JAN. — MAR. 1857.] Descriptions of new Ceylon Coleoptera. 197 
strong in all individuals. I may mention here that upon some 
of the individuals I found ticks (some g. allied to Ixodes but 
not a Gamasus) fastened, one of them having made a wound 
such as, supposing it to be inflicted at a corresponding place and 
on a proportionate scale, few animals of a higher order, I think, 
would have survived — still this little beetle appeared perfectly at 
its ease. The parasite alluded to had fastened itself right in the 
centre of the forehead and the wound it had inflicted in this, one 
should imagine most dangerous plaije, was a deep hole or pit with 
a callous border. The latter led me to infer that the injury was an 
old one, and the tick bein^ at the time fastened in it (and this so 
firmly that I had some, difficulty in detaching it) I felt sure it 
had been in this position for months. The injury was observable 
under a slight magnifier and I think to compare it to one inflicted 
by a rifle-ball would be greatly underrating its importance.

S. long. corp. J liu. Antennae art. 3 et 4,5 et 6 inter se subse- 
qualibus, obovatis, 7 majore, subgloboso, 8-10 subglobosis, basi 
rotunde— , apice oblique truncatis, cum 11° conico clavam forman- 
tibus. Palpi maxill. art 3° elongato, inverte conico, 4° mediocri. 
Mandibulae tenues, medio acuminate 1-dentatae, basi abrupte dila- 
tatse. Thorax ovato-rotundatus, apice fortius angustatus, basi

Tarsi art. 2-3 subsequalibus. 
The insect is of brown color, the antennae lighter, the legs still 
more and the tarsi and palpi quite so, tie femora are dark towards 
the apex, the head, thorax and suture are occasionally of chestnut 
color ; it is as usual pubescent. The sculpture of the head in this 
and the following species is not, as in the preceding, based upon 
the oblong square or the oval, but rather upon the form of a ball
