are usually piceous, the tarsi somewhat paler. The scutellum is 

 always black, even in the palest specimens, while the antenuie are 

 always pale, except the club, which is usually darker. The sides of 

 the thorax are not at all sinuate before the hind angles, which are 

 obtuse, though fairly well defined. The thoracic punctuation is 

 evidently finer and sparser than in backii. Length 6.2-7.5 mm. 



Hab. — California; Kaweah (4275-6000 feet), and "Tuolumne 

 County, Mokelumne Hill" (Blaisdell). Nevada. 



I have seen many specimens collected by Mr. Ralph Hopping at 

 the first named locality, and these are to be regarded as the types. 

 The Nevada specimens are slightly different in some minor respects, 

 but I have little doubt of their identity. 



11. D. nana sp. nov. 



Very small, black, elytra brilliant green, with pale lateral margin. Head 

 densely punctate, clypeus truncate, or even very faintly sinuate in front, the 

 margin rather strongly reflexed ; clypeal suture slightly impressed. Thorax 

 small, shining, rather coarsely but usually very sparsely and somewhat irregu- 

 larly punctate ; sides not sinuate posteriorly, hind angles very obtuse. Elytra 

 coarsely punctate, sutural angle subacuminate. Length 5i-6 mm. 



i/a6. —California ; San Diego (Dunn), Poway (Blaisdell). Eight 

 examples. 



This pretty little species is the smallest in our fauna, and all 

 specimens thus far known are from a very restricted locality. It is 

 most nearly related to miiscala, but appears to be distinct by its 

 uniformly more brilliant color, smaller size, less conspicuous pubes- 

 cence, more strongly reflexed clypeus, which is more squarely trun- 

 cate in front, with less broadly rounded angles, more sparsely and 

 relatively more closely punctured thorax, and by the form of the 

 sutural angle of the elytra. 



12. D. muscula sp. nov. 



Piceous, elytra bronzed, more rarely with greenish or faint cupreous lustre; 

 side margin narrowly pale. Head feebly but closely sculptured, clypeus faintly 

 arcuate in front, the angles broadly rounded, margin rather narrowly reflexed, 

 suture lightly impressed. Thorax strongly rounded at sides, which are not sinuate 

 posteriorly ; hind angles rounded, not defined ; surface finely somewhat sparsely 

 punctate, ba.se finely margined, subapical line distinctly impressed. Elytra 

 rather coarsely closely punctate; body throughout conspicuously pubescent. 

 Length 5i-8 mm. 



Hab. — California (Los Angeles County). Sixteen examples.
