1. Graphis Parmeliarum, C. K. Parasitic or 



Purmelia tinctorum as rounded brownish spots scattered over the 

 upper surface of the thallus, generally separate, but at times marginal 

 and confluent, slightly raised above the surface of its host, 2-8 mm, 

 in diameter. The lirellre can be observed on these spots as radiating 

 dark-brown lines, not extending quite to the centre of the parasitic 

 thallus, or reaching its circumference, 1 mm. in length, with slightly

 rounding thallus paler near the lirelhe than elsewhere. Spores 

 non-det.

 to those who. have occasion to deal with the indigenous vegetation of 

 the colony in its economic bearings. For a knowledge of several of
