Aglenus brunneus, Gyll. 



A. fusiformi-cylindricus, rufo-castaneus, nitidus, glaber ; capite pro- 



thoraceque distincte, elytris leviter et minus crebre punctatis. 

 Long. corp. lin. |~J. 



Habitat in locis inferioribus Maderse, a Dom. E. Leacock prope 

 urbem Funchalensem repertus. 



Hypophl&us! brunneus, Gyll., Ins. Suec. iii. 711 (1813). 

 Cerylon obsoletum, Steph., 111., Brit. Ent. iii. 98 (1830). 

 Anommatus obsoletum, Shuck., Brit. Col. Del. 27, pi. 33. f. 2 (1840). 

 Aglenus brunneus, Erichs., Nat. der Ins. Deutschl. iii. 285 (1848). 



A. fusiform-cylindric, being a little constricted at the junction 

 of tbe prothorax and elytra, reddish-chestnut, bright, and gla- 

 brous. Head and prothorax closely and distinctly punctured, 

 the punctures having a tendency to become confluent. Elytra 

 much emarginated at their base, causing the shoulders to appear 

 advanced; less deeply, and not quite so closely, punctured as 

 the head and prothorax, the punctures with scarcely any 

 tendency to be disposed in rows. Limbs a shade paler than the 

 rest of the surface. 



The European A. brunneus was first detected in Madeira by 

 Mr. Edmund Leacock (and subsequently by myself in the same 

 locality), beneath some bones and logs of wood in a small out- 

 house, in his garden at the Quinta de Sao Joao, near Funchal ; 

 and it was shortly afterwards captured by Mr. Bewicke amongst 

 vegetable refuse at the Palmeira.
