Gorham (Biol. Centr.-Amer. Ill, pt. 2, p. 134) has since been 

 recognized as being fuscula. The secondary sexual characters of 

 the abdomen are not given in the original description of tcsana. 

 hence a comparison of the types is necessary to thoroughly estab- 

 lish the distinctness of the two species ; texana is, however, in the 

 opinion of the writer, entitled to stand as a valid species. In this 

 species the elytral striae are longer, the prothorax much less dis- 

 tinctly punctured and the elytra have besides the pale median 

 fascia (as in* fuscula) the apices pale or each with a pale macula- 

 tion at the apex. This marking is, however, of an evanescent 

 nature, as excellently shown by the series in the collection.

This species has for a long time stood in our lists as a variety 

 of undulata. It is. however, a distinct species, the sexual char- 

 acters of the male abdomen being quite different, the prothorax 

 is less strongly constricted at apex and base, and the elytral punc- 

 tures are much coarser and deeper. In the male the fifth ventral 

 segment is very deeply arcuato-emarginate ; the sixth ventral 

 much longer than wide, the sides nearly parallel, feebly arcuate, 

 apex very deeply emarginate, angles prominent, obtuse, the sides 

 carinate from apex nearly to base, middle deeply longitudinally 

 sulcate from apex to base ; last dorsal narrower but longer than 

 last ventral, sides gradually narrowing to apex, which is sub- 

 truncately rounded with a small but distinct triangular emargi- 

 nation at middle, disk with deeper longitudinal sulcation at middle..

14. Thanasimus undatulus Say, var. nuhilis King-. Term. ; Mich.; 



L. Sup. ; Colo. 



All the specimens are of the variety, which only differs from 

 the typical form in having the elytra black (not narrowly red) at 

 base. The Tennessee specimens are in the three examples smaller 

 than those from the other localities.
