tinned, by the more elongate form, and by the abdomen being not margined. 

 One species of Eusesthetus described by Erichson possesses the last mentioned 

 character, but has the same sculpture as the other species. The antenna? in 

 S t i c t o c r a n i u s are not as long as the head and thorax, the second joint is 

 thicker than the third, which is equal to the fourth : 5 8 rounded, nearly equal, 

 ninth very slightly larger, tenth and eleventh broader, the former nearly square, 

 the latter one-half longer, obtusely rounded at tip. The head is large, wider than 

 its length, moderately convex, very coarsely punctured; the front is trans- 

 versely impressed, and the anterior margin is elevated ; the eyes are moderate 

 in size, not very prominent, and are coarsely granulated. Thorax a little 

 longer than wide, obovate, gradually narrowed behind ; convex, smooth, with a 

 short impressed line at the middle, four discoidal punctures, forming a quin- 

 cunx, and four others on each side ; there is also a transverse range of punc- 

 tures near the base; the two posterior' dorsal punctures are elongated, resem- 

 bling the short medial line. Elytra convex, wider but not longer than the 

 thorax, smooth, with a few subsutural punctures, three or four in a short dor- 

 sal series, and three or four others near the side. Abdomen pubescent, cylin- 

 drical, not margined, very finely punctulate, pointed at the tip, one-half longer 

 than the elytra. 



DELEASTER Er. 



D. concolor, piceo-ferrugineus, pedibus testaceis ; capite laevi, postice 

 utrinque oblique impresso, vertice convexo, occipite transversim constricto ; 

 thorace capite vix majore, ovato, basi apiceque truncato, disco subtiliter cana- 

 liculate postice et utrinque ad latera late excavato ; elytris thorace duplo lati- 

 oribus, planis rugose punctulatis subopacis. Long. 7-5 mm. 



Mr. Ulke received two specimens from San Francisco, California, one of 

 which he has liberally given to me ; it resembles the European D. dichrous 

 in size, form and sculpture, but differs by the head and abdomen not being* 

 darker than the thorax and elytra. 



ANTHOPHAGUS Grav. 

 A. vertical is Say. I found on the shores of Lake Superior two speci- 

 mens of a variety of this species, in which the body is of a uniform black color, 

 the legs alone being brownish-testaceous ; a similar specimen occurred in Ly- 

 coming County, Pennsylvania, on the banks of the Loyalsoc. 



LESTEVA Latr. 



L. fusconigra Ma'clin, Bull. Mosc, 1853, 193; Phloeopterus fuse. Motsch. 

 Et. Ent., 1852, 78. 



A specimen of this remarkable insect was collected in El Dorado County, Cali- 

 fornia, and sent me by Dr. J. G. Cooper. 



AMPHICHROUM Kraatz. 



A. laevicolle, nitidum, thorace ovali, latitudine breviore, angulis valde 

 rotundatis, disco convexo impunctato, lateribus depressis, elytris thorace duplo 

 longioribus, haud dense punctatis breviter pubescentibus, abdomine lsevi, bre- 

 viter pubescente. Long. 3-75 5 mm. 



Mas, minor, niger, thorace elytrisque piceis, limbo omni testaceo, ano, anten- 

 narum basi, palpis pedibusque flavo-testaceis. 



Femina, major, rufo-testacea, capite nigro-piceo. 



I found this species abundant on the flowers of Cratwgus tomentosa, in Lyco- 

 ming County, Pennsylvania. It is closely allied to the California A. f 1 o r i- 

 bundu m Lee, but differs by the thorax being more distinctly transverse, the 

 hind angles more rounded, and the disc free from punctures. The antenna- 

 are a little shorter and less slender. 



Specimens of the male occur in which the elytra are entirely testaceous, but 

 in general the disc is piceous, with the entire margin (including the suture) of 

 each pale.
