-tomentosum, vertice tuberculo elevate obtuse. Antennse 
( <? ) corpore duplo longiores, dimidio basali infra griseo-ciliatae ; con- 
dylis rufis, articulo basali antice sulcato, nigro, apice extus macula rufa, 
2ndo nigro, caeteris testaceo-rufis, apice nigris. Thorax transversus, nigri- 
cans, fulvo-tomentosus, supra grosse punctatus, tuberculis duobus minus 
elevatis, lateribus medio unispinosis. Elytra postice gradatim attenuata, 
apice truncata et bispinosa ; supra dorso deplanata, apud latera dechvia, 
fere laevia, fulvo breviter pubescentia, maculis parvis flavis vix elevatis, 
baud eburneis, utrinque quatuor, apud basin duabus discretis, externa 
minori, alteris duabus paulo pone medium etiam discretis, interna minori. 
Pedes rufo-testacei, validi, femora compressa, apice nigra, intermedia et 
postica bispinosa.

Another undescribed species differs from all others known to me in the 
peculiarly short and thick basal joint of the antennge. I name it after 
the skilful Entomological traveller, Mr. Eogers, who has recently dis- 
covered it in South Brazil. 
Ehuria Rogersi, n. sp. 
Elongato-oblonga, capite thoraceque vix elytris angustioribus ; fulvo- 
rufa, elytris pallidioribus. Caput genis infra productis subspinosis ; tuberi- 
bus antenniferis apice extus acutis, productis. Antennae ( d ) corpore 
duplo longiores, infra longe ciliatae, articulo basali brevi, crasso, basi extus 
dilatato, subauriculato, antice concavo, articulo 3io supra subcanaliculato. 
Thorax transversus, grosse et dense punctatus, supra tuberculis nigris duo- 
bus elevatis, lateribus spina mediana rufa. Elytra opaca, passim punc- 
tata, breviter setosa, bicostulata, apice bispinosa, spinis nigris, externa 
multo longiori ; supra macula flava eburnea elongata basah, baud elevata, 
extus et postice nigro-marginata, alteris duabus pone medium multo 
longioribus, hnearibus et bene separatis, externa duplo interna longiore 
et hanc antice superante, baud nitidis, antice et postice nigro -margi- 
natis. Pedes unicolores ; femora intermedia et postica spinis duabus 
brevibus nigris, interna majori.
