by Acidalia Hbn. (1818, Verz., p. 31) but are not certain as to the 

 correct name to be used in its place; it is very possible, according 

 to Messrs. Prout and Hampson, that Scapula Schr. (which in any case 

 has priority and for which the correct type is said to be ornata Scop.), 

 should be employed. 



LARENTIINAE 



LiTHOSTEGE FUSCATA Grossb. 



After a careful study of the type from Colton, Calif., in Rutgers 

 College Collection and a comparison with several specimens taken 

 with us, we cannot find any distinct characteristics that would sepa- 

 rate this from rotmtdata Pack. ; the wings are rather more suffused 

 with gray than is the case with Packard's type specimen from San 

 Diego, Calif., but only slightly more so than in the type specimen of 

 ariconata Grt. in the Brooklyn Inst. Coll. which is listed as a synonym 

 of rotundata; we can make absolutely nothing of the supposed differ- 

 ence in the course of the three subterminal white lines on which 

 Grossbeck lays stress. We have a good series of specimens from 

 Arizona localities as well as from various S. Californian localities as 

 far north as the San Bernardino region and find that there is as 

 much variation between specimens from any one locality as there is 

 between the types of rotundata Pack., arisonata Grt. and fuscata Grt. 

 The name fuscata may be retained for the suffused forms if desired 

 but we cannot see that it is entitled to specific rank. 



Stam NODES DECEPTivA sp. nov. (PI. XXIII, Fig. 1). 



Front, thorax and abdomen light fuscous, tinged with pink between the 

 antennae and at base of collar ; primaries deep orange with basal third of costa 

 gray-black ; a large, broadly triangular spot of same color on costa beyond

 gray black with irregular inner edge closely approached to apex of costal tri- 

 angle ; fringes dusky, cut with white. Secondaries orange with gray-black 

 markings as follows; a basal spot, the basal half of costa which is joined to 

 two spots in the cell, a large oblong patch on costa near apex, a larger patch 

 above inner margin joined at its extremities to the margin and enclosing a spot 

 of orange color, a smaller lunate patch above anal angle and a slight irregular 

 band on central portion of outer margin; fringes dusky partially cut with 

 white. Beneath primaries as above but costa pale ochreous, this color enclosing 

 the outer triangular spot ; secondaries pale ochreous with blackish markings
