LIST OF DIHTERA. 595 



Group 3. 



Corpus valde elongatum, parce setosum, vix hirtum. Facies 

 apud epistoma subconvexa. Mystax sat dense setosus. Antennarum 

 articulus lus 2o duplo longior ; 3us lo longior; arista 3o brevior. 

 Pedes sat graciles, spinosi ; tarsi longi. Fcem. — Abdomen thorace 

 fere triplo longius, apicem versus subcylindricum, non compressum. 



Radial vein forked at before balf ils length ; fore fork very 

 slightly curved, joining the subcostal close to the tip of the latter; 

 hind fork almost straight. Cubital curved towards the (irst externo- 

 medial, connected with it by a veinlet at much before half the 

 length of the discal areolet, and with the radial by a veinlet at much 

 before the end of the discal areolet. First exierno-medial almost 

 straight; second hardly curved; third curved, forming an obtuse 

 angle with the praebrachial, which is also curved, joining the fourth 

 far from the border. Subanal joining the anal close to the border. 



Var. (3. Radial vein forked at very little before half its length ; 

 fore fork hardly undulating, joining the subcostal close to the tip of 

 the latter; hind fork slightly curved towards the tip. Cubital 

 curved towards the first externo-medial, connected with it by a vein- 

 let at much before half the length of the discal areolet, and with the 

 radial by a veinlet at much before the end of the discal areolet. 

 First externo-medial very slightly curved; second hardly undulat- 

 ing; third curved, forming an obtuse angle with the praebrachial, 

 which is also curved, joining the fourth far from the border. Sub- 

 anal joining the anal on the border. 



The veiulet between the cubital and the radial is much nearer 

 to the base of the fork of the latter than it is in var. a., and the 

 veinlet between the cubital and the discal areolet is more remote 

 from the base of the latter. 



Trupanea Alamanus, Walk.

 parce spinosi, non pilosi. Mas. — Sexualia parva. Fcem. — Abdo- 

 .rnen apice acuminatum, non compressum nee stylatum. 



Radial vein forked at hardly beyond one-third of its length ;
