various particulars. I have not figured it, as true Lamia is well known to 

 entomolog-ists. 



EUOPUA*. 



Corpus subdepressum. Antennae lamiseformes fer^ ut in Omacanthd. Thorax 

 utrinqu^ spinosus, dorso punctulatus. Elytra depressa, apicibus 2-spi- 

 nosiSj spina 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 antennee in Omacantha differ in the 

 different sexes, the terminal joint of the males being considerably larger than 

 all the 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. 



Euoplia Polyspila. 



Tab. XXX. fig. 6. 



Long. lin. 16. Lat. lin. 5^. 



Cinerea ; antennis corpore longioribus, elytris depressis 2-spinosis variisque 

 cretaceis maculis aspersis. Corpus infr^ 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 Hexodon.
