of maxillary palpi shortest. These characters, except 

 the long paraglosste, agree with Halictus. 

 Viifourea vulgaris, Schenck. — Tongue long and narrow ; 

 paraglossse slender, not half the length of the tongue ; 

 galea tapering, with bristles along its whole length ; 

 maxillary palpi with joint 1 longest, but barely longer 

 than 2, the others shorter, but still long.

This third contribution is a continuation of the two previous 

 papers under the same title [ante, pp. 29 and 213). As the 

 unavoidable synonymical correction to Walker's work pro- 

 gresses (in addition to the same species being described by 

 that author under different genera, his descriptions are fre- 

 quently vague in the extreme), one cannot wonder at Continental 

 entomologists proposing to ignore his work altogether, as was 

 done by feial in 1862 ('Journal of Entomology,' vol. i. p. 481) 

 in relation to the list of Homopterous insects which had then 

 appeared. This course, it is needless to say, cannot be followed, 

 though I have myself felt the great inconvenience — to use no 

 stronger term — of sinking some of my own species when, to 

 employ a parabolic expression, I found that my snipe had been 

 previously described by Walker as pigeons. A more drastic 

 treatment has, however, been advocated for Walker's species 

 of Coleopteia by Bates (Ann. & Mag. Nat. Hist., January 

 1886) and by Dr. Sharp (Trans. Ent. Soc. Lond. 1890, 

 p. 339).
