LEPTURA. 83 



oi" subangulate at the middle of each side ; the basal angles pro- 

 jecting. El^^tra nearly parallel-sided, slightly narrowed posteriorly, 

 each oblit]uely truncate at the apex. Body beneath and legs 

 sparsely clothed with tawny pubescence. Pirst joint of the middle 

 tarsus as long as the remaining joints united, that of the hind 

 tarsus longer.

77. Leptura lavinia, sp. n. 



Sparsely pubescent ; black, the elytra sometimes reddish brown, 

 each of these marked in the female with seven testaceous- 

 yellow spots — two close to the base, one dorsal aiid the other 

 lateral, two at one-third from the base and united together to 

 form an obliquely transverse fascia constricted in the middle, two, 

 similarly united, placed just behind the middle, the seventh spot 

 placed near the suture between these and the apex but a little 

 nearer to the apex than to the spot in front ; these yellow spots, 

 •of which but one or two and traces only of the others are shown 

 in the single male specimen seen by me, are covered rather faintly 

 with fulvous pubescence. Head densely and finely punctulate, 

 cheeks and clypeus moderately long, the latter with a trans- 

 verse sulcate impression, above which a short triangular area, 

 less densely punctulate and more or less nitid, is marked off by 

 two obliquely converging sutural lines. Antennae of d" almost as 

 long as the body, those of 5 scarcely extend past the middle of 

 the elytra ; the joints cylindrical, increasing very slightly in thick- 

 ness from the fourth to the last, the third slightly longer than the 

 fourth and much shorter than the fifth. Prothorax about equal 

 in length to its width at the base ; constricted and marked with 

 a subsinuately transverse groove near the apex ; slightly protu- 

 berant on each side behind the anterior constriction, then widened 

 towards the base, which has a laterally projecting and acute angle 

 on each side ; the basal groove transverse towards the sides and 

 arched forwards in the middle ; the disc uneven, with a median 

 sulcate and two lateral broader depressions with raised spaces 

 between, the surface very densely and rather finely punctured. 

 Elytra broader at base than the base of the prothorax, nar- 

 rowed gradually and slightly until near the apex and then more 

 strongly ; truncate a little obliquely at the apex ; the surface 

 densely and very finely punctulate. First joint of the hind tarsus 

 a little shorter than the other joints united ; the cleft of the third 

 joint does not reach quite to the middle in the hind tarsi, but 

 reaches to the middle in the front and middle tarsi. Last ventral 

 segment of male subtruncate at the apex, faintly depressed in the 

 middle before the apex.
