VOCAL £ INSTRUMENTAL MUSIC OF INSECTS. 153 



(S. moroccanus) , destructive on the coast of the Mediterranean 

 and in the Island of Cyprus, did waft across from the vineyards 

 of Es Salt to Jerusalem, probably on the breath of the warm 

 sirocco that inhales from the Syrian desert when the sea breeze 

 that brings the night dew flags. The males of this species have 

 musical combs on their hind legs, and the* prophet Joel would 

 lead us to suppose " their noise is that of a flame of fire that 

 devoureth the stubble." The date of their invasion is the mean 

 year for the return of fewest sun-spots ; the actual date astrono- 

 mers place one or two years later. Stethophyma turcomanum is 

 recognisable from its longer snout and blackish spots ; its males 

 have likewise a musical leg-comb to join in the uproar " when 

 the sun is turned into darkness and the moon into blood."
