THE AMERICAN ENTOMOLOGIST. 



The habits of all our species will not be 

 discovered for many years to come, but as 

 a working basis to guide future observers, 

 we have thought it would be well to re- 

 capitulate in the columns of the American 

 Entomologist what is already known re- 

 garding the habits of this family in North 

 America. We will do this as briefly as 

 possible, arranging the species in the order 

 of their more recent classification, merely 

 prefacing by the following explanations : 



Where the habit is well known and has 

 been repeatedly recorded and testified to 

 we simply give the first authority where 

 the facts are mentioned, quoting subse- 

 quent authorities only when a difference 

 in habit is noted. 



Unpublished observations are indicated 

 by the name of the observer only. 



The abbreviations are few and as 

 follows : 



Am. Ent. — American Entomologist. 



Am. Nat. — American Naturalist. 



Harris — A treatise on someof the insects injur- 

 ious to vegetation, by Thaddeus William Harris, 

 M. D., edited by C. L. Flint. 



Prac. Ent. — Practical Entomologist. 



Can. Ent. — Canadian Entomologist. 



We shall be pleased to publish any fur- 

 ther experience from the readers of the 

 Entomologist that will serve to complete 

 the summary here given, and we tender 

 our thanks to Drs. Le Conte and Horn, 

 Mr. Schwarz, Mr. Fuller, and others, for 

 notes and references that have helped to 

 complete the list. 



Ergates spiculatus (Lee), bores in Piitus pondeivsa 

 in Colorado, (A. S. Fuller). 



Mallodon dasystoinus (Say), boring in Live Oak, 

 Hackberry, Pecan, attacking trees in healthy 

 condition and often greatly injuring them, 

 but preferring trees which have already suf- 

 fered from one or another cause. The per- 

 fect insect issuing from April till August, 

 in Florida and Texas (E. A. Schwarz). 



Mallodon mclanopi/s (Linn.), breeds in the Box 

 Elder {Acer ncgui/di)) — E.G. Mumford, Bell 

 Co., Texas ; (auctore A. S. Fuller); boring 

 in the roots of oak shrubs at Cedar Keys, 

 Fla., the beetle appearing in June ; boring 

 in Cellis Texana near Columbus, Texas 

 (E. A. Schwarz). 



Mallodon serrulatus (Lee), boring in Celtistexatia, 

 Columbus, Texas, the perfect insect ap- 

 pearing in July (E. A. Schwarz). 



Orthosoma brunneutn (Forst.), "inhabits pine 

 trees" (Harris p. 96). " The larvre which I 

 suppose to be this species is common under 

 the bark of pine logs" (Fitch, 4th Rep., p. 28). 



Priomis laticoUis (Drury). The larvse live in the 

 trunks and roots of the Balm of Gilead, Lom- 

 bardy Poplar, and probably in those of other 

 kinds of poplar also (Harris, p. 96) ; in roots 

 of grape vine and apple trees, (C. V. Riley, 

 2nd Missouri Report, pp. 87-88); in decaying 

 oak stumps (C. V. Riley, I.e., p. 91). 



Friojius itnhiicornis (Linn.), larva infesting grape 

 roots ; feeding upon the roots of herbaceous 

 plants (C. V. Riley, 2nd Missouri Rep., p. 

 89-91); in roots of pear trees (C. V. Riley). 



Tragosoina Harrisii (Lee). Fitch infers that it 

 breeds in the Pine (8th Rep., p. 29) ; larva 

 in decaying stumps of pine trees near Mar- 

 quette, Mich., the perfect insect appearing 

 at the beginning of August (E. A. Schwarz). 



CERAMBYCID.IJ. 



AscDtum nioestum (Hald.), "found in all stages 

 under the bark of oaks early in May '' (Pack- 

 ard, p. 496) ; boring in grape vine according 

 to Dr. Shimer (Packard, ib.) ; bred from 

 Scotch Pine (C. V. Riley) ; pupa found 

 under bark of pine stumps near Tallahassee, 

 Fla., in March (E. A. Schwarz). 



Criocephalns nubilus (Lee), larva boring in roots 

 of Yellow Pine which had been laid open b}' 

 a newly made ditch, Tampa, Fla. ; the per- 

 fect insect appearing in April (E. A. 

 Schwarz). 



Smodicum cuctijiforme (Sav), larva boring under 

 dry bark of Live Oak (Fla.), Beech (Mich.), 

 and Hackberry (Texas) (E. A. Schwarz). 



Dularius brevilineus (Say), boring in dry elm 

 wood. " It lives in dry as well as dead elm, 

 but usually in such trees as are partly dead " 

 (Am. Ent., I, p. 228). 



Hylotrupcs bajuliis (Linn.), inhabits fir, spruce and 

 hemlock wood and lumber (Harris, p. 100) ; 

 " on dying Arbor-vitse in May in Washing- 

 ton, D. C. (C. V. Riley). 



Hylotrupes lign e7(s (Fdihr.), boring in sap wood of 

 Red Cedar, Manhattan, Kan. (C. V. Riley). 



Phymatodes variabilis (Linn.). "The larva of this 

 insect may be found in early Spring, 

 under the bark of White Oak logs and 

 stumps " (Horn. Proe Ent. Soe, Phil., I, 

 p. 30); boring in the hoops of powder bar- 

 rels (Am. Nat., 1879, p. 262). 



Phymatodes varius (Fabr.), is found with Calli- 

 diuiii variabile (Horn. Proe Ent. Soe, Phil., 

 I. P' 30); " is probabl}' an oak borer, speci- 

 mens having been found in the trunk of a 

 Black Oak " (Fitch 5th Rep., p. 13); "from 

 • oak wood in all probability" (C. V. Riley). 



Phymatodes amoenns (Say), boring in dead wood 

 of Isabella and Clinton grape vines (Shimer 

 Proe Am. Ent., Soe II, p. 9). 



Callidium antennatum (Newm.), larvtc mostly 

 j just under bark of pines. " Just before they 



are about to be transformed, they bore into 

 i the solid wood to the depth of several 



inches " (Harris, pp. loo-ioi) ; bores in pine 

 wood and in Red Cedar, mining under the 

 bark (Packard, Guide, p. 496); "the larva 

 living in the trunks of pines, excavating a 

 wavy shallow track under the bark, which is 

 packed full of sawdust, and when almost
