EEVISION OF ELEODIINI BLAISDELL. 433 



The mesofeniora are gradually and .slightly thickened externally; 

 the grooves are structurally similar to those of the profemora, but 

 the edges become contiguous a short distance from the femoral base. 



The metafemora are but slightly narrowed at base, and therefore 

 have the opposed surfaces subparallel ; the grooves are as on the other 

 femora, but have the edges evanescent near the basal fourth before 

 becoming contiguous. 



The protibia? are obsoletely carinate externally and the tarsal 

 grooves more or less obsolete. 



The mesotibi* are subcylindrical and very slightly increasing in 

 diameter from base to apex; the grooves are faintly indicated and 

 the surface asperate. 



The nietatibia' are subcylindrical, narrowing slightly toward base; 

 the grooves are feeble and exist as narrow linear impressions between 

 the marginal asperities. 



The articular cavities of all the tibia? are quite closed. 



The tarsi are moderate in length and rather stout. 



The protarsi are about two-sevenths of their length shorter than a 

 mesotarsus. Joints 2, 3, and 4 subequal in length and just slightly 

 wider than long; the first is about one-half longer than the second; 

 the fifth about equal in length to the third and fourth taker together. 



The mesotarsi are a little shorter than a metatarsus. Joints 2, 3, 

 and 4 subequal in length and slightly decreasing in width in the order 

 named, together subequal to the length of the fifth ; the first about 

 one-half longer than Avide and a little shorter than the second and 

 third taken together. 



A metatarsus is at least half as long as its tibia. Joints 2 and 3 

 are about equal in length and breadth, together quite equal to the 

 length of the first or fourth. 



Note. — I sent to Mr. Blanchard an example of the peninsular form, 

 which I refer to insularis for comparison with innocens, with the fol- 

 lowing result: "It is surely a smooth innocensU The types are 

 1 male, 1 female, Arizona- having the elytra subsulcate, anterior 

 femora of the male angulate at outer three- fourths. In both sexes 

 the same femora markedly flattened and strongly marc/ined beneath." 



I had labeled the specimen E. insularis Linell, and Mr. Blanchard 

 still further writes: " I have been looking at the descriptions of in- 

 itoceits and insularis. It seems that the former was described from 

 Cape St. Lucas, but only specimens now in the collection are from 

 Arizona. The male does not have the large dense brush of golden 

 hairs on the first joint of the front tarsi as is said of insularisy 



Doctors LeConte and Horn both give Cape St. Lucas as the .type- 

 locality for innocens. The specimens which I consider as true repre- 

 sentatives of the sjiecies are quite like the peninsular form of insu-
