SPRUCE BORERS. 827 



vember, 1880. The track was made at the beginning of the roots, and 

 is slightly sinuous, 2 or 3 inches long ; 3""" wide, while the diameter of 

 the hole for the exit of the beetle is 2^ to 3°^" in diameter. 



6. Cujyes concolorWeatwood. 



Order CoLEOPTERA ; family Cupesid^. 



This beetle has been found by Mr. G. Sunt upon or among spruce 

 boards in a tannery in northern New York; hence he thinks it may be 

 a spruce insect. 



7. The pine longicorn borer. 



Monohammus confusor Kirby. 

 Order Coleoptera; family Cerambycid^. 



This common and pernicious borer has been described and figured on 

 pages 685-694. It occurred under the bark of dead spruces at Bruns- 

 wick, August 3 and 27. At the latter date three sets of the larvae 

 occurred — one measuring about 6"'°, another O^^™, and a third from 16 

 to 20°^™ in length. There were no fully grown worms. It is possible 

 that the eggs from which these came were laid in the early summer ; 

 but it is more likely that they were deposited by the female during the 

 previous summer, as the beetle is not to be seen except from June to 

 early September. 



8. The long-legged melanophila. 



Melanophila longipes. 



Order Coleoptera; family Buprestid^. 



This beetle is thought by Mr. George Hunt to bore into the wood of 

 the spruce, as he has found it on charred spruce timber under such cir- 

 cumstances as to lead him to believe that it depredates on this tree. 

 Nothing is known of the habits of the larva. 



The beetle. — Body deep black, immaculate ; thorax witli an ob- 

 solete indented line; sciitel small, subangulated ; elytra finely 

 granulated ; an obtuse, obsolete, elevated line from the shoulder 

 to the tip ; tip abruptly terminated by a small spine in the center ; 

 beneath polished, slightly tinged with violaceous. Tarsi of the 

 intermediate and posterior feet elongated, as long or longer than 

 the tibia ; first joint equal to tho three following ones conjointly ; 

 fourth joint bilobate, very short. Found in Pennsylvania and 

 the Western States. (Say.) 



Le Conte states that it inhabits Pennsylvania, 

 Kansas, and the Lake Superior region ; that it is very 

 closely related to the 'Em o])eau M. appe^idiculata, but fig. ■iso.-Meiano-

on comparison the thorax is less rounded on the sides, g^^j^j^ ^^^ 

 which are less sinuate posteriorly. As in that species, 

 the sculpture is very indistinct at the middle and the small carina at the 

 basal angles nearly parallel with the margin. The elytra are more grad-
