Genus tanypus 



Meigen, 1S03, part ; =Ablabcsmyia Johannsen, 1905, and Isoplastus Skuse, 



1889 



Type of the genus is m o n i 1 i s L. All the North American 

 species mentioned by me in Bui. 86 under the name of Ablabesmyia 

 belong here. Besides these s i n u o s u s , t e n e b r o s u s and 

 m i r i p e s (Ccquillett, 1905) , aureus Johan. ( 1907) and 

 f 1 o r e n s n. sp. are members of the genus. 



The following key contains the varieties of the carneus-ornatus 

 group together with the North American species not included in the 

 table on Ablabesmyia given in Bui. 86. In a large series of speci- 

 mens of the carneus-ornatus group [nos. 1-8] it was found that 

 they exhibit such intergradation that it is difficult to define the 

 specific limitations. They differ in the amount and intensity of 

 coloration of body, wings and legs to such a degree that scarcely two 

 specimens can be found that are alike in every particular. 



a Prevailing color of either thorax or abdomen or both, pale 



. b Thorax dull black ; abdomen golden yellow aureus Johan. '07 



bb Thorax yellowish 



c Legs unhanded (carneus group) 



d Thoracic stripes not margined with black 



e Cross vein without cloud var. i. carneus (Schiner) 



ee Cross vein with cloud 



/ Fourth tarsal joint about two thirds of third 



var. 2. carneus (Zetterstedt)
