414 Mr. F. Smith's Lists of Species of 



I included this insect in the genus Cryptocerus, with some hesi- 

 tation ; on a more careful examination, and also an examination 

 of another species from Australia, I have satisfied myself that it 

 belongs to the genus Meranoplus. 



Sp. 13. Meranoplus oceanicus. 



M. castaneo-rufus ; capite thoraceque longitudinaliter striatis ; 

 thorace subquadrato, angulis anticis subspinosis ; metatho- 

 race quadrispinoso ; abdomine cordato. 



Worker. Length 2 lines. Chestnut-red ; the eyes black and 

 prominent ; the head narrowed anteriorly and slightly emarginate, 

 rounded posteriorly ; covered with a longitudinal raised striation, 

 the interstices very delicately shagreened. Thorax sub-quadrate, 

 with an irregular longitudinal raised striation, the interstices 

 shagreened ; the anterior margin rounded, the angles acute ; the 

 lateral margins slightly raised, with a tooth a little beyond the 

 middle ; the posterior angles produced into acute spines, and 

 the posterior margin has also two short teeth or spines in the 

 middle. The abdomen heart-shaped, the nodes rugose, the 

 first with a spine on each side, on the thorax, at its insertion ; the 

 head, thorax and abdomen with scattered erect hairs. (PI. XII.
