78 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Mr. George Hunt has found the beetle under the bark of au old 

 sugar maple tree in northern New York, among the Adiroudacks. 



Larva — Body of the usual shape, uear that of Phymatodes. Prothorax less than 

 one-half as long as wide ; disk exactly one-half as long as wide ; the disk is smooth 

 on the posterior half, irregular on the front edge, with abroad, irregular median lobe 

 in front; the front edge of this smooth space is often tinged with dark. In front of 

 this smooth area is a clear, pale, hairy space, and still beyond (anteriorly) are two 

 irregularly oval spaces which are hairy and irregularly spotted, and often tinted 

 dark. The under side of the prothoracic segment is quite hairy, with minute oval 

 patches among the hairs, and with two couspicuous small, dark, diverging patches 

 on the middle of the segment, but situated rather far apart. Mesothoracic segment a 

 little narrower than the prothoracic and shorter than the metathoracic segment, the 

 latter a little shorter and but very slightly wider than the mesothoracic segment. 



Body contracted on the sixth abdominal segment, which is considerably narrower 

 than the succeeding partof the abdomen, the seventh abdominal segment being wider 

 than the sixth and of the same width as the eighth ; the ninth much shorter and two- 

 thirds as wide as the eighth. The tenth segment small, one-half as wide, but nearly 

 as long as the ninth. Abdominal segments two to seven with transversely oval, 

 raised, smooth callosities, those on the sixth and seventh being round instead of 

 oval ; beneath are similar callosities. 



Head a little over one-half as wide as the prothoracic segment ; antennae three- 

 jointed ; second joiut one-half to two-thirds as long as the first and one-half as 

 thick. Third minute, about one-third as long as the second joint is thick. Maxilla 

 with the lobe as wide as the basal joint of the palpus and reaching to the end of the 

 second palpal joint; the maxilary palpi four-jointed, the second joint one-half as 

 wide as the first ; the third just two-thirds as wide as the second ; the fourth as long 

 but one-half as thick as the third. 



Labium with the ligula small and rounded, not more than one-third wider than 

 the basal joint of the labial palpus, the latter two-jointed, the second joint nearly as 

 long and about two-thirds as thick as the first. Mentum deeply cleft, one-half as 

 long as the submentum. 



Labrum small, rounded, not so long as round; surface convex, with dense hairs. 

 Mandibles obtuse, rounded, not toothed. 



Thoracic spiracles in the middle of the mesothoracic segment, with the usual eight 

 pairs of abdominal ones. Length of body, l?""'" ; width of prothoracic segment, 

 4.5"'"'; length, 2""" ; width of seventh abdominal segment, 3""". 



Pupa. — Prothorax well rounded, as in Clytus beetles ; anteunse slender, curving 

 backward and reaching to tne distal end of the middle femora. Femora much swol- 

 len, but the legs beyond slender, as in the beetle. (It will not be difficult to distiu* 

 guish the genus, from the peculiar form of the thorax, the swollen femora, and the 

 slender legs and antennjB.) Abdomen short, end of hind femora extending to the 

 third segment from the end of the abdomen. Length, 12 to 13^™"". 



The end of the body terminates in a pair of incurved hooks on each side, the inner 

 pair a little smaller than the outer. Six large recurved spines on the penultimate 

 abdominal segment, the other abdominal segment with about two irregular rows of 

 minute stout spines adapted for progression. 



Beetle. — Body rather long and narrow, not so broad and thick, nor the prothorax 

 80 spherical as in A', undulatus; prothorax with the sides regularly arcuate, two ashen 

 spots on each side in front and behind, and a curvilinear spot just behind the middle. 

 Wing-covers with three broad, irregular, waved pale bands, the first a little in front 

 of the middle, the second much behind the middle, and the third situated on the 

 tips. AutenuiB and legs dark-brown ; reddish-pitchy in immature specimens. A 

 large, round yellow spot on the side between the middle and hind legs, succeeded by 

 vertical linear spots on the hinder edge of the abdominal seirments. Length, 8 ta 

 16™™.
