Rev. F. W. Horn on some new Insects collected in Assam. 437 
various particulars. I have not figured it, as true Lamia is well known to 
entomologists. 
EvorLia “*. 
Corpus subdepressum. Antenne lamiæformes ferè ut in Omacanthd. Thorax 
utrinquè spinosus, dorso punctulatus. Ælytra depressa, apicibus 2-spi- 
nosis, spinà suturali minore, lateralibus majoribus. In reliquis cum Lamid 
convenit. 
The above genus I propose to separate from Lamia, as it appears to afford 
ample characters to distinguish it. The antennae in Omacantha differ in the 
different sexes, the terminal joint of the males being considerably larger than 
allthe rest. In true Lamia the last joint is nearly equal in length in both 
sexes : Euoplia therefore is more allied to Lamia Omacantha, which one might 
expect, from a similarity in the general appearance of the insects; the former 
may be considered as the representative of Lamia in Africa. 
Evopuia POLYSPILA. 
Tab. XXX. fig. 6. 
Long. lin. 16. Lat. lin. 53. 
 Cinerea; antennis corpore longioribus, elytris depressis 2-spinosis variisque 
cretaceis maculis aspersis. Corpus infra cinereum, pedibus concoloribus. 
This species inhabits Assam; it is unique in the collection of Mr. R. H. 
Solly. 
To the same genus belong the following undescribed species in my cabinet, 
namely, E. octospilota, sulphurea, Bengalensis, Sinensis, and confusa, all of 
them occurring in the East Indies. I am doubtful if this genus occurs in 
Africa: although it has been recognised in Africa, the entomology of the latter 
country seems to combine the character, and possess some of the leading cha- 
racteristics, of both continents, and yet is remarkable for its peculiar types of 
form; one peculiar instance of which is the anomalous genus Herodon. 
From the Greek eborXia.
