testaceous. A black basal dash extend.s to the twice strongly angulated t. a. line, which is gem- 

 inate, the inner more distinct line composed of raised scales. Above the basal dash the 

 humeral space is pale beyond the geminate basal half-line. Median space wide superiorly, 

 owing to the superior wide projection of the distinct and regularly denticulated t. p. line. 

 Orbicular rather large, pale and vague, with clouded center. Costal black marks evident. 

 Median shade apparent by raised darker scales. Reniform vague, bisannulate, stained with 

 deep testaceous. A very narrow black distinct d;tsh at internal angle, broken at the pale con- 

 tinued s. t. line. A third black dash, indicated within s. t. line, opposite the disc. Secondaries 

 fuscous, w"ith the distinct black discal spot and dentate line of the paler uuder-surface reflected.

10 Acronycta sperata, n. s., Plate 2, flg. 1 J , belongs apparently to the section of A. myricae, 

 Guenee. Clear blue-gray, the usual markings of the primaries distinct and erect. T. a. line 

 geminate, waved, component lines divaricate. Orbicular small, very distinct, a blackish void 

 annulet. Reniform well sized, also distinctly but less completely black ringed, crossed by the 

 median shade. T. p. line regularly dentate, nearly straight, as usual inflected below median 

 nervure. No sagittate marks ; s. t. line pale, vague ; a series of minute terminal black marks. 

 Kind wings white, dusted costally ; beneath white, a little dusted, no lines or spots perceivable.

11 This species resembles ohlinita in general appearance, but is easily distinguished by the 

 ehape of the primaries, the apices being less produced, the externa! margin a little straighter. 

 The t. p. line is more distinct and removed further towards the external margin, and there is a 

 more or less obvious streak at internal angle. Perhaps the two are confounded in the Third 

 Annual Missouri Report, p. 71. In this same Report, the re-description of Laphygma 

 frugiperda, Guenee, the corn-bud-w'orm moth of Abbot and Smith, as Prodenia autumnalis, 

 will at least prevent, it is hoped, "Hn this cou7itry,''^ the appearance of scientific descriptions of 

 this variable species " based upon the simple examination of solitary specimens of the perfect 

 insect, tvithout the fact being mentioned.''^ The italics are mine, and the quotations from page 

 5(j of the Third Report. The species alluded to in this Report as " Prodenia commeinae," can 

 certainly not be Abbot and Smith's Commelinae, as this is so large as not to be possibly con- 

 founded with Laphygma frugiperda. 



*- Gr.: " Ev et ^6yxTl. This section is characterized by the long pointed primaries and 

 Bunken head. Vein 5 of the hind wings is a mere fold, and the cell open.
