hardly distinct linear furrow about the anterior third in the 

 shape of a broad angle, the apex of which is tinned backwards ; 

 the surface is punctured all over but morn densely and more 

 deeply along the middle line and in front of the posterior angles 

 as well as behind the apex (Figs. 18 and 19). 



The antennae seem rather long; the right antenna is broken after 

 the 7th joint, the left is entire but does not appear to be normal, 

 and measures 5 mm.; the joints are longer than broad and 

 irregularly beset with bristles. 



Prelabial zone somewhat shorter than broad, with an irregular 

 row of 5 + 5 bristles near the anterior margin, and a " Clypeal- 

 area " of a subquadi ate shape. Sutures of the cephalic pleura? 

 distinct. Labrum divided into three plates ; median plate small, 

 longer than broad, equal to about the twentieth part of the 

 total breadth of the labrum, smooth ; lateral plates more than 

 four times broader than long, furnished with delicately plumose 

 lashes.

F r its margin is parallel to the 



axis of the body, and is furnished with the peculiar spined 

 bristles as described in Pachymerinus froggatti ; the length of 

 these bristles is about 36/x. (Figs. 20 and 21). 



Coxosternal plate of the first maxilla? undivided and destitute 

 of palpi; coxal process distinct, triangular, blunt; the next 

 maxillar joint is provided with a rudimental palpus. 



Coxosternum of the second maxillae divided into two halves on 

 the middle line ; each half is considered as the equivalent of coxa,
