2 DESCRIPTIONS OF NEW SPECIES. 



fraud dense punctulatis ; pectoribus dense punctatis, pedibus testaceis, 

 femoribus viriditinctis. Long. -27. 



Catskill Mountains, New York ; Mr. Ulke. Resembles in form 

 and appearance E. poh'tus and E. Icevigatus, but differs from both 

 by the color, as well as by the fine golden punctures which cover 

 the head, thorax, margin and tip of the elytra, and also by the 

 more dense punctures of the breast. 



BUETHISA BON. 



3. B. Jlllii. Supra nigro-aenea cupreo-tincta, thorace punctate, latitu- 

 dine breviore, lateribus rotundatis, angulis posticis obtusis subcarinatis, 

 medio sublsevi, linea dorsali haud profunda, basi utrinque inapresso, 

 margine lateral! latiusculo reflexo, elytris thorace latioribus, oblongis, 

 seriatim punctatis, interstitiis 3io et 5to latioribus foveis majusculis 

 interruptis ; subtus nigra. Long. -45 *47. 



Nova Scotia ; Mr. Ulke. The interruption of the 3d and 5th 

 intervals produce a catenated appearance : there are five fovese on 

 the 3d, and three on the 5th interval ; the 7th interval is more 

 elevated than the adjoining ones, but not interrupted. 



I take great pleasure in dedicating this beautiful species to my 

 accomplished friend, Mr. Julius Ulke, whose labors in the field 

 with his brother, Henry Ulke, have produced much advantage to 

 science.

4. D. Sllbpolaris. Obscure senea nitida, capite thoraceque modice 

 punctatis, fronte inedio fovea parva impressa, thorace latitudine paulo 

 "breviore postice angustato, lateribus antice rotundatis, postice sinuatis, 

 angulis posticis rectis carinatis, basi utrinque profunde impresso, elytris 

 elongatis thorace paulo latioribus, striis punctatis haud impressis, inter- 

 Btitio 3io tripunctato ; subtus cum pedibus nigra. Long. -35. 



Hudson's Bay; Mr. Ulke. Allied to the European D. arctica, 

 but differs by the thorax being more narrowed behind, and by the 

 elytra being less dilated, and almost parallel. The genus Diachila 

 is not mentioned in the first part of my classification, as it was not 

 known to be represented in our fauna at the time the work was 

 published. It differs from Blethisa by the last joint of the maxil- 

 lary palpi being elongated as in Elaphrus; and from Elaphrus by 

 the eyes being small, as in Blethisa, and the elytra striate, without 

 large fovese. It appears to me fully entitled to rank as a distinct
