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Unpublished observations are indicated 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 bj' 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. 



PRIONID.E. 



Ergates spiculatits (Lee), bores in Pinus ponderosa 

 in Colorado, (A. S. Fuller). 



Malhnlon dasystonnis (Say), boring in Live Oak, 

 Hackbcrry, 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 melanopiis (Linn.), breeds in the Box 

 Y,\t>iftx {Acer negundd) — 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 Celtis Texana near Columbus, Texas 

 (E. A. Schwarz). 



ilallodon serrulalus (Lee), boring in Celtis texana, 

 Columbus, Texas, the perfect insect ap- 

 pearing in July (E. A. Schwarz). 



Orthosoma brunneum (Forst.), "inhabits pine 

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

 suppose to be this species is common under 

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



Piionus laticollis (Drury). The larva; 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-S8); in decaying 

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



Prionus imbricornis (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 (Sth Rep., p. 2g) ; larva 

 in decaying stumps of pine trees near Mar- 

 quette, Mich., the perfect insect appearing 

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



CERAMRYCID.E. 



Asciituin moestiim (Hald.), "found in all stages 

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

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

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

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

 under bark of pine stumps near Tallahassee, 

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



Criocephalus nubilits (Lee), larva boring in roots 

 of Yellow Pine which had been laid open by 

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

 fect insect appearing in April (E. A. 

 Schwarz). 



Snwdicum cuciijiformc (Say), larva boring under 

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

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



Dtilarius brcvilincus (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 bajttliis (Linn.), inhabits fir, spruce and 

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

 " on dying Arbor-vita; in May in Washing- 

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



Hyhtnipes ligne lis {Fa.hr. ). boring in sap wood of 

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



Phymntodis viii-iabilis (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., \,

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



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

 diicm 7'iinabi/t' {Horn. Proc. Ent. Soc, Phil., 

 1, p. 30); " is probably 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). 



Pkymatot/cs anioenus (Say), boring in dead wood 

 of Isabella and Clinton grape vines (Shimer 

 Proc. Am. Ent., Soc. II, p. 9). 



Callidium antcnnalum (Newm.), larva; mostly 

 just under bark of pines. " Just before they 

 are about to be transformed, they bore into 

 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. 49O) ; "the larva 

 living in the trunks of pines, excavating a 

 wavy shallow track under the bark, which is
