 Hah. " Nova Hollandia." 



The colour of the thorax and elytra of the type is now nearly 

 testaceous. The thorax is strongly punctured in front, and has a 

 strong discoidal impression. The elytra have seven costte, the alter- 

 nate ones being rather indistinct and irregular ; that next the suture 

 is divided into three near the scutellum. The apex of the elytra 

 and the abdomen are now wanting in the type specimen, which is 

 the only one I have seen.

Hah. Philippine Islands {Cuming). 



Thorax dull yellow, much narrowed anteriorly, the posterior 

 angles diverging and acxite, mesial areolet extending from the base 

 to the anterior margin. Elytra subparallel in the male, consider- 

 ably expanded at the apex in the female ; the first strong costa is 

 joined by its two finer companions nearly at the middle of the 

 elytra ; the punctures in the lines are well defined, rather close, 

 and strongly transverse, 



ENYLUS. 



Antennae compressed, linear. Thorax with a mesial lanceolate 

 areolet. Elytra parallel, each with eight costae ; the fourth and 

 eighth distinct, and extending to the apex ; the second and sixth 

 only distinct at the base, indistinct posteriorly ; the others very 

 narrow and indistinct, the interstices each with a single line of 

 punctures. 



This genus is proposed for a single species which closely resembles 

 some species of Trichalus, especially T. grisens, but has parallel 

 costae to the elytra, 



Enylus segregatus, 

 (Plate XVII, fig. 10.)

 fuscis; elytris singulis costis quatuor. interstitiis crebre punc- 

 tatis. 6 . Long. 2| lin.
