80' PROCEEDINGS OP THE ACADEMY OP 



The rows of large punctures on the elyti;a, which represent the striae cease be- 

 hind the middle, and at the tip only the extremity of the seventh stria is exa- 

 rate : the rows of small interstitial punctures are four and extend nearly to 

 the tip: each of them supports a long erect black hair, as in Bembidium 

 1 ae y ig a t u m, and other long hairs are seen at the margin of the thorax. 

 The anterior tibiae have a scarcely distinct superior denticle, and an acute in- 

 ferior tooth : the apical tooth is long and slightly curved, the spur is nearly as 

 long and curved.

New Orleans, Dr. Schaum. Allied to the preceding, but larger and less 

 robust; the thorax is different in form and not at all transverse: the striae of 

 the elytra are impressed, and the inner ones may be traced to the very tip : the 

 outer ones are obliterated, the eighth is entirely wanting : the marginal ceases 

 at the humerus : the seventh is exarate at the tip as in the preceding. The 

 anterior tibiae are as in the preceding. A few long hairs are seen at the margin 

 of the head and thorax, as in D. s e t o s u s.

Louisiana, very rare: given me by my excellent friend Dr. Schaum, to whom 

 it is dedicated. This species has the form and sculpture of A. o b 1 i q u a t a, 

 but is smaller, with less convex elytral intervals, and only five dorsal punctures. 



3. Clivina viridis Say ; Clivina rostraia Dej. ; Ardislomis rostrata Putzeys ; 

 Ardistomis vicina Putzeys. 



ASPIDOGLOSSA Putz. 



Of this genus is known to me but one species within our territory, A. s u b- 

 aagulata ice, which however varies slightly in the form of the thoraz, so 

 as to account for the list of synonyms, which are as follows: 



Dyschirius subangulatus Chaud. ; Clivina crenaia\De}. ; Clivina bipvstulataX 

 Say. ; Dyschirius humeralis Chaud. ; Aspidoglossa vicina Putzeys ; Aspidoglossa 

 fraterna Putzeys.
