XYLOTBECHUS. 249 



groove, but becomes single again, though much finer, on the 

 vertex. Antennae reach almost to the middle of the elytra in the 

 male; third to seventh joints setose posteriorly at the apex ; third 

 slightly shorter than the first, second a little longer than broad. 

 Prothorax longer than broad, rather feebly rounded at the sides, 

 widest in the middle, marked with an elongate median, and two 

 small, rounded, lateral black spots on the disc, with another small 

 black spot on each side. Scutellum pale yellow. Elytra a little 

 broader than the prothorax, narrowed very slightly behind, 

 dentate at 'the outer angles of the truncate apex ; the black 

 markings arranged on each as follows : (1) a short narrow band 

 extended back from the shoulder, curved inwards on to the disc 

 and then bent forwards ; (2) a narrow band which begins at or near 

 the suture at about one-third from the base, then runs back a 

 short distance, diverging at the same time from the suture, whence 

 it is curved sharply round so as to run obliquely forwards to the 

 side, where it again bends and passes straight out to the margin; 

 (3) a narrow band which begins at the suture a little behind the 

 middle, is directed obliquely forwards to the middle of the disc, 

 and then bent so as to run obliquely backwards to the side ; (4) 

 a band similar to the third and placed about midway between it 

 and the apex ; (5) a lateral spot a little before the apex. Hind 

 femora of the <S extend by about one-fourth of their length 

 past the apex of the elytra ; those of the only reach a little 

 past it.

282. Xylotrechus contortus, sp. n. 



This species has the structural characters of X. incurvatus, 

 Chevr., and a considerable resemblance to it in colour and 

 markings ; but the latter differ somewhat in form and position. 

 The first elytral band is reduced to two spots, one behind the 

 shoulder, the other on the disc ; the second band runs back nearly 

 twice as far as it does in X. incurvatus before it is curved round 

 and runs forwards ; the third band forms a much more regular 

 arcuate curve ; the fourth reaches neither to the suture nor to the 

 outer margin, sometimes reduced to a mere crescentic spot ; also 

 it is placed much nearer to the third band than to the apex. 



Length 12-15 ; breadth 3-4 mm.
