134 INSDCUTOR INSCITI^ MENSTRUUS 



NEW SPECIES OF JAPANESE CRANE-FLIES 



PART I 



(Diptera, TipuUdce) 



By CHARLES P. ALEXANDER 



The following undescribed species of Japanese Tipulidas 

 were sent to me by Mr. Ryoichi Takahashi, who collected them 

 in the vicinity of Tokyo. I wish to express my thanks to Mr. 

 Takahashi for this and other very valuable crane-fly material. 

 The types are preserved in the collection of the writer. 



Genus ERIOPTERA Meigen 



Subgenus EMPEDA Osten Sacken 



Erioptera (Empeda) japonica, new species. 



General coloration gray ; antennae brownish black through- 

 out ; wings light gray, the stigma a little darker ; Sc^ unusually 

 long for an Empeda; R^ generally parallel to R^ ; cell ist M^ 

 open. 



Female. — Length, 5 mm. ; wing, 5.2 mm. 



Rostrum and palpi dark brown. Antennae brownish black 

 throughout. Head light gray. 



Pronotum gray. Mesonotum gray, the praescutum with 

 three ill-defined brownish gray stripes, the lateral and anterior 

 margins indistinctly flesh-colored. Pleura light gray pruinose. 

 Halteres light brown, the knobs darker. Legs with the coxae 

 gray ; trochanters light brown ; remainder of the legs brown. 

 Wings light gray, the stigma indistinctly darker; veins dark 

 brown; veins with rather long and conspicuous macrotrichiae. 

 Venation : Sc^ ending a little beyond two-thirds the long and 

 nearly straight Rs; Sc^ unusually far from the tip of Sc^^ for 

 a member of this subgenus, Sc-^^ alone being but little shorter 

 than the deflection of Cu^ and longer than that section of 

 i?o-|-3 before r; r on Ro-\-3 at about one-third its length; 

 Ro running generally parallel to R^ and but little shorter than 

 this vein, so that cell 2nd R^ at the wing-margin is about equal 

 to cell i^2 ; cell 1st M^ open ; basal deflection of Cmj at the 

 fork of M.
