Euxestus Parkii. 



E. rufo-castanea, nitidissima, glaberrima ; antennis pedibusque paulo 



pallidioribus. 

 Long. Corp. lin. 1-1 1^. 



E. oblong-elliptic, bright reddish chestnut, highly polished, 

 totally free from pubescence, and appearing, except under a high 

 magnifying power, almost impunctate ; but when viewed be- 

 neath a powerful lens, the entire surface will be seen to be beset 

 with small but remote punctures. Prothorax with the hinder 

 margin slightly sinuated. Limbs a little paler than the rest of 

 the surface, being reddish testaceous. 



The discovery of this insect, which so curiously recalls at first 

 sight the common OUbrus liquidus, is due to the indefatigable 

 researches of Mr. M. Park, to whom I have great pleasure in 

 dedicating the species. Three specimens of it, one of which he 

 has presented to the British Museum (the second being in his 

 own possession, and the third having been destroyed for dissec- 

 tion), were captured by him in an ant's nest, in Dr. Lister's 

 garden, at Funchal.

 mine e segmentis .5 composite. Antennee longiusculse (capita pro- 

 thoraceque conjunctim paulo longiores), ante oculos sub margins clypei 

 insertse, apicem versus monilifonnes sed vix incrassatse ; art. 1™° re- 

 liquis baud robustiore, 2'*° brevi, 3"° longinsculo, ultimo subgloboso.

 lidse cornese triangulares, in medio profiincle fisso-sinuatse, una mem- 

 brana aucta necnon ad apicem bifida. MaxillcB bilobse, lobis pubes-
