Holofype : a (^ in Brif. Mvs. Reg. No. 1914—535. (Presented 

 by The Imperial Bureau of Entomology). 



From a " Yellow and black-billed Toucan," from Colombia, Boca 

 de Ai-guia, Atrato Valley (Dr. A. Balfour, v. 1914). 



Menacantlius halfoiiri is evidently close to Menopon {Men acanthus) 

 exsanguis Paine and Mann, described from a Brazilian woodpecker 

 (Campephilus melannleucvs Gm.). It differs from that species, how- 

 ever, in size, in being much less setose, and in the form of the genitalia, 

 so far as the description allows one to judge (Psyche, XX, 1, p, 19, 

 fig. 20).

THE BRITISH SPECIES OF ANEURUS Cukt. 

 BY DE. E. BERGROTH, C.M.Z.S. 



In 1903 the Swedish entomologist E. Mjoberg described, under 

 the name A. tuberculatus, a new species of Aneurus from the island 

 of Oland in the Baltic Sea, and in 1909 he more fully pointed out the 

 differences between it and A. laevis Fab., the only European member 

 of the genus previously known. The two species have since been 

 found to possess nearly the same geographical distribution, and both 

 of them occur in Grreat Britain. Fabricius described laevis from 

 England, and his well preserved type specimens (two males) are still in 

 Banks's old collection in the British Museum, where I have examined 

 them. They belong to A. tuberculatus Mjob., and this species must 

 therefore bear the name laevis Fabr., whilst the insect described by 

 Mjoberg as " laevis Fabr." must be called A. avenius Duf., of which I 

 have also seen a type specimen. A. avenius seems to be common in 

 England, where the true laevis is a very much rarer insect. A. laevis 

 has been taken near Woking by Mr. Champion, and in the British 

 Museum I saw examples of it from Power's collection, taken by the 

 late George JSTorman. These specimens have no locality label, but 

 there can be little doubt that they are from Scotland, where Norman 

 lived continuously from the time he began to study Hemiptera, 

 collecting chiefly in Perthshire. Yet a corroboration of the occurrence 

 of A. laevis in Scotland is desirable, as this would be the northern- 

 most known locality for the species, apart from the Swedish one. In 

 all faunistic works (Fieber, Puton, etc.) the description of " laevis "
