yo.2.] GROTE ON LITHOPHANE AND NEW NOCTUIDJi:. 203 



^voiild refer the moth as congeneric "uitli noymani; but the tuft is far 

 more prominent and ridge-like, and the abdomen is flattened vrith a dif- 

 fuse basal tuft. Collar deep reddish; thorax purplish black, as dark as 

 in Calocampa. Wings dusky reddish or piui)lish, almost blackish, a 

 little paler than thorax ; all the markings concolorous and indistinct. 

 The lines are of the usual shape, shaded with a paler reddish, making 

 them indistinctly visible ; s. t. line rather more distinct, foUo\\-ed by this 

 paler shading. Median spots with a blackish shade between them 

 representing the median shade, less apparent inferiorly 5 their contour 

 cannot be well made out ; fringes blackish. Hind wings paler, dusky 

 reddish, with concolorous fringes, uneren margin, broken terminal line, 

 faint terminal shade, and discal mark. Abdomen dusky reddish, some- 

 what purplish, darker than hind wings. Beneath, concolorous dusky 

 red, irrorate with black, with a faint even common exterior line, a dis- 

 tinct discal spot on hind wings, and a terminal line broken into dots on 

 jirimaries and lunulated on secondaries. Feet dusky, marked with pale ; 

 antennae bluntly toothed, brushlike. Eximnse, 30 mil. Sauzalito, Mr. 

 James Behrens, February. 



This species seems to differ from the European i-cinctum by the an- 

 tennae not being i)ectinate, and the abdomen being flattened. It differs 

 from CroGigraplia normani by the more i^rominent and sharper mesial 

 tuft and the diffuse tuft at base of the flattened abdomen, which latter 

 is conical in our Eastern species. The antennal structure can only here 

 and there be used to advantage as a generic character in the !N"octuidne. 

 The sides of the thorax are sharper in front in xirccses than in normani^ 

 and the whole body more flattened. The flattened abdomen is of doubt- 

 ful value as a generic character, since certain species of Agrotis seem 

 only to differ iu this particular from the typical form. It may, however, 

 be used later on, when we come to discuss the problem of what may be 

 considered good generic characters in the group. 



Orthosia disticha Grote, Proc. Eut. Soc. Phil. 114, 1875. 



A specimen from Colorado iu Coll. Mr. Hy. Edwards is larger and 

 brighter colored than my type from Texas. The ground-color is paler, 

 more ocher-gray, the median, shade angulated and shading the hinder 

 part of the median space of a deep olive-brown; reniform distinctly yel- 

 lowish. This species may be known by the median shade and the dark 

 .dots inaugurating the sub terminal line. Whether it is Mr. Morrison's 

 Caradrina disticha is now more than doubtful, since I have seen a speci- 

 men from Colorado of the species described by me labeled as a new Or- 

 tliosia by Mr. Morrison. Its identity with the Texan form, aside from a 

 little brighter coloring, cannot, I think, be successfully disputed. 



Orthosia coniadi u. s. 



From Mr. A. Conradi, of Bethlehem, Pa., I have received a specimen 

 of a new species which has much the form of Eadena devastatrix; the 

 abdomen is uutufted, and I refer it provisionally to this genus. A sec-
