150- HICKORY. TEUNK TIGER CERAMBYX. THE BEETL^v 



The head is retractile witliin and but half as broad as the second segment, and is ceaJ 

 Wack except' at its base, the black being edged posteriorly with chesnut brown. The- 

 upper lip or labrum is transverse oval, rather broader towards its base, honey yellow, 

 and covered with short yellow hairs which incline forwards. The upper jaws or mandr- 

 blesare robust, with an angular obtuse tooth-like projection near the middle of their 

 inner sides, their tips being simple and rather blunt. The antennse are minute conical 

 two-jointed points projecting outwards at the base of the mandibles and distant from^ 

 the base of the head. The feelers are thrice the size of the antennse, conical, three- 

 jointed apd of a chesnut brown color; the lobe of the lower jaws or maxillae projects 

 at the inner base of the feelers and is more than half their length and clothed with 

 short dense pubescence. The feelers of the lower lip or the labial palpi are minute but 

 perceptible. The throat is whitish, the suture at the base of the oral organs black 

 edged posteriorly with chesnut brown. The apical segment of the body is divided 

 into two parts by a transverse impressed line, and might, as in many other larvae, be 

 counted as two segments, the last on& being much more narrow and abort in this 

 insect. 



Th(e celebrated Swedish entomologist, Baron De Geer, long ago 

 published a description and figure of this beetle in the fifth volume 

 of his Memoires on Insects, page 11 3, under the name of Ceramlyx 

 tigrinus, or the Tiger Cerambyx, a name suggested perhaps from 

 its size and colors. It has lately been described by Rev. D. 

 Ziegler, and by Prof. Haldeman, under the name of Monohammus 

 tementosus, or the Wooly Cerambyx, which name, however, must 

 give place to that which was previously bestowed. Some of the 

 descriptions that have been published have evidently been drawn 

 from imperfect specimens, denuded of their pubescence in places. 



The medium length of this beetle is about one inch, though, like most other Long 

 horned beetles the two sexes differ much in size, the males being often only 0:85 

 whilst the females are 1.15. The ground color is brown, sometimes tinged with red- 

 di* or on the elytra with pale yellow; and the surface is covered beneath and for 

 the most part above with fine short appressed hairs of an ashy or a tawny-yellowish 

 white color. The head is punctured, at least on its summit, and has an impressed 

 line in its middle. The mouth is of a honey-yellow color above and beneath the 

 upper lip being hairy and blackish except at its anterior edge, and the mandibles are 

 deep blaok, their bases brown. In the notch of the eyes is an elevation on which the 

 antenna; are inserted. These are rather shorter than the body, eleven. jointed the 

 second joint very short and more broad than long; the basal joint is double the thick- 

 nes3 and but half the Icngtli of the third joint, which, with those that succeed it are 

 about equal in length and gradually diminish in thickness, Tlie two basal joints are 

 brown, all the others whitish or pale yellow and stained with brown at their tips. 

 The thorax is everywhere covered with short appressed hairs, which are more dense 

 beneath, and has on each side in the middle, a conical erect spine rounded at its apex. 

 The scutel is brown, its apical half covered with whitish or light yellow, hairs. The
