The species is a reputed native, but in this instance was probably imported as a larva 

 in timber. He also exhibited a uielanic example of Orthosia suspecta, taken by him 

 at Dunkekl last August {vide p. 109 ante). 



Mr. Champion exhibited Cardiophoriis rufipes, Fourc. (uicZep. 227 ante), a, species 

 new to Britain, taken by Mr. Dunsmore near Paisley ; also a British example of 

 Aphodius scrofa, Fab , from the collection of Mr. Dunsmore, of which the exact 

 locahty had not been recorded. 



Mr. W. L. Distant communicated a paper on the geographical distribution of 

 Danais Archippus. The author remarked on the migration of the butterfly from 

 North America (its original home) eastwards to Europe and the Azores, and westward 

 to the South Sea islands and Australia ; and attributed the " means of dispersal " to 

 " winds, currents, and the agency of man." After the reading of the paper a dis- 

 cussion ensued, in which considerable doubt was expi-essed as to the probability of 

 insects being conveyed on floating tin^ber by agency of the gulf-stream or other 

 currents. 



Mr. Douglas read an extract from a letter just received from Dr. John Sahlberg, 

 of Helsingfors : in which he stated, that for six months of last year he was absent 

 on an entomological expedition to the Yenisei, returning through Siberia, and brought 

 back from the extreme North a great quantity of insects, chiefly Coleoptera and 

 Hemiptera, in the determination of which he was now engaged. The insect-fauna 

 of Arctic Siberia agrees very closely with that of Lapland, and he had the pleasure 

 to find, sometimes commonly, several species that he had previously discovered in the 

 extreme north of his own country ; for example, among the Hemiptera, Platypsallus 

 acanthioides and Bathysmatoplionis Reuteri, the latter being the commonest of the 

 Cicada ria in the region. Near the river Yenisei, in places that are annually flooded, 

 he obtained many species, which, although generally not new to science, have not 

 yet been found in Europe. 



He had just completed the examination of the Hemiptera- Heteropter a collected 

 in Siberia, and as they were mostly obtained in the extreme north the number in 

 this group is very scanty, consisting of little more than a hundred species, of which 

 fourteen are new : namely, 1 Aradus, 1 Calocoris, 2 Orthotylus, 1 Acompocoris, 5 

 Salda, 1 Corixa. The species of Salda are large and fine, and were all discovered 

 in the high-north (69° — 70°, 20'), " extra limites arborum." 



He stated also that he had receive a commision to work out the Coleoptera and 

 Hemiptera collected by the four naturalists attached to Nordenskiold's Yenisei- 

 Expedition (of whom Filip Trybom was the entomologist) ; the collection, however, 

 is still in Siberia, and until he had examined it, he would delay any publication, 

 although he had descriptions of the new species ready. 



DESCRIPTIONS OF SOME NEW SPECIES, AND INDICATIONS OF NEW 

 GENERA OF COLEOPTERA FROM NEW ZEALAND. 



BY D. SHABP, M.B. 



The Coleoptera described in this memoir are most of them due to 

 C. M. Wakefield, Esq., who has recently given me a number of very 

 interesting forms, found by him in New Zealand. The following is a 

 list of the species to be described: — Trooositid^ : Leperinafarinosa, 

 Fromanus (n. gen.) depressus, Gri/rioma (n. gen.) fusca, G. dihita. 

 CoLTDiiDiE: Vlonotus discedens, U. integer. EiiizopnAGiNi : Lenax 

 (n. gen.) mirandus. Cucujidje : Brontes pleuralis. Dekjiestidje :
