slender, and the species are generally long, flattened beetles 

 of ver}' tough thick consistence, and are found on flowers, or 

 sunning themselves on the bark of trees in midsummer. Tlio 

 larvffi are flattened footless grubs, -vyith the 

 prothoracic ring greatl}' enlarged. 



In ChcdcojjJiora the antennal pores are dif- 

 fused on the sides of the joints, or only on 

 the lower margin ; the mesosternal 

 suture is indistinct ; the antennae arc 

 inserted in small fovea?, and the pos- 

 terior tarsi have the fii'st joint elon- 

 gated. C. Virginiensis Drury is one 

 of our most common species, and 

 ma}^ be seen flj'ing about pine trees 

 in hot daj'S in May and June. Its 

 larva bores into pines, often proving 

 very injurious. Fig. iVi. 



Dicerca is noted for having the tips of 

 the elj'tra lengthened out and diverging 

 from each other. Dicerca divaricata Say is 

 frequently met with ; it is smoother than 

 usual and highl}- polished with a 

 bronzed hue. The elytra are 

 marked with numerous fine irregu- 

 lar impressed lines and small ob- 

 long square elevated black spots. 

 The larvae attack the wild cherry 

 and the garden cherry and peach. 

 Dicerca lurida Fabr. is found on 

 the trunks and limbs of tlie 

 hiclvory. 

 The genus Chrysobothris differs in having the 

 antennte inserted at the inner extremity- of two short 

 oblique grooves, b}^ which the front is narrowed ; 

 the anterior femora are strongly toothed, the third *'°' *^'' 

 joint of the tarsi is truncate, while in the hind tarsi tlie first 

 joint is elongated. The species are rather broad and flattened, 

 witli impressed bands and spots on the elytra. Clirysohotliris
