AMERICAN COLEOPTERA. !):") 



41. M. ru Keeps Lee. Pr. Ac. Nat. Sc. Phila. xiv, 50. 



An indistinctly marked species which varies somewhat in size and 

 somewhat in color, being sometimes more rufous. It is not common, 

 but I find some specimens each season around New York. 



42. M. nubila Lee. Pr. Ae. 1858, p. 76. 



Of this I have seen only a single specimen ; it is close to ferruginoides, 

 but is darker than that species, and has in addition the rudimentary ridges 

 on tibia and tarsi of which there exists not a trace in ferruginoides. 



43. if I. splemleus sp. nov. 



PI. Ill, fig. 5, shows the combination of tarsal ridges peculiar to this 

 species. It is unique in this respect, and unique in the beautiful silvery 

 pubescence with which it is clothed ; it is very slender, and has the legs 

 unusually long and thin. On the specimen from Florida I observe 

 a rudiment of a third short ridge. Two specimens only, Illinois and 

 Florida ; Coll. of Dr. LeConte and myself. 



44. M. Ploridensis sp. nov. 



Closely related to the preceding, but distinct from it by the number 

 of ridges on the second tarsal joint, the deeper color, the dark pubes- 

 cence, stouter build and much shorter and stouter anal style ; the ridges 

 also are strongly marked and very distinct. 



45. UI. pustulata Mels. Pr. Ac. Nat. Sc. Phila. ii, 314, (Mordella). (PI. Ill, 

 fig. 7). 



Combination of tibial and tarsal ridges peculiar to this and the five 

 following species, PI. Ill, fig. 6. Distinguishable at sight from its allies 

 by the silvery pubescent spots with which it is adorned. Dr. LeConte 

 remarks that on one specimen he observed a rudiment of a fourth 

 ridge. I have been unable to find anything of the kind on the 

 species which I have examined, so that his specimen is probably aber- 

 rant in this respect. 



46. M. COHVicta Lee. Pr. Ac. Nat. Sc. Phila. xiv, 50. (PI. Ill, fig. 8). 



I have seen Dr. LeConte's type and drawn my figure from it. The 

 species seems closely related to the preceding but is rather heavier, and 

 differs in the markings. 



47. M. fuscipeuilis Mels. Pr. Ac. Nat. Sc. Phil, ii, 314, (Mordella). (PI. Ill, 

 fig. 9). 



Found occasionally around N. Y., and presenting no notable variations. 



48. M. pectoralis Lee. Agassiz L. Sup. p. 231, (Mordella). (PI. Ill, fig. 10). 

 I have seen one specimen only, and that the type. It is almost 



identical in all respects with ornata except that it has three instead 

 of two tibial ridges.
