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 animal8 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 place, 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 being 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.

 carina strongly developed', eyes large, prominent, coarsely granulat- 

 ed', antennae distant at the base; 2 posterior trochanters simple;

S. long. corp. § lin. Antennae art. 3 et 4,5 et 6 inter se subae- 

 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 subaequalibus. 



The insect is of brown color, the antennae lighter, the legs still 

 more and the tarsi and palpi quite so, the 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
