Subfamily MAGDALINIDES. 



Kostrum rather long and cylindrical; 

 scobes linear, commencing near the 

 middle, and reaching the base. Eyes 

 transverse, approximate above. Pro- 

 sternum not excavated. Small spe- 

 cies of an oblong parallel form, glab- 

 rous, usually black or blue, but 

 sometimes reddish. Thorax deeply 

 pa'fkarr'^™ ''''''^^""' '""^ '' P"^'^"""^"' puuctatc. Elytra punctate and stri- 

 ate. The larv» depredate upon the pine, boring into the pith of the 

 smaller branches. A foreign species is said to have been reared from 

 a larva found in burrows under the bark of willow trees. The M. armi- 

 collis, Say, inhabits the elm. Nearly all the species belong to the typical 

 genus 3£agdaUs, Germar, of which seven N. A. species have been de- 

 scribed.

Subfamily HTLOBITDES. 



Eostrum twice as long as the head, cylin- 

 drical, sometimes moderately robust ; 

 scrobes deep, linear and oblique. Scape

rather large. Body oblong and pubescent, after Packard. 

 The larvfB gnaw galaries under the bark of trees, chiefly the pines, 

 often doing much injury. This habit is expressed by the family name, 

 which means, living in wood. 



The sub-family contains the following N. A. genera : Hylohius, Ger- 

 mar, 3 species. JEudocimus, Sch., 1. Pissodes, Germ., 5. Heilipus, Germ., 

 3. Lepyrus, Germ., 3. 



Sub-family ERIRHINIDES. 



From the Greek ptv, ptvoq^ the nose or snout^ with the intensifying 

 prefix £/9£. Rostrum long and slender. Scrobes commencing at a 

 distance from the mouth and reaching the eyes. AutennsB long and 

 slender. Scape sub-clavate. Tibiae slender, not compressed, and usu- 

 ally with a spine or claw at the end. These are distinguished from 

 the Hylobiides chiefly by the form of the tibiae ; but they embrace a 

 number of groups, each of which has some remarkable peculiarity.
