WICKHAM A LIST OF COLEOPTERA. 127 



in distribution. Only one specimen was obtained, and this may 

 possibly have been blown from some vessel bearing freight from a 

 southern port. The genus Dcrmcstes was not met with, though traps 

 for carrion beetles were quite productive of other kinds. Sapriniis 

 litgcns has been found to extend its range into the Lake Superior basin, 

 and the occurrence of Cyllodcs biplagiatus in numbers may be worthy 

 of note. Of the ElateridK it is a pleasure to record the capture of a 

 fine specimen of Megapcnthes rogersii, a rare insect recorded hitherto 

 only from Canada, while the fine development attained by the genus 

 Coryinbites should receive attention. But few Scarabjeida; were seen, 

 only one of which, Aphodiiis hamatus, seems worthy of special remark, 

 from its habit of living in the rotting vegetable mould of swamps 

 rather than in animal excrement, as usual with this genus. The Cer- 

 ambycidoi form nearly a tenth of the whole list ; their great abundance 

 may be directly traced to the forest-covered condition of the district, 

 and the genera and species are, in the main, such as follow in their 

 distribution that of the coniferous forests of the north. The Lepturini 

 are especially noticeable, almost every umbelliferous flower-head having 

 its specimens feeding, while sumach and certain Rosacea^ were also 

 favorite haunts. Certain species seem to prefer certain flowers — for 

 example, Gaiirotes cyanipcnnis was found almost exclusively on sumach 

 blossoms. Many Longhorns, that were not otherwise met with, were 

 cast up alive by the waves, among them the rare Monohammus marmo- 

 rator: Chrysomelidas are rather few in species, and ordinarily in in- 

 dividuals as well, the occurrence of Gonioctena pallida is iiuite charac- 

 teristic of the boreal element in the fauna. Ajithicus pallens is a 

 curious form, with a coloration resembling that of some sea-coast 

 Anthicid?e; it is found under logs in the fine white dry sand of the 

 beaches, and is interesting because of its being found on the sea- 

 beaches of Florida and New Jersey as well. In looking over the list 

 of Rhynchophora perhaps the most striking feature lies in the entire 

 absence of the group Barini. 



A perusal of the list of beetles which follows will show that the 

 majority of them extend to the north and east into the Canadian 

 provinces of Ontario and Quebec, since it is, in almost every case, 

 from these parts of the Dominion that the records which are desig- 

 nated in my notes as Canadian, have come. The Michigan records 

 are mostly taken from Hubbard, and refer chiefly to the lower penin- 

 sula, especially the region about Detroit. Those from Colorado are 

 almost entirely confined to altitudes of above 6,000 feet, and are
