SCOLYTIDA — CALANDRID/E. 195 



XCVIIL Genus HYLURGUS. Lat. 



(261) 1. * Hylurgus rufipennis. Red-winged Hylurgus. 



H. (rufipennis) niger, pUosus, subnitidus ; prothorace subcarinato ; elytris rvfis, sulcatis, sulcis punctatis, interstitiis dorsalibus 



scabris. 

 Red-winged Hylurgus, black, hairy, rather glossy ; prothorax with an obsolete ridge ; elytra rufous, furrowed, furrows 



punctured, with the dorsal interstices rough. 



Length of the body 3 lines. 



Many specimens taken in the Journey from New York to Cumberland-house, and 

 in Lat. 65°. 



DESCRIPTION. 



Body dusky, hairy, rather glossy, punctured. Head black, confluently punctured ; vertex obso- 

 letely channelled ; antennas rufous : prothorax constricted anteriorly, and dusky-rufous ; base with a 

 double slight sinus, and dorsal ridge terminating in an impression at the angle between the sinuses : 

 elytra rufous, furrowed; furrows punctured; interstices of the furrows rough with minute elevations, 

 especially at the base, which is inflexed : tibia? and tarsi dull-rufous ; the former denticulated on 

 one side. 



N. B. In some specimens the elytra and anterior part of the prothorax are piceous or nearly 

 black ; in others the elytra are testaceous, and the prothorax piceous and paler anteriorly. 



From Hylurgus the transit to the Rhynchophorous beetles by the lignivorous 

 genera Cossonus, &c. is very obvious, and has been admitted by Latreille and several 

 modern Entomologists. In the present arrangement, indeed, I have reversed that 

 of Latreille, because, for the reasons above stated, the passage is from one branch 

 of the Rectocera of Mac Leay by the Xylophaga to the Rkynchophora, which 

 keeps together the great body of lignivorous Coleoptera.
