Silky blackish. Primaries with a faint puri»lisli iclk'ctioii. Trans- 

 verse anterior line indistinct, linear, darker than the j;round color of 

 the wing, medially with a ronnded ontwaid inclination. Keniforiu 

 clear pale-yellowish in both my si)ecimens, without included dots, indis- 

 tinctly darker ringed, contrasting. Transverse i)ostcri()r line linear, 

 dark, tinely dentate, indicated on costa by pale scales; a little projected 

 opposite the cell. Subterminal line distinctly indicated by small whitish 

 lunulated included dots, a little outwardly i)r()|ected over median nerv- 

 ules. A very fine terminal line ; fringes concolorous, neatly interrupted 

 with pale scales. The neat ornamentation may be clearly seen against 

 the almost uniform blackish ground of the piimarie.^, witli attention. 

 lliiul wings much paler, smoky-whitish, with two darker median lines 

 approximating toward internal margin, and a faint <lis<'al mark; ter- 

 minal line and fringes as on primaries. Beneath blackish, ])aliiig 

 toward internal margins, with distinct discal marks and double, neatly 

 and minutely dentated transverse lines. Head and appendages, tho- 

 rax and legs outwardly blackish, concolorous; abdomen paler. Tarsi 

 dotted with pale scales. 



Expanse of wings, liO to 23 mm. = 0.80 to 0.1)0 incli. 



Habitat.— Middle, Central, and Southern States; Texas in March, 

 May, and October; Illinois in July. 



The s^iecies is not common, except in the southern portion of its 

 range, being most often received from Texas. It varies little, except 

 in the distinctness of the maculation, the form described by Mr. Grote 

 being a well marked type which is somewhat less common. Usually 

 the yellow reniform is quite obvious, but sometimes even this disap- 

 pears. A point not mentioned by Mr. Grote is the fact that the black- 

 ish abdomen is usually narrowly pale annulate. 



Tetanolita floridana, new species. 



Ground color a pale hiteous, with variabl}^ distinct smoky powder- 

 ings. Head concolorous with the darker, the thorax with the paler 

 parts of the wing; abdomen somewhat more gray, the edges of the seg- 

 ments paler ringed. Primaries with the markings ill delined, more or 

 less darkened over the costal region, the outer part of subterminal and 

 all the terminal space dusky. Basal line faintly indicated in some 

 specimens. Transverse anterior line single, blackisli, a large outcurve 

 ill thesnbmedian iiiters])ace, else nearly !i|)right. Transverse posteri(u- 

 line slender, dusky, crenulated. obliiuie, nearly iiarallcl with the onter 

 margin. Subterminal line ])ale, more or less intenuptcd. parallel with
