from about 5/g to almost ^ inch in length. It is a lurid brassy color above 

 and a bright coppery underneath. The tips of the wing covers diverge 

 slightly and each bears a pair of small spines. 



The larva is a yellowish white color, long, narrow, depressed in form 

 and with abruptly widened thoracic segments. The head is brownish, small, 

 and largely concealed by the prothorax. The mandibles are tridentate, 

 black, the antennae very short. The prothorax is short and transverse, the 

 mesothorax is oval, broader than long, and much depressed or flattened ; 

 the following segments are much narrower, gradually becoming longer. 



Life history and habits. We bred this insect from hickory limbs June 

 10 and July i, and Dr Harris states that this species occurs during the 

 greater part of the summer on the trunks and limbs of hickories. The 

 larvae make shallow burrows in sickly and dying limbs. This species is 

 recorded from West Virginia by Dr Hopkins, who met with specimens 

 May 2. 



Distribution. This borer is common in the Middle, Southern and 

 Western States, according to Dr LeConte, and appears in a number of 

 local lists for the northeastern United States.

Calloides nobilis Say 



A stout, black beetle with golden yellow spots and transverse bars on its wing covers 

 occurs on chestnut, oak and hickory in midsummer. 



This rare insect is a magnificent beetle closely related to the very 

 destructive sugar maple borer, Plagionotus speciosus Say, which 

 it resembles in general structure. It probably has somewhat similar habits. 

 This very dark brown or black beetle may be instantly recognized by the 

 three bright yellow spots at the base of each wing cover, the smallest being 

 at the extreme margin, in connection with the two somewhat transverse 

 lines of the same color across the apical half. This attractive insect is 

 rare in our collections and is probably not very abundant, though its pre-
