Euto. tinctilatus. Nigrum^ nitidum: caput profunde hisul- 

 cattim, sulcis longitudinalihus antice furcatis: elytra Icsvigata 

 nigra^ later ibus Icste cyaneis ; singula, puncto prof undo versus 

 apicem impresso. (Corp. long. .75 unc. ; lat. .15 unc.) 



Black ; shining : the sides of the elytra are beautifully tinged with 

 blue : the figure is linear, and the habit that of a Clivina : the 

 head is marked in front by two very deep longitudinal impressions, 

 which are anteriorly forked, and posteriorly terminate on the 

 crown : the clypeus is armed with two strong teeth, and between 

 these are two lesser ones : the prothorax is perfectly smooth, 

 square in front, receiving the head ; behind rounded, but still 

 continued and prolonged into a cylindrical peduncle : the thorax 

 has a longitudinal dorsal impressed line, and, together with the 

 elytra, is margined by a distinct lateral carina; the elytra are 

 smooth and shining, each is impressed with a deep fovea dorsally, 

 near the apex : the legs are short, the fore tibiaj being armed with 

 two strong and sharp external teeth, as well as one internal spine, 

 and one apical sharp internal tooth. 



This insect, which is evidently one of the Scaritidcs, inha- 

 bits New Holland, and is a form of very rare occurrence in 

 that island. It was presented by Mr. Walker to the cabinet 

 of the Entomological Club.
