CERAMBYCID^: 273 



tennae not black but dark brown, of similar structure but rather 

 longer, fully as long as the body (cf) and more even in thickness 

 throughout, compressed, the last joint longer, much exceeding the 

 tenth; prothorax larger and more transverse, similar though less 

 strongly angulate at the sides, coarsely and densely but not so 

 continently punctate, the lateral callous spots broadly united 

 longitudinally and also transversely at base with the median callus, 

 which is prolonged anteriorly; scutellum much broader and very 

 much more obtuse, wider than long; elytra very much wider than 

 the prothorax, less than twice as long as wide (cf ) or a little more 

 than twice (9), similar otherwise, though more narrowed at tip 

 and with the central spot more elongate-oval, oblique and incon- 

 stant; legs (cf) rather long, with the thighs notably thicker than 

 in the shorter legs of the female. Length (cf,9) 10.5-15.0 mm.; 

 width 3.5-4.8 mm.; length of hind tibia (cf) 3-8 mm. California. 



ampla n. sp. 



A Similar but very much narrower, with the legs (c?) shorter and 

 pale throughout and with the femora less inflated; antennae 

 similar but more slender throughout, the second joint a little 

 longer, as long as wide, almost half as long as the third and not a 

 third as long as in the preceding, paler in color throughout. 

 Length 9.3 mm.; width 2.6 mm.; length of hind tibia (cf) 3.0 mm. 



California angusta n. subsp. 



3 Body rather broad in form, strongly shining, deep black, the testa- 

 ceous fasciae of the elytra near basal fourth and just behind the 

 middle; head better developed than in lignea, nearly as in ampla 

 but more densely and confluently punctate; antennae (cf) fully 

 as long as the body, notably and gradually stout basally, black, 

 the second joint longer than wide, almost one-half as long as the 

 third, fourth equal to the third and a little shorter than the fifth, 

 five to eight decreasing almost imperceptibly in length but rather 

 rapidly in thickness, the last very slender, longer than the tenth, 

 or ( 9 ) two-thirds as long as the body, more slender and equal 

 throughout, the eighth joint fully three-fourths as long as the 

 seventh; prothorax differing from the preceding forms in being more 

 narrowed basally than apically, less prominent medially at the sides, 

 otherwise nearly similar; scutellum obtuse, as wide as long; elytra 

 narrowed from base to apex, barely so in the female, coarsely and 

 loosely punctate throughout and more than twice as long as wide 

 in both sexes, the fasciae interrupted at the suture; legs black, the 

 thighs not larger in the male than in the female. Length (cf,9) 

 9.0-12.0 mm.; width 2.8-4.0 mm. California. [Hylotrupes liti- 



giosus Csy., Ann. N. Y. Acad., VI, p. 25] litigiosa Csy. 



Body broad as in the preceding but parallel, the elytra not narrowed 

 from base to apex, black, still more shining and with the bristling 

 hairs longer and more conspicuous anteriorly and on the antennae; 

 pale fasciae in nearly the same position but broader and not inter- 

 rupted at the suture, the anterior not straight but crescentic, the 

 attenuated ends flexed forward as far as the base in a fine line just
