L.. ornata, Say, Trans. Am. Phil. Soc. ii., p. 13; axillaris Dej. Spec, v., p. 

 372; var. marginalia Dej. Spec, p. 373; apicalis Hald., brunnea Hald. Proc. Am. 

 Phil. Soc. 1842, p. 29S. — Head piceous, smooth. Antennae with three basal 

 joints pale, outer joints somewhat darker and slightly thicker. Thorax piceous 

 varying to testaceous, margin paler. Elytra parallel, flat, feebly striate, 

 piceous, lateral margin and apical spot testaceous, and a subhumeral spot of 

 oval form, narrow the base, of the same color. Body beneath and legs testace- 

 ous. Length .18 — .20 inch; 4.5 — 5 mm. 



There appears to be some difference of opinion regarding the 

 synonymy of the species of Say and Dejean. The former author has 

 undoubtedly mixed two species, but refers to two varieties of his typi- 

 cal form which appear to be identical with varieties of Dejean's analis. 

 The typical form of Say is without doubt that briefly described. As 

 is seen above Chaudoir refers marginella, Dej., to this species as a 

 variety although it would seem rather to be a variety of analis and 

 did not Chaudoir have in his cabinet the types of Dejean I should 

 doubt the validity of his determination, but with the type before him 

 his view must be accepted as final. A variety is before me with the 

 thorax pale yellowish testaceous. 



Occurs everywhere in our country.

Dejean's description, as also those of Chaudoir, do not seem to indi- 

 cate any difference between nigripcnnis and collaris except in size and 

 the color of the head and thorax. These characters are ordinarily 

 good, but in the present instance the color of the head and thorax is 

 s6en to vary in our series. The elytra are rather more parallel than 

 in ornata and almost totally black in color, the lateral and apical mar- 

 gins being narrowly bordered with pale brown. The under surface 

 and legs are pale testaceous or sometimes a little darker. Antennae 

 rather short, basal joints pale, outer joints brownish. Length .20 

 inch; 5 mm. 



Occurs in the Middle and Southern States, but rare.

Chaudoir is in error in supposing that Dr. LeConte has confounded 

 the analis and axillaris. The form which has served as the type of 

 the latter species is identical with that of Dejean. The ornata of Le- 

 Conte is the present species. This species and its varieties may be 

 readily known from all the others with ornate elytra, and which be-
