724 MR. R. E. TURNER ON 



of the segment flattened and distinctly margined laterally, 

 shallowly longitudinally depressed in the middle and sparsely 

 punctured ; the basal segment distinctly less than twice as long- 

 as the breadth at the ajDex. Olypeus broadly rounded or sub- 

 truncate at the apex, not emarginate. Second recnri'ent nervure 

 received at the base of the third cubital cell, almost inteistitial 

 with the second transverse cubital nervure ; thh-d abscissa of the 

 radius a little longer than the second. Pronotum slightly 

 emarginate anteriorly. 



Length 19 mm. 



The details of neuration in the Elidina3 are not reliable for 

 specific differences, often showing slight differences on the 

 opposite sides of the same insect. The really important 

 distinctions in the males of Elis are to be found in the structure 

 of the apical and basal segments of the abdomen.

The type is from Shuckard's collection. I do not know why 

 Smith gave the locality as India or Africa, nor why Colonel 

 Bingham included it in the Fauna of India without any note of 

 doubt. The structure is that of the true American section of 

 Elis, and I look on it as a mere colour-variety, or possibly a local 

 race confined to one island, of E. ephippium Fabr., a West Indian 

 species which I have recorded from St. Thomas, St. John, Antigua, 

 and Porto Rico.

There has been so much confusion in connection with this 

 interesting genus that I think it may be useful to give a short 

 account of the species, which may serve as a basis for a future 

 monograph. Owing to the great differences between the sexes, 

 they were for a long time placed in different families, most of the
