The decided coloration of this species will prevent its being con- 

 fused with any other described form.

DESCRIPTION OF A NEW SPECIES OF STEONGYLOGASTER FROM 



SCOTLAND. 



BY P. CAMEEOlSr. 



The genus Strongylogaster of Dahlbom is divided into two groups, 

 distinguished by the structure of the lanceolate cellule ; -one section 

 having in it an oblique cross nervure, which is absent in the other 

 (and larger) section. So far as I can learn, only two species have 

 been described of the first group, and both appear to be rare in col- 

 lections. Both agree in having the abdomen banded with red, but 

 they differ inter alia in the coloration of the legs. S.JlUcis, Klug, has 

 these appendages for the greater part black, while S. suhjecfus, Evers- 

 mann, has them for the greater part red. As Eversmanu's description 

 of S. suhjectus (Bull. Mosc, xx, p. 44, 3 847) may not be readily ob- 

 tainable, I think it may be useful to give it here.
