I SHOULD not have relinquished Latreille's generic name 

 Asindulum had he not by some accident described (in his 

 Histoire Naturelle, 1. 14, p. 290, and in his Genera Crustaceo- 

 rujn, Sj-c. t. 4, p. 261) and figured (in the latter work, tab. 15, 

 f. 1.) an insect for the type which appears to be more allied to 

 the Empid(E, having an elongated proboscis inflected under 

 the breast, "Proboscis elongata, sub pectore inflexa," &c. 

 which would exclude it from the Tipulida, none having a long 

 proboscis excepting Culex and Anopheles, and in them it is 

 porrected. 



Platyura is distinguished at once from the neighbouring 

 genera by the transverse nervure at the apex of the wings, and 

 many of them by their depressed abdomens. With their habits 

 and economy we are unacquainted : it is supposed they live 

 upon fungi. The following species are in Mr. Stephens's 

 cabinet. 



1 P. atrata Fab. 



2 lineata Fab. 



a laticornis Meig. pi. 8./. 1 9—2 1 . 



4 rufipes Hgg. 



5 semirufa Meig. 



6 nemoralis Meig. 



7 flavipes Meig. 



8 cingulata Steph. MSS. 



9 ochracea Meig. 

 10 discoloria Meig. 



Of these there appears to be only one figured. Our species, 

 a female of which is represented, is not uncommon in the 

 neighbourhood of London; I have met with it in Coombe 

 Wood and upon paling near Kilburn, in the early part of 

 June of the present year. Some of the species are much 

 larger, and far more rare. 



Poa rigida (Hard Meadow-grass) accompanies the insect.
