158 MEMOIRS ON THE COLEOPTERA 



anteriorly; elytra not at all deeply, rugosely punctate. Length 9.5 

 mm. Lower California (Cape San Lucas). [Cyclocephala longula 



Lee.] longula Lee. 



Form elongate, testaceous, shining; head sparsely, more finely punctate, 

 black; clypeus parabolic, truncate, the apical margin strongly re- 

 flexed; prothorax sparsely punctate, the apical margin blackish, 

 somewhat narrowed anteriorly; elytra not at all deeply punctate. 

 Length 10.0 mm. Mississippi (Ship Island). [Cyclocephala sedi- 

 tiosa Lee.] seditiosa Lee. 



Besides the larger species described above, such as obesula, 

 oblongula and prona, I have at hand a series of eleven males and 

 one female, which, as a whole, are more slender and slightly smaller, 

 varying from 10 to 13 mm. in length. They were collected at 

 various points in southern California and are typical of the form 

 universally labeled longula Lee., in our collections. I have strong 

 reason to believe, however, that they are not longula, and they 

 appear to be somewhat composite, but to work out the various 

 closely related forms would be a vast labor in itself and require 

 large series from definite localities. The fauna of the region about 

 Cape San Lucas differs appreciably from that of the coast regions of 

 southern California, but tends to extend to the northward along 

 the eastern side of the peninsula as far at least as the upper end of 

 the gulf. I have simply translated the original descriptions of 

 longula and seditiosa and attach them to the table, further useful 

 taxonomy being impossible at present. Seditiosa would seem to 

 belong truly to this Section B of Ochrosidia and, if this is so, greatly 

 extends the geographic range of this peculiar group of species to 

 the eastward. 



Mr. Bates does not describe the male antennae of his Cyclocephala 

 ovuhim, and my single example is a female. The form of the 

 anterior tarsal claws of the male shows that it cannot be associated 

 with dimidiata, as suggested by the author; its general facies is so 

 similar to that of Ochrosidia that, if the antennal club of the male 

 were in any way similarly constituted, I should not hesitate to 

 regard it as the type of a Section C of this subgenus; at any rate, it 

 belongs in this vicinity and, if not a section of Ochrosidia proper, is 

 probably a subgenus equivalent in value to the following:
