COLEOPTERA OF NEW MEXICO AND ARIZONA. j^i 



SUPPLEMENTARY NOTE. 



While the above catalogue is passing through the press, a copy of 

 the sixth part of "Coleopterological Notices," by Captain Thos. L. Casey,* 

 has come to hand. The family Anthicid^e is subjected, in its entirety, to 

 complete revision, and among other changes we note that the author advo- 

 cates the dismemberment of the old genus Atithicus, and the establishment 

 of a number of smaller genera at this expense. The characters upon 

 which this proceeding is based are found primarily in the form of the 

 mesosternuin, after which the shape of the prothorax, in combination with 

 antennal and palpal structure, is chiefly employed. As the result, several 

 of the species in our list are made members of his new genera; A. tenuis is 

 the type of Buiiliiis, A. obscurus is removed to Lappiis, A. caUfornicns to 

 Tkicanus, A. confinis to Vacnsiis, and A. fidvipes to Sapintus, the re-t remain- 

 ing in Anthicus, which, even as restricted by Captain Casey, is a genus of 

 great size. From our collections several species are described as new. 

 These are as follows: 



Lappus cur-Sor Casey. Peach Spring, Walnut. 

 L. SUBTILIS Casey. Gallup. 

 Thicanus mimus Casey. Coolidge. 

 Vacusus desertorum Casey. Holbrook. 

 V. PROMiNENS Casey. Peach Spring. 

 Anthicus parallelus Casey. Coolidge. 

 A. iNNocENs Casey. Peach Spring. 



Means are not now at hand for determining the facts with certainty, 

 but it seems probable that the name subtilis has been applied to the form 

 heretofore distributed as obscurus, while iiiiiocciis is likely that which is 

 recorded as nanus.
