form of a short roundish process at the inner hase of the feelers. The feeTers of t Je- 

 lower lip (labial palpi), are also perceptible, forming a eonical two-jointed process 

 of a chestnut color, inside of each lower jaw_ The antenrae are also represented by 

 a small, jointed, projecting point, near the outer angles of the head, so minnte that 

 we sViouM little suspect it would become developed into the long horn which we find 

 in. the winged beetle. Scattered over the remainder of the body, more densely in 

 particular places, are numerous short brown hairs. The second segcaent is larger 

 than any of the others, as shown in the following cut j its upper side slopes obliquely 

 downwards and forwards, and is occupied by a large smooth spot of a pale tawny 

 yellow color, the posterior part of which is covered with brown points; beneath is a 

 smaller transverse space, occupied by similar points, bitt with a band destitute of 

 them ranning across its-middle, and on each side is a pale tawny yellow spot desti- 

 tute of these brown points. The third and fourth segments are shorter than the 

 following ones. On the top of thefourth and each of the succeeding segments, to 

 to the tenth, is a transverse wart-like elevation, divided into two parts by a strongly 

 impressed loneitudinal line. Along each side the spiracles or 'breathiDg 

 pores form a row of nine chestnut brown dots, situated upon the second, the 

 fifth and each of the following segments ; and immediately below these is an 

 elevated longitudinal ridge, which is interrupted at the joints. Beneath, as 

 above, is a transverse wart-Vike hump on the middle of e&eh segment frono 

 the fourth to the .tenth, with a faint longitudinal impression across its 

 middle. There tire thirteen segments in all, separated from each other by 

 strong constrictions. The last one of these is double, or appears like two 

 segments, its posterior portion being but half as broad as the anterior, into> 

 which it is deeply sunk. 



The perfect insect or beetle measures from slightly over one-half to plump three- 

 fourths of an inch in lergth, and from 0. 17 to 0.25 in width, the males being smaller 

 and much more slender than the females. It is covered with dense appressed' 

 milk-white p bescence, and above arfe three broad stripes, formed by short appressed 

 hairs, of an umber orbutternut brown eolop, not a fuscous brown, as is stated in 

 some of the descriptions. These stripes commence upon the base of the head and 

 extend the whole length of the body. Both upon the thorax and the' elytra 

 they are coarsely punctured, each puncture yielding a short black nearly erect 

 bristle. The middle stripe embraces the suture of the elytra, is gradually nar- 

 rowed to a point posteriorly, and does not reach the apex of the suture. The outer 

 strfpes are narrower on the thorax, and occupy the outer half of each elytrum, 

 and are edged exteriorly at their tips with white. The white portions of the sur- 

 face are clothed with fine white hairs, which on the face are Interspersed with black 

 bristTes arfsing from fine black punctures. The head has an impressed black line in 

 its middle, upon whi«h in the center of the face is a brown spot, which is round 

 Eidney-shaped. or like the letter V. In the females this spot is sometimes wanting, 

 or is replaced by two faint dots. The mouth is black, with the labrum or upper lip 

 and the bases of the mandibles clothed with white Si;>pressed hairs. The eyes are 

 coal black. The antennse aie inserted upon a .short broad prominence which arises 

 fo the notch of the eyes. They are slightly longer than the body in the males, and 

 shorter in the female.s. They are composed of eleven joints, whereof the second 

 one is quite short and all the others long and cylindrical, the basal one beii^ taueh
