AMERICAN COLEOPTERA. 137 



long to Lebia as at present restricted, by the deeply striolate head. 

 Head black, antennas dark, four basal joints paler. Thorax rufo-testa- 

 ceous, intricately rugulose. Elytra deeply striate, intervals more or 

 less convex, black and ornamented as follows with pale testaceous 

 spaces : appendiculata , Chaud., a humeral sub-quadrate space extend- 

 ing inward to the fourth stria and with a small spot appended to the 

 inner angle of the larger one on the third and fourth intervals. The 

 point of humerus is frequently tipped with black ; lateral margin 

 narrowly, apical margin broadly testaceous; analis, Dej., basal and 

 lateral margins narrowly, apical broadly testaceous; humeral stripe 

 short, occupying the basal portion of the intervals between the fourth 

 and sixth striae ; marginella J Lee. similar to analis, but with the 

 markings reduced to a mere trace of each. This variety resembles 

 collaris. Under surface and legs pale testaceous, abdomen darker. 

 EpipleuraD pale. 



It. fuscata, Dej. Spec, i., p. 270; Chaud. Bull. Mosc. 1870, ii., p. 230.— 

 Head piceous, smooth. Antennoe with basal joints pale, outer joints somewhat 

 darker. Thorax finely wrinkled, disc piceous, paler than the head, margin 

 broad testaceous. Elytra moderately elongate, sides arcuate and broader be- 

 hind the middle, surface deeply striate, color pale testaceous with the anterior 

 three-fourths of margin narrowly bordered with black, a scutellar black space 

 occupying the bases of the four inner interspaces, broader than long which 

 rapidly narrows to two interspaces, and at the middle of the elytra again 

 widens to three interspaces, and at the apex again narrows. In many speci- 

 mens a narrow band connects the middle of the hinder dilation with the mar- 

 gin, but this varies in width and is at times absent. Body beneath and legs 

 testaceous. Fourth tarsal joint deeply bilobed. Length .20 — .30 inch; 5 — 

 7.5 mm. 



The smaller variety has the transverse band broad and it resembles 

 some of the more fully ornate varieties of omata, but is readily known 

 by the deeply striate elytra. 



Occurs from Canada to Florida and westward to Missouri. 



Ii. frigida, Chaud. Bull. Mosc. 1870, ii., p. 242. 



This species is unknown to me in nature. The description and fig- 

 ure recall at once specimens of omata with elytra more deeply striate 

 than usual, of which several specimens are before me. Can it be pos- 

 sible that it is merely a variety of L. fuscata f Its length is about 

 .18 inch; 4.5 mm. 



Said by Chaudoir to occur near Boston.
