AMERICAN COLEOPTERA. 01 



Lytta refulgens, n.sp. — Brilliant metallic green, thorax reddish yellow with 

 discuidal rounded metallic spot. Head shining metallic green with frontal yel- 

 lowish spot ; coarsely but densely punctured. Thorax regularly rounded on 

 tiie sides, slightly broader than long, feebly convex and with few scattered 

 punctures, disc with round metallic spot; narrow basal margin black. Elytra 

 brilliant green, scabrous. Under surface more shining. Femora metallic 

 green, tibice and tarsi black. Length .38 — .40 inch; 9.5 — 10 mm, 



Beloiips to the same group with stncipennis, Lee, which has how- 

 ever a wider thorax, and rufous vertex. The elytra are dark olive 

 green, and the under surface blackish green. The brilliant colors 

 will enable the present species to be recognised at a glance. 



Specimens from Millerton, California, collected by Mr. Wm. M. 

 Gabh. 



Lytta auriculatj, n. sp. — Body black, eh'tra greenish or bluish black. Head 

 with each liiiid angle and frontal spot red. Form slender, head black, coarsely 

 ])unetured, more densely ou the front. Thorax black, rather shining, coarselj' 

 punctured, sub-pentagonal, sides narrowed in front, sub-iJarallel or slightly 

 convergent behind the middle. Elytra one half broader than the thorax, 

 bluish or greenish black, scabrous. Beneath black, shining, coarsely butvery 

 Sjiarsely punctured, and with slight pubescence. Length .35 — .46 inch; 9 — 

 1 1.5 mm. 



IJelongs with aeneipennis and sniaragduhi^diiSarm^ by its more 

 elongate from sub-pentagonal thorax and color. The antennae are long, 

 nearly two thirds the length of body. 



Several specimens from Kern River region of California; found on 

 a small species of Lupin in flower. 



Lytta compressicornis, n. sp. — Brilliant blue sometimes slightly violet. 

 Head entirely blue, very coarsely but sparsely punctured. Thorax narrower 

 than the head, sub-quadrate, feebly narrowed at base, moderately convex, vvrth 

 few coarse irregularly j^laced punctures. Elytra twice as wide as thorax, finely 

 scabrous, gradually wider toward apex. Body beneath blue, shining, S)»arsely 

 jiunetured. Legs, mouth and anttnnte black. Anteunse with joints 5 — 11 

 i^trongly compressed in both sexes, broader in the male. Length .30 — .50 inch ; 

 s — 12 mm. 



In both sexes the spurs of the hind tibia) are slender and acute, 

 the inner longer. The tibiae are straight. This species differs how- 

 ever from any previously described, at least in our fauna, in having 

 the antenna; very strongly compressed. The joints from 5 to 11 are 

 transverso, unu-e than twice broader thin long. The antennae are 

 short, not longer than head, ami thorax. The male hus the last ab lo- 

 minal segment more deepl3' and acutely emarginate than is usual in 

 the species allied most nearly in general appearance, e.g. co/iwcxo, Lee. 



From Owen's Valley, California, collected on a plant resembling our 

 Canada thistle but with yellow flowers.
