gard it also as Mexican ; these two species might therefore be 

 appropriately stricken from our lists. 



A. impressijyennis Laf., is evidently not an Anthicus, but will 

 constitute a genus perhaps allied to that including the Mexican 

 dr-omedarius, but the comparatively simple prothorax, impressed 

 inflated elytra and glabrous integuments form a singular combina- 

 tion, which prevents us from assigning it an}' deiinite position. 



A. exilis Laf., is another very peculiar species, which cannot be 

 retained in Anthicus, and Avhich is likewise undeterminable in its 

 aflSnities. 



A. jMllidus Say, remains unknown. 



A. jjolitus Say, is more probabl}' a xylophilide than an Anthi- 

 cus, but is completely indeterminate and may be a Tachys or 

 some chrysomelide. 



A. csesiosignatas Boh., is said to be from " Puna "Island, Cal., 

 and difters completel,y in type from an^^thing known in the United 

 States. Puna Island is off the coast of Ecuador, and it would 

 be perfectly safe to omit this species from our catalogues in the 

 future. 



A. troglodytes Boh., likewise differs altogether in tj'pe from any 

 known North American species and should be omitted ; it is said 

 to occur at San Francisco and in " Taiti." 



A. amplicollis Boh., said to occur at San Francisco, differs com- 

 pletel}^ in type, as in the two preceding cases, and is evidently 

 not North American ; it should also be omitted. 



A. nitidas Boh., seems to be allied to nitididus Lee, but can- 

 not l)e identified with any of our species, than which it is much 

 smaller (1. 'i^ mm.; w. f mm.); San Francisco. A. atomarius 

 Boh., does not appear to differ from nifidus ( 1. 2.0 mm.; w. f mm.); 

 San Francisco. As these two species have a North American 

 habitus, they might be retained in the lists until their identity can 

 be determined. 



Mr. Champion very kindly sent me, some 3'ears ago, a number 

 of typical representatives of species described or quoted by him 

 in the Biologia Centrali-Americana, and upon these it seems de- 

 sirable to remark as follows : — 



A. aspJi(iHini(><, 2ii>>icfip''>t»i>< find occidcntaliH Chmp., iire members of the 

 genus Lappus, but constitute one or two distinct groups, because of marked 

 peculiarities in occipital structure. 



A. teapensifi Chmp., belongs to the genus Sapintus, and has the character-
