 narrow) .., Group A M B L Y T E L I D E s.

 i. Prothorax with two 

 marginal setse on each 



side Genus Amblytelcs. 



ii. Prothorax with one 

 marginal seta on 

 each side (at basal 

 angle) Genus Dy'strichothorax. 



Notes on the preceding table. — As I have no example of any of 

 de Castelnau's species of the genus Teraj^his, it is possible the 

 tabulation given of the Melisoderides may be so defective as to 

 be of little use, for the seventh stria may not be obsolete in the 

 typical species of Teraphis, though it is so in T. ( Drimostoma) 

 hehnsi, SL, the only species of the genus I have. 



De Castelnau's genera Moriodema and Moriomorpha seem not 

 sufficiently distinct to be kept separate, and Moriodema is con- 

 generic with Melisodera; therefore both have to fall out of the 

 list of Australian genera. 



Driinostoma striato-punctata, Casteln., the type of which I have 

 seen in the Howitt Collection at the Melbourne University, is 

 congeneric with the species from New Zealand, which Mr. Bates 

 referred to the Chilian genus Tropopterus, and Mr. Bates was 

 Avrong in suspecting it to be identical with Cyclothorax instdaris,
