This is another very distinct genus, though with but little 

 resemblance to the last, except in the very broadly pectinated

 body is pilose, and slightly tufted at the extremity in the male ;

 slightly transparent ; the legs are short and downy, and the 

 hind tibiae are armed with two small apical spurs. The

 its palpi. In Pterostoma these organs are of quite unusual 

 length for one of the Notodontidtz, in which Family they are
