NORTH AMERICAN COLEOPTERA. 279 



This species is readily known by its color and bright shining sur- 

 fiice, the antennae being of different colors at base, apex and middle, 

 and by the small fuscous cloud on the middle of each elytron. The 

 humeri is more prominent than in any other species in our fauna. 



Feeds on Heliophytum indicum, as I am informed by Mr. Schwa rz. 



Occurs at Selma, Alabama, and Columbus, Texas. 



2. Li. siibriiriis Lee— Oblong oval, couvex, rufotestaceous, moderately 

 shining. AntcTinre pale, outer five joints fuscous. Head smooth, shining. 

 Thorax one-third wider than long, not narrowed in front, sides arcuate, not dis- 

 tinctly oblique at the front angles, ba.sal marginal line extremely fine, disc mod- 

 erately convex, very sparsely and finely punctate and shining. Elytra wider 

 at base than the thorax, humeri obtusely rounded, umbone moderately prominent, 

 sutural angle obtuse % , or rounded 9 - *^l'sc convex, the punctures moderate, not 

 closely placed, smoother at sides and apex. Body beneath a little darker than 

 above. Abdomen sparsely punctate. Legs pale rufotestaceous, the posterior 

 femora a little darker. Length .10 — .12 inch. ; 2.5 — 3 mm. 



This is one of the larger and more conspicuous species in our 

 fauna. It resembles alternata, but in addition to the structui'e of the 

 antennje, the present species is much more finely punctured. 



The male has the last ventral segment sinuate each side, the me- 

 dian lobe moderately prominent and concave. The male is narrower 

 than the female and the thorax less transverse. 



Occurs in Kansas, collected in numbers by Prof F. H. Snow. 

 Lives on Onosmodmm, Dr. Sliimer. 



3. 1.1. turbatus n. sp.— Oblong oval, not very convex, piceous brown or 

 castaneous, shining, surface with extremely faint brouze lustre. Antennae witli 

 four basal joints pale, outer joints gradually piceous. Head smooth. Thorax 

 nearly one half wider than long, apparently slightly narrowed in front, sides 

 feebly arcuate, slightly obliquely truncate at anterior angles, base arcuate, mar- 

 ginal line wanting. Elytra wider at base than the thorax, humeri rounded, 

 umbone moderate, sutural angles well defined, disc moderately convex, the punc- 

 tuation rather coarse and close, smoother at apex, the punctures vaguely in series. 

 Body beneath as dark as above. Abdomen sparsely punctate. Anterior four 

 legs and posterior tibiae yellowish testaceous, posterior femora brown. Length 

 .10 inch. ; 2.5 mm. 



This species is more oblong and more coarsely punctate than ore- 

 f/onensls. It seems to be mixed in all collections with melanuriis, 

 but differs from that not only by the structure of the antennte, but 

 in the absence of the alutaceous surface seen in that species. 



Occurs at Galesburg, III. (Strumberg), and Detroit, Mich., Selma, 

 Ala., San Antonio, Texas (Schwarz).
