no. 1645. REVISION OF CERTMX NOCTUIDJE— SMITH. 223 



pletely outlined in yellowish scales. T. p. line very slender, black, 

 single, outwardly denticulate in the interspaces, a little emphasized 

 and thickened just below vein 2. 8. t. line hardly traceable as such; 

 a leaden gray or brown band from inner margin near anal angle with 

 a slight incurve to middle of outer margin. A series of blackish 

 interspaceal terminal marks. Secondaries with disc crossed by ob- 

 scure lighter and darker shade lines. A pair of narrow black extra 

 median lines of which the inner is even or nearly so and the outer 

 forms outward dents in the interspaces between ."> and 6 and G and 7. 

 In the male there is a blackish spot at anal angle from which a bluish 

 shading extends toward the apical angle: in the female a leaden gray 

 or brown band extends from apex to anal angle below the black lines. 

 A series of interspaceal dark or black spots. Beneath yellowish, 

 crossed by numerous brown strigillations. 



Expands, 1.80-2.12 inches=45-53 mm. 



Habitat. — Brownsville, Texas, in June; Marco, Florida, in July; 

 Egmont, Florida, April 29. 



A series of 10 males and 2 females from the above localities; 

 others are in the Schaus collection, IT. S. National Museum, from 

 various South and Central American points. The species is very 

 characteristic and GueneVs descriptions apply perfectly. The speci- 

 mens in the Schaus collection were directly compared with the types 

 by Mr. Schaus, and the determinations correspond with those made 

 by me from the descriptions. There is enough difference between the 

 sexes to justify a separation into species, with limited material. The 

 males are very uniform and very characteristic in color and in the 

 extramedian line of the secondaries. The females are much darker, 

 more like Janata in color, much more strigillate and with the pecu- 

 liarities of extra-median line of secondaries less marked. The only 

 strong point that the two sexes have in common is the yellowish 

 scale edging to the reniform. The denticulate t. p. line, of course, 

 serves to distinguish it from any form of lunata which it might other- 

 wise resemble. 



The femoral tufting of the male is large and the mass of special- 

 ized scales is huge, larger in proportion and actually, than in any 

 other of our species. 



The genital structure of the male is almost symmetrical, the lateral 

 pieces moderate in size and simple in form. The uncus, how- 

 ever, is unusually long, stout, and heavy, transversely somewhat 

 flattened and with a membraneous secondary structure within and 

 parallel to it. 



The female has the anal plate entire and the opening to the 

 copulatory pouch is from the median line at the inferior margin; 

 symmetrical in all respects.
