1. L. thoracic us. Calomicrus thor. Mels., Pr. Acad. Nat. Sc. Phil. iii. 162. 

 Pennsylvania, Georgia, Kansas ; rare. Somewhat less elongated than the 



other species, and resembling in appearance Haltica collaris Fabr. The 

 second and third joints of the autennae united are longer than the fourth ; the 

 elytra are black, slightly bronzed, and strongly but finely punctured. The 

 thorax is transverse, of a pale yellow color. 



2. L. fibulatus. Galleruca Jib. Germ., Ins Nov. 601; IGall. 4-notata 

 Oliv., Ent. vi. 665 (No. 93, 89) ; pi. 5, f. 90. 



A specimen from Pennsylvania, given me by Dr. Melsheimer. It agrees 

 perfectly with the figure and description of Olivier above cited, but the local- 

 ity as given by him is Java. The type was contained in Bosc's collection, 

 which contained many United States species, and it is quite possible that the 

 locality became confused. 



Germar does not mention that the occiput is dark-colored; otherwise, his 

 description applies to the specimen before me. 



3. L. bivittatus. Phyllobrotica biv. Lee, Pr. Acad. Nat. Sc. Phil., 

 1859, 81. 



California ; first collected by Mr. Xantus at Fort Tejon. 



4. L. flavicollis. Phyllobrotica fiav. Lee, Pr. Acad. Nat. Sc. Phil., 

 1859, 81. 



Also found at Fort Tejon, Gal., by Mr. Xantus. The sexual characters are 

 as in the following species. 



5. L. smaragdinus Lee, Proo. Acad. Nat. Sc. Phil., 1859, 286. 

 Capes Reyes and Mendocino, California ; Mr. G Davidson. Differs from 



the next by the less densely punctulate thorax, and entirely black legs. 



6. L. varipes Lee, Report Pac. R. R. Expl., p. 69. 

 San Francisco, California ; not rare. 



7. L. cyanellus, elongatus, supra cyaneus nitidus, thorace lati- 

 tudine breviore, angulis anticis rotundatis, posticis rectis haud prominu- 

 lis, disco convexo punctulis paucis fere obsoletis versus latera impressis, 

 elytris parce fere obsolete punctulatis ; subtus niger, pedibus flavis, antennis 

 fuscis articulis 4 primis flavis. Long. *15 -20. 



Western States ; Michigan, Illinois. Differs from the two following by the 

 brighter color, and by the thorax being broader than its length, with the 

 hind angles not prominent. The antenna? and feet vary in color, the thighs 

 being sometimes marked with a black line ; and the antennae being sometimes 

 entirely yellow. 



8. L. rufipes Zee, Col. Kansas and New Mexico (Smithsonian Contr., ) 

 p. 27. 



Santa Fe, N. Mexico ; collected by Mr. Fendler. Of the same size and color 

 as L. m e r a c a, but differs by the elytra being obsoletely punctulate, and the 

 feet uniform yellow. The sides of the thorax are less rounded, the front 

 angles not at all prominent, and the hind ones not so dentiform. 



9. L. m e r a c a. Galleruca mer. Say, Journ. Acad. Nat. Sc. Phila., v. 299 ; 

 ed. Lee. ii. 344. 



Pennsylvania, Illinois, Kansas, Georgia ; not rare. The anterior angles of 

 the thorax are acute, the hind ones dentiform, the elytra finely punctulate, the 

 antennae uniformly yellow, and the feet yellow, with the thighs more or less 

 varied with piceous. 



10. L. longulus Lee, Report on Pacific R. R. Expl., p. 69. 



One specimen, Oregon. Narrower than the preceding species ; the thorax 

 is longer than wide, with the front angles not prominent, the hind angles 

 dentiform, and the disc finely and sparsely punctulate each side and at the 

 1865.]
