DICRANOMYIA. 



Origin of radial vein considerably before end of mediastinal vein. 



Discal cell open, coalescing with second posterior cell, outer half of disc of 



wing nearly glabrous aquosa, n. sp. 



Discal cell closed (if = D. pubipennis, O.-S., and consequently discal cell 



sometimes open, it coalesces with third posterior cell), outer half of 



disc of wing pubescent pilipennis, Egg. 



Origin of radial vein nearly opposite end of mediastinal vein. 



Subcostal cross vein practically at the end of the mediastinal vein (frons 



silvery, wings spotted) dunietorutn, Mg. 



Subcostal cross vein far before the end of the mediastinal vein. 



Wings either clear, or with a stigma only, or fD. choreaj with a dark 



stigma and the cross veins somewhat clouded. 

 Thorax not shining black ; frons and pleurae dull. 

 Joints of the outer half or more of the antennae elongate, and bearing 



bristles three times as long as each joint (basal joint and rostrum 



yellow) modesta, Mg. 



Joints of the antennae not elongate ; the bristles thereon only about as 



long as each joint. 

 Distinctly ochreous species, even though there may be dark lines on the 



thorax (see also D. chorea), cross veins never infuscated, stigma faint 



or absent. 



Antennae all blackish mitis, Mg. 



Antennae yellowish at base luiea, Mg. 



Species not at all, or very little {D. chorea) ochreous. 

 Stigma distinct. 



Pleurae somewhat ochreous, cross veins usually somewhat infuscated .. 



chorea, F. 

 Pleurae not ochreous, cross veins not at all infuscated ...stigmatica, Mg. 



Stigma absent sericata, Mg. 



Thorax shining black, frons and pleurae silvery morio, F. 



Wings conspicuously spotted, at any rate three distinct spots near costa. 

 Wings with only the three spots near costa conspicuous, mediastinal vein 

 ending nearly opposite one -third the length of the praefurea... 



didt/ma, Mg. 

 Wings dotted along the postical vein, besides numerous other spots ; me- 

 diastinal vein extended slightly beyond the origin of the praefurea... 



ornata, Mg. 



D. AQUOSA, «. «^. ((J$). — Minor, nigro-lrunnea subnitida ; alis glabris im- 

 maculatis prater stigma infuscatum ; ven& mediastinali pone prcefurcce initiitm 

 extensdb, cellulA discoidali apertd. 



Distinct from all European species by its open discal cell, and 

 (except from D. pilipennis) from all British species by the origin of
