200 Descriptio?is of new Ceylon Coleoptera. [no. 2, new series, 



antennal club is composed of 4 joints, the 3 first of which are 

 strongly compressed, the 4th being plump and of the shape of an 

 acorn with its cup, all are strongly ciliated. The thorax is conic, 

 firmly applied to the base of the elytra as in the preceding species, 

 depressed and with 2 pits at the base, posterior margin with 2 si- 

 nuosities. The shoulder-ridges of the elytra are short but rather 

 strongly marked. The tibiae are narrowed, subcylindric and hairy 

 at the apex. Joints 2-3 of the tarsi are subequal, the anterior pair 

 more, the intermediate less contracted. 



39. Scydmaniis graminicola. JV. 



S. gracilior ; long, corp Jlin. Antennae art. 3 et 4, 6 et 7, 9 et 

 10 inter se subaequalibus 5° adjacentibus paulo longiore, 3-7 sub- 

 cylindricis, 8 subgloboso, 9-10 fortiter globosis cum 11° clavam 

 formantibus. Palpi maxill. art. 3° inverte conico, 4° mediocri. 

 Mandibulae apice arcuatae, medio acuminate 1-dentatae, basin versus 

 sensim dilatatce. Thorax obconicus basi depressus, 2-sinuatus et 

 2 foveolatus, rectangulatus. Pedes tibiis elongatis basi apiceque 

 arcuatis. 



Of the usual brown color, legs and antennae lighter, tarsi and 

 palpi quite so, femora nigrescent at the apex, hair-s of occiput and 

 thorax rather long. The former slightly narrowed behind, the head 

 thus of a somewhat rhomboid form. Antennal club composed of 3 

 joints, the 2 first of which are strongly globose, the last being 

 acuminated and slightly cut away on one side at the apex. The 

 mandibles are furnished with an acuminated tooth at the mid- 

 dle, bent at the apex and, what is rather uncommon in this g,, 

 gradually enlarged towards the base. The thorax is obconic, 

 rather longer than broad. The elytra are somewhat more stretch- 

 ed than usual in this group, the rudimentary humeral costa are 

 rather prominent and they are separately rounded off at the apex. 

 Tibiae more or less elongated, slightly bent at the base and apex, 

 at the latter place subcylindric and hairy. Tarsi with joints 2-3 

 subequal, first pair slightly contracted. A sexual distinction ap- 

 pears to be expressed in the length of the tibiae which are less 

 elongated in certain individuals which are at the same time less
