Mesilla Park, New Mexico, U.S.A., Sept. 25, 189U. XLIX. — Rhynchotal Notes. — III. Heteroptera: Disco-cephalinffi and Pentatominai [part.]. By W. L. Distant. 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 18.S6) and by Dr. Sharp (Trans. Ent. Soc. Lond. 1890, p. 339).
