Descriptions of North American species of Coleoptera, presumed to be undescribed. 



By S. S. Haldeman. 



From the difficulty attendant upon the study of insects in the United States, 

 arising from the absence of standard collections, and the impossibility of know- 

 ing what has been done in Europe, the characters here given should, perhaps, 

 be regarded as indicating species unknown to the author, rather than as abso- 

 lutely new to science. 



Ctmindis neglecta. Head and prothorax black, thinly marked with rufous 

 pile ; head punctured; mouth, antennae, and feet rufous : prothorax lengthened, 

 and much contracted behind, scabrous with numerous deep punctures, mesial 

 line and lateral submargin depressed : elytra reddish brown, crenate-striate, in- 

 terstices narrow. 8 millim. long. General appearance of C. pilosa, Say. 



Dromius apicalis. Head black ; prothorax reddish-brown, with a testaceous 

 margin ; elytra brown, with the tip, and a large irregular spot very near the base, 

 pale testaceous : body beneath, legs, antennas, and palpi of the latter color. Not 

 quite 4 millim. long. 



Dromius geminatus. Brown, head black ; antennae, a large oval spot near 

 the base of the elytra, and a small circular one at the inner extremity, testaceous. 

 4 mill. long. 



Plochionus timidus. Dull reddish brown above : antennae, legs, lower sur- 

 face and lateral margins of the prothorax and elytra, testaceous: elytra wide, deeply 

 striate, interstices convex. 8 mill. long. Var. Base of the elytra, and a large

 Hentz MS. 



Lebia brunnea. Fuscous, head and pronotum blackish : thorax beneath, mar- 

 gin of the pronotum, palpi, 3 basal articulations of the antennae, a spot anterior 

 to the middle, and equidistant from the suture and limb, and a smaller obsolete 

 one at the tip of the elytra, pale testaceous. 42 mill. long. 



Coptodera fasciata. Head and prothorax shiningblack, with a tinge of green- 

 ish : beneath very dark brown : tarsi and extremity of antennae pale brown :
