212 C. R. Osten Sacken: Diptera 



The brown of the first basal cell continues along the 

 fourth vein, as far as the posterior crossvein 



eqxies Schin. 

 (Nov. 288.) 

 First basal cell hyaline. 



Wings with a brown margin along the costa, other- 

 wise hyaline; anterior crossvein oblique. 

 Thorax with three yellow stripes 



zonalis Rond. 



(Ann. Gen. VII, 430.) 

 Thorax without such stripes 



marginata v. d.W. 



(Tijdschr.XXIII,179.) 



Wings without a brown margin along the costa, but 



with the crossveins and apex clouded with brown. 



Femora metallic -green; anterior crossvein not 



oblique didi/nia 0. S. 



(Enumerat. 77.) 

 Femora yellow .... flavipes Schin. 



(Nov. 288.) 



II. Scutellum with six bristles; tip of the first vein much more proxi- 

 mal than the posterior crossvein; third and fourth veins not con- 

 verging. 



chalyhea Dol. 



(3 Bijdr. 53.) 

 hataviensis Schin, 



(Nov. 288.) 

 obtrudens Wk. 



(J. Pr. Lin, Soc. Ill, 



116.) 



In this table jlavipes Schin. and obtrudens Wk. are placed hypp- 

 thetically, as regards their venation. The question whether hataviensis 

 Schin. is merely a variety of chalyhea Dol. (Comp. my Enumer. etc. 

 78) is left undecided. The Herinae grandis, limpidipennis and nigro- 

 costata of Doleschall (Bijdr. 3) may also be Stenopterinae; I do not 

 know them. 



Stenopterina calcarata (Syn, Herina calcarata Macq- 

 D. E. II, 3, 307; East Indies). Loew says about it (Monogr. etc. 



III, 47) : „perhaps not a true Stenopterina, but closely related to that
