Genus Culicada.

Theob., in a totally different group by the " seventh abdominal 

 segment (being) almost wholly yellow scaled, etc." This mere 

 colour variation I have even seen in sylvestris. It comes very

 separate it at once. The description drawn up here is taken 

 from specimens named and bred by Felt and Smith. 



$ . Head with pale creamy narrow-curved scales, golden- 

 brown in front, flat pale lateral scales and very narrow upright 

 brown forked scales; palpi, antennae and proboscis deep brown. 



Thorax deep brown with very small rich reddish-brown narrow-
