The Orthosoma unicolor Drury (Fig. 477) is a hght bay col- 

 ored beetle found flying from the middle of July until Septem- 

 ber. We have found the larva (Fig. 478) in the rot- 

 ten stumps of the pine, and in the Western States 

 Riley states that a larva (Fig. 479, head and tho- 

 rax seen from beneath), probably of this species, 

 eats the roots of the grape-vine, hollowing out and 

 sometimes severing the root and killing the vine. 



Prionus brevicomis Fabr. is a very large, not un- 

 common beetle, of an ovate shape and pitchy black 

 color, with short, thick jaws, and 

 antennae about half as long as 

 the body. The larvte, Harris 

 states, are as thick as a man's 

 thumb, and are found in the 

 trunks and roots of the Balm of 

 Gilead and Lombardy poplar. ^'"- *"^- 



Grossidius pulchrior Bland (Fig. 480), 

 from Nebraska, is a pale reddish beetle, with the antennae, 

 head, base and the large mark on the disk of the clvtra and 

 legs black. An allied form is Eburia? Ulkei Bland 

 (Fig. 481, showing the sculpturing of the head) which is 

 described as coming from Cape St. Lucas, Lower Cali- 

 fornia. 



The larva of Stenocorus putator Peck (Fig. 482 ; a, 

 larva, just about transforming; 6, pupa) nearl}^ ampu- ^'^■'^^' 

 tates the branches of the black and white oaks. After becoming 

 mature in the trunk, and just before undergo- 

 ing its transformations, it gnaws off a branch 

 which falls to the ground, containing the larva, 

 which changes to a beetle in midsummer, and 

 Fig. 481. Jays its egg near the axilla of a leaf stalk or 



small stem. The beetle is a very slender one, with antennae 

 longer than the body in the males, the third and fourth joints 

 of which are tipped with a small spine or tliorn. It is dull 

 brown, with graj^ spots. The Banded hickory borer, Chion 

 (Cerasphorus) cinctus Drury, makes long galleries in the 



Fig. 479.
