ENTOMOLOGICAL CAEINET. 



RHAGIO SCOLOPACEUS. Leach. Sam. 

 Musca Scolopacea. Linne. 



Asli coloured : head comparatively small : eyes 

 elliptical, large, the hexagons very numerous and 

 minute, when dead of a golden colour : as in most 

 dipterous insects the sexes are easily determined by 

 the distance of the eyes from each other, they are 

 for the most part separated by a very narrow line 

 in the males, and in the females by a broad one : 

 antennae moniliform, terminated by seta : proboscis 

 or trunk exerted when at rest and terminated by two 

 large lips : thorax ash coloured, with three blue 

 black lines ; scutellum large, inflated and with the 

 thorax furnished with strong black seta? : wings 

 with strong and powerful nervures, with spots and 

 maculae varying in size and colour : body long, yel- 

 low and spotted with black : legs a dirty yellow, 

 tarsi black. 



Length of the body £ an inch, expansion of the 

 wings 1 inch. 



Inhabits the trunks of trees and palings, in June 

 and July. 



The insects of this well-marked genus will soon 

 become familiar to the entomologist, by their sud- 

 den, rapid and powerful flight, and their equal and 

 instantaneous settlement on the trunks of trees and 

 palings, generally with the head downwards ; for this 

 mode of attachment their tarsi and claws seem most
