NORTH AMKRICAN COLEOPTERA. 117 



This species is the only one in our fauna entirely blue above with 

 black legs. It resembles very greatly Scelida graptoderoides, but 

 may be known by the presence of spurs on all the tibiae. 



Occurs in California, Punto de los Reyes. 



L,. luorulus Lee, Proc. Acad. 1865, p. 210.— Oblong-oval, black, shining. 

 AnteniifB a little longer than half the body, second joint a little longer than half 

 the third, these two longer than the fourth. Head smooth, the transverse im- 

 pression straight, entire. Thorax one-half wider than long, sides feebly arcuate, 

 hind angles not prominent, disc moderately convex, a vague depression each 

 side, sparsely finely punctate near the front angles. Elytra one-half longer than 

 wide, sparsely and very finely punctate ; prosternum very narrowly prolonged 

 between the coxse. Body beneath black, shining. Length .14 inch. ; 3.5 mm. 



Male.— 'Lust ventral truncate at middle with a linear incisure, each side ex- 

 tending half the length of the segment. 



The hind legs are unfortunately wanting in my specimen. 

 The sexual characters of the last ventral of the male are precisely 

 those of thoradcus and varicornu. The length given by LeConte, 

 4 inch., is plainly a misprint. 

 Occurs in Texas, precise locality unknown. 



li. spretus n. sp.— Oblong-oval, black, shining, four basal joints of the an- 

 tenna; and the legs (except femora at base) yellow. Antennse three-fourths the 

 length of the body, second joint small, nodiform, scarcely half the third, these 

 two as long as the fourth. Head smooth, transverse impression straight, entire. 

 Thorax one-third wider than long, widest in front of middle, sides feebly arcu- 

 ate, hind angles not prominent, disc convex, smooth, a few very fine punctures 

 near the front angles. Elytra shining, sparsely finely punctate ; prosternum 

 narrowly prolonged between the coxie. Legs entirely yellow, except the bases 

 of the femora. Length .16 inch. ; 4 mm. 

 The male is unknown. 



The first joint of the hind tarsus is one-third the length of the 

 tibia, and scarcely as long as the following joints together. 



This species greatly resembles texanus in form, but differs in being 

 totally black above, and by the elytra much less distinctly punctate. 

 It also resembles the European Luperus niger, but differs in having 

 terminal spurs to all the tibiae and the anterior coxae distinctly sepa. 

 rated by the prosternum. 



Occurs in Texas, precise region unknown. 



Ij. niorrisoui Jacoby, Biol. Cent.-Amer. vi, pt. 1, p. 595.— Obloug, beneath 

 piceous, above metallic-blue or green. Antennae two-thirds the length of body, 

 piceous externally, the four or five basal joints pale, joints 2-3 oblong, nearly 

 equal in length, the two longer than the fourth. Head smooth, the transverse 

 impression deflexed at middle, entire. Thorax one-third wider than long, widest 

 in front of middle, sides anteriorly arcuate, thence slightly oblique to base, hind
