Gel/EDs, gen. nov. 



Closely allied to Clirijso(leni.fi, but differs from all the 

 species of that genus \n having two sharply cut impressions 

 at the base of the thorax. Just below the shoulders tlie 

 elytra are acutdy angular. The tarsi arc yellow. 



1 propose this for tiie insect 1 formerly described as 

 Pseuduchrysodtmu (V) JValkeri (Ann. & Mag. Nat. Hist 1892 

 X. p. 411). 



Capt. Kcrrenians has more recently described it as 

 Clirysjdttiia cnpriventris. 



Thv.medes, gen. nov. 



Closely allied to Chnjsodema, but with a form and appear- 

 ance which are suggestive of Psiloptera. Thc^ras: evenlv 

 convex, without impressions, but with a slightly raised 

 median line. 'J'he marginal carina extended to the anterior 

 angle. J^lytra strongly striato-punctate ; the apical margins 

 serrate. Antennae yellow. Tarsi metallic. Metathoracic 

 episterna gradually acuminate posteriorly. 



I propose this generic name for Chnjsodema flavicornis, 

 Saund. 



The only Chnjsodema known to me that at all i-escmbles 

 this is C. hebes, Kerr., but neither in that nor in anv other 

 species does the lateral carina of the thorax extend (juite to 

 the anterior angles as mfavicornis.

Molossus Burnesi, sp. n. 



Allied to the very snl^dl species of Molossus, ]\f. tropido- 

 rhf/nchus, Giay, and M. pyynucus, Miller, but distinguished 

 by the different shape of the biaiii-case. 



Size about as in M. tropidorhynchus and pycjniccus, 

 markedly less than in M. ohscurus, of which there are two 

 specimens in the same collection. Hairs of back exceedingly 

 short, less than 2 mm. in length, as against 3 in M. obscurus, 

 their bases white and their ti|)S brown, the net result being a
