rowing rapidly through the wood. On a still day, in the 

 vicinity of logs infested by these grubs, one can hear at a 

 considerable distance the noise they make in driving their 

 tunnels. J/, scutellatus Say, a smaller black species, is also 

 very common and destructive. Goes pulverulcnta Hald. is a fine 

 brownish beetle, with sparse whitish pubescence, of which I have 

 beaten a few specimens from hickory. G. occiilata Lee. is much 

 smaller and has a black spot on each elytron. 



Tribe VII, Acanthoderini, offers seven genera with fifteen 

 species, principally small insects of rather flattened appearance 

 and with long slender antennae. Their general colour is greyish, 

 varied with markings or tufts of white or dark pubescence. 

 None of the species are so conspicuous as to attract attention 

 from non-entomologists. 



Tribe IX, Pogonochcri, is represented by three genera with 

 six species which are also all rather small and inconspicuous, 

 though showing somewhat more variety in their colour and 

 decoration. 



Tribe XIV, Saperdini, has only one genus, but this contains 

 ten species, including some of our most important longicorns. 

 Saperda calcarata Say, fully an inch long and prettily mottled with 

 yellowish pubescence, is known as the Poplar-borer. 5. Candida 

 Fab., with two bold longitudinal white stripes, is the Apple-borer 

 so destructive in some parts of America, but which here occurs 

 usually on Hav/thorn or Shadbush, and, curious to say, seems 

 confined to the Quebec side of the river. 5. vestita Say, clothed 

 with dense yellowish pubescence and usually with six small 

 black dots on elytra, is the common Basswood-borer. One of 

 the prettiest species is S. puncticollis Say, in livery of black and 

 yellow, with four conspicuous black spots on the yellow thorax. 

 This species bores in the stems of Virginia Creeper, and last 

 season Mr. Fletcher obtained numerous specimens and found 

 that the beetles, after emerging from the stems, fed upon the 

 leaves, which they riddled with holes. 



Tribe XV, Phytoeciini, concludes our series with tv/o genera. 

 Oberea bimaculata 01iv.,an elongate cylindrical beetle, black with
