Oriental Aphodlid Coleoptera. 539 



larger and still more slenderly proportioned, the thorax, ex- 

 clusive o£ the anterior projections, being nearly quadrate. 

 The head is less transverse and less angular than in most of 

 tiie species, and the frontal tubercles are widely separated 

 from those on the vertex. The thorax is coarsely punctured 

 all over, and its central carinie are close together in front, 

 begin to diverge before the middle, and are wide apart behind. 

 Tiie second carina on each side is very broadly interrupted. 

 The front and middle femora are broadly but sharply 

 angulated beneath. 



The genus Syhacodes is closely related to Rhyparus, but Its 

 form is more normal and, except for the thoracic ridges, 

 almost that of Atcenius. The only known species, S. lutu- 

 lentus, Fairm., originally described from Burma, has a wide 

 distribution, and I have seen it also from Siam, Kanara, and 

 the Panjab. M. Rene Oberthiir has kindly enabled me to 

 compare our series with the types, and as M. Fairmaire's 

 description is ambiguous and in some respects inaccurate, I 

 have thought it desirable to give a redescription, based upon 

 the fuller materials at my disposal. 



Syhacodes lutulenfus, Fairm.

This genus has an obvious affinity with Rhyparus, but 

 seems to represent a less extreme degree of specialization. 

 The general contour of the head and thorax are the same, 

 but all the elevated portions of the surface are clothed with
