A. ractielae n. sp. — Expands 33 mm. Palpi and thorax clothed with long 

 woolly hairs, black at base, light gray towards end, giving these parts a gray ap- 

 pearance ; this gray color is stronger on the patagise posteriorly, at the extremity 

 of the abdomen, and on its sides ; summit of head rust-brown, as is the thorax 

 posteriorly at dorsum ; also a rust-brown tuft dorsally on the first iive segments 

 of the abdomen ; antennae black. Wings semi-diaphanous, smoky gray, loosely 

 and scantily covered with smoky gray scales and hairs; costa narrowly rust- 

 brown half way out from base ; veins lined with black, an extra black line show- 

 ing on the fold of la; a somewhat faint, yet distinct basal cross line, and another 

 beyond cell parallel with outer margin; the outer margin of the cell is darker, 

 thus with the cross-line inclosing a triangular costal space ; hind wings with a 

 corresponding cross-line at middle; beneath much as above, but fainter. 



This insect is very much in appearance like A. lapponaria Bois. 

 of Europe. Mr, Bruce tells me that in England he used to take 

 A. zonaria along salt marshes. A. rachelce he found in grass about 

 some salt springs in Colorado. It is a beautiful insect, the first of 

 its group discovered in America, and I take pleasure in naming it 

 after the wife of its discoverer. 



65. RHAPHIDODEIVIAS n. gen. 

 Type titea Cram. 



Palpi short, loosely scaled, not heavy ; tongue developed, but not 

 strong ; front loosely haired ; antennae of % bipectinate almost to 

 apex, of 9 filiform ; thorax heavy scaled, tufted anteriorly and 

 posteriorly, hairy below ; abviomen hairy scaled, the segments above 

 armed with many chitinous spines; hind tibise of % swollen, without 

 hair pencil, with all spurs ; fore wings without fovea below in % , 

 1 1 veins ; hind wings 5 undeveloped, 6 and 7 separate, 8 separate 

 from cell, 9 wingless. 



Peculiar in the spinous armature of the abdomen, much surpassing 

 in this respect Paleacrifa Riley and Chondrosoma Anker. Phigalia, 

 a European genus, type pedaria Fab., shows the same tendency, but 

 it is not so marked. Phigalia is also much more hairy in vestiture. 

 Species. — R. nevadaria Hulst, n. sp. 

 R. olivacearia Morr. 

 R. titea Cram. 



R. nevadaria n. sp. — Expands 34-36 mm. Very near R. tifen and R. 

 olivacearia : about the size and wing shape of the latter, with the more distinct 

 cross-lines of the former. The fore wings have more of blackish than R. titea, 

 this being more emphasized in the outer shading of the outer line ; all the veins 

 outwardly arelined with black, especially strong beyond outer line; the middle 

 and outer lines merge together at inner margin ; the spinulations of the abdomen 

 are not as strong as in the other species.
