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

 appropriately stricken from our lists. 



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

 constitute a genus perhaps allied to that including the Mexican 

 dromedarius, but the comparatively simple prothorax, impressed 

 inflated elytra and glabrous integuments form a singular combina- 

 tion, which prevents us from assigning it an}- definite position. 



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

 retained in Anthicus, and which is likewise undeterminable in its 

 affinities. 



A. pallidus Say, remains unknown. 



A. jiolitus Sa}', is more probably a xylophilide than an Anthi- 

 cus, but is completely indeterminate and ma}' be a Tachys or 

 some chrysomelide. 



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

 and differs completely in type from anything 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. t7'oglodijtes Boh., likewise differs altogether in type from an}'^ 

 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- 

 pletely in type, as in the two preceding cases, and is evidently 

 not North American ; it should also be omitted. 



A. nitidus Boh., seems to be allied to nitidulus Lee, but can- 

 not be identified with any of our species, than which it is much 

 smaller (1. 2^ mm.; w. | mm.); San Francisco. A. atomarius 

 Boh., does not appear to difl^er from nitidus ( 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 identitj^ can 

 be determined. 



Mr. Champion very kindly sent me, some years ago, a number 

 of tj'pical 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. asphallinits, jmnctipennis and occidenfalis Chinp., are members of the 

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

 peculiarities in occipital structure. 



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