NO. 1203. NEW NOCTUID MOTHS— SMITH. 483 



ing from the co^ta about three-fourths from base and eudiug at about 

 the middle of the inner margin. Within this, the wing is uniform, 

 yellow brown. Beyond the white line is a pale shade which merges 

 gradually into an obscure dusky or smoky shading. A subterminal 

 line of brown spots is traceable through this shading, in most speci- 

 mens. The orbicular is indicated by a black dot. There is a brown 

 line at the base of the fringes. Secondaries, uniform smoky brown. 

 Beneath, smoky, immaculate. 



Expanse, 17 to 19 mm. =0.68 to 0.76 inch. 



Habitat. — Key West, Florida. 



Four males are before me and 1 have seen others. The species seems 

 to be not uncommon, and may have been described as a Deltoid, which 

 it resembles as well in the simple maculation as in the wing form and 

 abnormally developed palpi. 



Type.—Qdit. No. 4815, U.S.N.M. 



DIALLAGMA, new genus. 



Head moderate in size, front broad, little convex, not tufted. An- 

 tennas in the male well ciliated, with longer, bristle-like hair on each 

 side of each joint; in the female simple. Tongue normal. Eyes 

 naked, moderate in size, not prominent. Palpi disproportionately 

 stout and long, straight or somewhat oblique, exceeding the head by 

 its own length; second joint longest, a little arcuate above, clothed 

 with scales directed downward and longer at the tip, so that this is 

 very broad when viewed from the side. As the joint is also thickened 

 laterally, the palpi diverge and do not form a snout. Terminal joint 

 short, stout, subequal, straight or a little oblique upwardly. Thorax 

 small, convex, vestiture scaly,close, forming no tufts. Abdomen well 

 exceeding anal angle of secondaries, untufted. Legs unarmed except 

 for the usual spurs, which are long and stout, vestiture scaly and, 

 though close, quite thick, so that the tibitie especially seem heavy. 

 Primaries rather long, moderate in width, widening rather evenly from 

 base, apex rectangular, outer margin even, friuges long. Venation 

 normal. Secondaries proportionate. Vein 5 well marked though 

 weaker than the others, from the cross vein rather close to 4, but not 

 forming a branch of the median. 



As a whole the moths are somewhat slender and narrow-winged 

 closely scaled, and most marked by the heavy palpi. The genus seems 

 best related to the Eucalypterid series at present. 



86. DIALLAGMA LUTEA, new species. 



Ground color clay yellow, smooth, with rough black powderings from 

 which the markings are formed. Head a little more yellow on the ver- 

 tex, palpi chocolate brown at the sides, collar and disk of thorax irro- 

 rate with brown; but not otherwise ornamented. Primaries with all 

 the lines blackish and more or less broken, a large quadrate blackish 

 patch in the middle of the wing, just beyond the transverse anterior
