Genus 36. Eutanypus (\)qui]lett 

 Fur Seals aud Fur Seal Islands. 4:341. 1899 

 Closely related to T a n y pus, but the antennae of the female 

 are 8-jointed, of the male 9-jointed, not plumose, the first joint 

 bulbous, about three times as broad as the second; joints two to 

 seven in the female, two to eight in the male, decreasing in length 

 outwardly, the penultimate joint only slightly longer than broad, 

 the ultimate nearly as long as the three preceding joints- eyes 

 deeply emarginate next the antennae, i.alpi four-jointed. Third 

 vein of the wing simple, fourth issuing from the fifth near its 

 base and forking near the middle of the wing, the fifth also fork- 

 ing near the middle of the wing, its upper branch connected with 

 the fourth by a crossvein; small crossvein and first section of 

 the third vein scarcely longer than broad. Type of the genus E.

It appears from this description that the wing venation must 

 greatly resemble that of D i a m e s a , the number of antennal 

 joints and the lack of long antennal hairs distinguishes the male 

 of the genus from D i a m e s a. The females of E u t a n y p u s 

 cannot be distinguished from those of D i a m e s a . Th J third 

 vein spoken of in the above description appears to l>e R.^3 • the 

 anterior fork of the fourth seems to be equivalent to R^^-Vand 

 the posterior fork the same as the media; the fifth is the same as 

 the cubitus. Compare the figure on pl.BG, fig.l3.
