I should not at all hesitate, therefore, to consider the Californian A. P i c c o- 

 1 o m i n i i as distinct from Say's species, were it not for the preposterous collar 

 which, in Mr. Reiche's figure, is appended to the base of the thorax, and for the 

 very inaccurate representations given by his draughtsman of the two species of 

 Omus found in Oregon, (I. c. 7, pi. 10.) Such figures might be excusable in 

 America, where artists have not yet turned their attention to objects requiring 

 such accuracy of delineation, but in parts of Europe where accurate figures have 

 been made, and as the yearly accessions to our scientific libraries show can still 

 be made, such figures as those published in the Annales above quoted, of Am bly- 

 chila and Omus, are hardly to be commended. 



Having found near San Francisco, in California, some specimens of Omus 

 californicus Esch., I avail myself of the present occasion to remark, that 

 it is very closely allied to O. A u do u in i Reiche, and in fact only differs by 

 having the head and thorax very densely and deeply wrinkled, and the punctures 

 of the elytra more equal in size : the appearance of rows of punctures jiiven in 

 the very wretched figure accompanying Eschscholtz' description (Zool. Atl. tab. 

 4, fig. 1,) and copied by Reiche (1. c. sup ) is hardly apparent. 



The epipleurae in Omus are narrow, and defined by an acute line, which unites 

 with the margin near the apex of the elytra. In Amblychila the epipleurae are 

 broad, and the defining elevated line becomes obsolete about one-fifth from the 

 tip. The discoidal costa is about the same length : the intermediate costa (called 

 by Say the marginal elevated line) is more elevated, and extends to about one- 

 seventh from the tip : the smaller punctures of the elytra become effaced 

 towards the tip, and the large ones (each of which bears a small elevated point,) 

 are somewhat more numerous. 



The references to this genus are : to the New Mexican and Nebraska one, 

 Amblychila cylindriformis Say., Trans. Am. Phil. Soc. 4, 409; Reiche Ann. Ent. 

 7. Manticora Cylind. Say, J. Ac. Nat. Sc. 3, 139. 



And to the Californian one : Amblychila Piccolo minii Reiche, Ann. Ent. Tr. 8, 

 560, tab. 19 ; Mann. Bull. Mosc 1844, 183. A. cylindriformis Lacordaire, Mem. 

 Soc. Roy. Sc. Liege, 1, 95.

Resolved, That a committee of three members be appointed to request 

 a copy of the Address for publication. 



Whereupon the following members were appointed the Committee :
