To the above thirty genera several others might be 

 added ; till however, Helops is fairly grappled with, 

 and treated of in the way that the Melasomata 

 are by Solier ; the above genera may be regarded 

 as giving a very imperfect outline of the various forms 

 composing it. The Helopoidea may be subdivided 

 into the following six families, if not more ; namely, 

 the Helopidae, stelidae, Cisteliadae, Serropalpidae, 

 iEdemeridae, and Rhinosimidae ; Mr. Kirby adds also 

 the Stenochiadae, It will be seen from the above 

 short statement that I do not adopt Solier's other 

 divisions of the Heteromera, as I think they may 

 be greatly improved upon, nor am I disposed alto- 

 gether to abandon the remaining Latreillian divisions 

 named by him Taxicornes, Trachelidae, and Stene- 

 lytra. Of the two arrangements I certainly prefer 

 Latreille's to that of Solier ; both however require 

 to be studied with still greater attention, and if it 

 is not saying too much, require reconstructing 

 afresh. 



Fabrician Species of Helops. 



Sp 3. Metallicus. — Now of the genus Praeugena 

 of Laporte de Castelneau. The characters are de- 

 tailed at page 241 in the Hist. Nat. des Animaux 

 Articules, par Laporte. The true locality is Guinea, 

 and not South America. 



Sp. 4. JEneus. — Now a Camaria of Serville. This 

 insect appears to be the same as Upis senea of 

 Herbst.
