The species of Arimi-oih ni are not as elongate .as tliose of Ai\rilii^^

A large number of species of niedimu-si/.ed IJnprestiihe which are of a dark green, 

 coppery, oi' lilack-shining bronze coloi-, .and .are covereil with imjiressed dull spots, are 

 groniied ill the genus C/iri/sobofhris. ()f these sjiecies (.'._/(;•?»())•«<«, a greenish-black 

 species that varies from (1.4 to 11. (i of an inch in length, and two-thirds 

 .as wide, besiiles being, as l,ar\ a, injurious to oaks and other forest trees, 

 damages peach ,and pear trees, .and often causes serious f.at.alitv to apple 

 trees. These beetles are found from May until the laid of sunnner. 

 Tlieir pale yellow, thin->helled. ribbed eggs are Laid, sini:l\- or .a few, in 

 gr(ni|is, in (a-cvices of b.ai-k. The. young larva^, njion hatching, bore into 

 the liark .and li\(' liiaieatli it, in tl.itt(aied ch.annels, soon girdling sniall trees. Later, 

 as its jaws become .stronger, it attacks the solid wood, but always again comes to the 

 surface before pupation. After cutting a. ]iassage almost tlu-inigh the bark it retreats, 

 packs its (U'bris and e\-<a'emeut aliout it, and piijiates. Upon enua-eeiicc, the beetle, 

 which has feebler jaws than its larva, has no dithculty in reaching the open aii-. C. 

 luirrisli. one of the snndlest beetles of this genus, beine; onlv aliotit (l.o of an inch long, 

 is a sonu'wh.at r.are but livilliant species. Its larva lives in )iine twigs, and the brilliant 

 metallic-green licet le nniy lie fouml, iluring June and July in Xew England, s)iarklina" 

 in tlie hot sunlight mi the ti|is of white-]iine boughs; on account of its 

 sh^'ness and r.apid tJiLjiit it is not e.asilv c.i|itiired. 



Similar in foiaii to C/iri/snhotliris, hut h:i\ ing a broader front, is 

 Mdanopliiht. M. f(ih-,></i(tt<(t<i. of a brassy black color from 0.30 to 0.4ft 

 of an inch long, has three yellow dots upon each tdvtron. Tin's s|iecies 

 frequents pines throughout the northern I'liiti'd St.ates. 



In Biiprestis, a genus numbering, as at prestait limited, over Hftv 

 specie.s, many of «hich are beantifidly colored, the lieetles are ratlier larijer than in the 

 preceding gema'a. />'. rufpe.-i is a Xorth Ann-rican species, of which the earlier stao-es 

 .are unknown. />'. fdariiitu is one of the most brilliant species of this 

 genus. It is from D.tiO to D.T.'i of an in(di long, of a brilliant metallic- 

 green with golden reflections, with a snnill yellow spot near the tip of 

 each elytron, and a band of yellow nearly across each elvtron just in 

 front of the apical .s]iot. The larva probably feeds in willow or jiine 

 wood, and it inhabits the imrthern Fnited States. 



Dicerca iJlrarlcjifa, which is of a coppery-bronze cailor ami about 

 11.7ft of an inch long, is easily recognized by tlie prolono-ed and divero-ent 

 tips of its elytra; it is eoninion in the eastern United States. Its larva 

 attacks jieaeh, majile, cherry, and beecli trees.
